“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.

“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.

“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.

“Petitioner fails to show that the full scope of claim 9 of Seet is described in the Seet provisional.

Such a statement provides a clear definition of the term “media” that includes video, software, and pictures, in addition to audio. In addition to the express definition, Seet elsewhere indicates that its media includes video and other non-audio signals and databases.

Accordingly, the use of media in claim 9 for its claimed “media content database” and “media stream[s]” also includes both audio and non-audio media. The disclosure of the Seet provisional, however, is more limited and defines the term media exclusively as audio. Ex. 1019, 4 (“Media will be defined as any streaming audio source in any form, be it radio, television, cable, satellite, internet stream, or the like.”).

“2. Reasons to Combine Petitioner contends that it would have been obvious to modify Nguyen’s adapter in two ways. Pet. 54. First, Petitioner asserts it would have been obvious to include “optical-fiber connectors that employ handles configured to remotely release connectors from the adapter” by replacing Nguyen’s connectors with Lee’s connectors. Pet. 54–56 (citing Ex. 1003 ¶¶ 289–295). Second, Petitioner asserts it would have been obvious to include “a transverse wall that includes slots halfway between two ends of the adapter and sleeve holders that employ sockets to mate with cylindrically-shaped ferrules” by replacing Nguyen’s wall with Lee’s sleeve holders. Pet. 54, 56 (citing Ex. 1003 ¶¶ 296–302). Petitioner provides several reasons for the first modification, including a desire for convenience, tightly packed fiber optic ferrules, ease of maintenance, and scalability. Pet. 54 (citing Ex. 1003 ¶¶ 289–290). According to Petitioner, these goals would be served because “Lee’s handle allows a user to disengage the latch arm further from the adapter” whereas “[t]he latch arms of Nguyen require a user to be closer to the adapter.” Id.

Petitioner also provides reasons for the second modification, asserting that “Lee’s sleeve holders are easy to maintain because they are removable, able to snap into place, and coordinate with dust caps to maintain cleanliness, as opposed to Nguyen’s immobile wall.” Pet. 56 (citing Ex. 1003 ¶ 297). According to Petitioner, “a POSITA would have been motivated to modify Nguyen’s adapter to incorporate Lee’s sleeve holders and slots to provide a system that is easier to maintain.” Id. (citing Ex. 1003 ¶¶ 298–299). We find that Petitioner’s asserted rationale for modifying Nguyen in view of Lee is adequate for purposes of institution.” slip op. at 20

“Although Petitioner has asserted the absence of specific supporting disclosure for claims 1, 15, and 18 from the ’780, ’317, and ’977 applications and the ’155, ’587, ’601, ’977, and ’753 provisional applications, the burden to show an effective filing date (or dates) of the challenged claims prior to April 22, 2010 falls on Patent Owner here because Petitioner has asserted prior art references with earlier effective dates. In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1376 (Fed. Cir. 2016) (In an inter partes review, “a patentee bears the burden of establishing that its claimed invention is entitled to an earlier priority date than an asserted prior art reference.”). An earlier effective filing date is not presumed because, as shown in the above figure, the ’783 application is a continuation-in-part to each of the ’780, ’317, and ’977 applications that have filing dates earlier than April 22, 2010. See PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1305 (Fed. Cir. 2008) (“When neither the PTO nor the Board has previously considered priority, there is simply no reason to presume that claims in a [continuation-in-part] application are entitled to the effective filing date of an earlier filed application.”). On this record, and in the absence of the development of any contrary argument, we find that Petitioner has demonstrated sufficiently for institution that each of the asserted references are prior art to the challenged claims.

More particularly, Petitioner argues that Adest discloses the limitations of claims 6, but to the extent there is a dispute that Adest discloses the “watchdog unit” limitation [6A], a person of ordinary skill in the art would have been motivated to combine the watchdog apparatus taught by Kronberg with the solar power system taught by Adest to monitor communications between signal mechanism 420 and power modules 405 of Adest. Id. at 32 (citing Ex. 1002 ¶ 127). Petitioner further argues that the watchdog taught by Kronberg was a well-known technique for detecting malfunctions at the time of the invention, and would have been one of a number of solutions for detecting the absence of a periodic signal. Id. (citing Ex. 1002 ¶¶ 128–129; Ex. 1009, 1269). Petitioner further argues that Kronberg “suggests that its watchdog apparatus is to be used to provide ‘automatic shutdown of critical devices in case of failure,’” consistent with Adest’s objective of shutting down a power generating facility when a transmitter fails to send a communication because of, for example, a fire or theft of a photovoltaic module.

Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). Claims subject to 35 U.S.C. § 112 ¶ 6 are construed in a “two-step process,” whereby we “first identify the claimed function,” and then “determine what structure, if any, disclosed in the specification corresponds to the claimed function.” Id. at 1351. Accordingly, our rules require that the Petition “identify the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” 37 C.F.R. § 42.104(b)(3). Further, “the corresponding structure for a § 112 ¶ 6 claim for a computer-implemented function is the algorithm disclosed in the specification” Aristocrat Techs. Austl. Pty Ltd. v.

Federal Circuit precedent requires disclosure of an algorithm in the specification for any computer-implemented function beyond “basic functions of a microprocessor.” See EON Corp.

All other computer implemented functions require disclosure of an algorithm.”). Petitioner does not identify any portion of the ’218 patent specification that describes corresponding structure for performing the claimed function of “poll[ing] the central controller to determine if an interruption of the communication is transient.” See Pet. 39.
