PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE ____________ BEFORE THE PATENT TRIAL AND APPEAL BOARD ____________ KAISER ALUMINUM & CHEMICAL CORP., and CONSTELLIUM FRANCE1 Requesters v. Patent of ALCOA, INC. Patent Owner and Appellant ____________ Appeal 2016-008385 Reexamination Control Nos. 95/000,285 & 95/001,085 Patent 7,097,719 Technology Center 3900 ____________ Before ROMULO H. DELMENDO, RICHARD M. LEBOVITZ, and JEFFREY B. ROBERTSON, Administrative Patent Judges. ROBERTSON, Administrative Patent Judge. DECISION UNDER 37 C.F.R. § 41.77(f) 1 Formerly Alcan Rhenalu. (See Respondent Brief of Requester II, Constellium France, filed September 14, 2012, 1.) Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 2 This is a decision under 37 C.F.R. § 41.77(f). In the decision mailed October 9, 2015 (Appeal No. 2014-008138, “Decision on Appeal on Appeal” or “DOA”), we set forth the following new grounds of rejection pursuant to 37 C.F.R. § 41.77(b): Claims 1-6 and 8 under 35 U.S.C. § 112, second paragraph, because, contrary to the Examiner’s position, one of ordinary skill in the art would not be able to determine whether an alloy product would meet the average fatigue failure resistance recited in claims 1 and 3 (DOA 17-19, 21); and Claims 1-6 and 8 under 35 U.S.C. § 112, first paragraph as lacking written description as found by the Examiner, but denominated as a new ground of rejection because the rationale in the Decision on Appeal differed from the Examiner’s rationale. (DOA, 14-17.) Also in the Decision on Appeal, we affirmed the Examiner’s rejection of claims 1-6 and 8 under 35 U.S.C. § 112, first paragraph as lacking enablement. (DOA, 7-14, 20.) As a result of the new ground of rejection under 35 U.S.C. § 112, second paragraph, we reversed pro forma, the prior art rejections of claims 1-6 and 8. (DOA 20-21.) We also summarily affirmed the Examiner’s rejection of claim 14 over prior art because the rejection was no longer being contested. (DOA 2, FN4, 20.) In response to the Decision on Appeal, Patent Owner exercised its option under 37 C.F.R. § 41.77(b)(1) to file a request to reopen prosecution, proposing amendments to independent claims 1 and 3, and dependent claims 5, 6, and 8 subject to the new ground of rejection, and cancelling claim 14. (Patent Owner’s Amendment and Response, and Request to Reopen Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 3 Prosecution Under 37 C.F.R. § 41.77, filed October 22, 2015, hereinafter “PO 41.77(b)(1) Resp.” or “Request to Reopen”.) Third Party Requester Constellium France (Requester II) filed “COMMENTS OF REQUESTER II” on November 18, 2015 (hereinafter “Requester II’s Comments” or “Req. Comm.”) under 37 C.F.R. § 41.77(c) in response to the Patent Owner's Request to Reopen.2 An order granting Patent Owner’s request to reopen and remand the inter partes reexamination to the Examiner was issued. (“ORDER REMANDING INTER PARTES REEXAMINATION UNDER 37 C.F.R. § 41.77(d) to the EXAMINER”, hereinafter “Remand Order” mailed January 11, 2016.) An Examiner’s Determination under 37 C.F.R. § 41.77(d) was issued on March 3, 2016. (Hereinafter, “Ex. Det.”) In the Examiner’s Determination, the Examiner determined that the rejection under 35 U.S.C. § 112, second paragraph has been overcome with respect to claims 3 and 4, because the claims have been amended to no longer require a fatigue failure resistance value, but that the amendment to claim 1 was insufficient to overcome the rejection of claims 1, 2, 5, 6, and 8. (Ex. Det. 6-8.) Despite indicating that the rejection under 35 U.S.C. § 112, second paragraph had been overcome, the Examiner did not comment on the status of claims 3 and 4 as amended with respect to the prior art. (See generally Ex. Det.) The Examiner also determined that the rejection of claims 3 and 4 under 35 U.S.C. § 112, first paragraph as lacking written description had 2 Requester I, Kaiser Aluminum & Chemical Corp. did not file any papers under 37 C.F.R. § 41.77(c) or (e). Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 4 been overcome, but that the amendment to claim 1 was insufficient to overcome the rejection of claims 1, 2, 5, 6, and 8 for lack of written description. (Ex. Det. 5-6.) Both Patent Owner and Requester II filed responses to the Examiner’s Determination on April 1, 2016. (Comments on Examiner’s 41.77(d) Determination Under 37 C.F.R. § 41.77(e); Comments of Requester II Under 37 CFR 41.77(e).) In addition, both Patent Owner and Requester II filed responses to each other’s response to the Examiner’s Determination. (Response to Comments of Requester II Under 37 C.F.R. § 41.77(e) filed April 29, 2016; Reply of Requester II To Patent Owner’s Comments filed May 2, 2016.) Requester II’s response to the Examiner’s Determination was entered, but all other papers under 37 C.F.R. § 41.77(e) filed by Patent Owner and Requester were denied entry. (See Miscellaneous Communication to Applicant mailed July 28, 2016; Decision on Petition Under 37 C.F.R. § 1.181 mailed November 3, 2016.) Accordingly, out of all the responses filed under 37 C.F.R. § 41.77(e), only the Comments of Requester II Under 37 CFR 41.77(e) (“Req. II 41.77(e) Comments”) have been considered in rendering this decision. Pursuant to 37 C.F.R. § 41.77(f), this decision is deemed to incorporate our earlier decisions, except as indicated herein. CLAIM AMENDMENTS Independent claims 1 and 3, as amended with Patent Owner’s Request to Reopen, are reproduced below (with underlining showing additions to the Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 5 claims, bracketing showing deletions to the claims relative to the originally issued claims, and relevant changes reflecting the current amendment relative to previous amendments shown in bold font and double bracketing): 1. An improved aluminum alloy product having improved fatigue failure resistance, the aluminum alloy product consisting essentially of [about,] by weight, 7.6 to [about] 8.4% zinc, [about] 2.0 to [about] 2.5% copper, [about] 1.8 to [about] 2.3% magnesium, [about] 0.088 to [about] 0.25% zirconium, the balance to 100 weight % [substantially] aluminum and incidental elements and impurities, the improvement comprising maintaining the weight percents of iron and silicon to [about] 0.01 to not greater than 0.039 [[0.044]] [[[about]] 0.09%]3 iron, and [about] 0.01 to not greater than 0.029% [[[about]] 0.06%] silicon; wherein the aluminum alloy product contains from 7.83 to 8.08% zinc; wherein the aluminum alloy product contains from 2.10 to 2.17% copper; wherein the aluminum alloy product contains from 1.88 to 1.93% magnesium; wherein the aluminum alloy product contains from 0.11 to 0.13% zirconium; wherein the aluminum alloy product is absent of magnesium silicide (Mg2Si) intermetallic particles; wherein the improved fatigue failure resistance is that the aluminum alloy product achieves a log average fatigue life of at least [[about]] 355485 cycles, wherein the log average fatigue life is calculated based on at least 16 specimens from at least 4 lots, wherein each specimen is tested at a net section stress of 207 MPa using a Kt=2.5 open hole specimen having a length of 230 mm, a width of 25.4 mm, a thickness of 3.17 mm and two 3 As a formal matter, we observe that Patent Owner appears to have inadvertently deleted the “%” from the iron content. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 6 holes of 4.75 mm diameter spaced 25.4 mm apart, tested in ambient laboratory air, at a stress ratio of R=0.1 and a frequency of 25 Hz. 3. An improved AA 7XXX series aluminum alloy product suitable for aerospace applications having improved fatigue failure resistance[, said alloy comprising about, by weight, 7.6 to about 8.4% zinc, about 2.0 to about 2.6% copper, about 1.8 to about 2.3% magnesium, about 0.088 to about 0.25% Zr the balance to weight % substantially aluminum and incidental elements and impurities], the improvement comprising lowering the amount of Fe to [about] 0.01 to [[[about]] 0.09%]0.039 [[0.044]] wt. %, and the amount of Si to [about] 0.01 to [[[about]] 0.06%]0.029% wt. % in an AA 7XXX series aluminum alloy product consisting essentially of, by weight, from 7.83 to 8.08% zinc, from 2.10 to 2.17% copper, from 1.88 to 1.93% magnesium, from 0.11 to 0.13% zirconium, the balance to 100 weight % aluminum and incidental elements and impurities, wherein the AA 7XXX series aluminum alloy product is absent of magnesium silicide (Mg2Si) intermetallic particles [[wherein the improved fatigue failure resistance is that the AA 7XXX series alloy product achieves an average fatigue life of at least about 355485 cycles, based on the log average, at a net section stress of 207 MPa, wherein the fatigue life is measured using a Kt=2.5 open hole specimen having a width of 25.4 mm, a thickness of 3.17 mm and two holes of 4.75 mm diameter spaced 25.4 mm apart, tested in ambient laboratory air, at a stress ratio of R=0.1 and a frequency of 25 Hz]]. (See PO 41.77(b)(1) Resp. 2-3.) To summarize the amendments, Patent Owner asserts that claim 1 has been amended to correspond to the invention alloy in claim 1. (PO 41.77(b)(1) Resp. 4.) In this regard, the word “about” has been eliminated from the ranges of elements set forth in claim 1. Specific ranges of zinc, Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 7 copper, magnesium, and zirconium have been added. The “wherein” clause related to improved fatigue failure resistance has been amended by adding the recitation that the “log average fatigue life is calculated based on at least 16 specimens from at least 4 lots.” Patent Owner points to columns 5-6, Table II, column 6, lines 19-24, and Figure 1 of the ’719 Patent for support for these limitations. (PO 41.77(b)(1) Resp. 8-10.) For claim 3, as in claim 1, specific ranges for the elements of the alloy product have been added, and importantly, the “wherein” clause related to fatigue failure resistance has been deleted. (PO 41.77(b)(1) Resp. 6, 10-11.) Absence of Magnesium Silicide (Mg2Si) intermetallic particles In addition to the above discussed amendments, both claims 1 and 3 have been amended to recite that the “aluminum alloy product is absent of magnesium silicide (Mg2Si) intermetallic particles.” Patent Owner points to column 3, lines 27-50 of the ’719 Patent as providing support for this limitation. (PO 41.77(b)(1) Resp. 7.) Requester contends that the ’719 Patent does not enable this limitation because the ’719 Patent discloses that the Mg2Si particles are “absent” or “almost absent” and does not teach one of ordinary skill in the art how to fabricate an alloy where the Mg2Si intermetallic particles are “totally” absent. (Req. Comm. 7-8.) The Examiner did not comment on this limitation in the Examiner’s Determination. (See generally Ex. Det.) The ’719 Patent discloses: The inventors have discovered that an improvement in the invention alloy fatigue failure resistance is associated with Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 8 decreasing fatigue initiation by Mg2Si intermetallic particles. When the Si concentration is maintained below about 0.06%, particularly below about 0.04%, the usually observed Mg2Si in this alloy system is absent or almost absent, thereby significantly delaying the onset of fatigue failure. (Col. 3, ll. 32-38.) We observe that claims 1 and 3 as amended in Patent Owner’s Request to reopen recite at most 0.029% by weight silicon, which is below 0.06% and 0.04% disclosed in the ’719 Patent. The cited portion of the ’719 Patent discloses that lower amounts of silicon lead to the absence of Mg2Si intermetallic particles. Because the range of silicon recited in the claims includes an upper limit below that disclosed in the ’719 Patent as providing for the absence of Mg2Si intermetallic particles, we are not convinced that undue experimentation would have been required to produce an alloy product absent of Mg2Si intermetallic particles as recited in the claims. In re Wands, 858 F.2d 731, 737 (Fed. Cir. 1988). Rather, it appears that alloys having amounts of silicon recited in the amended claims would inherently be absent of Mg2Si intermetallic particles. 35 U.S.C. § 112, 2nd paragraph Rejection Claims 1, 2, 5, 6, and 8 As an initial matter, we disagree with Patent Owner that as a result of the amendments made to Claim 1, the composition of the alloy recited therein is limited to that of Example 1 (Lots A-D) in the ’719 Patent. Specifically, claim 1 as amended in Patent Owner’s Request to Reopen recites “0.01 to not greater than 0.039[%] iron,” whereas according to Table Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 9 II of the ’719 Patent, the percentage of iron ranges from 0.030 to 0.039 % by weight. (Col. 5, ll. 25-43.) Thus, the percentage of iron in the claims may be lower than the percentage of iron in the alloy product of Example 1. Likewise, amended claim 1 recites “0.01 to not greater than 0.029% silicon,” whereas according to Table II of the ’719 Patent, the percentage of silicon ranges from 0.014 to 0.029 % by weight. (Col. 5, ll. 25-43.) Regarding the “wherein” clause of claim 1, which recites specific requirements for the fatigue failure resistance, we stated: “one skilled in the relevant art would have been unable to ascertain whether an alloy satisfying the compositional requirements of claim 1 but having a fatigue life below the specified 355485 cycles would infringe or anticipate claim 1” due to “the uncertainty in the number and make up of alloys required to obtain the average fatigue failure resistance recited in the claims, [such that] the claims do not set forth with reasonable precision, a particular area as required in order to satisfy 35 U.S.C. § 112, 2nd paragraph.” (DOA 19.) Although disagreeing with the rejection, Patent Owner contends that “independent claim 1 has nonetheless been amended to require that the log average fatigue life is calculated based on at least 16 specimens from at least 4 lots, which is exactly how the log average fatigue life of Example 1 was tested.” (PO 41.77(b)(1) Resp. 5.) Patent Owner contends that as a result of claim 1 now specifying a minimum number of lots and specimens required to be tested to determine the log average fatigue life, the rejection has been overcome. (PO 41.77(b)(1) Resp. 5-6.) Requester II contends that claim 1 remains indefinite after the amendment because the specimens and lots recited in claim 1 are not related Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 10 to the remainder of the claim. (Req. Comm. 2-3.) In addition, Requester II argues that the portions of the ’719 Patent Specification related to the “wherein” clause does not disclose how to determine which lots need to be tested in order to meet the log average fatigue life recited in the claims. (Req. Comm. 3-5.) Accordingly, Requester II argues that the reasoning from the Decision on Appeal still applies, because depending on which specimens from Lots A-D disclosed in the ’719 Patent are selected, a log average fatigue life below 355485 would be obtained. (Req. Comm. 3-6.) The Examiner agreed with Requester II. (Ex. Det. 7.) The Examiner further explained that should more specimens be tested from Lots having lower Lot log average failure lifes, the log average of all Lots would be expected to be less than the log average fatigue life of 355485 cycles recited in claim 1. (Ex. Det. 7-8.) We agree with the Examiner and Requester II. For convenience, we reproduce Findings of Fact 4 and 5 from the Decision on Appeal pages 9-10: 4. Dr. Bray provides a table of the Log Average Fatigue Life of the alloys produced in Lots A-D: Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 11 (Bray 2009 Declaration,4 p. 11, para. 27.) 5. Dr. Bray provides a table of a summary of open-hole S-N fatigue life and Log Average Fatigue Life of the alloys produced in Lots A-H: (Bray 2009 Declaration, p. 8, para. 18.) The positions provided by Requester II and the Examiner illustrate that the “wherein” clause in claim 1 as amended in Patent Owner’s Request to Reopen is, like the compositional requirements of the alloy, not limited to the results disclosed in Example 1 of the ’719 Patent. Specifically, by reciting that the log average fatigue life is “at least” 355485 cycles, 4 The Decision on Appeal erroneously referenced a Rule 132 Declaration by Dr. Gary H. Bray executed on March 19, 2008, instead of the Rule 132 Declaration by Dr. Gary H. Bray executed on October 20, 2009 submitted with the response of October 23, 2009. (DOA 5, 9–10.) While the material is the same, we have corrected the paragraph numbering and the images produced. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 12 calculated based on “at least” 16 specimens from “at least” 4 lots, the claim, while including Example 1 (e.g., at col. 6, ll. 21–24, Fig. 1), is not limited thereto. The claim encompasses potentially higher log average fatigue life, calculated from potentially more than 16 specimens from more than 4 lots. The ’719 Patent does not provide any particular direction on how to select the number of specimens and lots to achieve the results recited in the claim beyond the specific data reported in Example 1. As a result, and as noted by Requester II, the same problem exists with respect to claim 1 as now currently amended as existed in the prior amended version discussed in the Decision on Appeal. In addition, we agree with the Examiner that the “wherein” clause does not identify how to select lots or the number of samples from each lot in order to satisfy the 16 specimens from more than 4 lots recitation. That is, according to the Bray 2009 Declaration (FF4, FF5), the log average fatigue life reported in Example 1 results specifically from the particular number of samples at each specific element concentration of each lot tested. However, claim 1 does not tie the number of specimens to the specific lot tested or the specific elemental composition of the alloy of the specific lot tested. Moreover, we have not been directed to any enlightenment in the Specification on a set standard for determining the make–up (i.e., identification) of the alloys to be tested, including—but not necessarily limited to—relevant identifying factors such as individual lot sizes, how a lot is selected from a given batch of alloy material, individual specimen sizes, or how specimens are to be selected from a given lot. Without a standard for selecting the lots and specimens and their sizes from a given Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 13 unspecified batch of alloy material, the fatigue test values recited in the claim would appear to be meaningless. Thus, one skilled in the relevant art still would have been unable to ascertain whether an alloy satisfying the compositional requirements of claim 1 would meet the log average fatigue life recited therein, because the amount of iron and silicon is not limited to the range disclosed in Example 1 and the lack of direction in the ’719 Patent as to the number and make-up of the specimens and lots of alloys required to obtain the average fatigue failure resistance recited in the claims. Accordingly, claim 1 as amended in Patent Owner’s Request to Reopen does not set forth with reasonable precision, a particular area as required in order to satisfy 35 U.S.C. § 112, 2nd paragraph. In re Moore, 439 F.2d 1232, 1235 (CCPA 1971); In re Packard, 751 F.3d 1307, 1313 (Fed. Cir. 2014) (Reh’g Denied). For claims 2, 5, 6, and 8, because those claims depend either directly or indirectly from claim 1, they also do not satisfy 35 U.S.C. § 112, 2nd paragraph for the same reasons. Claims 3 and 4 Patent Owner amended claim 3, deleting limitations relating to the average fatigue failure resistance that were added previously during reexamination. As a result, the Examiner determined that the rejection of claims 3 and 4 under 35 U.S.C. § 112, 2nd paragraph had been overcome. (Ex. Det. 6.) Requester II agrees. (Req. II 41.77(e) Comments 2.) We agree with the Examiner’s Determination. The “wherein” clause has been deleted from claim 3, which has been further amended to recite Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 14 narrower ranges for certain, but not all, of the compositional components of the alloy product from Example 1 of the ’719 Patent. Specifically, the percentages of iron and silicon of the alloy product recited in claim 3 are not limited to those of Example 1 of the ’719 Patent according to Table II. Accordingly, while claims 3 and 4 no longer stand rejected under 35 U.S.C. § 112, second paragraph, they are not limited to the alloy products of Example 1. 35 U.S.C. § 112, 1st paragraph Written Description Rejection Claims 1, 2, 5, 6, and 8 Patent Owner contends that in response to the Decision on Appeal, claim 1 has been amended: to correspond to the invention alloy compositions recited in Example 1 of the ‘719 patent. Since claim 1 now corresponds to the actual invention alloy compositions of Example 1 resulting in the claimed fatigue life, it is believed that the written description rejection under 35 U.S.C. § 112 has been overcome. (PO 41.77(b)(1) Resp. 4-5.) Requester contends that even after the amendment, the lower ends of the recited ranges of iron and silicon extend beyond the amounts used to generate Lots A-D of Table II, and as such, the claims lack written description support. (Req. Comm. 8.) The Examiner stated: claim 1 is now limited to the invention alloy compositions of claim 1 which resulted in the claimed fatigue life, however, one of ordinary skill in the art, in view of the ‘719 patent, still would not have been reasonably certain that Patent Owner had Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 15 invented an alloy product having the amounts of iron, silicon, and other elements, and the specifically claimed fatigue failure resistance value for the full scope of the claims. (Ex. Det. 5.) The Examiner further explained that one of ordinary skill in the art would have reasonably expected that the claimed value is representative only of the specific examples selected in the manner disclosed in Example 1 (as evidenced by the 2009 Bray Declaration). (Ex. Det. 5-6.) Both Patent Owner and Requester point to the Decision on Appeal, where we stated: “Importantly, the claims recite amounts of iron and silicon that extend beyond the specific amounts used to generate the experimental results and the average fatigue failure resistance recited in the claims.” (PO 41.77(b)(1) 4; Resp. Req. Comm. 7; Decision on Appeal 16.) As discussed above, claim 1 has not been limited to Example 1, either in the amounts of iron and silicon as well as in the calculation of log average fatigue life. Thus, we disagree with the Examiner’s position that claim 1 has been limited to claim 1. As a result, the reasoning in the Decision on Appeal still applies (DOA 15-17), and the rejection of claims 1, 2, 5, 6, and 8 has not been overcome because Patent Owner has not identified written description support for the full ranges recited in the claims. Claims 3 and 4 As discussed above, Patent Owner amended claim 3, deleting limitations relating to the average fatigue failure resistance that were added previously during reexamination. As a result, the Examiner determined that Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 16 the rejection of claims 3 and 4 under 35 U.S.C. § 112, 1st paragraph as lacking written description had been overcome. (Ex. Det. 5.) We agree with the Examiner’s Determination. The “wherein” clause has been deleted from claim 3, which has been further amended to recite narrower ranges for certain compositional components of the alloy product from Example 1 of the ’719 Patent. Accordingly, claims 3 and 4 no longer stand rejected under 35 U.S.C. § 112, first paragraph as lacking written description. 35 U.S.C. § 112 Rejection for Lacking Enablement Although the rejection under 35 U.S.C. § 112, first paragraph of claims 1-6 and 8 as lacking enablement was not designated as new ground of rejection in the Decision on Appeal, because independent claims 1 and 3 have been amended, we address the continued applicability of this rejection to the claims as discussed further below. Claims 1, 2, 5, 6, and 8 Patent Owner contends, similar to the rejection under 35 U.S.C. § 112, first paragraph for lack of written description, that because claim 1 has been amended to the actual alloy compositions of Example 1 resulting in the claimed fatigue life, that the enablement rejection has been overcome. (PO 41.77(b)(1) 4.) Requester contends that even with the amendments to claim 1, the rationale from the Decision on Appeal still applies and also that the amounts Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 17 of iron and silicon are not limited to the amounts in Example 1 of the ’719 Patent. (Req. Comm. 6-7.) In the Examiner’s Determination, the Examiner did not comment on the effect of the amended claim language on the rejection under 35 U.S.C. § 112, first paragraph of claims 1-6 and 8 as lacking enablement. (See generally Ex. Det.) As discussed above, claim 1 has not been limited to Example 1, both in the amounts of iron and silicon as well as in the calculation of log average fatigue life. Thus, we disagree with the Patent Owner’s position that claim 1 has been limited to claim 1. As a result, the reasoning in the Decision on Appeal still applies (DOA 11-14), and the rejection of claims 1, 2, 5, 6, and 8 has not been overcome. Claims 3 and 4 As discussed above, Patent Owner amended claim 3, deleting limitations relating to the average fatigue failure resistance that were added previously during reexamination. As also discussed above, claim 3 has been further amended to recite narrower ranges for certain compositional components of the alloy product from Example 1 of the ’719 Patent. Accordingly, claims 3 and 4 no longer stand rejected under 35 U.S.C. § 112, first paragraph as lacking enablement. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 18 Prior Art Rejections Claims 1, 2, 5, 6, and 8 Because claims 1, 2, 5, 6, and 8 as amended in Patent Owner’s Request to Reopen do not overcome the rejection in the Decision on Appeal under 35 U.S.C. § 112, 2nd paragraph, we decline to reach the prior art rejections of those claims for the reasons set forth in the Decision on Appeal. (DOA 20.) Claims 3 and 4 Because the rejection under 35 U.S.C. § 112, 2nd paragraph has been overcome with respect to claims 3 and 4, we review claims 3 and 4 with respect the prior art rejections previously applied to those claims, and which Requester contends still apply to the amended claims.5 (Req. Comm. 10-12, 14-17.) 5 Requester appears to acknowledge that the rejection of claims 3 and 4 under 35 U.S.C. § 102(b) as anticipated by Yamamoto, S., et al., Quantitative Estimation Method of Exfoliation Corrosion of High Strength Aluminum Alloys, J. Japan Inst. Metals, vol. 60 pp. 1187-1191 (“Yamamoto”) no longer applies and proposes a new rejection under 35 U.S.C. § 103(a) based on Yamamoto, which we decline to reach based on our affirmance of the rejections of claims 3 and 4 discussed below. (Req. Comm. 12-13; see Previous Decision 4.) Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 19 Anticipation Rejection Hunt Requester contends that the Examiner’s rejection of claims 3 and 4 under 35 U.S.C. §102(b) as anticipated by Hunt6 has not been overcome as a result of the amendment to the claims. (Req. Comm. 10-12; RAN 24.) The Examiner cited Hunt column 3, lines 15-19 (“[f]or every numerical range set forth, it should be noted that all numbers within the range, including every fraction or decimal between its stated minimum and maximum, are considered to be designated and disclosed by this description”), for the position that Hunt discloses the claimed ranges with sufficient specificity noting that the ’719 Patent contains the same statement in column 2, ll. 59-63. (RAN 24; see also Req. Comm. 11.) In particular, Requester argues with respect to silicon that “about 0.03” recited in Hunt should be construed to include “0.29% silicon” claimed by Patent Owner. (Req. Comm.) Patent Owner contends that Hunt’s ranges encompass an infinite amount of numbers, and thus Hunt does not disclose the recited ranges with sufficient specificity to anticipate the ranges recited in the claims. (App. Br. 15.) The dispositive issue on appeal is: Does Hunt disclose the amounts of alloy elements with sufficient specificity to anticipate claim 3? DISCUSSION For a rejection under 35 U.S.C. § 102 to be proper, the prior art “must clearly and unequivocally disclose the claimed [invention] or direct those 6 Hunt et al., U.S. Patent No. 5,221,377, issued June 22, 1993. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 20 skilled in the art to the [invention] without any need for picking, choosing, and combining various disclosures not directly related to each other by the teachings of the cited reference.” Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008), citing In re Arkley, 455 F.2d 586, 587 (CCPA 1972) (emphasis in original). We are persuaded that the Examiner erred in rejecting the claims. That is, we agree with Patent Owner’s contention that the ranges alloy elements, for example iron and silicon, disclosed in Hunt are not disclosed with sufficient specificity to anticipate the claimed ranges. Hunt discloses an alloy having low levels of iron and silicon, in amounts of about 0.03 to 0.1 % by weight for each element. (Col. 20, ll. 44-46; claim 4.) Although there is overlap between the range of iron recited in the claim (0.01 to not greater than 0.039) and the range of iron disclosed in Hunt, and the range of silicon recited in the claim (0.01 to not greater than 0.029%) abuts the range of silicon recited in Hunt, we cannot subscribe to the view that amounts of both iron and silicon that would fall within the range recited in the claim are disclosed in Hunt with sufficient specificity as to anticipate claim 1. Rather, one of ordinary skill in the art would have had to select from among the various combinations of iron and silicon described in Hunt, including amounts falling outside the ranges recited in the claims, in order to arrive at an amount falling within the recited range. As a result, we reverse the Examiner’s rejection of claims 1-6 and 8 as anticipated by Hunt. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 21 Obviousness Rejections Murtha in view of Agrawal As pointed out by Requester, the rejection of claims 3 and 4 under 35 U.S.C. § 103(a) as obvious over Murtha7 in view of Agrawal8 has not been overcome as a result of the amendment. (RAN 7-10; Req. Comm. 14-15.) In particular, claim 3 was amended in Patent Owner’s Request to Reopen to delete “about” before the weight percentages of iron and silicon, and with respect to iron, the upper limit was lowered from 0.044% to 0.039%. The claim now recites iron in an amount of 0.01 to 0.039% wt. and silicon in an amount of 0.01 to 0.029% wt. The teaching in Agrawal relied on by the Examiner states in relevant part: “Advantageously both iron and silicon will be present in amounts less than 0.03 weight percent of the total weight of the alloy and even more advantageously iron and silicon will be present in amounts of less that [sic, than] 0.01 weight percent of the total weight of the aluminum alloy.” (Agrawal, col. 2, ll. 1-7; RAN 8-9.) Thus, because Agrawal discloses amounts of iron and silicon that include the amounts of iron and silicon in claim 3 as currently amended, the Examiner’s findings with respect to Agrawal are still applicable. (RAN 8-9; Agrawal, col. 2, ll. 5-7; col. 4, l. 27 – col. 5, l. 7.) It is well established that, when there is a range disclosed in the prior art, and the claimed invention overlaps or falls within that range, there is a presumption of obviousness. In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003); Iron Grip Barbell Co. v. USA Sports, Inc., 392 F.3d 1317, 7 Murtha, U.S. Patent No. 5,496,426, issued March 5, 1996 (“Murtha”). 8 Agrawal, U.S. Patent No. 4,867,805, issued Sept. 19, 1989.

Even if the location values do not precisely overlap, they “are so close that prima facie one skilled in the art would have expected them to have the same properties,” shifting the burden to the applicant to show they are different. Titanium Metals Corp. v. Banner, 778 F.2d 775, 783 (Fed. Cir. 1985). In this regard, we emphasize that Agrawal discloses aluminum alloy products having the percentages of iron and silicon disclosed therein inhibit cavitation as a result of primary particles formed of iron and silicon, and that the aluminum alloy products have superior engineering strain to fracture, strain rate sensitivity and true stress, providing a reason to have selected such amounts. (RAN 9; Agrawal, col. 4, l. 27 – col. 5, l. 7, col. 6, ll. 3-6.) Regarding the limitation that the aluminum alloy product is “absent of magnesium silicide (Mg2Si) intermetallic particles,” as discussed above, the ’719 Patent directly relates this absence to the silicon concentration in the alloy product. (Col. 3, ll. 32-38.) Thus, the Examiner had basis to find that the alloy product produced in accordance with Murtha in view of Agrawal would inherently be absent of Mg2Si intermetallic particles, shifting the burden to Patent Owner to show otherwise. See In re Best, 562 F.2d 1252, 1255 (CCPA 1977). Hunt in view of in view of ASM Handbook, Lutjering, Magnusen, Dubost, and Schwarmann As pointed out by Requester, the rejection of claims 3 and 4 under 35 U.S.C. § 103(a) as obvious over Hunt in view of in view of ASM Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 23 Handbook,9 Lutjering,10 Magnusen,11 Dubost,12 and Schwarmann13 has not been overcome as a result of the amendment.14 (RAN 19-23; Req. Comm. 15-17.) In particular, the Examiner found that the ASM Handbook discloses that reducing the amount of impurities in an alloy in order to reduce strain and early crack nucleation. (RAN 20.) The Examiner found that Lutjering discloses a 7075 alloy with lowered iron and silicon content. (RAN 20-21.) We observe that as pointed out by Requester, Lutjering discloses alloys with iron and silicon percentages of 0.02% falling within the amended amounts in claim 3 of iron and silicon (iron in an amount of 0.01 to 0.039% wt. and silicon in an amount of 0.01 to 0.029% wt., each with higher fracture toughness compared to those with higher iron and silicon percentages. (Req. Comm. 17, FN8; Luterjing, p. 198, Fig. 29.) The Examiner concluded that it 9 ASM Handbook (Vol. 19, pages 785-800, ASM International, Dec. 1996). 10 Lutjering, G., et al., Fatigue and Fracture of Aluminum Alloys, Aluminum Transformation Technology and Applications, pages 171-210. 11 Magnusen, Paul E., et al., Final Report: The Role of Microstructure on the Fatigue Durability of Aluminum Aircraft Alloys, O.

(Req. Comm. 15-17; see Previous Decision 5; RAN 19-20.) Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 24 would have been obvious to improve the fatigue life of an alloy disclosed by Hunt by decreasing the content of silicon and iron impurities as taught by the ASM Handbook and Lutjering. (RAN 21.) Additionally, the Examiner pointed to Magnusen and Dubost as recognizing the detrimental effect of large particles caused by the presence of iron and silicon on fatigue lifetime tests as a reason to decrease the presence of iron and silicon to the recited levels in the claims. (RAN 21-23.) Thus, the Examiner’s rationale still applies even after the amendments to claim 3 set forth in Patent Owner’s 41.77(b)(1) Response. Regarding the limitation that the aluminum alloy product is “absent of magnesium silicide (Mg2Si) intermetallic particles,” as discussed above, the ’719 Patent directly relates this absence to the silicon concentration in the alloy product. (Col. 3, ll. 32-38.) Thus, the alloy product produced in accordance with the combination of prior art would inherently be absent of Mg2Si intermetallic particles. See In re Best, 562 F.2d at 1255. Patent Owner’s Arguments With respect to the prior art, Patent Owner refers to arguments related to unexpected results presented in Patent Owner’s Appeal Brief15 pages 23-34 as well as the Grandt Declaration16 paragraphs 27-29 and the Bray 15 Appeal Brief filed October 18, 2012, pages 23-34. 16 Rule 132 Declaration by Dr. Alten F. Grandt, Jr. executed on June 30, 2010, submitted with the response of February 4, 2011 (“the Grandt Declaration”) (App. Br., App’x B). Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 25 2011 Declaration17 paragraphs 20-30, and contends that because the aluminum alloy product recited in claim 3 “exactly matches the compositions of the invention alloys of Example 1, the claim scope of claim 3 is commensurate in scope with the alloys defining the unexpected results shown in Example 1 of the ‘719 Patent.” (PO 41.77(b)(1) Response 6.) In the Appeal Brief, Patent Owner concedes that in view of the prior art of record, it would have been obvious to one of ordinary skill in the art to try to lower the amounts of iron and silicon in some aluminum alloys to improve fracture toughness, but that it would have been unexpected to achieve high levels of fatigue resistance at low levels of iron and silicon. (App. Br. 23.) Importantly, Patent Owner’s arguments center around the position that none of the cited prior art of record can achieve the average fatigue life recited in claim 3, which recitation has been removed from claim 3 as a result of Patent Owner’s amendment. (App. Br. 26; citing Bray 2011 Declaration, paras. 8-19.) Patent Owner also argues that the unexpected results are commensurate in scope with the claims, because alloys having lower amounts of iron and silicon down to the minimum levels claimed would achieve better fatigue performance. (App. Br. 33-34.) PRINCIPLES OF LAW “In order to establish unexpected results for a claimed invention, objective evidence of non-obviousness must be commensurate in scope with the claims which the evidence is offered to support.” In re Clemens, 622 17 Rule 132 Declaration by Dr. Gary H. Bray executed on July 1, 2010, submitted with the response of February 4, 2011 (“the Bray 2011 Declaration”) (App. Br., App’x E). Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 26 F.2d 1029, 1035 (CCPA 1980). Finding the claim scope broad, and the “probative value of appellants’ evidence . . . quite narrow,” the court concluded this “is not a case in which the probative value of a narrow range of data can be reasonably extended to prove the unobviousness of a broader claimed range.” Id. at 1036. Cf. In re Kollman, 595 F.2d 48, 56 (CCPA 1979) (where it was held that the nonobviousness of a broader claimed range was proven by a narrower range of data, when one having ordinary skill in the art could “ascertain a trend in the exemplified data which would allow him to reasonably extend the probative value thereof.”) ANALYSIS We observe that contrary to Patent Owner’s position, claim 3 is not limited to or reasonably broader than the scope of Example 1 of the ’719 Patent for the reasons discussed above. Thus, we are not persuaded that the evidence provided by Patent Owner is commensurate in scope with the claims. Nonetheless, the portion of the record that Patent Owner points to as discussed above relies on the Bray 2009 Declaration as evidence that the fatigue failure resistance recited in the claims would have been unexpected because of an established trend of fatigue failure resistance. In particular, Dr. Bray provides a graph (“the Bray Graph”) based on the experimental results provided in the ’719 Patent, Lots A-D, in order to illustrate the extent of the improvement in reducing the iron and silicon content from a standard 7055 alloy and for allegedly establishing a trend for unexpected results. (Bray 2009 Declaration, para. 28.) Patent Owner contends that Lot D of Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 27 Example 1 in the ’719 Patent provides evidence that the maximum claimed level of 0.029 wt. % silicon achieved the claimed fatigue life properties. (App. Br. 32.) Patent Owner argues also that alloys having lower amounts of iron and/or silicon would achieve even better fatigue performance down to the minimum level of 0.01wt. % according to the Bray Graph. (App. Br. 32.) The Bray Graph plots the weight percentage of iron and silicon versus the log average life of Lots A-D. (Bray 2009 Declaration, para. 28.) Only two of the graphed points, presumably corresponding to Lots B and C, meet the average fatigue life argued by Patent Owner. (See FF 4.) The log average fatigue life of Lots A and D, 326521 and 205922 cycles at 207 MPa respectively, fail to rise to the log average fatigue life level of 355485 cycles that forms the basis for the position in the Declarations that the results would have been unexpected. (See Resp’t Br. 18; FF 4.) Stated in a different way, Lot D, which the inventors characterized as inventive and can itself be considered as an alloy that can be further subdivided into 4 lots and 16 specimens, provided cycle lives that appear to be no better than prior art alloys. Although the Specification of the ’719 Patent makes clear that a log average fatigue life of 355485 cycles is obtained from the alloy products produced in Example 1, claim 3 is not limited to the alloys of Example 1, but contain amounts of iron and silicon that extend beyond those used for the alloy products of Example 1. As a result, we are not persuaded by the Grandt Declaration and the Bray 2011 Declaration paragraphs 20-30, which emphasize the results obtained from Example 1 as being unexpected. Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 28 Thus, notwithstanding that claim 3 is not commensurate in scope with Example 1, we are not persuaded by Dr. Bray’s assertion that a reliable trendline may be ascertained from the log average fatigue life data. (Bray 2009 Decl., para. 30.) While it is true that “the unobviousness of a broader claimed range [can be] proven by a narrower range of data,” there must be basis to predict that the ascertained trend could be reasonably extended to the claimed broader range. In re Clemens, 622 F.2d 1029, 1035-36 (C.C.P.A. 1980). In this case, the fact that two of the four lots in Example 1 fall below the level of fatigue life associated with unexpected results, raises concern about the probative value of the narrower range to prove the nonobviousness of the broader range. When it cannot even be predicted that a specific lot having the claimed silicon and iron levels will possess the claimed fatigue levels, we cannot find basis in such data for predicting the performance of silicon and iron levels outside those specifically tested. This is consistent with the ’719 Patent, which states that the “lifetime and magnitude of the improvement may differ.” (’719 Patent, col. 6, ll. 12-18.) Therefore, Patent Owner’s reliance on the disclosure of the ’719 Patent, which states that fatigue improvements will be observed in other specimens, as evidence that the recited average fatigue life will be improved from the results in Example 1 as the amounts of iron and silicon are lowered is not persuasive. The Evidence as a Whole In view of the discussion above evaluating both the evidence of obviousness and the evidence of nonobviousness, we determine that the Appeal 2016-008385 Reexamination Control 95/000,285 & 95/001,085 Patent 7,097,719 29 evidence of obviousness outweighs the evidence of nonobviousness. Specifically, we view the evidence in favor of reducing the iron and silicon content in the alloys of Murtha to within the claimed ranges as suggested by Agrawal or reducing the iron and silicon content in the alloys of Hunt by decreasing the content of silicon and iron impurities as taught by the ASM Handbook, Lutjering, Magnusen and Dubost as outweighing the evidence of nonobviousness in view of discussed deficiencies thereof. Accordingly, Patent Owner’s amendment submitted with the Response filed under 37 C.F.R. 41.77(b)(1) is insufficient to overcome all of the prior art rejections of record for claims 3 and 4 in this reexamination. Thus, we modify our Decision on Appeal to reverse the rejection of claims 3 and 4 as obvious over Murtha and Agrawal and Hunt in view of ASM Handbook, Lutjering, Magnusen, Dubost, and Schwarmann pro forma, such that the Examiner’s rejections of claims 3 and 4 under 35 U.S.C. § 103(a) are affirmed. DECISION In sum: 1. The affirmance of the Examiner’s rejections of claim 14 over prior art is moot in view of the cancellation of claim 14; 2. The Examiner’s rejection of claims 1, 2, 5, 6, and 8 under 35 U.S.C. § 112, 1st paragraph as lacking enablement remains affirmed; 3.
