I. INTRODUCTION
A. PROCEDURAL OVERVIEW
Petitioner, B/E Aerospace, Inc., filed a corrected Petition (Paper 24,
“Pet.”) to institute an inter partes review of claims 1, 4–7, 9, 10, 12–15, and
17 of U.S. Patent No. 6,536,054 B2 (Ex. 1001, “the ’054 patent”). Patent
Owner, MAG Aerospace Industries, LLC, filed a timely Preliminary
Response (Paper 14, “Prelim. Resp.”).
In the March 26, 2015, Decision to Institute (Paper 26, “Inst. Dec.”),
we instituted trial on claims 1, 4–7, 9, 10, 12–15, and 17 on the following
grounds:
A. Claims 1, 4–7, 9, 10, 12–15, and 17 under 35 U.S.C. § 103(a) over
Gregory1 and Kendall;2
B. Claims 1, 4–7, 9, 10, 12–15, and 17 under 35 U.S.C. § 103(a) over
Stewart,3 Groombridge,4 and Gregory.
Subsequently, Patent Owner filed a corrected Patent Owner Response
(Paper 46, “PO Resp.”), and Petitioner filed a Reply (Paper 67, “Pet.
Reply”).5
Patent Owner did not file a motion to amend.
Patent Owner filed a motion for observation on cross–examination of
Dr. Dershowitz and a corrected motion for observation on cross-examination

2 Kendall, Ex. 1013, US 5,231,706 (Aug. 3, 1993).
3 Stewart, Ex. 1018, US 4,710,988 (Dec. 8, 1987).
4 Groombridge, Ex. 1019, US 4,162,548 (July 31, 1979).

of Mr. Hallmark. Papers 81, 86. Petitioner filed a response to each. Papers
91, 92. This information was factored into our Decision.
Oral hearing was held on Thursday, November 19, 2015, and a
transcript of the oral hearing is included in the record.6 Paper 99 (“Tr.”).
For the reasons that follow, we determine that Petitioner has shown by
a preponderance of the evidence that claims 1, 4–7, 9, 10, 12–15, and 17 of
the ’054 patent are unpatentable.

B. RELATED PROCEEDINGS
Patent Owner asserted the ’054 patent against Petitioner in MAG
Aerospace Industries Inc. v. B/E Aerospace Inc., Case No. 2:13-cv-06089-
SJO-FFM (C.D. Cal.). Pet. 1; Paper 5, 1.
The parties in the case at hand are involved in two other inter partes
proceedings: IPR2014-01510 (challenging U.S. Patent 6,353,942 B1, “the
’942 patent”), and IPR2014-01513 (challenging U.S. Patent 6,536,055 B2,
“the ’055 patent”).7 The ’055 patent (application No. 10/061,681) is a
continuation of the application that became the ’942 patent (application No.
09/713,892). IPR2014-01513, Ex. 1001, (63). The ’054 patent contains
similar subject matter, but is not in a continuity chain leading to either the
’942 patent or the ’055 patent. Ex. 1001, (63).

6 The hearing was held with the hearing for IPR2014-01510 and IPR2014-
01513. Petitioner’s demonstrative exhibits are at Exhibit 1107 (redacted)
and 1108 (unredacted). Patent Owner’s corrected demonstrative exhibits are
at Exhibits 2071.
7 At times each party filed papers that were applicable to all three cases, and
in those papers only cited to the papers and exhibits of IPR2014-01510. In
this decision we attempt to cite to the papers and exhibits of the case at hand.

II. PRELIMINARY MATTERS
Before addressing claim construction and patentability we provide
additional procedural details, and resolve a Motion to Exclude Evidence by
each party.

A. ADDITIONAL PROCEDURAL DETAILS
On May 5, 2015, Petitioner submitted a motion to submit
supplemental information (“the proffered evidence”) under 37 C.F.R.
§ 42.123(a), along with a motion to seal these exhibits. Papers 32, 33.
Patent Owner submitted an opposition to each motion. Papers 34, 35. We
denied Petitioner’s Motion to Submit Supplemental Information because
Petitioner did not explain how the proffered information relates to any claim
subject to a ground of unpatentability for which trial was instituted.8
On October 2, 2015, at Petitioner’s request, a conference call was held
regarding the proffered information denied entry as supplemental
information. During that call, Petitioner asserted that the proffered evidence
demonstrates prior inconsistent statements by several of Patent Owner’s
witnesses in the proceeding at hand, and for that reason Patent Owner must
serve the proffered evidence as routine discovery. See Paper 61 (order), 63
(transcript). We directed the parties to attempt in good faith to determine
what, if any, portion of the proffered evidence demonstrated inconsistencies
as alleged. Paper 61, 4.

8 See IPR2014-01510, Paper 37, 5. This decision was entered as Paper 37 in
IPR2014-01510, but was mistakenly not entered in this inter partes review.
As stated on the cover of that order, the decision applies to this inter partes
review.
IPR2014-01511
Patent 6,536,054 B2

5
The parties were unable to reach agreement, and the Board conducted
a second call on the matter. See Paper 64 (order), Paper 65 (transcript). We
determined that such an order is not a matter of discovery because Petitioner
already had the proffered evidence from the related litigation. Paper 64, 4.
For this, and a variety of other reasons, the Board denied Petitioner’s
request. Id. Petitioner did not file a timely request for reconsideration. See
37 C.F.R. § 42.71(d)(1).
The proffered evidence was later filed with Petitioner’s Reply. Patent
Owner’s Motion to exclude that information is discussed below.

B. PETITIONER’S MOTION TO EXCLUDE EVIDENCE
Petitioner moves to exclude: (1) the unpatentability opinions of Patent
Owner’s declarant, Mr. Anderson (Ex. 2021), and (2) “certain statements” in
Patent Owner’s opposition papers.9 Paper 77, 2–3. Patent Owner filed an
Opposition to the Motion (Paper 89), and Petitioner filed a Reply to the
Opposition (Paper 93). For the reasons that follow, Petitioner’s motion is
denied.
1. Anderson Declaration
The Anderson Declaration was filed with Patent Owner’s Response
on July 13, 2015.

9 This file contains both the Anderson Declaration (Ex. 2021) and the
Anderson Deposition (Ex. 1052).
IPR2014-01511
Patent 6,536,054 B2

a) Objections10
Petitioner identifies the following items or actions as including
objections:
(1) e-mail correspondence dated October 2, 2015, to
October 15, 2015 (filed as Ex. 1072 on October 16,
2016);
(2) conference calls with the Board on October 2,
2015, and October 9, 2015 (Papers 63, 65, respectively);
(3) Mr. Anderson’s Deposition (Ex. 1052, filed
October 16, 2015); and
(4) Paper 48 (Petitioner’s Objections to Evidence).
Paper 77, 2.11
Items (1)–(3) do not properly include objections because they were
not timely filed by Petitioner.12 See 37 C.F.R. §42.64(b)(1).
The fourth item, Paper 48, was timely served.13 See Paper 48, 24; PO
Resp. 54. In Paper 48, Petitioner objected to Exhibits 2019–2043, 2048–
2053, and 2055, and included “general objections” applicable to all of these
Exhibits. Paper 48, 1–2. With regard to the Anderson Declaration (Ex.
2021) in particular, Petitioner lists the rules and Federal Rules of Evidence
that are the grounds for the objection, and states:

10 After May 19, 2015, objections must be filed, not just served. See 37
C.F.R. § 42.64(b)(1), revised 80 Fed. Reg. 28561.
11 Petitioner’s motion references the papers and exhibits of IPR2014-01510,
we have inserted the paper and reference numbers of the corresponding
papers and exhibits in IPR2014-01511.
12 After May 19, 2015, objections were filed, not served. See 37 C.F.R.
§ 42.64(b)(1), revised 80 Fed. Reg. 28561.
13 Paper 48 was filed on July 20, 2015, and Patent Owner’s Response was
filed on July 13, 2015.

This exhibit is irrelevant, cumulative, and/or prejudicial to the
issues on which IPR is progressing. This exhibit does not present
underlying facts or evidence. This exhibit reflects statements
made without personal knowledge. This exhibit reflects opinions
for which the factual bases for those opinions have not been
disclosed, and for which the expert used unreliable analysis and
methods. See also the discussion of objections based on these
rules in Section II.A above [the “general objections”],
incorporated herein by reference.
Id. at 4; see also Paper 93, 1 (repeating this assertion).
Petitioner’s “general objections” apply to the exhibits as a whole
without identifying a particular portion of an exhibit, and in fact, leave it to
the reader as to whether an objection applies to a particular exhibit. See,
e.g., Paper 48, 1–2 (“Petitioner objects to each and every exhibit that . . .”).
We agree with Patent Owner’s characterization that Petitioner submitted
boilerplate objections. Paper 89, 1. Further, Petitioner’s Motion is not based
on an asserted objection. For example, Petitioner’s Motion argues that
Mr. Anderson’s opinions are irrelevant because they are based upon an
incorrect claim construction, but Petitioner did not object on that basis. See
Paper 77, 3; Paper 48, 4. Petitioner’s objections did not identify the grounds
for the objection with sufficient particularity to allow Patent Owner to
correct in the form of supplemental evidence. 37 C.F.R. §42.64(b)(1); see
also Paper 89, 1–5 (Patent Owner arguing Petitioner did not object with
sufficient particularity).
Petitioner contends the objections have sufficient particularity. See
Paper 93, 1–2 (citing Hayward Indus., Inc. v. Pentair Water Pool and Spa,
Inc., Case IPR2013-00287 (PTAB Dec. 17, 2013) (Paper 15) (non-
precedential). This citation is not persuasive because in Hayward no
IPR2014-01511
Patent 6,536,054 B2

8
motions were filed and no determination was made so that the Board’s
comment was an observation and not a ruling. Id.
The lack of an effective objection is sufficient basis to deny
Petitioner’s Motion. See 37 C.F.R. §§ 42.20(c), 42.22, 42.64(c). Despite
this deficiency, we consider the merits of Petitioner’s Motion.
b) Relevance
Petitioner contends that Mr. Anderson’s opinions are based on an
incorrect claim construction, and for that reason are irrelevant under Federal
Rules of Evidence (FREs) 401 and 403. Paper 77, 4–7; Paper 93, 2–4. We
take this as an assertion that the evidence is inadmissible under FRE 402.
Our decision does not involve a jury. For that reason, Petitioner’s
citation to a jury case excluding improper claim construction is not
persuasive. See, e.g., Paper 77, 4 (citing Liquid Dynamics Corp. v. Vaughan
Co., Inc., 449 F.3d 1209, 1224 n.2 (Fed. Cir. 2006)). Further, Petitioner’s
citation to a district court case that excluded an improper claim construction
from consideration on infringement is also unpersuasive. See id. (citing
Chicago Mercantile Exch., Inc. v. Tech. Research Grp., LLC, 782 F. Supp. 2d
667, 673 (N.D. Ill. 2011)). In Chicago Mercantile, the court held that an
expert’s testimony based on an improper claim construction would not be
relevant at trial. Id. Here, in contrast, we construe the claims as part of this
final decision. See Paper 89, 5–7 (correctly noting both that the Board’s
claim construction in an institution decision is preliminary, and unlike most
district court cases, the Board’s final decision addresses claim construction
and patentability). Consequently, evidence regarding claim construction,
such as the Anderson Declaration, remains relevant.
IPR2014-01511
Patent 6,536,054 B2

9
Further, Petitioner does not explain persuasively how the probative
value of the Anderson Declaration is outweighed by any of the dangers of
unfair prejudice enumerated in FRE 403. See Paper 77, 4–7.
c) FRE 702/703
Petitioner contends that the methodology of Mr. Anderson’s analysis
is fundamentally unreliable and should be excluded in support of the Board’s
“gatekeeping” role. Paper 77, 7–9; Paper 93, 4. Petitioner makes several
contentions in support of this argument.
First, Petitioner contends that Mr. Anderson indicated that he did not
write his declaration and that he did not review the Petition prior to filing.
Paper 77, 8 (quoting an unidentified portion of Mr. Anderson’s Deposition at
Exhibit 1052). We agree with Patent Owner that Petitioner’s contention
takes Mr. Anderson’s testimony out of context. See Paper 89, 10.
Mr. Anderson testified that he prepared his Declaration for these proceedings
by: discussions with counsel, reviewing materials, preparing notes, and
several iterations of reviewing and editing those notes to produce a product,
that in turn was used by another to prepare the Declaration. Ex. 1052,
17:19–19:23.
Second, Petitioner contends that Mr. Anderson indicated that he did
not review the Petition prior to filing. Paper 77, 8 (quoting an unidentified
portion of Ex. 1052). Indeed, Mr. Anderson stated at his deposition that he
did not review the Petition for this case; however, Petitioner ignores that
Mr. Anderson stated that he reviewed the Institution Decision. See Ex.
1052, 30:13–20. Further, Petitioner fails to explain persuasively how
Mr. Anderson’s failure to review the Petition renders Mr. Anderson’s
Declaration unreliable.
IPR2014-01511
Patent 6,536,054 B2

10
Third, Petitioner contends that in “concurrent litigation” Mr. Anderson
offered inconsistent testimony regarding claim scope. Paper 77, 8. Even if
true, Petitioner has not explained cogently how a prior inconsistency renders
the Anderson Declaration inadmissible.
Petitioner’s assertions do not persuade us that the Anderson
Declaration is unreliable. We note that the policy considerations for
excluding expert testimony, such as those implemented by the gatekeeping
framework established by the Supreme Court in Daubert v. Merrell Dow
Pharms., Inc., 509 U.S. 579 (1993), are less compelling in bench
proceedings such as inter partes reviews than in jury trials. See, e.g., Volk v.
United States, 57 F. Supp. 2d 888, 896 n.5 (N.D. Cal. 1999); In re Bay Area
Material Handling, Inc., No. C 95-1163 VRW, 1995 WL 729300, at *6
(N.D. Cal. Dec. 4, 1995).
Consequently, Petitioner has not demonstrated that the Anderson
Declaration (Ex. 2021) should be excluded. See 37 C.F.R. §§ 42.20(c),
42.22, 42.62(a), 42.64.
2. Statement’s in Patent Owner’s Opposition Papers14
As explained above regarding the proffered evidence, Petitioner
contends that Patent Owner failed to serve that evidence as routine discovery
information that is inconsistent with positions Patent Owner has taken in this
proceeding. In this Motion, Petitioner argues that the allegedly inconsistent
positions in the Patent Owner Response should be excluded. Paper 77, 9–11
(providing two alleged examples, and citing 37 C.F.R. § 42.51(b)(1)(iii)).

14 Although not explicit, Petitioner is apparently referring to the Patent
Owner Response.
IPR2014-01511
Patent 6,536,054 B2

11
a) Objections
As discussed above, only Paper 48 was timely served. There,
Petitioner presents objections by Exhibit and makes reference to “any
reference to/reliance thereon.” See, e.g., Paper 48, 2 (objecting to Exhibit
2019 and any reference to or reliance thereon). Such identification lacks
specificity. More importantly, this Motion seeks to exclude portions of the
Patent Owner Response based upon a failure to provide inconsistent
information, but that basis was not identified as an objection. See Paper 48.
Petitioner’s objections did not identify the grounds for the objection with
sufficient particularity to allow Patent Owner to correct in the form of
supplemental evidence. 37 C.F.R. §42.64(b)(1); see also Paper 89, 1–5
(Patent Owner arguing Petitioner did not object with sufficient particularity).
The lack of an effective objection is sufficient basis to deny
Petitioner’s Motion. See 37 C.F.R. §§ 42.20(c), 42.22, 42.64(c). Despite
this deficiency, we consider the merits of Petitioner’s Motion.
b) Alleged Failure to Provide Inconsistent Information
Petitioner’s request to exclude statements by Patent Owner that are
inconsistent with testimony and evidence adduced during the district court
litigation relates to a prior order in this case. Paper 77, 9–11. Specifically,
during a conference call regarding Patent Owner’s allegedly inconsistent
statements, the Board cautioned Patent Owner that, “the solution for
[presenting statements without submitting known inconsistent evidence] can
be that the statement that you initially relied on could be expunged or not
used in your favor.” Id. at 9 (citing Paper 63, 32:22–33:2). Indeed, where a
party advances a position in a proceeding, and that party refuses to serve on
the opposition information within that Party’s knowledge that is relevant,
IPR2014-01511
Patent 6,536,054 B2

12
non-privileged, and inconsistent with that position, the Board may expunge
or not consider that position. See 37 C.F.R. §§ 42.5, 42.51(b). However,
this is not a situation where one party advances a position and withholds
from the other party information that is inconsistent with that position.
Rather, Petitioner had the information; it was obtained in the related
litigation. The following additional circumstances also bear on our
determination.
As explained above, we considered the proffered evidence both as
supplemental information and as routine discovery. We denied Petitioner’s
Motion to Submit Supplemental Information because Petitioner, as the
moving party, did not demonstrate the relevance to any claim subject to a
ground of unpatentability for which trial was instituted.15 We denied
Petitioner’s request that we order Patent Owner to serve the documents as
routine discovery because Petitioner already had the documents from the
related litigation. Paper 64. Petitioner did not avail themselves of the
opportunity to seek reconsideration of either determination, and nothing in
this record calls those determinations into doubt.
Since submittal of Petitioner’s Motion to Exclude, Petitioner
submitted the proffered evidence in conjunction with Petitioner’s Reply in
response to Patent Owner’s Response. Further details are provided in the
analysis of Patent Owner’s Motion to Exclude that evidence.

15 See IPR2014-01510, Paper 37, 5. This decision was entered as Paper 37
in IPR2014-01510, but was mistakenly not entered in this inter partes
review. As stated on the cover of that order, the decision applies to this inter
partes review.
IPR2014-01511
Patent 6,536,054 B2

13
The record now contains Petitioner’s proffered evidence so that we
may weigh it against Patent Owner’s allegedly inconsistent statements.
Consequently, given these circumstances, Petitioner has not demonstrated
that certain statements in the Patent Owner Response should be excluded.
See 37 C.F.R. §§ 42.20(c), 42.22, 42.62(a), 42.64.

C. PATENT OWNER’S MOTION TO EXCLUDE EVIDENCE
Patent Owner filed a Motion to Exclude (1) the Dershowitz
Declaration and Reply Declaration, and (2) the Hallmark Declaration and
associated exhibits. Paper 83. Petitioner filed an Opposition to the Motion
(Paper 90), and Patent Owner filed a Reply to the Opposition (Paper 94).
For the following reasons, Patent Owner’s motion is denied.
1. Declaration & Reply Declaration of Dr. Dershowitz
a) Entire Declarations16
The Dershowitz Declaration (Ex. 1027) was submitted with the
Petition on September 16, 2014. Patent Owner’s objections were timely
served on April 9, 2015, and identified the grounds for each objection with
sufficient particularity.17 See Ex. 2066, 8–10, 20; 37 C.F.R. §42.64(b)(1).
The Dershowitz Reply Declaration (Ex. 106818) was submitted with
Petitioner’s Reply. Patent Owner’s objections were timely served, and

16 Here we address the objections to the Dershowitz Reply Declaration as a
whole and we address paragraph 56 separately below.
17 As mentioned above, our Decision to Institute was entered on March 26,
2015. Prior to May 19, 2015, objections were served, not filed. See
37 C.F.R. § 42.64(b)(1), revised 80 Fed. Reg. 28561.
18 Exhibit 1073 is a redacted version of Exhibit 1068.
IPR2014-01511
Patent 6,536,054 B2

14
identified the grounds for each objection with sufficient particularity. Paper
73, 19–21, 26–27; 37 C.F.R. § 42.64(b)(1).
Patent Owner contends that Dr. Dershowitz does not qualify as a
person of ordinary skill in the art, and does not qualify as an expert under
FRE 702. Paper 83, 4–8. Patent Owner makes a variety of assertions
regarding Dr. Dershowitz’s qualifications, including that he lacks hands-on
experience with vacuum toilets, and that, contrary to his representations, his
patents do not relate to vacuum toilets. Id. at 5–7.
Even accepting Patent Owner’s assertions as true, we are not
persuaded that Dr. Dershowitz’s testimony should be excluded. To testify as
an expert under FRE 702, a person need not be a person of ordinary skill in
the art, but rather may be “qualified in the pertinent art.” See Paper 90, 7–
12; Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64
(Fed. Cir. 2008); Mytee Prods., Inc. v. Harris Research, Inc., 439 F. App’x
882, 886–87 (Fed. Cir. 2011) (non-precedential) (upholding admission of the
testimony of an expert who “had experience relevant to the field of the
invention,” despite admission that he was not a person of ordinary skill in
the art). Further, there need not be a perfect match between the expert’s
qualifications and the patent at issue. See SEB S.A. v. Montgomery Ward &
Co. Inc., 594 F.3d 1360, 1373 (Fed. Cir. 2010).
As explained below, the challenged claims relate to vacuum toilets.
We agree with Petitioner that Dr. Dershowitz is qualified to provide his
opinions for this case. Paper 90, 2–5. For example, Dr. Dershowitz has a
Bachelor’s, Master’s, and Doctorate Degree in Aeronautics and Astronautics,
each from Massachusetts Institute of Technology. Ex. 1025, 1.
Dr. Dershowitz has experience in aircraft and spacecraft systems, to include
IPR2014-01511
Patent 6,536,054 B2

15
teaching as a certified flight instructor and a commercial airline license. Id.
at 1–2. Dr. Dershowitz has numerous licenses and certifications, to include:
registration as a professional Mechanical Engineer and as an Aeronautical
Engineer. Id. at 1–2. Dr. Dershowitz’s qualifications align with the
challenged subject sufficiently so that his knowledge is helpful in
understanding the evidence and determining facts in issue.
Consequently, Patent Owner has not demonstrated that the entire
Dershowitz Declaration (Ex. 1027) or Reply Declaration (Ex. 1068) should
be excluded. See 37 C.F.R. §§ 42.20(c), 42.22, 42.62(a), 42.64.
b) Paragraph 56 of the Dershowitz Reply Declaration
Patent Owner seeks to exclude paragraph 56 of the Dershowitz Reply
Declaration (Ex. 1068).19 Paper 83, 8–9. According to Patent Owner,
paragraph 56 is testimony by Dr. Dershowitz regarding “intent, motive, or
state of mind, or evidence by which such state of mind may be inferred” of
the inventors of the ’054 patent, and such testimony by an expert is
inadmissible under the relevancy provisions of FRE 402 and 403. Id. at 8–9.
Patent Owner also contends that this portion of the Reply Declaration should
be excluded under FRE 702 because it simply recites the testimony of others
and is not based on Dr. Dershowitz’s specialized knowledge. Id. at 9.
Patent Owner did not make an effective objection with regard to the
paragraph at issue. Specifically, Patent Owner made general objections
based on FREs 402, 403, 701, 702, and 703, but did not mention paragraph
56, nor testimony regarding state of mind. See Paper 73, 19–21, 26–27.
Consequently, Patent Owner did not provide sufficient particularity to permit

19 Exhibit 1073 is a redacted version of Exhibit 1068.
IPR2014-01511
Patent 6,536,054 B2

16
Petitioner to correct in the form of supplemental evidence. See 37 C.F.R.
§42.64(b)(1). The lack of an effective objection is sufficient basis to deny
this portion of Patent Owner’s Motion. See 37 C.F.R. §§ 42.20(c), 42.22,
42.64(c). Despite this deficiency, we consider the merits of this portion of
Patent Owner’s Motion.
Patent Owner contends that Dr. Dershowitz’s testimony in paragraph
56 reflects the subjective intent of the inventors. Paper 83, 8–9. We
disagree with this characterization.
Paragraph 56 does not contain an explicit statement regarding the state
of mind of the inventors of the ’054 patent, nor is such fairly implied. The
only disclosure regarding the inventors is Dr. Dershowitz’s statement that he
reviewed the testimony of the inventors in the underlying litigation and this
testimony further confirms that his opinion that the challenged claims are not
limited to vehicular applications is correct. Ex. 1068 ¶ 56. We agree with
Petitioner that Dr. Dershowitz may identify the basis for his opinion. See
Paper 90, 13. Dr. Dershowitz does not identify the particular inventor
testimony involved, and more importantly, Dr. Dershowitz does not explain
why the inventor’s testimony confirms his opinion.
Patent Owner has not persuaded us that the paragraph at issue
improperly implies the state of mind of any inventor or permits
Dr. Dershowitz to simply repeat the testimony of another. Consequently, we
deny Patent Owner’s Motion to Exclude paragraph 56 of Exhibit 1068 on
this basis as well. See 37 C.F.R. §§ 42.20(c), 42.22, 42.64(c).

2. Hallmark Declaration and associated Exhibits
Patent Owner seeks to exclude paragraphs 86–102 of the Hallmark
Declaration (Ex. 106920) and Exhibits 1057–1063. Paper 83, 9–10. This
information is the proffered evidence discussed above.
Each of these exhibits was filed on October 16, 2015, in association
with Petitioner’s Reply. Patent Owner’s timely filed objections to these
Exhibits and identified the grounds for each objection with sufficient
particularity. Paper 73 (filed Oct. 19, 2015), 7–16, 21–22; 37 C.F.R.
§ 42.64(b)(1).
In the evidence at issue, Mr. Hallmark states that he is an expert in
aircraft maintenance and repair. Ex. 1069 ¶ 4. The paragraphs at issue are
titled “VIII. Review of Service Documentation.” Id. at i, 29, ¶¶ 86–102.
Mr. Hallmark explains that Service Bulletins (“SB’s”) are documents
provided by a component manufacturer, such as Patent Owner, describing
maintenance or a particular service task to be performed on a specific
component. Id. ¶ 87. Mr. Hallmark discusses the content of SB’s at Exhibits
1058–1063. Exhibit 1057 is an SB index.
a) Relevance
As discussed above, Patent Owner acknowledges that the SB’s found
at Exhibits 1057–1063 are the same documents that were denied entry as
supplemental information. See Paper 83, 10. According to Patent Owner,
these exhibits are confidential internal documents and therefore do not relate
to any of the prior art at issue nor are they part of the knowledge of one of
ordinary skill in the art. Thus, Patent Owner reasons, these documents are

20 A redacted version is filed as Exhibit 1074.
IPR2014-01511
Patent 6,536,054 B2

18
irrelevant under FRE 402 and 403. Id. at 10–11. Regarding Mr. Hallmark’s
Declaration, Patent Owner contends that Mr. Hallmark did not perform
repairs before the priority date, but did so in 2014 for the District Court
litigation. Id. at 12. Patent Owner also contends that Mr. Hallmark did such
repairs in an office setting rather than on the aircraft. Patent Owner
concludes that for these reasons Mr. Hallmark’s testimony in paragraphs 86–
102 is not relevant under FRE 402 or 403. Id.
Petitioner counters that Exhibits 1057–1063 are relevant to Patent
Owner’s secondary considerations arguments put forth in Patent Owner’s
Response. Paper 90, 13–14. Patent Owner responds by repeating that the
Exhibits at issue are not publications because they are confidential
documents, and therefore are not prior art. Paper 94, 4–5. Patent Owner
does not address Petitioner’s contention that the Exhibits are in response to
and relevant considering Patent Owner’s secondary considerations argument.
Patent Owner’s silence is significant, because Patent Owner, as the moving
party, has the burden of proof on its motion. See 37 C.F.R. § 42.20(c).
In the Patent Owner’s Response, Patent Owner contends that the
nonobviousness of the claimed methods is demonstrated by the secondary
considerations of long-felt and unmet need, industry praise, and commercial
success. PO Resp. 45–51. A key factual basis of these assertions is the
contention that:
At the time of the invention of the ’054 Patent, vacuum toilets,
particularly on aircraft, did not include a toilet bowl that could
be replaced in the field while the toilet assembly remained
installed.
PO Resp. 47 (citing Anderson Decl., Ex. 2021 ¶ 16; Jones Decl., Ex. 2022
¶¶ 25–29).
IPR2014-01511
Patent 6,536,054 B2

19
The Hallmark Declaration and the SB’s at issue contain evidence that
has a tendency to make Patent Owner’s contention less probable than it
would be without the evidence, and that fact is of consequence in this action
because we must consider the secondary consideration in our obviousness
analysis. See FRE 401. For example, Mr. Hallmark states that Patent
Owner’s SB 79000XX-38-01, dated March 3, 1992 (Ex. 1061), provides
guidance for replacing rinse valves on toilets “in service” (installed on the
aircraft). Ex. 1069 ¶ 92. Indeed, SB 79000XX-38-01, describes a rinse
valve modification for ENVIROVAC toilets used onboard Boeing 767
aircraft that involves replacing the rinse valve. Ex. 1061, 1–2. The SB
instructions for removing and replacing the rinse valve include shutting off
the aircraft water supply to the toilet assembly (step 1), removing and
replacing the rinse valve (step 6), and turning on the aircraft water supply
(step 11). Id. at 5–6. These steps suggest that the toilet is in the aircraft
during the rinse valve replacement process.
Patent Owner does not explain cogently how the probative value of
the evidence at issue is outweighed by one of the dangers of unfair prejudice
enumerated in FRE 403. See Paper 83, 9–10; Paper 94, 4–5.
In light of this, the evidence at issue is relevant to our analysis of
secondary considerations and responds to arguments raised in the Patent
Owner Response. See FRE 401, 402; 37 C.F.R. § 42.23(a).
Patent Owner has not demonstrated that the evidence at issue should
be excluded based on relevancy concerns.
IPR2014-01511
Patent 6,536,054 B2

20
b) Qualifications as an Expert
Paper Owner contends that paragraphs 106–11521 of the Hallmark
Declaration (Ex. 1069) should be excluded because Mr. Hallmark lacks
experience with the design of waste water systems and vacuum toilets.
Paper 83, 12–13.
Even accepting Patent Owner’s assertions as true, we are not
persuaded that the Hallmark Declaration should be excluded. As explained
above, to testify as an expert under FRE 702, a person need not be a person
of ordinary skill in the art, but rather may be “qualified in the pertinent art,”
and there need not be a perfect match between the expert’s qualifications and
the patent at issue. Mr. Hallmark’s qualifications align with the challenged
subject sufficiently so that his knowledge would be helpful to understanding
the evidence and determining a fact in issue. For example, we note that
Mr. Hallmark has nearly 30 years of experience as a line maintenance
technician, manager, director, and consultant. Paper 90, 5 (citing Ex. 1069
¶¶ 3–14).
Patent Owner has not demonstrated that the evidence at issue should
be excluded. See 37 C.F.R. §§ 42.20(c), 42.22, 42.62(a), 42.64.

D. ASSIGNOR ESTOPPEL
Patent Owner contends that the doctrine of assignor estoppel prevents
Petitioner from seeking inter partes review of the ’054 patent because
Mr. Pondelick, an inventor and assignor of the ’054 patent, is in privity with

21 These paragraphs are found in Section X, pp. 40–45 of Exhibit 1069.
IPR2014-01511
Patent 6,536,054 B2

21
Petitioner. PO Resp. 5, 51–54. Patent Owner acknowledges that the Board
has not applied assignor estoppel to inter partes reviews. Id. at 5 n.1.
As explained in our Decision to Institute, the Board has maintained
consistently that assignor estoppel is not applicable to inter partes reviews.
Inst. Dec. 11 (citing Athena Automation Ltd. v. Husky Injection Molding Sys.
Ltd., Case IPR2013-00290, slip op. at 12–13 (PTAB Oct. 25, 2013) (Paper
18);22 Redline Detection, LLC, v. Star Envirotech, Inc., Case IPR2013-
00106, slip op. at 12˗13 (PTAB June 30, 2014) (Paper 66); Synopsys, Inc. v.
Mentor Graphics Corp., Case IPR2012-00042, slip op. 16–17 (PTAB Feb.
19, 2014) (Paper 60)). We agree with, and adopt, the logic of these cases.
Because we are not persuaded that assignor estoppel, an equitable doctrine,
provides an exception to the statutory mandate that any person who is not
the owner of a patent may file a petition for an inter partes review (see 35
U.S.C. § 311(a)), we decline to dismiss this inter partes review based on the
doctrine of assignor estoppel.

III. CLAIM CONSTRUCTION
A. INTRODUCTION TO THE SUBJECT MATTER
The ’054 patent is titled “Vacuum Toilet Bowl Assembly Having
Removable Bowl.” Ex. 1001 (54). The case at hand deals with toolless
replacement of toilet components, and unlike IPR2014-01510 and IPR2014-
01513, the meaning of Line Replaceable Unit (LRU) is not a significant
issue.

22 See also the associated Final Written Decision in related case Athena
Automation Ltd. v. Husky Injection Molding Sys. Ltd., IPR2013-00167, slip
op. at 6 (PTAB July 23, 2014) (Paper 51).
IPR2014-01511
Patent 6,536,054 B2

22
As background, the Specification describes that repair and
maintenance of conventional vacuum toilets is often overly time consuming
and labor intensive. Id. at 2:17–18. For example, a particular tool might be
required to disconnect and connect each connection. Id. at 1:51˗55.
Modular vacuum toilet 10 shown in Figure 1A is reproduced below:

Figure 1A is a front perspective view of a modular vacuum toilet of
the ’054 patent. Id. at 2:65–67. Modular vacuum toilet 10 generally
includes: frame 20, bowl 36, and valve set 8. Id. at 3:9–11, Figs. 1A, 1B.
IPR2014-01511
Patent 6,536,054 B2

23
Frame 20 supports the components of vacuum toilet 10. Id. at 3:30–
31, Figs 1A, 1B. Top member 28 of frame 20 defines opening 30, and
includes two slots 29 near the rear thereof. Id. at 3:36–37.
Bowl 36 is a receptacle for receiving waste material having a sidewall
38 sized for insertion into opening 30 of frame 20. Id. at 3:47, 53–55. Bowl
36 includes out-turned flange 40 about an upper edge of the sidewall. Id. at
3:48–49. Flange 40 includes tabs 39 sized for insertion through slots 29 in
top frame member 28. Id. at 3:50–52, Fig. 3. Bowl 36 includes outlet 42 in
fluid communication with discharge valve 70. Id. at 3:52–56.
Valve set 8 is comprised of four sub-components: discharge valve 70,
rinse valve 72, flush control unit (FCU) 74, and actuator 76. Id. at 3:21˗24,
Fig. 1.
The Specification describes that a maintenance person can remove
bowl 36, by: using quick disconnect coupling 108a to disconnect first rinse
fluid pipe 35a, manipulating tabs 39 to disengage from slots 29,23 and then
pulling upward on bowl 36 to remove it from frame 20.24 Id. at 4:26˗33. A
new bowl 36 is install by reversing such procedure. Id. at 4:33˗36. This
process can be accomplished quickly without removing and servicing the
entire toilet and without the use of any tools. Id. at 4:6˗9, 36˗38.

23 Tabs 39 may be manipulated manually (without tools). Ex. 1001, 4:4˗9.
24 Bowl 36 is attached to frame 20 by inserting it through opening 30, and
aligning tabs 39 with slots 29 and outlet 42 with collar 47. Ex. 1001,
3:59˗65; Figs. 1, 4. Thus, during removal, presumably, as the maintenance
person lifts bowl 3, outlet 42 will disengage frictionally from collar 47.

10. A method of toollessly replacing a receptacle of a waste
receptacle assembly used in a vacuum toilet system having an
inlet coupling, the waste receptacle assembly including a frame
including at least two vertical supports and a top member
attached to the at least two vertical supports defining an opening,
the frame further having a receptacle engaging portion, the
receptacle being sized for at least partial insertion through the
frame top member opening and having an abutting portion
positioned to engage the receptacle engaging portion of the frame
to maintain the receptacle in an installed position, the receptacle
further having an outlet sized and adapted for releasable sealing
engagement with the inlet coupling, the method comprising:
lifting the receptacle while leaving the frame in place so
that the abutting portion of the receptacle disengages from the
receptacle receiving portion of the frame and the receptacle
outlet disengages from the inlet coupling;
withdrawing the receptacle through the frame top member
opening to remove the receptacle from the frame;
providing a new receptacle sized for at least partial
insertion through the frame top member opening having an
abutting portion positioned to engage the receptacle engaging
portion of the frame and an outlet sized to sealingly engage the
inlet coupling; and
inserting a new receptacle at least partially through the
frame top member opening so that the abutting portion of the new
receptacle contacts the receptacle engaging portion of the frame
and the outlet of the new receptacle engages the inlet coupling.
Claims 4˗7 and 9 depend, directly or indirectly, from independent
claim 1. Claims 12˗15 and 17, depend, directly or indirectly, from
independent claim 10.

C. VACUUM TOILET (ALL CLAIMS)
Claim 1 is directed to a waste receptacle assembly for use in a vacuum
toilet system, and similarly, claim 10 is directed to a method of replacing a
waste receptacle assembly used in a vacuum toilet system.
Petitioner characterizes Patent Owner as attempting to limit the claims
to vacuum toilets. Pet. Reply 4 (referring to Patent Owner’s assertion that
Kendall has nothing to do with vacuum toilets, PO Resp. 20, and to the
testimony of Mr. Anderson, Ex. 1052, 77:14–78:8). According to Petitioner,
only the preamble of claim 1 mentions a vacuum toilet and the body of the
claim does not mention a vacuum toilet. Pet. Reply 4–5.
We need not determine if independent claim 1 and 10 are each limited
to vacuum toilets because we determine that each ground of unpatentability
shows a vacuum toilet that has the structure of claim 1 and can be serviced
by the method of claim 10. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc.,
200 F.3d 795, 803 (Fed. Cir. 1999) (only those terms which are in
controversy need to be construed, and only to the extent necessary to resolve
the controversy).

D. RINSE FLUID DISPENSER (CLAIMS 6 AND 14)
Claim 6 depends from independent claim 1 and claim 14 depends
from independent claim 10. Dependent claims 6 and 14 each recite a “rinse
fluid dispenser.”
In the Decision to Institute we determined that a rinse fluid dispenser
as claimed may take the form of nozzles (e.g., nozzles 46) or known
substitutes such as spray rings. See Inst. Dec. 8–9; Pet. 8; Exhibit 1001,
5:23˗25. Neither party contests this interpretation, and we adopt it here.

IV. PATENTABILITY25
A. INTRODUCTION
A patent claim is unpatentable under 35 U.S.C. § 103(a) if the
differences between the claimed subject matter and the prior art are such that
the subject matter, as a whole, would have been obvious at the time the
invention was made to a person having ordinary skill in the art to which said
subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406
(2007). The question of obviousness is resolved on the basis of underlying
factual determinations including: (1) the scope and content of the prior art;
(2) any differences between the claimed subject matter and the prior art;
(3) the level of ordinary skill in the art; and (4) objective evidence of
nonobviousness. Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).
We consider Patent Owner to have admitted those aspects of these
grounds of unpatentability that are uncontested by Patent Owner and are
material facts. See 37 C.F.R. § 42.23(a) (in an opposition, any material fact
not specifically denied may be considered admitted), § 42.120(a) (the patent
owner response is an opposition).

25 In this analysis, we consider the Dershowitz Declaration (Ex. 1027).
Despite Dr. Dershowitz’s lack of hands-on experience servicing vacuum
toilets, his expertise, as discussed above in the analysis of Patent Owner’s
Motion to Exclude Evidence, provides for useful explanations.

B. OBVIOUSNESS OVER GREGORY AND KENDALL
CLAIMS 1, 4–7, 9, 10, 12–15, AND 17
1. Independent claims 1 and 10
a) Introduction
Independent claim 1 is directed to a waste receptacle assembly that
includes a frame and a receptacle that may be toollessly inserted into and
removed from the installed position independent of the frame. Independent
claim 10 is similar in that it is directed to a method of toollessly replacing a
receptacle of a waste receptacle assembly similar to the waste receptacle
assembly of claim 1. The method includes lifting the receptacle through the
frame top member opening used, providing a new receptacle size for at least
partial insertion through the frame top member opening, and inserting a new
receptacle at least partially through the frame top member opening.
Gregory (Ex. 1015) discloses a vacuum toilet that includes a waste
receptacle (bowl 10). Pet. 32–33 (referring to earlier analysis of Gregory at
9, 22–28); Ex. 1015, 3:23–27. Gregory’s waste receptacle (bowl 10) is
releasably secured in two ways: (1) by a neck that fits into bowl seat 58 in a
snap type relationship, and (2) by tie rods 21 that hook into lugs 20 of bowl
10 and are secured at the opposite end to base plate 14 by a lock nut 43. Pet.
23; Ex. 1015, 3:63–4:3, 5:36–39, Figs. 2, 14; see also PO Resp. 24
(acknowledging that the snap type relationship implies easy reliability).
Kendall (Ex. 1013) discloses a toilet assembly that includes a waste
receptacle (basin 1) having flanges 3 for securing to a frame (cradle like
support means 30). Pet. 12–16; Ex. 1013, 4:21–25, 5:10–20, Fig. 1; Ex.
1027 ¶¶ 104–105. Kendall’s frame includes at least two vertical supports
(spaced apart support walls 32A, 32B) and a top member (top section 33)
that defines an opening and includes a receptacle engaging portion (pins 33A
IPR2014-01511
Patent 6,536,054 B2

29
or attachment bolts). Pet. 32–35; Ex. 1013, 5:10–15, 5:66–6:9, Fig. 1; Ex.
1027 ¶¶ 256–260.
Petitioner contends that it would have been obvious to modify
Gregory’s vacuum toilet assembly by replacing tie rods 21 and lugs 20 with
Kendall’s frame (support means 30) and abutting portion (flanges 3) so that
the waste receptacle may be removed without tools. Pet. 32–33; Ex. 1027
¶¶ 248˗253. We are persuaded that when modified as proposed, the waste
receptacle includes an abutting portion (Kendall’s flanges 3) that engages the
receptacle engaging portion (Kendall’s pins 33A or attachment bolts).
Further, the waste receptacle is sized for at least partial insertion through the
frame top member (top section 33), and the waste receptacle includes an
outlet (neck of Gregory’s basin 1) adapted for releasable engagement (snap
type relationship) with the inlet coupling (Gregory’s bowl seat 58). Such a
modified waste receptacle could be lifted while leaving the frame in place
and withdrawn through the frame top member (Kendall’s top section 33)
without the use of tools. A new receptacle could be at least partially inserted
through the frame top member opening so that the outlet (neck of Gregory’s
basin 1) sealingly engages the inlet coupling (Gregory’s bowl seat 58), and
the abutting portion (Kendall’s flanges 3) contacts the receptacle engaging
portion (Kendall’s pins 33A or attachment bolts of top section 33) of the
frame without the use of tools.
We evaluate this ground of unpatentability further by analyzing Patent
Owner’s contentions and evidence of secondary considerations.
b) Gregory
Patent Owner argues that “[r]emoving and replacing the Gregory toilet
bowl would require tools and significant disassembly, and is not feasible in
IPR2014-01511
Patent 6,536,054 B2

30
the field while the Gregory toilet remains installed.” PO Resp. 14. Patent
Owner asserts that Gregory’s bowl is not an LRU. Id. at 15. Patent Owner
elaborates that Gregory’s bowl is welded and bolted to surrounding parts
including the frame, and is secured by multiple means (e.g., lock nuts). Id.
at 15–18 (citing Ex. 2021 ¶¶ 19–20).
Patent Owner’s contention that Gregory’s bowl cannot be removed
toollessly is not responsive to the asserted ground of unpatentability because
Petitioner proposes to modify Gregory’s waste receptacle to be supported as
disclosed by Kendall. See e.g., In re Merck & Co., 800 F.2d 1091, 1097
(Fed. Cir. 1986) (citing In re Keller, 642 F.2d 413, 425 (CCPA 1981) (one
cannot show nonobviousness by attacking references individually where the
rejections are based on combinations of references)). Further, Patent
Owner’s contention that Gregory’s bowl is not an LRU is inapposite because
claims 1 and 10 do not require the waste receptacle to be an LRU.
Patent Owner’s characterization that Gregory’s bowl is attached by
welding and secured by multiple means is not an accurate characterization of
the reference. Gregory’s bowl 10 is not welded or otherwise permanently
attached to shroud 19; rather, bowl 10 is “releasably seated” in the peripheral
channel formed by bracket 33 and rim wall portion 32 of bowl 10. Ex. 1015,
4:32–35; Fig. 3. Specifically, bowl 10 includes a rim 27 around the
perimeter. Rim 27 includes an outer peripheral wall 31 with an inwardly
folded lower end 32. Seated on lower end 32 and attached by welding or
other suitable means is shroud retaining bracket 33 that extends around the
inner periphery of rim 27. The peripheral channel formed by bracket 33 and
rim wall portion 32 is releasably seated on shroud 19. Ex. 1015, 4:4–35,
Figs 1–3; Pet. 25–28; Pet. Reply 11–12; Anderson Deposition, Ex. 1052,
IPR2014-01511
Patent 6,536,054 B2

31
34:3–36:8; Hallmark Decl., Ex. 1069 ¶ 106 (interpreting Gregory in the
same way). Even if Gregory’s bowl is secured by multiple means, the
claims do not specify a maximum number of securing means, rather the
claims require toolless replacement.
c) Kendall
Patent Owner argues that a person of ordinary skill in the art would
not have considered Kendall. PO Resp. 15, 20–23. Specifically, according
to Patent Owner, Kendall is not analogous art, and “has absolutely nothing to
do with vacuum toilets.” Id. at 15, 20. Further, Kendall is not used in
vehicles, is not connected to a vacuum source, has a different structure, and
does not have precision components or exacting weight and dimension
requirements. Id. at 20–23.
A reference qualifies as prior art for an obviousness determination
under § 103 only when it is analogous to the claimed invention. In re Bigio,
381 F.3d 1320, 1325 (Fed. Cir. 2004); In re Clay, 966 F.2d 656, 658 (Fed.
Cir. 1992). A reference is considered analogous prior art: (1) if the reference
is from the same field of endeavor as the claimed subjected matter,
regardless of the problem addressed, or (2) if “the reference still is
reasonably pertinent to the particular problem with which the inventor is
involved,” even though the reference is not within the field of the inventor’s
endeavor. Bigio, 381 F.3d at 1325.
Petitioner points out, and we agree that Kendall relates to the problem
faced by Patent Owner in that Kendall discloses the ability to repair
components in place, and ease of access for repairs. See Pet. Reply 15; Ex.
1013, 2:36–41, 3:53–56 (the removable shell “facilitates ease of servicing
the fixture”); Ex. 1052, 70:14–71:6; 1068 ¶ 75; Ex. 1001, 1:35–53; see also
IPR2014-01511
Patent 6,536,054 B2

32
Ex. 1001, 1:10–11 (describing that vacuum toilets have both vehicle and
stationary applications). Consequently, Kendall logically would have
commended itself to the problem facing the inventor of the ’054 patent. See
Scientific Plastic Products, Inc. v. Biotage AB, 766 F.3d 1355 (Fed. Cir.
2014); see also In re ICON Health & Fitness, Inc., 496 F.3d 1374, 1379–80
(Fed. Cir. 2007) (holding that a reference may be reasonably pertinent as
analogous art where the matter it deals with logically would have
commended itself to the inventor’s attention).
d) Obviousness
Patent Owner makes several contentions in support of the argument
that Gregory and Kendall would not have rendered the claimed subject
matter obvious. PO Resp. 23–27. In particular, Patent Owner contends that
Gregory seeks to provide resistance to impact, the bowl must be removed
with tools, and nothing in Gregory or elsewhere suggests substituting the
Kendall frame and flanges for Gregory’s flange structure. PO Resp. 23–24
(citing Ex. 2021 ¶¶ 19–20, 29–30, 32). Patent Owner contends that Gregory
teaches away from easy releasability of its waste receptacle because it is
welded to surrounding structures and requires tools to remove it. PO Resp.
24 (Ex. 2021 ¶¶ 19–20). Patent Owner contends that removing Kendall’s
waste receptacle requires tools, and highlights portions of Kendall’s toilet
that would have to be removed. PO Resp. 24–26 (citing Ex. 2021 ¶ 29;
providing a highlighted version of Kendall’s Figure 1).
To the extent that Patent Owner suggests that the reason to combine
the references must be found in Gregory, we disagree. See KSR, 550 U.S. at
418 (2007) (Rejecting the rigid requirement of a teaching, suggestion or
motivation to combine known elements in order to show obviousness).
IPR2014-01511
Patent 6,536,054 B2

33
Patent Owner’s teaching away argument is based on the
characterization that Gregory’s waste receptacle is welded to the toilet
structure. As explained above, such is not the case. Further, that some of
Gregory’s components require tools for removal does not criticize or
discredit having a component being removable without tools. See In re
Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004).
Patent Owner’s contentions regarding Kendall are also unpersuasive.
Mr. Anderson states that Kendall’s basin would not have been toollessly
replaceable in field because a toilet designed for residential use would have
no need for toolless removal of components. Ex. 2021 ¶ 29. Mr. Anderson
does not provides the facts or data for this opinion. The reasons for making
components of a toilet installed in a vehicle removable without tools have
some application to components of a toilet installed in a residence. See Ex.
1013, 8:5–9 (noting that a person of ordinary skill would recognize that
Kendall’s invention has application to other forms of sanitary fixates); Ex.
1001, 1:9–10, 13–14 (describing that the invention of the ’054 patent relates
to toilets in general and vacuum toilets in particular, and that the invention
has stations and vehicle applications).
Patent Owner’s contention that many components of Kendall’s toilet
must be removed in order to remove the waste receptacle is not persuasive.
Petitioner proposes to modify Gregory’s vacuum toilet to have Kendall’s
support structure and waste receptacle flanges, and consequently, the
majority of Kendall’s elements identified by Patent Owner are not part of the
proposed combination.
Patent Owner argues that a person of ordinary skill in the art would
not have combined Gregory and Kendall because a person of ordinary skill
IPR2014-01511
Patent 6,536,054 B2

34
in the art would not have considered Kendall. PO Resp. 29–32. Similarly,
according to Patent Owner, it would make no sense to incorporate aspects of
a household water-power/gravity flush toilet such as Kendall’s into Gregory
vacuum toilet that was intended to withstand shock and vibration. Id. at 30
(citing Anderson Decl., Ex. 2021 ¶¶ 18–21).
As explained above, Kendall relates to servicing toilet components in
place, and is analogous art. Further, Patent Owner’s characterization of
Gregory is too narrow in that it suggests that creating a shock proof toilet
was Gregory’s sole objective. Such is not the case. For example, Gregory
sought to create a toilet that is simple, compact, light in weight, and
economical. Ex. 1015, 1:22–25. The Supreme Court directs us to construe
the scope of analogous art broadly, stating that “familiar items may have
obvious uses beyond their primary purposes, and in many cases a person of
ordinary skill will be able to fit the teachings of multiple patents together
like pieces of a puzzle.” KSR, 550 U.S. at 420. A person of ordinary skill in
the art would recognize that aspects of Kendall’s toilet have application to a
vacuum toilet system.
Patent Owner argues that the rationales proffered by Petitioner are
deficient. PO Resp. 30–32. First, Patent Owner contends that the reasoning
that both references “aim to have simple and compact designs” is a general
goal shared by many, many references and of itself, is insufficient to
motivate a person of ordinary skill to make the proposed modification, and
the contention lacks support in the references. Id. at 30–31 (citing
Dershowitz Decl., Ex. 1027 ¶ 249). Petitioner does not, however, offer such
reasoning as the sole basis for combing the references. See Pet. 33
(explaining, with support from Dr. Dershowitz (Ex. 1027 ¶¶ 249–251), that
IPR2014-01511
Patent 6,536,054 B2

35
the references have similarities in structure, such as central support and a
bowl over a discharge valve, and similar aims, of simple and compact
design); see also Pet. Reply 15; Ex. 1013, 3:53–56 (the removable shell
“facilitates ease of servicing the fixture”).
Further, Patent Owner’s assertion that this reason is not supported by
the references is also unpersuasive. Dr. Dershowitz explains that Gregory
and Kendall each aim for have a simple and compact design. Ex. 1027
¶ 249 (citing Ex. 1015, 1:22–25; Ex. 1013, 2:65–67). Patent Owner does not
directly address the evidence cited in support of Dr. Dershowitz’s opinion,
nor does Patent Owner offer evidence to the contrary. See PO Resp. 30–31.
Second, according to Patent Owner, Dr. Dershowitz’s opinion that
Gregory and Kendall have a similar toilet assembly structure is not a
sufficient rationale because the references “relate to entirely different kinds
of toilet technology.” PO Resp. 31 (referring to Dershowitz Decl., Ex 1027
¶ 250, and citing Anderson Decl. Ex. 2021 ¶ 30 for support). The cited
portion of the Anderson Declaration makes the conclusory statement that
there is “no similarity between the architecture and operation of these two
toilets [Gregory and Kendall].” Ex. 2021 ¶ 30. We agree with
Dr. Dershowitz that there is similarity between the Gregory and Kendall
toilets, such as having a bowl over a discharge valve, and a concentrated
central load. See Ex. 1027 ¶¶ 250–251. Patent Owner is essentially
repeating the contention that a person of ordinary skill in the art would find
no teachings in Kendall that are applicable to Gregory. As explained above,
such is not the case.
Third, Patent Owner contends that Petitioner’s reasoning that the
references each disclose concentrating the load centrally and have
IPR2014-01511
Patent 6,536,054 B2

36
detachable outer shrouds which do not bear weight is deficient. PO Resp.
31–32. In particular, Patent Owner asserts that Kendall removes all load
from the shell for the cosmetic reason of swapping the shell for another color
or texture, while Gregory stresses the impact resistance of toilet parts. Id.
According to Patent Owner these disclosures would have lead a person of
ordinary skill not to combine the references. Id. Patent Owner has not
considered the disclosure of Kendall as a whole in that Patent Owner does
not address Kendall’s disclosure that the removable shell “facilitates ease of
servicing the fixture.” See PO Resp. 31–32; Ex. 1013, 3:53–56. To the
extent that Patent Owner is arguing that Gregory and/or Kendall teach away
from the claimed subject matter, we disagree. Patent Owner has not
identified, nor do we discern any disclosure in the references that would
have lead a person of ordinary skill in a direction divergent from that
proposed by Petitioner. See In re Haruna, 249 F.3d 1327, 1335 (Fed. Cir.
2001) (“‘A reference may be said to teach away when a person of ordinary
skill, upon reading the reference, . . . would be led in a direction divergent
from the path that was taken by the applicant.’” (citation omitted)).
e) Secondary Considerations
Patent Owner contends that the nonobviousness of the claimed
methods is demonstrated by secondary considerations, namely, that the
claimed methods: (1) satisfied a long-felt and unmet need for improved
methods of servicing vacuum toilets, (2) received industry praise, and (3)
were commercially successful. PO Resp. 45–51.
Patent Owner essentially uses the same extrinsic evidence used in
IPR2014-01510 and IPR2014-01513 relating to LRUs and applies it here to f
toolless replacement of components.
IPR2014-01511
Patent 6,536,054 B2

37
(1) Satisfaction of Long-felt Need
Patent Owner contends that “[a]t the time of the invention of the ’054
Patent, vacuum toilets, particularly on aircraft, did not include a toilet bowl
that could be replaced in the field while the toilet assembly remained
installed.” PO Resp. 47 (citing Anderson Decl., Ex. 2021 ¶ 16; Jones Decl.,
Ex. 2022 ¶ 25–29). Patent Owner elaborates that in the prior art, the entire
toilet was treated as an LRU, meaning the entire toilet was uninstalled and
removed from the aircraft, removing the aircraft from revenue service. Id.
Patent Owner contends that the claimed methods “finally made it possible
for maintenance persons and airlines to service vacuum toilets without
requiring that the aircraft be removed from revenue service.” Id. at 47–48.
This evidence is deficient in at least two respects. First, it states only
that there was a need at the time of the invention. It does not allege, let
alone show, that an art recognized problem existed for a long period of time
without solution. See Newell Cos. v. Kenney Mfg. Co., 864 F. 2d 757, 768
(Fed. Cir. 1988).
Second, this evidence does not address the extent of the problem, or
attempts by others to solve the problem. See In re Allen, 324 F.2d 993, 997
(CCPA 1963) (an allegation of failure by others is not evidence of
nonobviousness unless it is shown that widespread efforts of skilled workers
having knowledge of the prior art had failed to find a solution to the
problem). We agree with Petitioner that Patent Owner “has not proven the
date when that supposed need first arose, how long it was felt, that the patent
met it, or that others tried but failed.” Pet. Reply 23.
Patent Owner’s argument also is unpersuasive because it lacks nexus
to the claimed subject matter in that the claims do not require that aircraft
IPR2014-01511
Patent 6,536,054 B2

38
remain in revenue service during replacement of an LRU. See Ashland Oil,
Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 305 n.42 (Fed. Cir.
1985), cert. denied, 475 U.S. 1017 (1986). In fact, claims 1 and 10 deal with
toolless replacement of components, and do not recite LRUs.
(2) Industry Praise
Patent Owner contends that praise specifically related to features of
the patented invention is probative of the nonobviousness of an invention.
PO Resp. 48–49 (citing Power-One, Inc. v. Artesyn Techs., Inc., 599 F.3d
1343, 1352 (Fed. Cir. 2010)). Patent Owner identifies two sources of such
praise: one, an April 2015 story on Skift, a travel and airline industry
website, and two, praise from Petitioner as a competitor.
The Skift article is titled, “The Airline Toilet That is Set to
Revolutionize In-Flight Relief.” Ex. 2025, 1. The article describes that
traditional toilets had to be replaced as an entire unit, and had a right or left
hand pipe version so that airlines had to stock both versions of the toilet. Id.
at 2. The Revolution toilet includes a number of interchangeable sub-
assembly parts, and a reversible pipe, permitting airlines to stock sub-
assemblies rather than entire toilets, and to quickly replace faulty parts. Id.
The article goes on to state that “[t]he very best part” of the Revolution toilet
is that the bowl is made of a new composite that is lighter and yet has the
lubricity of Teflon. Id. at 3.
Patent Owner states, but provides no evidence, that the Revolution
toilet is the toilet of the ’054 patent.26 See PO Resp. 46–47; In re Pearson,

26 The lack of such evidence makes that case at hand distinguishable from
PPC Broadband, Inc. v. Corning Optical Communications RF, LLC, No.
2015–1361, 2016 WL 692368, at *8 (Fed. Cir. Feb. 22, 2016).
IPR2014-01511
Patent 6,536,054 B2

39
494 F.2d 1399, 1405 (CCPA 1974) (attorney’s arguments do not take the
place of evidence); Pet. Reply 22 (noting this absence of proof). . The
article mentions quick maintenance, but does not mention that such
maintenance may be accomplished without tools. Other praise is clearly not
linked to claimed features, like the reversible pipe. Further, the article is
explicit that bowl composition, an unclaimed feature, is the very best part of
the toilet.
Patent Owner contends that Petitioner’s praise for the LRUs of the
’054 patent is further evidence that the claimed methods would not have
been obvious. PO Resp. 48–49 (citing the Meyers Decl., Ex. 202427 ¶¶ 16–
18). According to Patent Owner, the Meyers Declaration states that
Petitioner developed a vacuum toilet that includes modular LRU’s based on
the invention from Patent Owner and Patent Owner’s predecessor, Evac, and
therefore the praise for Petitioner’s toilets, is actually praise for the claimed
subject matter. Ex. 2024 ¶¶ 17–18 (citing Ex. 2020).
The portion of Exhibit 2020 cited by Mr. Meyers includes the
following statements:
2001-Envirovac Begins Development of Advanced Technology
toilet – E-max
2007-B/E [Petitioner] Enters Market; resurrects Advanced
Technology
See Ex. 2020, “BE-MAG-001-00103175,” also labeled “Page 3.” In this
context, Petitioner’s use of the phrase “Advanced Technology” seems to be

27 Exhibit 2024 includes two versions of the Meyers Declaration: redacted
and unredacted.
IPR2014-01511
Patent 6,536,054 B2

40
the name of the toilet rather than a comment that the technology of the toilet
is advanced.
Mr. Meyers’s citations to evidence that Petitioner praised Petitioner’s
toilets is unpersuasive because Patent Owner does not explain persuasively
any nexus to the claimed subject matter. In particular, none of the evidence
addresses toolless replacement of toilet components.
Patent Owner has not shown effectively that the praise specifically
relates to features of the patented invention and for that reason this evidence
has no effect on our obviousness analysis. See Power-One, 599 F.3d at
1352.
(3) Commercial Success
Patent Owner contends that the commercial success of the
Revolution™ toilet is further evidence of nonobviousness of the claimed
subject matter. PO Resp. 49–51 (citing In re Glatt Air Techniques, Inc., 630
F.3d 1026, 1030 (Fed. Cir. 2011)). Patent Owner provides evidence that 103
units were sold in 2014. Id. at 49. Mr. Conrad, Vice President of Sales,
Marketing and Customer support for Patent Owner, states that he has
personal knowledge of the sale of the 103 units. Ex. 2055 ¶¶ 1, 5. Patent
Owner also provides projections of sales, to include projections of market
share. PO Resp. 49–50. According to Mr. Conrad, “[s]ales of the
Revolution™ toilet are driven in large part by the very high reliability and
simplicity of maintenance of the toilet which is a function of the design and
how easily and quickly the modular components of the Revolution™ toilet
can be replaced ‘on wing.’” Ex. 2055 ¶ 7; PO Resp. 49. Patent Owner
provides evidence that Petitioner’s toilets that include the claimed toollessly
replaceable LRUs moved Petitioner’s market share for water and waste
IPR2014-01511
Patent 6,536,054 B2

41
systems from zero percent in 2008 to a projected four percent by the year
2020, growth that Mr. Conrad contends the aircraft supplier industry would
consider “astounding.” PO Resp. 50 (citing Ex. 2055 ¶ 8).
This evidence is unpersuasive for several reasons. First, Patent Owner
has not provided persuasive evidence of market share. Without market share
information, the 103 units sold in 2014 cannot be put in perspective. See In
re Applied Materials, Inc., 692 F.3d 1289, 1299 (Fed. Cir. 2012) (even the
number of units sold, without market share information, is only weak
evidence, if any, of commercial success). Projections of sales are only
estimates of future activity and do little or nothing to show the actual
commercial success of the claimed subject matter. Further, the projections
regarding sales of Petitioner’s toilets speak in terms of the “water and waste
systems market for commercial aircraft” and it is unclear what portion of
this market is attributable to vacuum toilets. See Ex. 2055 ¶ 9.
Second, Patent Owner’s evidence of sales of Petitioner’s toilets is
unpersuasive because Patent Owner provides no evidence that the
Revolution toilet embodies all of any of the challenged claims. See PO
Resp. 49–51.
Third, Patent Owner does not explain persuasively how the sales are
tied to claimed features. See PO Resp. 47–49; Ex. 2055 ¶¶ 1–10
(Mr. Conrad makes no mention of replacing components without tools).
Indeed, Patent Owner’s evidence attributes sales to unclaimed features (e.g.,
reliability, simplicity of maintenance, and the ease and speed modular
components may be replaced “on wing”). Ex. 2055 ¶ 7.
IPR2014-01511
Patent 6,536,054 B2

42
(4) Summary of Secondary Considerations
Patent Owner provides some evidence of a need at the time of
invention. However, this evidence falls short of demonstrating a long-felt
need because it does not address the length of the need, the extent of the
problem, or attempts by others to solve the problem. This evidence is
further undermined by the absence of a nexus to the claimed subject matter.
Patent Owner shows some praise for the Revolution toilet and praise by
Petitioner of Petitioner’s toilets, but this evidence is not persuasive because
of a lack of nexus to the claimed subject matter. Similarly, Patent Owner’s
evidence of commercial success does not demonstrate persuasively the
extent of Patent Owner’s market share, and is not tied to claimed features.
f) Conclusion for independent claims 1 and 10
We have considered the entirety of the evidence, including the
objective evidence of nonobviousness or secondary considerations. The
evidence of nonobviousness is weak and the evidence of obviousness is
strong. The entirety of the evidence weighs in favor of a conclusion of
obviousness. We conclude that Petitioner has demonstrated by a
preponderance of the evidence that claims 1 and 10 are unpatentable for
obviousness under 35 U.S.C. § 103(a) over Gregory and Kendall.
As mentioned in our analysis of Patent Owner’s Motion to Exclude
Evidence, a key factual basis of Patent Owner’s secondary considerations is
the contention that at the time of the invention of the ’054 patent, vacuum
toilets, particularly on aircraft, did not include a toilet bowl, rinse valve,
discharge valve, and/or FCU that could be replaced in the field while the
toilet assembly remained installed. See, e.g., PO Resp. 44–45.
IPR2014-01511
Patent 6,536,054 B2

43
Petitioner provides copies of Patent Owner’s Service Bulletins that
indicate that, prior to the time of the ’054 patent invention, it was possible to
remove and replace components of a vacuum toilet installed in an aircraft,
such as a rinse valve, without removing the toilet from the aircraft. See Ex.
1069 ¶ 92; Ex. 1061, 1–2. This evidence undermines the basis of Patent
Owner’s secondary considerations. We emphasize that even without
Petitioner’s evidence, Patent Owner’s secondary considerations did not alter
our conclusion of obviousness.
2. Claims 6 and 14
Claims 6 and 14 follow:

6. The assembly of claim 1, in which the vacuum waste system
further comprises a rinse valve and a rinse fluid pipe, and in
which the receptacle further comprises a rinse fluid dispenser
adapted for toollessly releasable attachment to the rinse fluid
pipe.
14. The method of claim 10, in which the vacuum waste system
further comprises a rinse valve and a rinse fluid pipe, and in
which each of the receptacle and new receptacle further
comprises a rinse fluid dispenser, the method further comprising
detaching the rinse fluid dispenser of the receptacle from the
rinse fluid pipe prior to the lifting step and attaching the rinse
fluid dispenser of the new receptacle to the rinse fluid pipe after
the inserting step.
Petitioner relies on Gregory for the additional limitations of claims 6
and 14. Pet. 37, 28–30; Ex. 1027 ¶¶ 218–220.
Patent Owner argues that “Gregory does not disclose a rinse valve,
rinse fluid pipe, or rinse fluid dispenser” as claimed because in Gregory
these components are integrated into Gregory’s spray ring. PO Resp. 18–19,
27; Ex. 2021 ¶¶ 21, 33; Ex. 1015, 2:1–7. Mr. Anderson states that Gregory’s
IPR2014-01511
Patent 6,536,054 B2

44
spray ring 12 integrates the pipe and rinse fluid dispenser and therefore,
these components are not toollessly replaceable.
Mr. Anderson cites a portion of Gregory describing that water valve
18 directs water to spray ring 12. See Ex. 2021 ¶¶ 21, 33 (citing Ex. 1015,
3:49–52). This disclosure provides no support for Mr. Anderson’s opinion
that Gregory’s components are integrated, nor does Mr. Anderson provide
any other underlying facts or data for this opinion.
Gregory explicitly states that spray ring 12 includes shoulder 46 that
is adapted to be seated on the shoulder formed by rim wall flange 30, and
may be “releasably snapped into place.” Ex. 1015, 5:54–58; see also 2:1–7
(describing that the toilet includes a “detachably mounted flushing water
spray ring”); Pet. 28–30; Ex. 1027 ¶¶ 218–220 (citing these portions of
Gregory, providing an annotated version of Gregory’s Figure 3, and
explaining that spray ring 12 is toollessly releasable from hose 228).
On this record, we conclude that Petitioner has demonstrated by a
preponderance of the evidence that claims 6 and 14 are unpatentable for
obviousness under 35 U.S.C. § 103(a) over Gregory and Kendall.
3. Claims 7 and 15
Claims 7 and 15 follow:
7. The assembly of claim 1, in which the receptacle is made of a
plastic material.
15. The method of claim 10, in which the receptacle is made of
a plastic material.
Patent Owner argues that Gregory does not disclose a plastic waste
receptacle as required by claims 7 and 15; rather, according to Patent Owner,
Gregory discloses a heavy metal bowl and emphasizes the need for a heavy
sturdy bowl. PO Resp. 19–20. Patent Owner contends that Kendall does not
IPR2014-01511
Patent 6,536,054 B2

45
disclose a plastic bowl; rather, Kendall discloses a metal or ceramic bowl.
Id. at 28–29.
Patent Owner’s contention regarding Gregory is not responsive to
Petitioner’s position because Petitioner relies upon Kendall’s inner shell 1 as
corresponding to a waste receptacle as claimed because it may be formed of
any suitable material, including plastics. Pet. 38 (citing Ex. 1013, 1:11–16;
Ex. 1027 ¶ 291). Patent Owner does not address persuasively this
contention. We agree with Petitioner that Kendall’s inner shell 1 is
preferably made of a suitable plastic material. Pet. Reply 16 (citing Ex.
1013, 5:10, 3:65–68); see also Anderson Depo., Ex. 1052, 45:8–12
(identifying Kendall’s “item 1” (shell 1) as the toilet bowl (waste
receptacle)).
On this record, we conclude that Petitioner has demonstrated by a
preponderance of the evidence that claims 7 and 15 are unpatentable for
obviousness under 35 U.S.C. § 103(a) over Gregory and Kendall.
4. Claims 4, 5, 9, 12, 13, and 1728
Claims 4, 5, 9, 12, 13, and 17 follow.
4. The assembly of claim 1, in which the top member of the
frame further defines the receptacle engaging portion.
5. The assembly of claim 4, in which the receptacle includes a
flange defining the abutting portion of the receptacle.
9. The assembly of claim 1, in which the receptacle is formed as
a toilet bowl.
12. The method of claim 10, in which the top member of the
frame further defines the receptacle engaging portion.

28 Patent Owner provides no additional arguments for the dependent claims
and therefore has admitted the material facts of this ground unpatentability
for these claims. See 37 C.F.R. §§ 42.23(a), 42.120(a).
IPR2014-01511
Patent 6,536,054 B2

46
13. The method of claim 12, in which the each of the receptacle
and new receptacle includes a flange defining the abutting
portion.
17. The method of claim 10, in which the receptacle is formed
as a toilet bowl.
As analyzed above, the proposed combination includes a top member
of the frame that defines the receptacle engaging portion (Kendall’s pins 33A
or attachment bolts of top section 33), and the receptacle (Gregory’s basin
1), which is formed as a toilet bowl, includes a flange (Kendall’s flange 3)
defining the abutting portion of the receptacle. See Pet. 37.
On this record, we conclude that Petitioner has demonstrated by a
preponderance of the evidence that claims 4, 5, 9, 12, 13, and 17 are
unpatentable for obviousness under 35 U.S.C. § 103(a) over Gregory and
Kendall.

C. STEWART, GROOMBRIDGE, AND GREGORY
Petitioner contends that Stewart discloses a toilet for use in a
recreational vehicle that includes upper housing part 22 that contains a waste
receptacle (toilet bowl 26) attached by adhesive to lower housing part 24.
Pet. 45, 38˗39. Petitioner contends that given Stewart’s emphasis on easy
maintenance, it would have been obvious to make the upper housing
removable by replacing Stewart’s adhesive with snap coupling, as taught by
Groombridge. Pet. 39˗40. Petitioner reasons that Stewart and Groombridge
teach similar designs of similar materials (plastic). Id. at 40–41 (citing Ex.
1018, 4:24–25, 11:62–65; Ex. 1019, 2:46–48, 3:65–68; Ex. 1027 ¶¶ 313–
317). Petitioner contends that it would have been obvious to replace
Stewart’s swing drop valve with a discharge valve and vacuum system as
IPR2014-01511
Patent 6,536,054 B2

47
disclosed by Gregory, to create a vacuum toilet system for use in a
recreational or transport vehicle. Pet. 45˗46 (citing Ex. 1015, 1:35–37; Ex.
1027 ¶ 345). Petitioner reasons that Stewart and Gregory are of similar
construction, and that the modification creates a device ideal for use in
recreational vehicles or other transport vehicles. Id. at 46 (citing Ex. 1015,
1:35–37; Ex. 1027 ¶ 345).
Petitioner contends that “given Stewart’s emphasis on easy
maintenance, it would have been obvious to make the upper housing
(including the bowl) removable, in light of, e.g., Groombridge.” Pet. 39–40,
45. We examine this contention with regard to each reference.
Petitioner does not cite to any portion of Stewart demonstrating an
emphasis on ease of maintenance. See Pet. 9–10, 38–43; 37 C.F.R.
§ 42.104(b)(5) (the petition must identify specific portions of the evidence
supporting the challenge and the Board may exclude or give no weight to
evidence not so identified). Nor does Petitioner cite to other supporting
evidence.
Petitioner contends that Groombridge discloses making the upper
housing removable because Groombridge’s snap couplings are manually
detachable fastening means. Pet. 10, 39–40, 43, 45 (citing Ex. 1019, 2:46–
48, 3:65–68; Ex. 1027 ¶¶ 313–317). In order to support Petitioner’s ground
of unpatentability, Groombridge’s snap couplings must be releasable without
tools. Petitioner does not identify, nor does Groombridge explicitly disclose,
that the upper housing is removable or that the snap couplings are toollessly
detachable.
Groombridge’s water closet 10 includes cistern 14 connected to basin
12. Ex. 1019, 2:46–48, 3:65–68. Regarding this connection, Groombridge
IPR2014-01511
Patent 6,536,054 B2

48
describes that “any suitable form of attachment may be employed, such as
snap couplings, adhesives, etc., which are employed with appropriate seals,”
and a welded connection is preferred. Id. at 3:65–4:2. In this context, snap
couplings are listed with adhesives, suggesting a permanent rather than
releasable connection. The cited portion of the Dershowitz Declaration cites
to the same portion of Groombridge and adds nothing to the analysis in the
Petition. See Pet. 45 (citing Ex. 1027 ¶¶ 313–317, in particular ¶ 315 citing
Ex. 1019, 3:65–68).
Petitioner contends that a person of ordinary skill in the art would
know that connections containing fluid must be sealed and would design a
product accordingly. Pet. Reply 19 (citing Ex. 1068 ¶ 109). However, the
issue is not whether Groombridge’s snap coupling would provide a fluid
seal, the issue is whether the couplings are toollessly releasable.
Petitioner refers to Groombridge’s snap couplings as “[t]oolless snap
couplings.” Pet. 19 (citing Ex. 1019, 3:65–68; Ex. 1052, 86:7–20;29 Ex.
1053, 151:20–22; Ex. 1068 ¶ 109). These citations do not support
characterizing Groombridge’s snap couplings as releasable without tools.
First, as explained above, Groombridge does not explicitly describe the snap
couplings as toolless, and the context of the disclosure is at least equally
suggestive that the couplings are not releasable. Second, Mr. Anderson
testified that he does not think tools are required to snap the two components
into place, but the issue is separating the components without tools, not
connecting them. See Ex. 1052, 86:7–20. The testimony of Mr. Jones dealt
with snap couplings in general and not Groombridge’s snap couplings. See

29 Petitioner cites Exhibit 1050, but based on content appears to intend to
refer to Exhibit 1052.

Ex. 1053, 150:9–152:11. Such testimony sheds little or no light on the issue
before us. Fourth, Dr. Dershowitz opines that Groombridge’s snap
couplings would provide a seal. See Ex. 1068 ¶ 109. The issue is not
whether the couplings provide a seal, but whether the couplings may be
toollessly released.
Petitioner has not demonstrated by a preponderance of the evidence
that the combination of Stewart and Groombridge creates a waste receptacle
that may be toollessly removed from the installed position independent of
the frame as required by claim 1 and 10. The same reasons that highlight the
absence of this limitation also undermine Petitioner’s proffered reason for
combing the references of creating a detachable waste receptacle. See KSR,
550 U.S. at 418 (making clear that “rejections on obviousness grounds
cannot be sustained by mere conclusory statements; instead, there must be
some articulated reasoning with some rational underpinning to support the
legal conclusion of obviousness.” (citation omitted)).
On this record, we conclude that Petitioner has not demonstrated by a
preponderance of the evidence that claims 1 and 10 are unpatentable for
obviousness under 35 U.S.C. § 103(a) over Stewart, Groombridge and
Gregory. Claims 4–7, 9, 12–15, and 17 depend from independent claims 1
and 10 and consequently the ground of unpatentability for these claims is
deficient as well.

V. MOTIONS TO SEAL
Patent Owner filed two Motions to Seal (Papers 40 and 87), and
Petitioner also a Motion to Seal (Paper 66). There is a strong public policy
in favor of making information filed in an inter partes review open to the
IPR2014-01511
Patent 6,536,054 B2

50
public, especially because the proceeding determines the patentability of
claims in an issued patent and, therefore, affects the rights of the public. See
Garmin International v. Garmin Speed Technologies, LLC, Case IPR2012-
00001 (PTAB Mar. 14, 2013) (Paper 34). Under 35 U.S.C. § 316(a)(1) and
37 C.F.R. § 42.14, the default rule is that all papers filed in an inter partes
review are open and available for access by the public; a party, however,
may file a concurrent motion to seal and the information at issue is sealed
pending the outcome of the motion. It is, however, only “confidential
information” that is protected from disclosure. 35 U.S.C. § 316(a)(7); see
Trial Practice Guide, 77 Fed. Reg. at 48,760. The standard for granting a
motion to seal is “for good cause.” 37 C.F.R. § 42.54(a). The party moving
to seal bears the burden of proof in showing entitlement to the requested
relief, and must explain why the information sought to be sealed constitutes
confidential information. 37 C.F.R. § 42.20(c).
In reviewing the underlying documents that are sought to be sealed,
we conclude that they may contain confidential information. Accordingly,
we are persuaded that good cause exists to have some of the documents
remain under seal. In that respect, the Motions to Seal (Papers 40, 66, 87)
are granted, except for information that is discussed in or relied on by this
decision. With regard to such information, pertinent to substantive
patentability analysis leading to the determination that claims 1, 4–7, 9, 10,
12–15, and 17 are unpatentable, we discern no reason to shield them from
the public. The parties have shown no good cause to seal such information.
The Office Patent Trial Practice Guide provides:
Expungement of Confidential Information: Confidential
information that is subject to a protective order ordinarily would
become public 45 days after denial of a petition to institute a trial

Patent 6,536,054 B2

51
or 45 days after final judgment in a trial. There is an expectation
that information will be made public where the existence of the
information is referred to in a decision to grant or deny a request
to institute a review or is identified in a final written decision
following a trial. A party seeking to maintain the confidentiality
of information, however, may file a motion to expunge the
information from the record prior to the information becoming
public. § 42.56. The rule balances the needs of the parties to
submit confidential information with the public interest in
maintaining a complete and understandable file history for public
notice purposes. The rule encourages parties to redact sensitive
information, where possible, rather than seeking to seal entire
documents.
77 Fed. Reg. 48756, 48766 (Aug. 14, 2012).
Consequently, 45 days from entry of this decision, all information
subject to a protective order will be made public by default. In the interim, a
party seeking to maintain confidentiality of information that was not relied
upon in this decision, may file a motion to expunge that information. See 37
C.F.R. § 42.56.

VI. ORDER
For the reasons given, it is:
ORDERED that claims 1, 4–7, 9, 10, 12–15, and 17 of U.S. Patent
No. 6,536,054 B2 have been shown by a preponderance of the evidence to
be unpatentable over Gregory and Kendall;
FURTHER ORDERED that Patent Owner’s Motion to Exclude is
denied;
FURTHER ORDERED that Petitioner’s Motion to Exclude is denied;
FURTHER ORDER that the Motions to Seal are granted-in-part and
denied-in-part as noted herein; and
IPR2014-01511
Patent 6,536,054 B2

52
FURTHER ORDERED that, because this is a Final Written Decision,
parties to the proceeding seeking judicial review of the decision must
comply with the notice and service requirements of 37 C.F.R. § 90.2.
