    “E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight.

    “B. Level of Ordinary Skill in the Art We consider the asserted ground of unpatentability in view of the understanding of a person of ordinary skill in the art (“POSITA” or “POSA”). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d Relying on the declaration testimony of its expert, Dr. Doolittle, Petitioner contends that an ordinarily skilled artisan for the ’678 patent “would have had an undergraduate degree (i.e., B.S., B.S.E. or the equivalent) in electrical engineering, materials science, physics, or a similar discipline” and “would also have one to two years of experience in the field of LED packaging design.” Pet. 5–6. Petitioner additionally contends that “[m]ore education could substitute for experience, and vice versa.” Id. Petitioner further contends that “[t]his person would have been capable of understanding and applying the teachings of the ’678 patent and the prior-art references discussed herein,” and “[m]oreover, the prior art reflects the level of skill at the time of the claimed invention.” Id. (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); Ex. 1102 ¶¶ 38–42). Patent Owner states that “solely for the purposes of this proceeding, Patent Owner and its technical expert employ the same level of skill in the art as Petitioners.” PO Resp. 24–25.

    “c. Analysis We agree with Petitioner that the “second map image” should be construed as the map image in the second person view. Reply 5. Under Petitioner’s proposed construction, the terms “first” and “second” identify which person view that the map image is within. Id.

    “Here, we disagree with Patent Owner’s argument because it is based on the premise that the second map image is different from the first in a way that is not reflected in the claims. See Section II.C.3 supra. Even if “the claims consistently use the terms ‘first’ and ‘second’ to refer to separate and distinct elements,” A3UM’s first and second map images are separate and distinct elements for at least the reason they are included in separate and distinct views in the interface. See Pet. 63; Reply 5. As discussed in Section II.C.3, the second map image is the map image in the second person view. Here, Petitioner sufficiently shows that A3UM provides the same functionality for each person, including displaying the person in the Faces view with their name within A3UM’s overall user interface. See Pet. 62 (citing Ex. 1003, ¶215; Ex. 1005, 418–420). Patent Owner does not dispute this. See PO Resp.; Sur-reply. For the same reasons why A3UM teaches the “first map image” with respect to a first person view recited in claims 1 and 31, Petitioner has shown that A3UM also teaches the “second map image” in the second person view. See FWD 53–56. In sum, Patent Owner’s arguments are unpersuasive because they are based on an incorrect claim construction, and Petitioner has shown that claims 13 and 45 are unpatentable. 5. Claims 14–16 and 46–48 Apart from the arguments analyzed above, Patent Owner does not present separate arguments directed to the subject matter of claims 14–16 burden to show that the challenged claims are unpatentable. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). We have reviewed Petitioner’s arguments and evidence submitted in connection with the remaining limitations and find them persuasive as they are consistent with and supported by the evidence of record.

    “Yet paragraph 122 of Mr. Lipoff’s declaration merely repeats the Petition’s argument almost verbatim. Compare Ex. 1007 ¶ 122, with Pet. 28. Mr. Lipoff does not add any citation to Avellan or any other source that supports his testimony. See Ex. 1007 ¶ 122. Nor does Mr. Lipoff offer any additional technical reasoning than what is stated in the Petition. Testimony may be entitled to little weight if it merely restates the petition’s unsupported, conclusory assertions without adding supporting evidence or technical reasoning. Xerox Corp. v.

    “We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

    “had “a bachelor’s degree in electrical engineering, computer engineering, or a related discipline, knowledge of the relevant 3GPP standards” and “at least 2 years of experience working in a field involving wireless communications.” Pet. 10 (citing Ex. 1002 ¶¶ 38–40). According to Petitioner, a “person with a different degree but with additional relevant experience could still qualify if the additional experience compensates for the different educational background.” Id. Petitioner also asserts a “person with less than 2 years of experience working in a field involving wireless communications could still qualify if the person has additional education that compensate[s] for their lesser experience.” Id. Patent Owner does not dispute Petitioner’s proposed level of skill. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s formulation of the level of ordinary skill in the art, because it appears consistent with the ’463 Patent Specification and the prior art of record.” slip op. at 8

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)Not reached

    “Petitioner asserts that elements 1[b] and 1[c] constitute a mean-plus- function limitation under 35 U.S.C. § 112(f) and Patent Owner disputes Petitioner’s assertion. See Pet. 5–7; PO Resp. 11–13. As demonstrated below, there is no dispute as to whether the prior art teaches limitations 1[b] and 1[c] under Petitioner’s claim construction. Therefore, we need not address whether 35 U.S.C. § 112 (f) applies. “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.

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

    “We do not agree with Patent Owner’s arguments disputing Petitioner’s backward compatibility rationale for combining the teachings of Yan and Takeda. Patent Owner’s arguments are misplaced because they are premised incorrectly on Takeda’s teachings being limited to 5G NR (i.e., standalone 5G NR), and the proposed combination requiring “mixing standards and behaviors.” To the contrary, Petitioner explicitly asserts that “Takeda states that its teachings are applicable to both 4G and 5G”––i.e., non-standalone 5G. Pet. 14 (citing Ex. 1007 ¶ 239). Likewise, instead of mixing 5G and 4G standards and behaviors as argued by Patent Owner, Petitioner merely proposes retaining Yan’s 4G method of allocating UL channel resources sets with Takeda’s teaching of 5G NR BWPs. See Pet. 14–15. We credit Dr. Roy’s testimony that a person of ordinary skill in the art would have been motivated to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network capability because it is supported by the cited evidence of record. See Ex. 1002 ¶¶ 105, 106 (citing Ex. 1007 ¶ 239; Ex. 1031, 1, 3; Ex. 1033, 5:23–31; Ex. 1034, 10; Ex. 1035, 1, 5; Ex. 1037, 31). Moreover, as pointed out by Petitioner, Dr. Shimony’s deposition testimony regarding the usefulness of backward compatibility and the importance of a non-standalone UE having the ability to communicate over both 4G and 5G standards supports Dr. Roy’s testimony, yet undermines Patent Owner’s arguments. See Ex. 1050, 178:16–182:16; Pet. Reply 14–15. Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network compatibility.10 See Pet. 13–15; KSR, 550 U.S. at 418.” slip op. at 15

    “All other challenged claims require the “generating” and “assembling” operations because they depend from claims 1, 12, or 17. Petitioner does not allege that the additional references—Durante, Ma, Suzuki, Wanamaker, Heikens, Matthews, or Wilsher—teach or suggest the “temporal sequence of screen captures” recited in claim 1. Rather, Petitioner’s reasoning in the challenges to the dependent claims pertaining to the screen captures mirror the rationale presented in the independent claim. See, e.g., Pet. 25 (arguing that Avellan’s screen captures correspond to the video content in the challenge to claim 2), 26–27 (arguing that Avellan obtains screen captures from a playback of a video on the webpage in the challenge to claim 4). Petitioner’s argument that Avellan teaches or suggests these operations in the grounds based on obviousness under 35 U.S.C. § 103 depend on the reasoning and insufficiently supported characterizations of Avellan in the challenges based on 35 U.S.C. § 102, as discussed above. See Pet. 40–60. grounds based on anticipation under 35 U.S.C. § 102 or teaches or suggests these operations in the grounds based on obviousness under 35 U.S.C. § 103, Petitioner has not met its burden to show that any challenged claim is unpatentable as anticipated by Avellan or obvious over any of the combinations of Avellan and the other cited references.” slip op. at 15
