Claims 16–27 were not shown unpatentable because Petitioner failed to account for limitations 16[b] and 16[i] and their counterparts across the asserted obviousness grounds.
RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“Patent Owner proposes that a person of ordinary skill in the art “would have a Bachelor of Science degree in Electrical Engineering, Computer Engineering, Computer Science, Human Computer Interaction, or a related technical field, with at least one year of experience working in the field of user interfaces and/or content management.” PO Resp. 11 (citing Ex. 2040 ¶ 53). The Decision on Institution adopted Petitioner’s proposed level of ordinary skill in the art. Inst. Dec. 10. We find Patent Owner’s stated level to be less precise than that proposed by Petitioner in that the modifier “at least” used by Patent owner imposes no upper bound on the amount of experience possessed by one of ordinary skill in the art. Also, Patent Owner states: “The difference between the Board’s definition and Patent Owner’s (EX2040. ¶53) does not change the arguments set forth herein.” PO Resp. 11. Thus, we continue to adopt Petitioner’s stated level of ordinary skill in the art.4 4 All of our findings and conclusions would still be the same, however, had we applied Patent Owner’s articulation of the level of ordinary skill in the art.” slip op. at 8
- Prior constructionPrior construction adoptedDecided for patent owner
“In its Reply, Petitioner does not assert that the district court’s construction is incorrect. We agree with Patent Owner that the district court’s construction is better than Petitioner’s proposed construction, because for reasons indicated by Patent Owner, which are not disputed by Petitioner, settings in the computer, e.g., dedicated folders for each user are the user profiles, rather than simply data alone of any kind. Further, when asked about the appropriateness of the district court’s construction, counsel for Petitioner expressed that Petitioner has no objection to the Board’s adopting the district court’s construction for “user profile”: JUDGE LEE: So, you’d be fine with just going with the District Court’s construction? MR. HEINTZ: Yes, Your Honor. Tr. 15:22–24. For the foregoing reasons, we adopt the district court’s construction for “user profile,” i.e., “a collection of settings and information associated with a user.”” slip op. at 13

“PO Resp. 30–31 (Figure 26 omitted). In its Reply, Petitioner still does not provide an articulated reason for placing user profile selection buttons, labeled with user names, within Horn’s panes 2601 or 2602. Reply 12–14. Although Horn does describe personalized profile, Petitioner points to no disclosure of Horn as to how a user would have selected his or her own profile from among a plurality of user profiles. Petitioner presents no reason for placing these user profile selection buttons, labeled with user names, gleaned from or suggested by Baumgartner, within either pane 2601 or pane 2602 in Horn’s workspace view. Further, pane 2602 contains “a list of all collections defined by MFS and the user,” and pane 2601 lists the source examined by the user to create his or her collections. Ex. 1005, 19:41–46. That disclosure suggests the contents of panes 2601 and 2602 are tied to one particular user. No rational basis is articulated by Petitioner to place user profile selection buttons within these panes which appear to be in the profile space of one user. For the foregoing reasons, Petitioner has not adequately accounted for limitation 16[b].” slip op. at 22
- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious. Id. (“[T]he applicant must also convey to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.”) (emphasis in original). One does that by such descriptive means as words, structures, figures, diagrams, formulas, etc., that fully set forth the claimed invention. Although the exact terms need not be used in haec verba, see Eiselstein v. Frank, 52 F.3d 1035, 1038, 34 USPQ2d 1467, 1470 (Fed.Cir.1995) (“[T]he prior application need not describe the claimed subject matter in exactly the same terms as used in the claims. . . .”), the specification must contain an equivalent description of the claimed subject matter. A description which renders obvious the invention for which an earlier filing date is sought is not sufficient. Lockwood v. American Airlines, Inc., 107 F.3d 1565 (Fed. Cir. 1997).” slip op. at 31

“II. ANALYSIS A. Legal Standards Petitioner bears the burden to demonstrate unpatentability. Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). For purposes of institution, Petition bears the burden to establish, by a reasonable likelihood that at least one of the challenged claims would have been obvious over the cited art. See 35 U.S.C. § 314(a). Where unpatentability rests on a document that is prior art to a challenged patent but for that patent’s priority claim to an earlier effective filing date, such a priority claim is not presumed valid. PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1305 (Fed.

“understanding of a person of ordinary skill in the art at the time of the invention. Id. at 13, 17. Petitioner asserts that a person of ordinary skill in the art would have had at least a Master’s degree in electrical engineer-ing or a similar discipline, and/or at least two to three years of experience working or conducting research in wireless commu-nication protocols, or an equivalent combination of education and experience. Pet. 6 (citing Ex. 1003 ¶¶ 71, 72). Patent Owner does not contest Petitioner’s assertion as to the level of ordinary skill in the art. Prelim. Resp. 6. We are persuaded, on the present record, that Petitioner’s proposal is consistent with the problems and solutions in the ’146 patent and prior art of record.

“action under 35 U.S.C. § 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b) (2022). The Board is required to construe “only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.” Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Petitioner and Patent Owner, in extended briefing, contest the construction of the phrase “detecting, from the received wireless packet, the second header field which repeats the first header field,” as it appears in claim 1. Pet. 9; Prelim. Resp. 1; Pet. Reply 3; PO Sur-Reply 3. However, both parties appear to agree that the plain and ordinary meaning of the term should apply. See Pet. 6; Prelim. Resp. 15. Further, Petitioner has clarified that its statements as to the scope of the term are directed to its assertions that the ’146 patent lacks support for the claimed subject matter in its parent applications. Pet. Reply. 5–6. Consequently, we address claim construction arguments in their context of the parties’ priority contentions. See infra at II.D.1.” slip op. at 7

“Patent Owner has shown sufficient written description support for the claims, including the disputed “detecting” limitation. The “decode-to-learn- ‘D’” description in the specification of the ’146 patent and in the provisional application to which the ’146 patent claims priority describe a specific procedure for the claimed “detecting, from the received wireless packet, the second header field which repeats the first header field.”3 See Ex. 1001, 2 Petitioner specifically asserts that Huang qualifies under 35 U.S.C. §102(b). Pet. 2, 19 (“by more than a year”). However, Huang’s patent issuance date of April 28, 2020 does not qualify under § 102(b) because it is less than one year before the December 29, 2020 filing date of the ’146 patent. Nevertheless, Petitioner has made an effective showing that Sun would qualify as prior art sufficient to shift the burden of production to Patent Owner. 3 Patent Owner does not explicitly show support for each of the applications in the priority chain. Patent Owner also cites to a Pre-Grant Publication rather than the underlying application despite the fact that such a Publication may include amendments to the originally filed application that would not evidence written description. See 37 C.F.R. § 1.215 (a); MANUAL OF PATENT EXAMINING PROCEDURE §1121; Ex. 2003, 7 (showing amendments 3:1–11; Ex. 2001 ¶ 35; Ex. 1008, 5–6; PO Sur-Reply 6. The “D” information is received in the wireless packet, and the receiver determines therefrom whether there is a second header field that repeats the first header field. See Ex. 1008, 5–6; PO Sur-Reply 6. The written description further includes descriptions of other embodiments for receiver detection with variable repetition, including detection “without knowing D a priori.” Ex. 1001, 2:18–3:59.” slip op. at 9

“But, even accepting these premises, we disagree with the conclusion Petitioner asks us to draw from them. In particular, Petitioner appears to contend that we should find that the ’974 application does not provide written description support for the claims of the ’638 patent merely because the scope of the claims includes a configuration that is not expressly described in that document. See Pet. 15–16, 22. But this reflects a misunderstanding of the law—a claim can be broader than the embodiments disclosed. See, e.g., Rexnord, 274 F.3d at 1344 (“An applicant is not required to describe in the specification every conceivable and possible future embodiment of his invention.”); see also Ethicon Endo-Surgery, Inc. v.

“D. Obviousness Grounds Petitioner contends that the subject matter of claims 1–30 of the ’638 patent would have been obvious over various combinations of Oakes-I, Oakes-II, Medina, and Roach (collectively, “the asserted references”). Pet. 5, 32–100. Petitioner argues that the asserted references are prior art because the claims of the ’638 patent are not entitled to a priority date earlier than July 28, 2017. Id. at 4–5, 11–29. Patent Owner contends that Petitioner fails to establish a reasonable likelihood of success because Petitioner fails to sufficiently show that the asserted references qualify as prior art. Prelim. Resp. 18–59. Having reviewed the parties’ arguments and evidence, we determine that Petitioner has not demonstrated a reasonable likelihood that it will prevail in showing that the asserted references are prior art,8 and as a result, Petitioner fails to sufficiently show that any claim would have been unpatentable based on the asserted references.” slip op. at 16
