    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)InstitutedInstituted

      “Under 35 U.S.C. § 314(a), an inter partes review may not be instituted unless the information presented in the petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons stated below, we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one claim. We, therefore, institute inter partes review as to all of the challenged claims of the ’202 patent and all of the asserted grounds of unpatentability.” slip op. at 2

      “The two proposals are materially similar in the education requirement, but differ marginally in professional experience required (three versus five years). See supra. While we are persuaded, on the present record, that both Petitioner’s and Patent Owner’s proposals are consistent with the problems Petitioner’s proposal is a better reflection of the level of skill in the prior art, and we therefore adopt it for this decision. Our decision would not change, however, if we had applied Patent Owner’s proposed level of ordinary skill.” slip op. at 12

    • BurdenMixed

      “Figure 6 of Rauhala has been annotated by Patent Owner to show that the parallel connection (outlined in red) including resistors R1, R2. R3 and switches ka, kb is outside the signal path (highlighted in yellow) through differential amplifier 61. Prelim. Resp. 38. Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala. We further determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its challenge to claims 7 and 19 as anticipated by Rauhala.” slip op. at 26

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Instituted

      “We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process. More pertinent to our facts is the Federal Circuit’s decision in Microsoft Corporation v. Uniloc, 2017 LLC, No. 2021- 2039, 2022 WL 11531235 (Fed. Cir. Oct. 20, 2022), that addresses steps in a method claim. Reversing the Board’s determination that a petitioner had 6 See Ex. 1001, 14:5–6 (claim 7), 14:41–42 (claim 11), 15:18–19 (claim 13), and 17:28–29 (claim 19). Circuit concluded that the Board had misconstrued the claims to require separate acts: We agree with [petitioner] that the Board misconstrued the claims to require that the comparing and determining step are performed by two separate acts in a certain order. Nothing in the intrinsic record requires such a narrow construction, and neither party presented this construction to the Board. Without any such evidence, we decline to impose such a narrow claim construction. Microsoft Corp., 2022 WL 11531235, at *3 (citation and footnote omitted). We find that at this stage, Petitioner has made a sufficient showing that this limitation is met by Rauhala. Pet. 31–33; Baker Decl. ¶¶ 111–114.” slip op. at 22

    The Board instituted IPR on all grounds for claims 1–17, finding a reasonable likelihood that at least one challenged claim would be shown unpatentable.

      “review. 35 U.S.C. § 314; 37 C.F.R. § 42.4(a). The standard for institution is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted “unless the Director determines . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” After considering the parties’ arguments and evidence, and for the reasons set forth below, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing with respect to at least one challenged claim of the ’023 patent. Accordingly, we institute an inter partes review of claims 1–17 of the ’023 patent. See SAS Inst., Inc. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018).” slip op. at 2

    • Skill levelSkill level board ownDecided for petitioner

      “For purposes of this Decision, we generally accept Petitioner’s proposed definition of the person of ordinary skill in the art (or ordinarily skilled artisan), which appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosures of the ’023 patent; however, we also agree with Patent Owner that such a definition should be flexible enough to include a person with a lesser academic degree and having experience working in the field, such as an engineer with clinical experience in ophthalmic surgery, as well as a medical doctor, such as an ophthalmic surgeon with experience working with medical optics and lasers. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the appropriate level of ordinary skill in the art may be reflected in “the prior art itself”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Such an expanded definition of the person of ordinary skill in the art, including aspects of both parties’ definitions, is appropriate based on our review of the record, which demonstrates individuals having a broad array of scientific degrees that collaborate as a team. We note, however, that our decision to institute trial in this proceeding would not change were we to adopt Patent Owner’s proposed definition.” slip op. at 8

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

      “On this record, we agree with Patent Owner that the disputed preamble phrase is limiting. “[C]lear reliance on the preamble during prosecution to distinguish the claimed invention from the prior art transforms the preamble into a claim limitation because such reliance indicates use of the preamble to define, in part, the claimed invention.” Catalina Mkt’g Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808–09 (Fed. Cir. 2002). Here, the Examiner expressly allowed the claims in view of the Examiner’s Amendment changing “scanning system” to “cataract surgery scanning system,” thereby transforming this portion of the preamble into a limitation. Ex. 1006, 13, 15, 18; see Catalina Mkt’g, 289 F.3d. at 808. Furthermore, contrary to Petitioner’s arguments, the record appears to suggest that there are structural differences between the optical systems of cataract surgery systems on the one hand and corneal surgery systems on the other. See Ex. 2006, 5:30–36; Ex. 2009, 1209–10. Thus, on this record, we are not persuaded that the language added by the Examiner represents merely an intended use for the disclosed system. In view of the foregoing, for purposes of this Decision, we construe the preamble phrase “cataract surgery scanning system” recited in independent claims 1, 8, and 12 to be limiting.” slip op. at 10

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

      “The ’023 patent explains that a “cataract incision” is an incision created “to allow access for the lens removal instrumentation.” Ex. 1004, 10:17–19. The potential ambiguity in the claim comes, as Petitioner notes, from the fact that the cataract incision of claim 1 “only partially extend[s] through the target tissue,” which would not appear to provide immediate “access to an eye chamber of the patient’s eye.” Pet. 10; Ex. 1004, 10:19– 23, 14:15–21. Although somewhat ambiguous on its face, the prosecution history provides guidance as to how this claim phrase is to be interpreted. Phillips, 415 F.3d at 1317 (“Like the specification, the prosecution history provides evidence of how the PTO and the inventor understood the patent.”). During prosecution, the Applicants explained that the invention allows “straight cataract incisions [to be] made at the correct location,” and that partially penetrating cataract incisions are advantageous because they allow the laser delivery system to be located in an “unsterile field,” with the final penetrating incision to be made “by a physician after a patient has been moved to a sterile field.” Ex. 1006, 52–53. The Applicants then explained that despite the fact that partially penetrating cataract incisions do not fully for the lens removal instruments,” as that term is used in the ’023 patent. Id. at 52 (noting the purpose of “partially penetrating cataract incisions” is “to allow access for lens removal instruments”), 55 (“In short, none of the cited art teaches . . . to deliver the first treatment pattern to the target tissue to form partially penetrating cataract incisions – i.e. incisions that allow access for the lens removal instruments.”). The Examiner agreed with this reasoning. Id. at 15 (agreeing that the prior art did not teach or suggest partially penetrating cataract incisions that provide “access to the eye chamber of the patient’s eye”). Given these disclosures, we agree with Patent Owner that “provides access to an eye chamber of the patient’s eye” in claim 1 means that the partial incision is a starting incision, made in the appropriate shape and location, that allows complete access for lens removal instrumentation when completed, for example, by the surgeon. In view of the foregoing, we construe the claim phrase “cataract incision therein that provides access to an eye chamber of the patient’s eye, the incision . . . only partially extending through the target tissue” to require “a partially penetrating cataract incision that, when completed by the” slip op. at 12
