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

      “Pursuant to 35 U.S.C. § 314(a), institution of review requires the information in the record to demonstrate a reasonable likelihood that Petitioner would prevail with respect to at least one challenged claim. Applying that standard on behalf of the Director (37 C.F.R. § 42.4(a)), we institute an inter partes review to determine whether Petitioner demonstrates by a preponderance of the evidence that claims 1–8, 10–16, and 18 are unpatentable, considering all grounds in the Petition directed to those claims. We do not institute review as to claims 9 and 17 on any ground because they have been disclaimed. See 37 C.F.R. § 42.107(e).” slip op. at 2

      “disclaimer,” and “[n]o inter partes review will be instituted based on disclaimed claims.” 37 C.F.R. § 42.107(e). As a result of the statutory disclaimer, claims 9 and 17 are no longer regarded as claims challenged in the Petition. See Vectra, 162 F.3d at 1383 (“This court has interpreted the term ‘considered as part of the original patent’ in section 253 to mean that the patent is treated as though the disclaimed claims never existed.”) (citing Guinn v. Kopf, 96 F.3d 1419, 1422 (Fed. Cir. 1996)); see also Sanofi-Aventis U.S., LLC v. Dr. Reddy’s Labs., Inc., 933 F.3d 1367, 1372–75 (Fed. Cir. 2019) (disclaimer of claims during District Court patent infringement litigation “mooted any controversy” over the disclaimed claims, ending the Article III case or controversy requirement for District Court jurisdiction). In considering Federal Circuit precedent and our rules, we conclude we cannot institute a trial on claims that have been disclaimed, and, thus, no longer exist. Our conclusion is consistent with the statutory scope of inter partes review as laid out in 35 U.S.C. §§ 311(b) and 318(a) and is not at odds with SAS, supra. See, e.g., SAS, 584 U.S. at 367 (recognizing that “the claims challenged ‘in the petition’ will not always survive to the end of the case; some may drop out thanks to the patent owner’s actions”). Accordingly, we treat claims 9 and 17 as having never been part of the ’056 patent, such that Petitioner cannot seek inter partes review of those claims. Thus, we deny institution of review as to whether disclaimed claims 9 and 17 are unpatentable per Petitioner’s Grounds Three and Four.” slip op. at 32

      “Petitioner argues “[n]o terms need to be construed . . . to resolve unpatentability.” Pet. 16–17. “Patent Owner contends that the claim terms should receive their ordinary and customary meaning in light of the specification and prosecution history, as understood by a person of ordinary skill in the art.” Prelim. Resp. 8. Patent Owner does not proffer any constructions for particular terms. See id. Based on the arguments and evidence presented at this time, we determine no explicit construction is needed to resolve the parties’ controversy. See Realtime Data, LLC v.

      “II. ANALYSIS A. Standard of Review When rehearing a decision on petition, the Board will review the decision for an abuse of discretion. See 37 C.F.R. § 42.71(c). An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Arnold Partnership v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004). The party challenging the decision has the burden of showing a decision should be modified, and the request for rehearing must identify specifically all matters the party believes the Board misapprehended or overlooked. 37 C.F.R. § 42.71(d). In its Request for Rehearing, the dissatisfied party must (1) “specifically identify all matter that party believes the Board misapprehended or overlooked” and (2) identify the place where each matter was previously addressed.

See id. at 213. Neither of these quoted passages links the objects of the access matrix model to the columns of the relational database system, described in connection with the authorization lists, or provides any other adequate explanation as to how Denning discloses that the object of the access matrix model “corresponds” to the columns of the relational database system. In the Petition, Petitioner and its declarant also state that Denning discloses that the access matrix is applicable to database systems. Pet. 3; Ex. 1010 ¶ 54 (citing Ex. 1006, 192).

      “LLC. See Decision 9–10. As we stated in our Decision, a party may not petition for post-grant review if it has filed a civil action challenging the validity of a claim of the patent before the petition is filed. 35 U.S.C. § 325(a)(1); 37 C.F.R. § 42.201(a); see Securebuy, LLC, CBM2014-00035, (PTAB Apr. 25, 2014) (Paper 12, precedential) (explaining that 35 U.S.C. § 325(a)(1) applies to covered business method patent review proceedings).

However, this also does not describe the objects of the access matrix model as columns of the relational database system. Petitioner alternatively argues that Denning’s objects at the top of the columns of the access matrix model are associated with a data category, when “data category” is given the broadest reasonable construction adopted in the Decision. Pet. Req. 3, 9. Petitioner states: “[f]or example, M1 refers to a division of data that shares a common attribute of being stored in memory segment M1.” Id. Petitioner, however, does not identify where this argument was raised in the first instance in the Petition, and we can find no such argument in the Petition. We could not have overlooked or misapprehended an argument that was not raised in the Petition. We, thus, are not persuaded by Petitioner that we abused our discretion in denying institution of covered business method patent review of claims 15, 31, 33, and 47 on the ground of obviousness over Denning. slip op. at 14

      “terms, and we agree, for purposes of this decision, that claim 42 does not require a specific quantity of DME in the distillation overhead. We do not agree with Petitioner, however, that the Singh and ’507 patent disclosures are identical with respect to the addition of water to distillation column 22. As indicated in our Decision, both Singh and the ’507 patent describe adding small amounts of water to column 22 for the purpose of inhibiting impurity formation. See Dec. 5–6. The ’507 patent, however, includes additional description of adding water to column 22 for the purpose of producing DME in the distillation overhead. See id. at 7 (citing Ex. 1002, col. 11). This additional description of adding water to produce DME in the distillation overhead does not refer back to the description of adding water as an inhibitor (see Ex. 1002, 10:9–32), or otherwise indicate that the small amounts of water used to inhibit impurity formation in the ’507 patent and Singh processes would produce DME in a distillation overhead. In addition, for the reasons explained in our Decision (Dec. 25–26), Petitioner has not persuaded us that the prosecution history of the ’507 patent includes an admission by Patent Owner that the addition of any amount of water to the distillation step would result in DME in an overhead stream. See Req. Reh’g 10. In sum, Petitioner has not convinced us that our Decision was based on an erroneous claim interpretation or that we overlooked evidence that the addition of any amount of water in the steps common to the Singh and the ’507 patent processes would necessarily result in the presence of DME in a distillation overhead. With respect to Petitioner’s assertions regarding Akinori, we note the Petition relied on Akinori as evidence that DME was necessarily produced in the ’095 patent process. See Pet. 43. Petitioner did not explain how Akinori was relevant to show the presence of DME in the distillation overhead of Singh.

Petitioner cites Böhnke for such a technique. Pet. 49. We are persuaded by Petitioner’s analysis on the present record.” slip op. at 5

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
