“of whether we exercise our discretion to deny institution under 35 U.S.C. § 314(a). Rather, when considering the Fintiv factors, we “take[] a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review.” Fintiv at 6. Here, factors one and six are neutral, factors two and three weigh against discretionary denial, and factors four and five favor denial. We assign less weight to the existence of an overlap in asserted claims and prior art, in view of there being no trial date scheduled in the District Court case and no persuasive evidence that the court’s trial date would be expected to be significantly before the due date of our Final Written Decision. Therefore, after weighing all of the factors, we determine that the facts in this case that weigh against exercising discretion outweigh the facts that favor exercising discretion. Accordingly, we decline to exercise our discretion to deny institution under § 314(a).” slip op. at 13

Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id.

Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied.

First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89.

“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.

“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.

“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.

(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.

“Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals. These two facts provide together a proper reason to limit the claims in this way.”); Phillips v. AWH Corp., 415 F.3d 1303, 1312–1317 (Fed. Cir. 2005) (en banc) (“[T]he specification may reveal an intentional disclaimer, or disavowal, of claim scope by the inventor.

“Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim.

Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application).
