Thomas describes that (1) the “collected data is then stored in the database 130,” (2) the collected “data is stored in a data structure, generally referred to as a user’s profile,” and (3) the collected “data is logically linked to an event, or situation, that initiated the user’s input.” Id. at 3:56–61. Thomas describes creating or establishing a user profile by simulator 120 recording “the user’s decision/input” and storing “the user’s input in the field or sub-profile associated with the particular situation and/or event.” Id. at 4:67–5:5, Fig. 6. Patent Owner does not dispute Petitioner’s showing for element [1.3]. Also, contrary to Patent Owner’s arguments, we must consider what Thomas discloses rather than whether Thomas uses the exact claim term “instruction sets.” Cf. Gleave, 560 F.3d at 1334 (a reference does not have to satisfy an ipsis verbis test to disclose a claimed element).

      “B. Level of Ordinary Skill in the Art Petitioner argues that a person of ordinary skill in the art would have had “(1) a bachelor’s degree in electrical engineering, computer engineering, computer science, systems engineering, or equivalent course work with two to three years of work experience in computer vision, image/video processing, and/or machine learning; or (2) a master’s degree in electrical engineering, computer engineering, computer science, systems engineering, or equivalent course work with a focus in computer vision, image/video processing, and/or machine learning.” Pet. 3–4 (citing Ex. 1003 ¶ 41). Petitioner’s description of the level of ordinary skill in the art is supported by the testimony of Petitioner’s declarant, Dr. Jason Janet. Ex. 1003 ¶ 41.

We need not resolve this claim construction issue in order to resolve the parties’ disputes about the asserted ground of unpatentability.

      “We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003) (“First, we look to the claim language to determine if, as a matter of logic or grammar, [the recited steps] must be performed in the order written.”).” slip op. at 8

      “Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). In response, Patent Owner argues that Petitioner’s obviousness analysis is flawed because “there is no articulated reasoning regarding what specific element of claim 45 Buibas . . . does not disclose.” Prelim. Resp. 19–20. In other words, according to Patent Owner, Petitioner “failed to perform a proper obviousness analysis because Petitioner has failed to identify anything in the claims that Buibas lacks disclosure of for Ground 1A.” Id. at 20. Based on the present record, we determine that Petitioner has set forth sufficient reasoning to support a motivation to combine Buibas and Sinyavskiy for purposes of institution, as well as sufficient reasoning to support the conclusion that one of ordinary skill would have had a reasonable expectation of success in making the combination. We do not agree with Patent Owner’s argument that Petitioner’s obviousness analysis is flawed because it fails to identify what is lacking in Buibas’s disclosure. To the contrary, Petitioner explains that Buibas “broadly suggests” that its spiking neural networks “can be partitioned into modules for different tasks or behaviors” but “discloses little detail about the partitioning,” and that Sinyavskiy’s more detailed disclosure of partitioning spiking neural networks would fill in these details. See Pet. 12–13, 14–15, 24. Petitioner also relies on Sinyavskiy’s more detailed disclosures concerning partitioning the network to satisfy limitations [45.1] and [45.6]. Id. at 23–27, 35. Thus, Petitioner has sufficiently identified what is missing in Buibas (a detailed disclosure of partitioning spiking neural networks) and how that missing information is provided by Sinyavskiy (by disclosure of specific techniques for partitioning spiking networks).” slip op. at 13

    The Board instituted inter partes review of claims 1–10 on both asserted § 103 grounds: Yu and Hansen with WWiSE.

    RulingsInstitution decision
    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

      “The touchstone in determining whether a reference constitutes a printed publication is whether it was publicly accessible at the critical time. SRI Int’l v. Internet Security Systems, Inc., 511 F.3d 1186, 1194 (Fed. Cir. 2008). Public accessibility exists where the reference document “has been disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art exercising reasonable diligence, can locate it.” Id. (quoting Bruckelmyer v. Ground Heaters, Inc., 445 F.3d 1374, 1378 (Fed. Cir. 2006)). Patent Owner argues that a relevant person of ordinary skill using reasonable diligence would not reasonably have located the paper residing on the TGn ftp site. Prelim. Resp. 9–10. We discern three potential avenues for public availability in the assertions set forth by Petitioner: (1) availability to the members of TGn through the Wireless World website; (2) availability to others through the ftp site; and (3) availability to others through Mentor. We address each in turn, taking into account Patent Owner’s arguments.” slip op. at 6

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “B. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art [“POSITA”] at the critical time “would have had at least a master’s degree in electrical engineering or similar discipline, and/or two to three years of experience working or conducting research in the field of wireless communication protocols, or an equivalent combination of education and experience.” Pet. 8 (citing Ex. 1003 ¶ 71). Patent Owner does not contest this assessment. Prelim. Resp. 3. For purposes of this Decision, we adopt Petitioner’s proposed level of ordinary skill, as it appears to be consistent with the specification of the ’146 patent and the prior art of record.” slip op. at 18

      “claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. § 282(b).” 37 C.F.R. § 42.100(b). Under this standard, the words of a claim generally are given their “ordinary and customary meaning,” which is the meaning the term would have to a person of ordinary skill at the time of the invention, in the context of the entire patent including the specification. Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). Here, neither party sets forth any claim construction. Pet. 9; Prelim. Resp. 3. Therefore, we construe the claims pursuant to § 42.100(b).” slip op. at 19

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “Patent Owner argues, and we agree at this stage, that a general desire to combine two competing proposals as expressed in Hansen does not specifically motivate incorporating ER header bits into the standard, as asserted by Petitioner. Prelim. Resp. 43–45. Although insufficient by itself to support the asserted combination, such an expressed desire to combine proposals provides some impetus to consider features from each proposal as a compromise to create the new IEEE standard, and we consider that in our consideration of Petitioner’s other reasons.” slip op. at 32

      “4. Discussion At this stage of the proceeding, the prior art status of Zhang is the only dispute between the parties as to the patentability challenge based on Zhang and Maltsev. See Prelim. Resp. 47–56. For the purpose of institution, we need not determine whether Zhang is entitled to the filing date of ’900PROV, because, as explained above with respect to the unpatentability challenge based on Hansen and WWiSE, we have determined that there is a reasonable likelihood that the Petitioner will prevail with respect to at least one of the claims challenged in the Petition pursuant to 35 U.S.C. § 314. 37 C.F.R. § 42.108(a) (“When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.”). The ’566 Patent also claims the benefit of the filing date of Provisional Application No. 61/235,909, filed on August 21, 2009. Ex. 1001, code (60), 1:8–18. “Petitioner does not acquiesce that the ’566 patent is entitled to the priority date of the ’909 provisional.” Pet. 1. We look forward to the development of the full trial record as to the prior art status of Zhang to the ’566 Patent. We note that, although the burden of production may shift between the parties during trial on this issue, the burden of persuasion to show that Zhang is prior art to the ’566 Patent always remains with Petitioner.

      “Memorandum titled Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (June 21, 2022)9 (“Fintiv Memo”). The Fintiv Memo sets forth, inter alia, that the Board will not discretionarily deny institution under § 314(a) when a petitioner submits a so-called Sotera stipulation, i.e., the petitioner 9 Available at https://www.uspto.gov/sites/default/files/documents/ interim_proc_discretionary_denials_aia_parallel_district_court_litigation_ memo_20220621_.pdf “stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.” Fintiv Memo 7 (citing Sotera).

    • Strike new argumentNew argument disregardedDecided for petitioner

      “As an initial matter, for the first time in the Sur-reply Patent Owner contends that we should exercise discretion to deny institution on the basis of the HP district court proceeding and the Acer district court proceeding. Patent Owner did not previously address discretionary denial on the basis of these district court proceedings, but instead addressed “the two parallel district court proceedings involving . . . Dell and Lenovo.” Prelim. Resp. 56; see id. at 56–57. Patent Owner’s arguments are belated and outside the proper scope of a proper sur-reply, and should not be considered. “Generally, a reply or sur-reply may only respond to arguments raised in the preceding brief.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019) (“CTPG”)10 74 (citing 37 C.F.R. § 42.23). It “does not mean to proceed in a new direction with a new approach as compared to the positions taken in a prior filing.” Id. In any event, even if we were to consider Patent Owner’s belated arguments, Patent Owner does not direct us to evidence to support its argument that HP and Acer are real parties-in-interest or privies. Nor does Patent Owner direct us to evidence demonstrating any involvement or control by HP or Acer in this proceeding. Thus, HP and/or Acer’s actions, including whether they raise these same grounds of unpatentability in their respective district court proceedings, should not be imputed to Petitioner.” slip op. at 11

      “Petitioner alleges and provides evidence that July 2005 WWiSE was posted to, and continuously publicly available from, sources maintained by IEEE from July, 2005, until the earliest priority date of the ’707 patent. Petitioner further alleges and provides evidence that any interested member of the public could access July 2005 WWiSE during this time period. Although Patent Owner contends that WWiSE could not have been located by a skilled artisan, Petitioner’s evidence shows that WWiSE was made available to members of the TGn Task Group of the IEEE 802.11 WLAN Working Group without any restrictions of confidentiality or limits on dissemination. And, Petitioner provides evidence that interested members of the public would have known to look for WWiSE because the proposals made to IEEE in this time frame were frequently discussed in industry publications. In addition, we note that WWiSE lists over fifty contributors that were associated with a wide variety of technology companies in this space. Ex. 1005, 2–4. The parties may want to consider during trial, and in accordance with our Rules, whether this evidences or otherwise supports public availability. We determine that Petitioner has established the public accessibility of WWiSE sufficiently for the purpose of institution.” slip op. at 22
