I. INTRODUCTION
2

Petitioner, RPX Corporation (“RPX”), filed Petitions in the above-
listed cases. Patent Owner, Virnetx Inc. (“Virnetx”), submitted Preliminary
Responses. Because the dispositive issues are similar, we treat IPR2014-
00171 (“the ’171 proceeding”) as representative of the seven proceedings,
which involve four Virnetx patents: U.S. Patent No. 6,502,135; U.S. Patent
No. 7,490,151; U.S. Patent No. 7,921,211; and U.S. Patent No. 7,418,504
(“the Virnetx Patents”).
The seven proceedings involving the Virnetx Patents, challenged
under 35 U.S.C. §§ 311–319, are summarized in the following table:
Proceeding Claims Virnetx
Patents
IPR2014-00171 1–10, 12–15, and 18 6,502,135
IPR2014-00172 1–10, 12–15, and 18 6,502,135
IPR2014-00173 1–16 7,490,151
IPR2014-00174 1, 2, 5, 6, 8, 14, 17, 19, 20, 23, 27–30, 33,
34, 36, 47, 51, and 60
7,921,211
IPR2014-00175 1, 3, 15–18, 20–26, 31, 32, 35, 36, 37, 47,
51, and 60
7,921,211
IPR2014-00176 1, 2, 5, 6, 8, 14, 16, 17, 19, 20, 21, 23,
27–30, 33, 34, 36, 47, 51, and 60
7,418,504
IPR2014-00177 1, 2, 3, 5, 15–18, 20–27, 31, 32, 35, 36,
47, 51, and 60
7,418,504

As the table reflects, in the ’171 proceeding, RPX filed a Petition
requesting inter partes review of claims 1–10, 12–15, and 18 of U.S. Patent

No. 6,502,135 (“the ’135 Patent”). See Paper 1 (“Pet.”).

Virnetx submitted
a Preliminary Response under 37 C.F.R. § 42.107(b). Paper 35 (“Prelim.
Resp.”).
We have jurisdiction under 35 U.S.C. § 314. We determine that
Apple Inc. (“Apple”) is a real-party-in interest.
4
We deny the Petitions
because the Petitions are time-barred. Contrary to the requirements of 35
U.S.C. § 315(b), the Petitions were “filed more than 1 year after the date on
which the . . . real party in interest[, Apple,] . . . [wa]s served with a
complaint alleging infringement of the patent.” Therefore, according to 35
U.S.C. § 315(b), “[a]n inter partes review may not be instituted.”
For an analysis of the time bar issue pursuant to 35 U.S.C. § 315(b),
we refer to, and incorporate by reference, the Board’s previous decisions
holding that earlier petitions filed by Apple, a real party-in-interest in those
proceedings challenging the Virnetx Patents, were time-barred.
5
As Apple is
a real party-in-interest in the instant proceedings, the Petitions are time-

Record citations refer to the representative ’171 proceeding.
4
The Petitions do not list Apple, as 35 U.S.C. § 312(a)(2) requires: “A
petition filed under section 311 may be considered only if . . . the petition
identifies all real parties in interest.”

cases, the decisions were entered on December 18, 2013, although the
rehearing decisions were entered on the same date in all the cases, February
12, 2014.

barred for the same reasons as previously held. See Prelim. Resp. 3–4
(discussing time-bar).
II. BACKGROUND
At issue here is whether RPX, notwithstanding its relationship with its
client Apple, may obtain inter partes review of the Virnetx Patents. Virnetx
asserts, and RPX does not dispute, that RPX filed inter partes review
(“IPR”) requests against the Virnetx Patents pursuant to a newly created
program in which Apple, as RPX’s client, in October 2013, paid RPX a sum
of $500,000, among other things, to file IPR reviews. See Prelim. Resp. 3–
4; Ex. 2049 (Premium Services Overview); Ex. 2055 (signed “Addendum”
agreement between Apple and RPX, Oct. 22, 2013).
In addition to RPX and Apple, another petitioner also filed a series of
inter partes review petitions against the Virnetx Patents, which Apple
attempted to join. Those proceedings were styled as New Bay Capital v.
Virnetx (“the New Bay proceedings”): IPR2013-00375; IPR2013-00376;
IPR2013-00377; and IPR2013-00378. Pursuant to New Bay’s request, the
Board terminated the New Bay proceedings, and according to Virnetx,
“end[ed] Apple’s hopes of joining New Bay’s petitions.” See Prelim. Resp.
4; Ex. 2036 (discussing Apple’s motion for joinder in New Bay cases); Ex.
2037 (New Bay email to office requesting to file motion to terminate); Exs.
2039–42 (judgments terminating the New Bay proceedings).
Prior and subsequent to the New Bay proceedings, RPX and Apple
had discussed a general proposal “to challenge patents of questionable
quality through post-grant proceedings at the U.S. Patent and Trademark
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

Office.” Ex. 2043, 15. According to RPX, the following “Topic” of
discussion between Apple and RPX occurred on August 8, 2013:
Apple informed RPX that Apple had been approached by
New Bay Capital (“NBC”) and that NBC had asked Apple to
compensate NBC for NBC to continue pursuing its IPRs [now
terminated] against VirnetX. Apple informed RPX that it was
not interested in NBC’s offer. Apple inquired [of RPX] about
the status of the previously-socialized RPX program to perform
prior art searches and challenge patents of questionable quality.
Ex. 2043, 15 (“August 8
th
discussion”).
Subsequent to the August 8
th
discussion about the Virnetx Patents,
Apple and RPX signed the “Addendum” agreement, pursuant to which
Apple paid RPX $500,000, among other things, to “fil[e] with the United
States Patent and Trademark Office (‘USPTO’) requests for reexamination,
or petitions for post grant, covered business method, or inter partes review
with respect to patents of questionable quality.” Ex. 2055, 2 (Addendum
agreement). The Addendum agreement lists other generic activities that
RPX might perform. See id. (“analyzing data . . . [about] patent assertions
by non-practicing entities,” “[e]ducating the general public,” “[c]onducting
prior art searches to assist with challenges against potentially invalid
patents,” and “[c]reating mechanisms to increase transparency in the patent
market).” The addendum states that RPX would have “complete control”
over the listed activities. Id.
Apple and RPX executed the Addendum agreement on October 22,
2013. Id. at 3. On the same day, Apple expressed a concern that RPX
“would not use all of the funds that Apple contributed to the program
focused on patent quality.” Ex. 2043, 16. One day prior, RPX obtained
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

Apple’s consent to hire Apple’s law firm, which had prepared the above-
discussed time-barred petitions on behalf of Apple. See Paper 38, 4–5
(citing Ex. 2045 at 5, retainer agreement); Prelim. Resp. 6–7 (discussing the
sharing of counsel); Ex. 2057, 27:6–28:18–21 (transcript of Board
conference call).
Less than one month later, RPX served the instant Petitions on
Virnetx challenging the Virnetx Patents. According to RPX, in the ’171
proceeding, “[t]he grounds of Petitioner’s challenge are substantially
identical to the grounds advanced by [Apple or New Bay] in IPR2013-
00348, IPR2013-00349, and IPR2013-00375”––the former two proceedings
involve Apple’s time-barred petitions. See Pet. 6.

III. ANALYSIS
The Office Patent Trial Practice Guide, 77 Fed. Reg. 48,756, 48,759–
60 (Aug. 14, 2012) (“TPG”) cites Taylor v. Sturgell, 553 U.S. 880 (2008), as
informing real party-in-interest determinations. Taylor, 553 U.S. at 893–
895, lists six categories that create an exception to the common law rule that
normally forbids nonparty preclusion in litigation. Id. Under a category
relevant here, “a party bound by a judgment may not avoid its preclusive
force by relitigating through a proxy.” Id. at 895. Taylor refers to a proxy
as a “representative or agent of a party who is bound by the prior
adjudication.” Id. at 905. For further guidance, the TPG also cites In re

According to RPX, the ’171 Petition is “substantially identical” to the
petition in IPR2013-00349, the petition filed by Apple with respect to one
prior art reference. For example, the ’171 Petition (Paper 1, ii) and the
petition in IPR2013-00349 (paper 1, ii) each assert that Aventail anticipates
claims 1-10, 12-15, and 18 of the ’135 Patent.
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

Guan, Reexamination Control No. 95/001,045 (Aug. 25, 2008)(Decision
Vacating Filing Date). TPG at 48,761. Apple is bound by the prior time-
barred district court adjudications. Thus, because RPX is Apple’s proxy, the
RPX Petition is also time-barred.
In Guan, a “Troll Busters” website invited prospective patent
challengers to “[p]ick any five Affymetrix or Symyx U.S. patents and Troll
Busters will invalidate a sixth for free.” Guan at 2. The Office held that
[a]n entity named as the sole real party in interest may not
receive a suggestion from another party that a particular patent
should be the subject of a request for inter partes reexamination
and be compensated by that party for the filing of the request
for inter partes reexamination of that patent without naming the
party [as a real party-in-interest] who suggested and
compensated the entity for the filing of a request for inter partes
reexamination of the patent.
Id. at 7–8 (emphasis added). Based on the failure to list such a real party-in-
interest, the Office vacated the filing date of the reexamination request. Id.
at 9.
Like the unnamed real party-in-interest in Guan, Apple at least
suggested that RPX file challenges to the specific Virnetx Patents by
compensating RPX to perform certain generic services that included filing
IPR challenges to “patents of questionable quality.” Ex. 2043, 15; Ex. 2055,
2. The record shows that Apple and RPX considered the Virnetx Patents to
be patents of questionable quality. See Ex. 2043, 15; Background section,
above. Further, RPX does not dispute that Apple and RPX discussed
“VirnetX and the filing of IPRs with RPX,” or that RPX and Apple shared
counsel and Apple’s expert. Paper 46, 7.
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

8

Other important factors also support the conclusion that Apple is a
real party-in-interest. For example, as Virnetx contends, General Foods
Corp. v. Massachusetts Department of Public Health, 648 F.2d 784, 788 (1st
Cir. 1981), instructs that “a member of a trade association who finances an
action which it brings on behalf of its members impliedly authorizes the
trade association to represent him in that action.” Paper 38, 5. Several
factors support a finding that Apple implicitly authorized RPX to represent
Apple in the instant proceedings: Apple’s $500,000 payment to RPX; the
discussions and signed agreement between Apple and RPX regarding the
filing of IPRs on patents of questionable quality; Apple and RPX’s “August
8
th
discussion” about New Bay’s request for funding to continue its IPR
challenges against the Virnetx Patents combined with Apple’s interest in
funding a program to challenge patents of questionable quality; and Apple’s
demonstrated interest in challenging the Virnetx Patents.
These factors are analogous to those that supported a finding of real-
party-in-interest in General Foods, including payments by association
members to instigate litigation, implicit authorization for the trade
association to represent the paying member, and “challenged regulations
[that] did not affect the trade association itself but only its members.” See
648 F.2d at 787–788; see also Expert Electric, Inc. v. Levine, 554 F.2d 1227,
1233 (2nd Cir. 1977) (trade association’s interests “were the collective
interests of the individual participants”). By further analogy, Apple was the
single, interested “member” of the Fund, unlike the numerous interested
trade association members in General Foods. See Ex. 2056 (RPX seeking
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

9

Apple’s permission to report Apple’s status as a “member” (Ex. 2043) for
client recruitment purposes).
RPX argues a distinction over General Foods, wherein the trade
association asserted standing based on its independent members. Here, RPX
asserts independent standing through § 311(a), which confers standing on
any entity that is not the patent owner. Paper 46, 4. In General Foods,
however, standing was only one of several factors identified by the court that
helped to show that the members implicitly authorized the suit by the
association. See 648 F.2d at 787–788. We hold that, based on the record
presented, the interactions between RPX and Apple show an implicit
authorization to challenge the Virnetx Patents, even in the absence of the
standing factor that contributed to the outcome in General Foods.
Apple’s interests include potentially avoiding payment of the damages
awarded for infringement of the Virnetx Patents in the district court
judgment. See Prelim. Resp. 3–4; Ex. 2009. On this record, RPX is, at
most, a “nominal plaintiff” with “no substantial interest” in these IPR
challenges apart from those of its client, Apple, further supporting the
finding that RPX is a proxy of Apple, according to the following case cited
by Taylor.
[W]e held [in a previous case] that the United States was bound
by an estoppel which might have been invoked against the real
party in interest if the suit had been brought in his name,
because it appeared that the United States had no substantial
interest in the controversy, and was merely a nominal plaintiff.
United States v. Des Moines Valley R. Co., 84 F. 40, 44–45 (8th Cir. 1897)
(emphasis added), cited in Taylor, 553 U.S. at 900 (in the context of a
IPR2014-00171 (Patent 6,502,135); IPR2014-00172 (Patent 6,502,135);
IPR2014-00173 (Patent 7,490,151); IPR2014-00174 (Patent 7,921,211);
IPR2014-00175 (Patent 7,921,211); IPR2014-00176 (Patent 7,418,504);
IPR2014-00177 (Patent 7,418,504)

proxy); see also Chicago R.I. & P. Ry. Co. v. Schendel, 270 U.S. 611, 620
(1926) (“Identity of parties is not a mere matter of form, but of substance.
Parties nominally the same may be, in legal effect, different; and parties
nominally different may be, in legal effect, the same.”)
Our determination that RPX is acting as a proxy, which bars the
institution of the proceeding, is also consistent with the express legislative
intent concerning the need for quiet title. See 157 Cong. Rec. S1034, S1041
(Mar. 1, 2011) (Sen. Kyl) (stating “the present bill does coordinate inter
partes . . . review with litigation . . . setting a time limit for seeking . . .
review if the petitioner . . . is sued for infringement of the patent”).
Congress “recognizes the importance of quiet title to patent owners to ensure
continued investment resources.” H.R. Rept. No 112-98, at 48 (2011)
(Judiciary Committee Report on H.R. 1249, June 1, 2011). Changes to the
statutory structure “are not to be used as tools for harassment or a means to
prevent market entry through repeated litigation and administrative attacks .
. . . Doing so would frustrate the purpose of the section as providing quick
and cost effective alternatives to litigation.” Id. “It would divert resources
from the research and development of inventions.” Id.
IV. CONCLUSION
Based on the foregoing discussion, Apple is an unlisted real party-in
interest in the Petitions, which are time-barred under 35 U.S.C. § 315 (b).
Accordingly, the following Petitions hereby are denied: IPR2014-00171
(Patent 6,502,135); IPR2014-00172 (Patent 6,502,135); IPR2014-00173
