      “cameras.” Pet. 6 (citing Ex. 1002 ¶¶ 36–38). Petitioner further contends “[a]n advanced graduate degree in the disciplines cited above may make up for the work experience indicated above.” Id. Patent Owner does not dispute and applies Petitioner’s proposed level of skill. PO Resp. 6. We find that Petitioner’s proposal is reasonable and consistent with the ’832 patent specification and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36). Pacurariu likewise describes aligning and resizing/cropping of a captured image to correct poor orientation. See, e.g., Ex. 1005 ¶¶ 1, 3, 45–56, Figs. 5A–5C. The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77). Pacurariu similarly uses sensors and measures tilt angle of the camera. Id at 21–22 (citing, e.g., Ex. 1005 ¶¶ 51–52, Fig. 6; Ex. 1002 ¶ 78). Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52). Petitioner, with support from credible testimony of Dr. Katsaggelos, explains how the teachings of Thomason and Pacurariu could be successfully combined. Id. at 23 (citing, for example, Ex. 1002 ¶ 81). A person of ordinary skill in the art could have known that Thomason’s system could be improved by saving rotation data for each video frame and correcting images on a frame-by-frame basis. Id. at 23–24. The testimony of Dr. Katsaggelos is credible in this regard. Ex. 1002 ¶¶ 80–81. Petitioner and Dr. Katsaggelos explain the references’ teachings and, based on these teachings, assert that a person having skill in the art would have had reason to combine with reasonable expectation of success based on those teachings. Reason to combine may properly come from the references themselves. KSR Int’l Co., 550 U.S. at 418 (explaining reason to combine may come from “interrelated teachings of multiple patents”). Based on the evidence presented, Petitioner establishes by a preponderance of the evidence that a person having ordinary skill in the art would have had reason to combine the teachings of Thomason and Pacurariu with a reasonable expectation of success. Ex. 1002 ¶¶ 76–81, 89–92; Ex. 1004 ¶¶ 4, 8–9, 27, 29, 35; Ex. 1005 ¶¶ 26, 41, 46, 51–52, 55–57, Figs. 6, 7.” slip op. at 27

We first consider whether Patent Owner has demonstrated “that its products are coextensive (or nearly coextensive) with the challenged claims,” resulting in a rebuttable presumption of nexus. Id. at 33. If not, that “does not end the inquiry into secondary considerations”; “the patent owner is still afforded an opportunity to prove nexus by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id.

We are also persuaded by Dr. Suhling’s testimony that the “combination of Ball, Fogal, and Mostafazadeh would require no modification of the multichip modules in Ball and Fogal: rather Mostafazadeh merely explains in more detail methods known in the art for creating chips with adhesive surfaces.” Ex. 1002 ¶ 239; see also id. ¶¶ 62– 69 (describing prior art methods for applying adhesive to the backside of a wafer). For the foregoing reasons, we find that Petitioner has demonstrated that a person of ordinary skill in the art would have had a reasonable expectation of successfully combining Ball, Fogal, and Mostafazadeh.” slip op. at 46

      “Petitioner, relying on the testimony of Dr. Rogers, contends that a person of ordinary skill in the art would have [had] a bachelor’s degree or equivalent in any of the pharmaceutical sciences with at least 5 years of experience in solid state chemistry; a master’s degree in any of the pharmaceutical sciences with at least 3 years of experience in solid state chemistry; or a Ph.D. in any of the pharmaceutical sciences with 1 year of experience in solid state chemistry. Pet. 8 (citing Ex. 1008 ¶¶ 24–28). Petitioner further states that such “[a] person could also have qualified as a [person of ordinary skill in the art] with some combination of (1) more formal education and less technical or professional experience or (2) less formal education and more technical or professional experience.” Id. Patent Owner does not dispute Petitioner’s proposed definition of a person of ordinary skill. See generally MTA, RMTA. Having considered the parties’ arguments and evidence, we adopt the level of ordinary skill in the art proposed by Petitioner, because it is consistent with the disclosures of the ’363 patent and the prior art of record. We note, however, that neither party contends that the outcome of this case would differ based on our adoption of any particular definition of a person of ordinary skill in the art.” slip op. at 12

      “In our Preliminary Guidance, we construed “for a pharmaceutical composition” to mean “in combination with pharmaceutically acceptable excipients,” based on the ’363 patent’s definition providing that “[t]he terms ‘formulation’ or ‘pharmaceutical composition’ as used herein refers to the drug in combination with pharmaceutically acceptable excipients.” Prelim. Guid. 5–6 (citing Ex. 1001, 12:26–28; Ex. 2010, 17:11–12; Ex. 2011, 26:26– 27). We also encouraged the parties to address whether “for a pharmaceutical composition,” which appears in the preamble of substitute claims 28 and 29, is limiting, as opposed to a statement of intended use or purpose. Id. at 6. Following our Preliminary Guidance, the parties submitted further arguments concerning the term “for a pharmaceutical composition.” Patent Owner argues the term requires that the claimed process provide STS that is sufficiently pure for use in a pediatric patient (see RMTA 8–11) and that the word “drug” in the ’363 patent’s definition of “pharmaceutical composition” requires that the anhydrous STS is of sufficient purity for pharmaceutical use. Reply RMTA 3. Petitioner argues that the construction set forth in our Preliminary Guidance was correct. See Sur-reply RMTA 2–3. Having considered the arguments and evidence, we do not further construe the term “for a pharmaceutical composition” in this Decision because, as discussed in our analysis of obviousness below, it is not necessary to construe the term in order to determine whether Petitioner has met its burden of demonstrating by a preponderance of the evidence that proposed substitute claims 28 and 29 are unpatentable. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am.

    • PTAB / AIA Trials › Motions to amend / substitute claimsMotion to amend, grantedGranted

      “1. Reasonable Number of Substitute Claims A motion to amend must “propose a reasonable number of substitute claims.” 35 U.S.C. § 316(d)(1)(B); see 37 C.F.R. § 42.121(a)(3) (“A motion to amend may cancel a challenged claim or propose a reasonable number of substitute claims.”). Patent Owner proposes the same number of substitute claims as the original challenged claims that are cancelled, i.e., a one-to-one substitution for a total of two substitute claims. MTA 2; RMTA. “There is a rebuttable presumption that a reasonable number of substitute claims per challenged claim is one (1) substitute claim.” Lectrosonics, Paper 15 at 4; see 37 C.F.R. § 42.121(a)(3). Petitioner does not argue otherwise. See generally Opp. RMTA. Therefore, we determine that Patent Owner proposes a reasonable number of substitute claims. 2. Support in the Original Disclosure Patent Owner has identified written description support in the originally filed disclosure of the ’363 patent for the new limitations added for the proposed substitute claims. See RMTA 5–8. We have reviewed Patent Owner’s assertions of support in the original disclosure for the proposed revised substitute claims and determine that sufficient support exists. Petitioner does not argue otherwise. See generally Opp. RMTA. Therefore, we determine that Patent Owner has met this requirement. 3. Respond to a Ground of Unpatentability “A motion to amend may be denied where . . . [t]he amendment does not respond to a ground of unpatentability involved in the trial.” 37 C.F.R. § 42.121(a)(2)(i). Patent Owner asserts that the proposed revised substitute claims are patentable over the combination of references that forms the basis of the obviousness ground on which we instituted trial. RMTA 12–13. Petitioner does not argue otherwise. See generally Opp. RMTA. Therefore, we determine that Patent Owner has met this requirement. 4. Scope of the Claims Patent Owner asserts that the proposed revised substitute claims do not enlarge the scope of original claims 18 and 20. RMTA 5. We have reviewed Patent Owner’s assertion that the purity amendments of proposed revised substitute claims 28 and 29 narrow the claims’ scope. Id. Petitioner does not argue otherwise. See generally Opp. RMTA. Therefore, we determine that Patent Owner has met this requirement.” slip op. at 17

    • BurdenNot shown unpatentable

      “determine the evidence relied on by Petitioner does not support Petitioner’s position that a person of ordinary skill in the art would have been motivated to combine Levenson, Sherman, Edwards, and USP. Petitioner’s contention that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman is based on Dr. Rogers’s testimony that “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151; see Pet. 36, 38. Dr. Rogers further testified it would have been obvious to add Edwards’s dehydrating step to the preparation of STS pentahydrate “which is obtained following the teachings of Levenson and Sherman” because “Edwards itself discloses dehydrating [STS] pentahydrate.” Id. ¶ 154. The Petition included these arguments even though they were inconsistent with Petitioner’s previous statement, during the Sherman prosecution, that Levenson taught STS heptahydrate, and therefore “does not provide any teaching with respect to [STS] pentahydrate.” Ex. 2013, 97. This prior inconsistent statement undercuts Petitioner’s rationale for combining Levenson, Sherman, and Edwards in this proceeding. Moreover, Petitioner’s rationale for combining the references in this proceeding is inconsistent with its statements about Levenson during the Sherman prosecution. Recognizing this inconsistency, Petitioner now takes the position that the Petition and Dr. Rogers’s testimony were incorrect. Paper 32; see Tr. 21:14–22:7, 59:1–2 (reemphasizing that “Petitioner maintains the statements that it made in the Sherman prosecution regarding Levenson”). Petitioner attempts to rationalize the inconsistency between its statements in the Sherman prosecution (including that “Levenson does not provide any teaching with respect to [STS] pentahydrate”) and its position in this proceeding by arguing that Dr. Rogers relies on Levenson as teaching surface activation “regardless of any particular hydrates Levenson discloses.” Tr. 22:8–9. That argument is not persuasive, because Dr. Rogers’s declaration clearly states the primary reason for his opinion that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman: “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151. Contrary to Petitioner’s argument, Dr. Roger’s reliance on the surface activation teachings of Levenson is because he believes that both references pertain to STS pentahydrate; the surface activation teachings are not stated as an independent reason to combine the references. Id. Petitioner provides no further explanation of how a person of ordinary skill in the art would have been motivated to combine Levenson’s teachings regarding manufacture of STS heptahydrate with Sherman’s and Edwards’s teachings regarding STS pentahydrate, or how a person of ordinary skill would have regarded the difference between STS hydrates. Dr. Rogers’s acknowledgement of stability differences among STS hydrates highlights the insufficiency of Petitioner’s showing in this regard. See Ex. 2005, 35, 39.

      “does not explain how any of the supposed advantages of Feild are relevant to How-767 or how the combination would achieve these supposed advantages. Petitioner identifies reducing fabrication steps, eliminating polishing steps, and high electromigration performance as benefits of Feild’s fabrication method. See Pet. 63 (citing Ex. 1011, 2:48–3:10; Ex. 1006 ¶ 149). Dr. Lall’s cited testimony identifies these advantages compared to the prior art techniques discussed in Feild that use additional polishing steps, multiple-step processing, and the use of chemical mechanical polishing. See Ex. 1006 ¶ 149 (citing Ex. 1011, 2:16–32, 2:20–30, 2:48–3:10). Petitioner also asserts that How-767 presents Figure 1 as an exemplary cross-sectional view of a generic integrated circuit and never suggests that the precise structure of Figure 1 is required. See Pet. 65 (citing Ex. 1003, 1:21–22). On this basis Petitioner contends that a person of ordinary skill in the art would have understood that other cross-sectional interconnection arrangements could be used. See id. (citing Ex. 1006 ¶ 152). Petitioner asserts that a person of ordinary skill in the art would have understood that forming How-767’s routing structure according to the interconnect structure taught by Feild would involve a simple substitution of Feild’s cross-sectional interconnect structure for How-767’s exemplary cross-sectional interconnect structure to obtain predictable results. See id. (citing Ex. 1006 ¶ 153). Accordingly, we understand that Feild’s advantages of reducing fabrication steps, eliminating polishing steps, and high electromigration performance would be achieved by forming How-767’s routing structure according to Feild’s cross-sectional interconnect structure. In sum, based on the entire trial record, we determine that Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify How-767 by “forming How-767’s routing structure according to the interconnect structure taught by Feild” in order to obtain the advantages of reducing fabrication steps, eliminating polishing steps, and high electromigration performance.
