“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.

“Level of Ordinary Skill in the Art Based on the testimony of the parties’ witnesses, we determine that a person of ordinary skill in the art would have had a bachelor’s degree in paper science and engineering, chemical engineering, process engineering, mechanical engineering, or a related degree, with three to five years of experience in paperboard manufacturing, or a master’s degree in paper science and engineering, chemical engineering, process engineering, or mechanical engineering, or a similar field with a specialization in paperboard manufacturing. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26. We find that the level of ordinary skill in the art, as articulated above, is consistent with the level of technical understanding and competence reflected in the ’142 Patent Specification and the asserted prior art references.” slip op. at 10

“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. Here, we find no claim language, lexicography, or disclaimer in the ’142 Patent or its file history that would support defining a “hot-hard calender” as requiring that only one of the two rollers be heated to an elevated temperature.” slip op. at 12

“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. Cir. 2003)). “[S]uch an overlap creates a presumption of obviousness, and . . . the burden of production falls upon the patentee to come forward with pertinent evidence that the overlapping range would not have been obvious in light of the prior art.” Id.

“III. ANALYSIS A. Level of Ordinary Skill in the Art The level of ordinary skill in the art at the time of the invention is a factual determination that provides a primary guarantee of objectivity in an obviousness analysis. Al-Site Corp. v. VSI Int’l Inc., 174 F.3d 1308, 1324 (Fed. Cir. 1999) (citing Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991)). Based on Petitioner’s contention, which Patent Owner does not dispute, we find that a person of ordinary skill in the art would have had a bachelor’s degree in mechanical engineering, chemical engineering, or a related field, and two years of experience in the research, design, or development of POCs and related hardware, software, and firmware. Compare Pet. 21, with Resp. 11. Our finding is supported by Dr. Knaebel’s testimony. Ex. 1003 ¶¶ 226–228. The level of ordinary skill in the art, as defined above, appears consistent with the disclosures of the asserted prior art and the written description of the invention provided in the ’614 patent.” slip op. at 8

“Deane thus teaches that adsorbent housing 602 and adsorbent bed columns 508a, 508b—the asserted separation cartridge—are part of an apparatus that rests on a support surface such as a table or floor. Based on Deane’s disclosure, we find persuasive Patent Owner’s contention, and Patent Owner’s witness’s opinion, that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) cannot be removed from the receptacle by movement of the separation cartridge vertically downward. Resp. 37–38; Ex. 2001 ¶¶ 118–131. Neither Petitioner nor Petitioner’s witness, Dr. Knaebel, points to any evidence of record showing that one of ordinary skill in the art would have understood that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) could be removed from manifold 512 (receptacle) by moving housing 602/adsorbent bed columns 508a, 508b (separation cartridge) downward when the apparatus is resting on a table or floor, as taught by Deane. Pet. 42–43; Ex. 1078 ¶¶ 121–161. Petitioner fails to show that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) could be removed from the receptacle by movement of the separation cartridge in the downward (second) direction, as required by the removal direction limitation of claim 1. Petitioner, therefore, does not establish unpatentability under its axial movement theory.” slip op. at 26
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“Giving effect to “by movement relative to the receptacle,” when interpreting this phrase in combination with “a separation cartridge selectively removable from a receptacle,” requires that the separation cartridge is removable from the receptacle by movement of the separation cartridge itself. Interpreting the removal direction limitation to encompass a stationary separation cartridge, as Petitioner proposes, would render “by movement relative to the receptacle” superfluous. Specifically, Petitioner’s interpretation of “relative movement” does not accord weight to the recitation “movement relative to the receptacle,” which requires something other than the receptacle—the separation cartridge—to move in order for movement to occur with reference to or in comparison with the receptacle. Petitioner’s interpretation of “relative movement” as permitting removal of the separation cartridge from the receptacle when the separation cartridge remains stationary, is inconsistent with the plain language of removal direction limitation as a whole. The plain language of the removal direction limitation indicates that the separation cartridge must be removable from the receptacle by movement of the separation cartridge in a specified (first) direction. Claim 1 defines the first direction as a direction opposite the (second) direction in which the inlet and outlet are oriented. The plain language of the removal direction limitation, therefore, requires that the separation cartridge is removable from a receptacle by movement of the separation cartridge in comparison to the receptacle in a direction opposite the direction in which the separation cartridge’s inlet and outlet are oriented.” slip op. at 15

“(a) Untimely new theory of unpatentability We agree with Patent Owner (Sur-Reply 4) that Petitioner’s relative movement theory is an impermissible new theory of unpatentability improperly presented for the first time in the Reply. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1008–09 (Fed. Cir. 2023) (A petitioner may not raise in a reply “‘an entirely new theory of prima facie obviousness absent from the petition,’ even if the new theory is responsive to the patent owner’s response or the Board’s institution decision.”) (quoting Wasica Finance GmbH v.

Cir. 2019) (“We conclude that the Board did not abuse its discretion in . . . disregarding its [petitioner’s] new theory first raised in reply.”). Petitioner does not present the relative movement theory in the Petition, and instead presents it for the first time in the Reply. Pet. 42–43. Far from fairly meeting any argument introduced by Patent Owner in the Response, this new theory unfairly changes the thrust of the challenge.” slip op. at 27

Q And how exactly, in your understanding as a person of skill, does the scrambler generate that plurality? . . . THE WITNESS: . . . So the person of ordinary skill in the art would understand that these are multiple arrows here indicated explicitly to suggest parallel operations of the ECC engines. And for them to have parallel operations, a person of ordinary skill in the art would assume that they are receiving inputs at the same time, and the scrambler would, for example, do that by sending descrambled data to different engines at a time, one at a time. . . . Q So how does the scrambler’s function of intrachannel rearrangement generate multiple data streams? . . . THE WITNESS: Once it’s descrambled on a per-block basis, it simply sends that block to a given engine, ECC engine. . . . Q Can the scrambler send out multiple data streams in parallel at the same time? A If it’s designed like that, yes. Ex. 2024, 32:24–34:7 (objections and witness’s false start omitted). Q So describe for me how in Figure 8 that would work for your analysis where the scrambler receiving the data from the multiplexer would then generate the plurality of partially decoded data streams. A Right. Figure 8. So if it receives a long string of data that has already been processed by the 104 unit, it would perform intra- -- intrachannel, if you will, intrablock disarrangement of data.

Accordingly, Petitioner submits that a POSITA would be apprised that “the amount of light emitted from the light-emitting element 310 reaching the cup-shaped sidewall of the package…can be reduced, so that deterioration of the package can be prevented.” Id. (citing Ex. 1007 ¶ 42; Ex. 1026, 14:13–20).

Id. (citing Ex. 1014 ¶¶ 35, 36).

“1. “interactive user interface” In the Decision on Institution, we construed the term “interactive user interface” (“IUI”) as “a display with which a user may interact to result in the portable device taking action responsively.” Inst. Dec. 19. The parties have presented additional arguments in additional briefing on the term’s construction, which we have further considered, and, as discussed below, we modify the interpretation of the term. See PO Resp. 7–16; Pet. Reply 1–3. a. Petitioner’s Assertions In the Petition, Petitioner asserts that the term “interactive user interface” should be interpreted as “a display with which a user may interact to result in the computer taking action responsively.” Pet. 14. Petitioner argues that this proposed interpretation is consistent with the plain and ordinary meaning of the term. Id. at 13. Petitioner also contends that although the term “interactive user interface” is not used in the ’969 patent specification, the specification consistently describes the terminal output component as a “display mechanism,” and the interactive user interface is presented on the terminal output component in the claims. Id. (citing Ex. 1001, 4:40). Petitioner contends that a number of displays in the ’969 patent respond to text inputs from an input component to elicit a responsive action, and refers to an example of the input of registration information in screen 515 in Figure 5, where, if the input is successful, follow-up screen 517 is produced, but otherwise there is an error message. Id. at 13–14 (citing Ex. 1001, 9:52–54, 7:53–56). In its Reply, Petitioner asserts that the ordinary meaning of the term “interactive user interface” is “a presentation (display) with which a user may interact to result in the computer (portable device) taking action responsively.” Pet. Reply 1. This is similar to the construction that Petitioner previously proposed in the Petition, however, Petitioner now proposes that the “computer” can be considered to be a “portable device,” and a “display” can also be considered to be a “presentation. See Pet.14. According to Petitioner, the claims require that the interactive user interface be presented on the terminal output component. Pet. Reply 1. Petitioner argues that the specification describes that it is a portable device that responds to user interaction with the IUI, such as the interaction with a login screen text box. Id. at 2 (citing Ex. 1046, 52:11–55:13; Ex. 1001, 7:55–56). Petitioner asserts that the claims require that it is the portable device that responds to user interaction, with the “fourth program code” executing in response to user interaction with the interactive user interface. Id. Petitioner compares the claim of the parent ’047 patent, which was narrowed to refer to “the interactive user interface is configured to enable the user to cause the portable device processor to execute program code stored on the portable device memory,” to the claims here. Id. Petitioner also asserts that “‘[p]resentation’ is used and described in the ’969 patent as corresponding to a ‘display.’” Id. at 1.” slip op. at 13

“In view of our analysis below, we need not construe expressly any claim language to resolve the parties’ patentability dispute. The Petition’s first challenge asserts obviousness of claims 1, 2, 7, 8, 9, and 14 over Picard and Ishihara. Pet. 18–39. As explained in greater detail below in Section III.B.3, this challenge rests on a contention that it would have been obvious to modify Picard to use telecentric optics like those taught in Ishihara. Id. at 32–38. With respect to the challenge of claims 1, 2, 7, 8, 9, and 14 over Picard and Ishihara, the Petition does not explain any theory of unpatentability that does not rely on the assertion that it would have been obvious to modify Picard with telecentric optics based on Ishihara. Id. at 18–39. Thus, the merits of this challenge inextricably depend on whether Petitioner has demonstrated adequately that it would have been obvious to modify Picard with telecentic optics based on Ishihara.

Therefore, Petitioner’s challenge of claims 1, 2, 7, 8, 9, and 14 over Picard and Ishihara fails for reasons unrelated to claim construction.” slip op. at 9

“have foreseen Patent Owner’s argument does not justify its insufficient explanation and lack of evidence in the Petition. As Patent Owner argues, its ITC brief, filed approximately a month before the Petition was filed, provided effective notice of Patent Owner’s position that there would have been issues using Gmitro’s fiber-optic bundle to carry the plurality of light beams used in Tiziani. Id. Moreover, even without such express notice, Petitioner should have recognized the requirement that its Petition must “identif[y], in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3).

The Petition fails to meet these requirements with respect to its assertion that a person of ordinary skill in the art would have had a reasonable expectation of success in combining Gmitro’s fiber-optic bundle with Tiziani’s confocal imaging system and microlens array. It is “improper for a reply to present new evidence (including new expert testimony) that could have been presented in a prior filing.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), 74– 75 (citing Genzyme Therapeutic Prods.
