    “to both cases vacating and remanding in part and affirming in part our Final Written Decisions. Appeal Dec. With respect to Petitioner’s appeals, the Federal Circuit addressed the “dictionary routine” claims (claims 14–19 and 33–40) and the “normalization” claims (claims 43–46). Appeal Dec. 7–14. For the “dictionary routine” claims, the Federal Circuit vacated and remanded, stating that In sum, as Google contends and we now hold, the “dictionary routine” claims can be practiced by use of an already-created dictionary, and do not also require the automatic creation of a dictionary. The Board needs to consider Google’s evidence and argument by applying this construction of the automatically classifying and storing limitation, and using this understanding to determine whether Conlon may, in fact, render the “dictionary routine” claims obvious (and, relatedly, whether its prior distinctions of Conlon may be immaterial). Appeal Dec. 10–11. For the “normalization” claims, the Federal Circuit also vacated and remanded, stating that our “decision to exclude Google’s rebuttal argument and supplemental declaration is based on a clear factual error,” so on remand we “must include evaluation of the evidence and argument Google provided in reply.” Id. at 13–14. With respect to Patent Owner’s cross-appeals, the Federal Circuit affirmed. Id. at 14–16.” slip op. at 3

    “The Federal Circuit concluded that Petitioner’s construction of “automatically classifying and storing” (as recited in limitation [14.3]), is correct. Appeal Dec. 8. That is, “the ‘dictionary routine’ claims can be practiced by [the] use of an already-created dictionary, and do not also require the automatic creation of a dictionary.” Id. at 10; see also Reply 7 (the limitation is “directed to the use of a dictionary function to automatically look up words and their syntax”); Appeal Dec. 8 (“nothing about the term . . . would inform a person of ordinary skill in the art that automatic ‘creation’ of a database, in addition to the ‘use’ of an already-created database, is a requirement of the dictionary routine claims”); id.

(agreeing with Petitioner that “the specification describes the ‘dictionary routine’ as the act of looking up words already in the database”); id. at 9 (stating that “[i]t is notable, as well, that the specification nowhere describes automatically creating a dictionary; all instances of creating dictionary entries rely, at least in part, on manual data entry by users”). As directed by the Federal Circuit, we will apply this construction in our analysis.8 Id. 8 Patent Owner argues that the Federal Circuit “cherry-picks” and misinterprets the patents’ specifications, and “ignores the clearly contrary specification language.” PO Remand Br. 4–5, 10; id. at 8 (arguing that that the specification clearly set forth the definition of the claim term, and “the Board must accept term definitions . . . above all external definitions”).

    “We agree with Petitioner that claim 43 is obvious over the combination of Conlon, Miller, and Fong. The Federal Circuit stated, “[i]n this context, ‘normalization’ generally refers to de-duplicating and simplifying database entries (for instance, combining entries for ‘car’ and ‘automobile’).” Appeal Dec. 4 (cited at Pet. Response Br. 5). This is consistent with the disclosure in the ’433 patent. E.g., Ex. 1001, 16:55– 17:24 (discussing, for example, “recogniz[ing] that the differently named data elements in different structures are actually the same data element . . . is referred to as normalizing the names of the same data elements,” “recogniz[ing] that the same named data elements in different structures are actually different data elements . . . is referred to as normalizing the names of the different data elements,” and “normalizing multiple single data elements”). This is also consistent with how Fong describes “normalization.” Ex. 1029, 76 (The “Function” of “Normaliz[ing] the collection of entities” is to “[r]emove redundancies and detect errors”); see also Ex. 1057 ¶ 226. Patent Owner’s arguments that Fong’s normalization is “different” from the normalization described in the ’433 patent does not persuasively rebut Petitioner’s arguments. As Petitioner points out, Patent Owner does not provide a construction for “normalization,” despite claiming that the term is “defined” in the ’433 patent. Pet. Remand Resp. Br. 6; PO Remand Br. 13. Moreover, although Patent Owner purports to identify differences between the ’433 patent and Fong, the “normalization” applied is expressly recited in limitations [43.1.1], [43.1.2], and [43.2], and the subsequent actions taken on those normalized databases (i.e., comparing and recording) are recited in limitations [43.3]–[43.5]. That is, the “normalization” required by the claim is reflected in the claim language itself, and is broader than argued by Patent Owner. See In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) (“It is not the function of this court to examine the claims in greater detail than argued by an appellant, looking for nonobvious distinctions over the prior art”). Patent Owner does not explain how these purported “differences” (e.g., that Fong may require the use of “database keys,” “identifiers,” “entities,” or determining ‘non-key attributes’ from key attributes) impacts the claim language, or Petitioner’s showing. See EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir. 1985) (A prior art reference “must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect”). For the same reasons, as well as those set forth by Petitioner, we are also not persuaded by Patent Owner’s arguments that each DBMS requires a normalization process that is customized for it. Pet. Remand Resp. Br. 6–7. These arguments by Patent Owner also are not commensurate with the scope of the claim language, which does not recite a DBMS, and generally recites “normalizing” or “normalized” without regard to the DBMS. Id. Dr. Jansen provides an example of a database in unnormalized form that is converted into a normalized form, based on Fong’s four conditions, as applied to the claim language. See Reply 31–35; Ex. 1057 ¶¶ 226–261. Therefore, we are not persuaded by Patent Owner’s arguments that Petitioner has not explained how the example maps onto the limitations. PO Remand Resp. Br. 6–12. Patent Owner’s complaint that Dr. Jansen created the graphic in the example does not undermine Petitioner’s showing. E.g., Trial Practice Guide,14 I.G., (“Experts may testify about the teachings of the prior art and how they relate to the patentability of the challenged claims.”). We find Dr. Jansen’s testimony credible and persuasive in explaining why the combination of Conlon and Fong teaches the claim limitations. After considering the properly presented evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that the combination of Conlon, Miller, and Fong teaches the limitations in claim 43, that one of ordinary skill in the art would have been motivated to combine the teachings of Conlon, Miller, and Fong, and that claim 44 would have been obvious over Conlon, Miller, and Fong. 2. Analysis of Dependent Claims 44–46 Claims 44–46 depend, directly or indirectly, from claim 41. We, likewise, determine whether the combination renders obvious claims 44–46, taking into account the arguments made in Petitioner’s Reply Briefs and Dr. Jansen’s Supplemental Rebuttal Declarations. Petitioner contends that dependent claims 44–46, would have been obvious over Conlon, Miller, and Fong, and provides explanation as to how the prior art teaches each claim limitation. Pet. 84–86; Reply 35–39; Pet. Remand Br. 13–14.

    “Patent Owner’s arguments do not undermine Petitioner’s showing. Patent Owner did not specifically challenge Petitioner’s contentions as to the sufficiency of Conlon’s disclosure for claim 1410 in the Patent Owner Response. In the Sur-replies, Patent Owner argues that the claim requires that at least some relationships are created “automatically,” and “these automatic embodiments . . . are represented in this group of claims.” Sur-reply 9. Along these lines, in the additional briefing Patent Owner argues that Conlon does not teach “automatic,” but merely teaches “semi-automatic.” PO Remand Br. 9–10. The crux of Patent Owner’s argument, however, is that the Federal Circuit did not properly construe the limitation, and ignored certain disclosures in the ’433 (and ’680) patent. Id. at 10–11; see Pet. Remand Resp. Br. 1–4; PO Remand Resp. Br. 4–5. The Federal Circuit held that “the dictionary routine claims can be satisfied by mere use of a lexical database, and do not also require the automatic creation of additional definitions.” Appeal Dec. 10. Moreover, the statements from Conlon that Patent Owner relies upon relate to creating a database, not using the database. See id. As discussed above, on remand we are directed to apply the Federal Circuit’s construction. Patent Owner does not explain 10 As discussed in the original Final Written Decisions, Patent Owner raised several arguments that generally applied to all the claims, challenging, for example, the level of ordinary skill in the art, whether Conlon, Miller, and Beckwith were analogous art, and several general arguments relating to Conlon and the motivation to combine Conlon with a DBMS. See Final Dec. 14–23, 25–27. We were not persuaded by Patent Owner’s arguments; the Federal Circuit affirmed, determining that our findings were supported by substantial evidence. Appeal Dec. 14–16. why Petitioner’s contentions are not persuasive in light of the Federal Circuit’s construction of this limitation. In addition, Patent Owner argues in the Sur-replies that “[c]laims 14– 19 are not disclosed by the proffered prior art” and cites to paragraphs 78–83 of the Ranka Rebuttal Declarations. Sur-reply 10. As discussed in the original Final Written Decisions, Patent Owner’s reliance on six paragraphs of Dr. Ranka’s Rebuttal Declarations is an improper incorporation by reference, as Patent Owner did not discuss that testimony or further elaborate on these arguments in the Sur-replies. 37 C.F.R. § 42.6(a)(3); Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 9–10 (PTAB Aug. 29, 2014) (informative); see, e.g., Final Dec. 37–39, 45, 48–50, 52. Therefore, we will not consider arguments that are not made in the Sur-replies, but are instead improperly incorporated by reference to the cited paragraphs in Dr. Ranka’s Rebuttal Declarations. Accordingly, after considering the evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that Conlon teaches limitation [14.3], and that claim 14 would have been obvious over Conlon.” slip op. at 21

    “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

  • Expert testimonyPatent owner expert creditedDecided for patent owner

    “We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

    “understanding of a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”). Graham, , 383 U.S. at 17–18. Petitioner argued that a person of ordinary skill in the art would have had a “at least a four-year degree in electrical engineering, chemical engineering, physics, or material science or a closely related field and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies. Additional education could substitute for professional experience and vice versa.” Pet. 11 (citing Ex 1003 ¶ 69). Patent Owner did not dispute this proposed definition prior to institution. See generally Prelim. Resp. In our Decision on Institution, we adopted Petitioner’s proposal. After institution, Patent Owner asserted a slightly different definition of a POSITA, namely someone who “would have possessed at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” Resp. 17. Relevant graduate education could substitute for the professional work experience. Id. Upon review of the full record, we see no reason to modify, and we thus maintain, the definition of a POSITA applied in our Decision on Institution. We also determine that our decision would be the same under either of the parties’ proposed definitions.” slip op. at 14

    “February 24, 2025, the District Court ordered all deadlines and hearings stayed pending further order of the court. See Ex. 1066. The District Court’s order notes that Patent Owner asserts 8 patents in the litigation, that IPRs have been instituted on 4 of those patents covering 10 of the 14 claims asserted in the litigation, and that further consideration of a stay will depend upon whether IPRs are instituted on patents including the 4 remaining claims. Id. at 1, 3. The District Court also ordered the parties to update their positions on a stay within one week of a decision on institution. It is unclear if, and when, a new trial date would be set. Thus, factors 1 and 2 weigh against exercising discretion to deny institution. The subject matter of the challenged claims is closely related to the subject matter of the claims of the patents in the previously instituted IPRs and the remaining pending petitions, as evidenced by the overlap of the asserted references and arguments advanced in these cases. As detailed in the substantive sections of this Decision, the Petition meets the standard for institution, i.e., there is a reasonable likelihood that Petitioner would prevail with respect to at least 1 of the claims challenged in the Petition. Under Fintiv factor 6, these circumstances weigh against exercising discretion to deny institution. In view of these circumstances, we determine that factors 1, 2, and 6 strongly weigh against exercising discretion to deny institution.” slip op. at 5

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

    “c) Claim 1 Analysis Petitioner has demonstrated that, contrary to Patent Owner’s arguments, Yerazunis discloses write protecting a segment of the buffer. Yerazunis explicitly states that “[upon] a firing event, specified frame data associated with that firing event both before and after the event is preserved and cannot be overwritten as a result of further use of the gun or subsequent of memory to a second portion of memory to avoid overwriting the data in the first portion of memory upon the occurrence of a second trigger event is an effective approach to designating the first portion of memory as write protected. As Petitioner points out, an ordinarily skilled artisan would have understood from Yerazunis that retrieving video data for gun firing events necessitates the ability to locate the relevant video data within the buffer and that using pointers in a table to index the data allows for its later retrieval. Pet. 25 (citing Ex. 1062, Sarhan Decl. ¶ 372). We find unavailing Patent Owner’s argument that Yerazunis’ disclosure of a purge button to erase the contents of the circular buffer is further evidence that that entire buffer contents is protected and unprotected as a whole. Prelim. Resp. 30 (citing Ex. 1017, 9:47–51). It is unclear how providing an “optional” purge feature that erases the contents of the circular buffer and captured still images a “user does not desire to retain” supports Patent Owner’s argument that Yerazunis does not disclose write protecting segments of the buffer associated with a trigger event. Ex. 1017, 9:49–53. Inclusion of this feature further supports Petitioner’s argument, as the segments of a circular buffer associated with an event are not overwritten, unless the user invokes the purge feature to erase the contents of the circular buffer. Also unavailing is Patent Owner’s argument that video data preservation in Yerazunis “is a step that occurs after, not as part of, the step of ‘continu[ing] to record for a brief interval.’” See Prelim. Resp. 30–31. Claim 1 is an apparatus claim and does not recite “continuing to record for a brief interval.” See Ex. 1060, 12:19–47 (claim 1). Claim 1 recites “a computer processor configured to . . . continuing to record the sensor data in designated for saving.” Ex. 1060, 12:22, 34–36. Yerazunis discloses that upon detection of a trigger event a predetermined number of frames, e.g., 2 frames, are stored in successive frame locations within the circular buffer. Ex. 1017, 8:26–32; 12:14–28. Yerazunis further discloses that “any desired percentage of frames may be captured prior to or after the trigger event by specifying how many frames are to be captured and stored after the trigger event.” Id. at 8:39–42.” slip op. at 21
