“Exhibits 1013 and 1014 are also not admissible as expert testimony because Mr. Wirén is not “qualified as an expert by knowledge, skill, experience, training, or education.” Fed. R. Evid. 703. “To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art. Without that skill, the witness’ opinions are neither relevant nor reliable.” Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–77 (Fed. Cir. 2022). Mr. Wirén does not meet our definition of a person of ordinary skill in the art. See Section II.B, supra. That definition is based on the undisputed testimony of Messrs. Zotterman and Klass. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26. Although Mr. Wirén has a Master’s of Science in chemical engineering, he lacks any experience or specialization in paperboard manufacturing. Ex. 2011, 12:1–10, 19:6–25, 20:2–7. We therefore agree with Patent Owner that Exhibits 1013 and 1014 are the testimony of Mr. Wirén and should be excluded from evidence because Mr. Wirén is not a person of ordinary skill in the relevant art.

“A claim construction that excludes a particular element is viewed as a “negative limitation.” Ethicon LLC v. Intuitive Surgical, Inc., 847 Fed. App’x 901, 907 (Fed. Cir. Mar. 15, 2021). “[S]uch exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Id. (citing Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed. Cir. 2003); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366–67 (Fed.

Cir. 2014). “To act as its own lexicographer, a patentee must ‘clearly set forth a definition of the disputed claim term,’ and ‘clearly express an intent to define the term.’” Id. (citing Thorner, 669 F.3d at 1365). Similarly, disclaimer or disavowal requires that the specification or prosecution history demonstrate that the invention does not include a particular feature. Id.

“a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v. Hospira, Inc., 946 F.3d 1333, 1341 (Fed. Cir. 2020) (citing In re Peterson, 315 F.3d 1325, 1329 (Fed.

During prosecution of the parent application to the ’422 patent, Patent Owner stated, inter alia, that “a person of ordinary skill in the art would understand that the width of a cassette is simply the width of the cassettes from side to side and not some other ‘dimension’ such as the number of receptables or the like.” Ex. 1002, 187. Patent Owner further stated that it disagreed with the Examiner’s statement that paragraph 15 of the specification6 defines width in terms of the number of receptacles and that such a definition of width makes no sense in view of other claims where the standard with is defined in terms of a width of front edge of a tray on which the cassettes are secured.

“Owner’s challenge to Petitioner’s Fukui-based grounds is whether, in Fukui, a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette.11 We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 11 There is no dispute on this record that the term “module” as used in Fukui is analogous to the term “cassette” as used in the ’423 patent. 8:6. Thus, conversion module 20 is recognizable has having a singular system of fiber optic components within its body.” slip op. at 23

“b) Reason to Combine & Expectation of Success As explained earlier, Petitioner asserts that it would have been obvious to improve Zhou’s video stabilization techniques by using the techniques in Cai for using future frames to characterize the video as having zero motion or not. Pet. 36. Patent Owner first argues that neither reference “offers any hint or suggestion of combining such reactive systems to create a proactive stabilization solution.” Prelim. Resp. 17; see also id. at 17–19 (similar). Patent Owner has not offered a claim construction, or otherwise explained, how the claims require a “proactive stabilization solution.” Thus, this argument is unpersuasive. Patent Owner next argues that Zhou and Cai are technically incompatible. Id. at 20–23. In particular, Patent Owner argues that Zhou “uses buffering to adjust stabilization strength,” whereas Cai uses buffering “for trajectory adjustment and distinguishing jitter from zero-motion or lowspeed movements.” Id. at 21–22 (emphasis removed). On this record, however, we are not provided with sufficient technical reasoning explaining how using the buffer for one purpose precludes its use for another purpose. Patent Owner cites its declarant, Dr. Foroosh, but his testimony merely repeats Patent Owner’s arguments without any meaningful elucidation. Id. at 22 (citing Ex. 2001 ¶ 70); 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v. Bytemark, Inc., IPR2022- 00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). On this record, we are shown no technical impediment with using the buffer in Zhou for distinguishing non-zero motion by looking ahead some number of frames, as proposed in the Petition.” slip op. at 12

“5. Conclusion for the Bell & Shi Ground In summary, we determine on this limited record that Petitioner has shown sufficiently that Shi discloses the low-light high-pass parameter of claim 1 and that there would have been a reason to combine Bell and Shi. We adopt Petitioner’s remaining unchallenged assertions regarding claim 1 as our own. We are not persuaded by Patent Owner’s objective indicia analysis, which is lacking a showing of nexus. In conclusion, we determine that Petitioner has demonstrated a reasonable likelihood of success in showing that the subject matter of claim 1 of the ’840 patent would have been obvious in view of Bell and Shi. No issue unique to any of the other claims in this ground is raised at this time.” slip op. at 17

“Looking to the claim language itself, we note that the claim mentions “low-light high-pass parameter” once, in the context of listing it as one of three alternative things covered by the claim. Ex. 1001, 30:35–38. We find the specification of the ’840 patent discusses the low-light high-pass parameter in two paragraphs. Id. at 21:59–22:21. In these passages, the ’840 patent states that the low-light high-pass parameter may be “a parameter that controls the amount/strength of smoothing performed to generate the smoothed trajectory.” Id. at 21:59–61. The parameter may take a value corresponding to the amount of motion blur compensation to be used. Id. at 22:8–21. Thus, the specification states that the low-light high-pass parameter is used to control the amount of motion blur compensation.” slip op. at 8

“Patent Owner then argues that Bell and Shi are incompatible techniques and would not be combined. Prelim. Resp. 19–20. In particular, Patent Owner argues that Bell preemptively adjusts for future motion, whereas Shi reacts only after blur is detected. Id. at 20. On this record, this argument is unpersuasive because Patent Owner has not sufficiently explained the alleged technical incompatibility. Patent Owner’s position relies on the testimony of Dr. Foroosh, but we do not credit his testimony here because it merely mirrors what Patent Owner has argued, without technical explanation. Ex. 2001 ¶ 65; 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight”); Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In contrast, both Bell and Shi look at future frames for motion smoothing. Ex. 1006, 10:10–16 (describing Bell’s “look-ahead buffer”); Ex. 1007, 1:61– 65 (describing Shi’s “use [of] future frames”). Thus, on this record, we are not persuaded that there is a technical incompatibility in the manner Patent Owner alleges.” slip op. at 14
- Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusOther
“Prelim. Resp. 23–31. Patent Owner’s position is underpinned by its evidence purporting to show its “dominant position in the U.S. action camera market,” based on its “HyperSmooth technology” that it asserts “has garnered widespread industry recognition.” See generally id. However, even if we were to accept Patent Owner’s argument that it has a revolutionary and successful product, that does not mean that all claims of its patents would have been non-obvious. For us to give substantial weight to objective indicia of non-obviousness, a proponent must establish a nexus between the evidence and the merits of the claimed invention. ClassCo, Inc., v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” Id. (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)); see also Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010) (“For objective evidence of secondary considerations to be accorded substantial weight, its proponent must establish a nexus between the evidence and the merits of the claimed invention.”) (cleaned up). Patent Owner here has not attempted a nexus analysis in its Preliminary Response. At best, it improperly incorporates by reference a claim chart (Exhibit 2016) served in the related ITC proceeding. Prelim. Resp. 25; 37 C.F.R. § 42.6(a)(3) (“Arguments must not be incorporated by reference from one document into another document.”). Even then, the claim chart appears to admit that claim 1 does not read on Patent Owner’s technology. Ex. 2016, 30.2 On this record, we cannot determine whether, or the extent to which, Patent Owner’s assertions of non-obviousness are due to the claimed invention because of the failure to show nexus to the subject matter of the claims.” slip op. at 16

“52 subcarriers are used while “the DC subcarrier and 11 subcarriers near the edges of the 20 MHZ channel are not used for data transmission” (i.e., are set to zero). Ex. 1014, 2:14–30 (explaining the long training sequence for a conventional 802.11a preamble), 6:11–15. Notably, Jones also teaches that “packet formation block 314 may insert appropriate complex values at unused . . . subcarrier locations in each group of symbols D[k],” and that “any or all of the subcarriers k may be used to transmit data, thereby increasing the data rate.” Id. at 6:15–20 (emphasis added); see also id. at 8:22–24 (teaching that an extended long training sequence “can contain more than 52 non-zero subcarriers”). At this stage, we credit Dr. Buehrer’s testimony that one of ordinary skill in the art would have been motivated to “add[] four subcarriers to 802.11a data and training fields [to] increase[] data rate throughput as taught in . . . Jones,” as this testimony is consistent with Jones’s teachings. Ex. 1005 ¶ 107. In addition, we agree with Petitioner and find that one of ordinary skill in the art extending the long training sequence would want to use the same 52 center subcarriers to maintain backwards compatibility with 802.11a. Pet. 28–29. This is supported by Jones’s teaching of having a long training sequence that “is usable in a process for determining whether the packet is an 802.11a packet or an extended-mode packet.” Ex. 1014, 8:37– 40. Moreover, Jones’s L2 example of an extended long training sequence maintains the same 52 center subcarriers as 802.11a, which also supports this finding. Id. at Fig. 4; Ex. 1005 ¶¶ 96, 113. Thus, up to 11 subcarriers unused in 802.11a could be used for an extended long training sequence. “more than 52 non-zero subcarriers” can be used for an extended long training sequence, which explicitly teaches that only a portion of the 11 subcarriers may be used. Ex. 1014, 6:15–20, 8:22–24. In light of the above teachings, we find that one of ordinary skill in the art would have found it obvious to use only the next 4 nearest to the center of these 11 unused subcarriers. Ex. 1005 ¶ 87. The remaining 7 subcarriers would remain at zero.” slip op. at 15
