  • RemandDecided for patent owner

    “challenge fails even if Petitioner’s summary of the references were correct because Petitioner did not present a sufficient reason to modify Feldman to include a current zoom level in its search request. FWD 56. The Federal Circuit vacated this finding specifically and contemplated that there would be a “consideration of obviousness” on remand. CAFC Dec. 10–11. That consideration requires more than determining whether any one reference teaches a current zoom level and a search, generally. See FWD 56 (quoting MTA Reply 10). Here, Petitioner’s challenge is based on modifying the Feldman-Jackson combination. So the Board must determine on remand whether the Feldman-Jackson combination in view of knowledge of a POSA meets the claim limitations at issue. We also disagree to the extent that Petitioner argues that the Board is precluded from considering additional arguments on the relevant issues on remand. The Board’s preliminary guidance on the Motion to Amend stated that Petitioner’s obviousness rationale was based on convenience and this reason was not sufficiently supported: reference lacks a sufficient explanation of why one of ordinary skill in the art would have added the zoom levels in the prior art to Feldman. See id. At most, Petitioner argues that it would be convenient to “specify the area the user desires to search for content” in this way. Id. at 14. But, on this record, Petitioner has not sufficiently explained why it would be convenient to do so in Feldman. See id. Nor has Petitioner sufficiently explained how or why the prior-art features confer this convenience. See id. MTA PG, 13. Because the Board’s conclusion turned on the lack of sufficient explanation, the briefing that followed was limited to Petitioner’s obviousness rationale. See, e.g., MTA Reply 9–12, MTA Sur-reply 1–12. Under these specific circumstances, we determine that it would be procedurally fair to fully consider the arguments on remand about whether the cited prior art teaches or suggests the limitations recited in the substitute claims. And, as discussed above, the Federal Circuit has directed the Board to consider obviousness. CAFC Dec. 10–11.” slip op. at 11

    “Patent Owner’s proposal is most like Petitioner’s alternative proposal which would include a bachelor’s degree and two years of experience. However, Patent Owner does not provide a specific number of years of industry experience and Patent Owner would include mixed-signal IC design as an alternative to analog circuit design. We consider analog circuit design to be most pertinent to the problems and solution discussed in the ’074 patent. See Ex. 1001, 1:15–2:44. In addition, we find credible Petitioner’s argument that an ordinarily skilled artisan with a bachelor’s degree would have had two years of experience, whereas Patent Owner’s proposal does not provide a specific number of years. Thus, we determine that a person of ordinary skill in the art would have had a bachelor’s degree and two years of experience in analog circuit design.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

    “We agree with Petitioner that “gm boosting” is the only gm enhancement referred to in the ’074 patent, that the ’074 patent uses the terms “gm enhanced” and “gm-boost” synonymously, and that Patent Owner has failed to point to any credible intrinsic evidence of this alleged distinction. Although, “[i]n the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings, CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed. Cir. 2000), in this case there is evidence to the contrary. In particular, the ’074 patent never refers to “gm enhancement” as a function separate from “gm boosting.” Indeed, the transistors (368, 370, and 382) that Patent Owner identifies as performing the function of “gm enhancement” are disclosed as part of a “gm-boost stage.” Ex. 1001, 5:8–24. Patent Owner’s alleged separation of Figure 3B into distinct “gm boosting” and “gm enhancement” is not consistent with the intrinsic evidence and is based on the conclusory testimony of Dr. Taylor. Thus, based on the evidence of record, we disagree with Patent Owner’s proposed construction distinguishing the terms “gm enhanced” and “gm-boost” in claim 1. Rather, we find persuasive Petitioner’s argument that a person of ordinary skill in the art would have regarded these terms to be synonymous. We need not otherwise construe these two terms to resolve the contested issues in this proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

Pet. 25–26; Ex. 1002 ¶¶ 67–68. The evidence of record also suggests that an enable/disable function was well known in the art and that it would have been within the level of ordinary skill in the art to add such a function to a biasing circuit, taking into consideration any known tradeoffs.

To the contrary, we are persuaded by Petitioner’s argument that Lee is analogous art, under at least the first Clay criterion, because it “discloses various techniques for deploying electrodes from the tip of an RF ablation device.” Pet. 17.” slip op. at 25

    “Patent Owner does not identify any legal requirement for petitions to illustrate proposed combinations of prior art features. Indeed, the very statute identified by Patent Owner as “requiring petitions to set forth challenge grounds ‘with particularity’” (see PO Resp. 36) calls for the requisite particularity to be “in writing,” not by illustration. See 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if . . . (3) the petition identifies, in writing and with particularity . . . the grounds on which the challenge to each claim is based.”). Simply put, there is no legal requirement to provide multiple illustrations of a proposed combination of prior art features (as Patent Owner implies), let alone a single illustration (as Petitioner has done).” slip op. at 28

    “a POSA would have had an apparent reason to make Racz’s modified device. Pet. 22–27. We need not address these additional arguments and evidentiary citations, however, as Petitioner has demonstrated by a preponderance of the evidence that implementing deployable filaments on the distal tip of an RF ablation device was a known technique for expanding and controlling the ablation volume. Thus, so long as there would have been a reasonable expectation of success in making Racz’s modified device (addressed infra), the combination would have been obvious. See Intel Corp., 61 F.4th at 1380 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.”); Medichem, 437 F.3d at 1165 (“[A]n obviousness determination requires not only the existence of a motivation to combine elements from different prior art references, but also that a skilled artisan would have perceived a reasonable expectation of success in making the invention via that combination.”).” slip op. at 31

    “improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. In this case, we must determine whether one of ordinary skill in the art would recognize that applying the teachings of Fitz and Lee of deploying multiple filaments to increase and control the ablation volume to Racz’s distal tip would improve Racz’s device in the same way. For us to resolve this question in Petitioner’s favor, Petitioner must provide “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” Id. at 418 (citing In re Kahn, 441 F.3d at 988). However, bodily incorporation, i.e., “an actual physical substitution of” Lee’s filaments into Racz is not required. See In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“It is well-established that a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.”); In re Nievelt, 482 F.2d 965, 968 (CCPA 1973) (“Combining the teachings of references does not involve an ability to combine their specific structures.”).” slip op. at 30

    “11. Balancing the Graham Factors After weighing all the evidence submitted by the parties in light of the Graham factors, we determine Petitioner has demonstrated by a preponderance of the evidence that the claims 1, 3–10, 18–26, 28, and 29 would have been obvious over Racz, Fitz, and Lee. As discussed above, Petitioner’s evidence establishes that the combination of Racz, Fitz, and Lee teaches every limitation of claims 1, 3–10, 18–26, 28, and 29 and that an ordinarily skilled artisan would have been motivated to combine Racz, Fitz, and Lee with a reasonable expectation of success. Further, as discussed above, Patent Owner’s evidence of secondary considerations is entitled to little, if any, weight because Patent Owner fails to establish nexus. Consequently, after considering all the evidence in the record both for and against patentability, we determine that Petitioner has shown by a preponderance of the evidence that claims 1, 3–10, 18–26, 28, and 29 would have been obvious over Racz, Fitz, and Lee. E. Ground B: Obviousness in view of Racz, Fitz, Lee and Young ’965 Petitioner contends that claims 1–10, 18–26, and 28–29 are also obvious over Racz, Fitz, Lee, and Young ’965. Pet. 62–67. Patent Owner argues that Young ’965 does not cure the alleged deficiencies in Ground 1, is directed to tumor ablation not neurotomy, would require a substantial redesign of Racz’s modified device, and there is no motivation to combine.

Reply 7 (quoting Ex. 1012, 5:59–67). We disagree. Instead, we agree with Patent Owner that Suzuki’s irregular-surface smoothing describes covering defects, not suppressing the underlying cathode’s topography. PO Sur-reply 5. The smooth-surface passage that Petitioner highlights comes immediately after two sentences describing inevitable “defects,” “pinholes,” and “foreign matter” on the cathode surface and before a sentence describing “ensuring the formation of the layer 22, which is substantially defect-free.” Ex. 1012, 5:52–67. Suzuki’s organic barrier 20 “makes a smooth surface” by covering defects because the defects are the only source of the “irregularity” that Suzuki refers to here. Id. We note Mr. Humphrey’s testimony, which we credit in this regard, that the “defects are created incidentally on the surface of the underlying layer and are generally not considered to be part of the underlying layer’s topography, which is a macroscopic property by design” and that the organic layer is not a planarization layer because it would reproduce the topography of the underlying layer. Ex. 2018 ¶¶ 47–48.
