“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.

“Mr. Kunselman, neither of whom supports his opinion with objective evidence. Pet. 35 (citing Ex. 1003 ¶ 20); PO Resp. 11–12 (referring to Mr. Kunselman’s opinion appearing at Ex. 2012 ¶¶ 15–21); Reply 20–21 (citing Ex. 1003 ¶ 20; Ex. 1061 ¶¶ 11–13). The level of skill is determined “in the art to which the claimed invention pertains,” 35 U.S.C. § 103, and neither party identifies that art explicitly. The Specification describes the field of invention as follows: “This invention is related to the field of automotive chassis design and more specifically to the area of interchangeable chassis for use with many models of vehicles.” Ex. 1001, 1:17–19. The Specification repeatedly refers to the chassis as having “universal” characteristics. Id. at Title, passim. The Specification also describes an advantage of its chassis as having “an ability to adapt to different bodies and body styles,” id. at 2:17–21, and criticizes prior art chassis designs that “are not readily adaptable to a wide variety of vehicles without forcing major and expensive redesign work for each vehicle,” id. at 1:29–33. Claims 43 and 44 expressly require that the claimed chassis be “universally adapted” for more than one type of vehicular configuration. Id. at 16:40–17:19. Based on these descriptions of the chassis and the express requirements in at least some of the claims at issue, we determine that the art to which the claimed invention pertains is the design of interchangeable chassis for use with many models of vehicles. We consider Mr. Kunselman’s testimony on the level of ordinary skill to be tied more closely to this relevant art of designing a chassis for use with many models of vehicles. Accordingly, we adopt Patent Owner’s definition of the level of ordinary skill for purposes of this Decision and evaluate priority of invention and obviousness from that perspective. We note that both Mr. Parker and Mr. Kunselman possess such a skill level. Ex. 1003 ¶¶ 6–13; Ex. 2012 ¶¶ 4–9.” slip op. at 7

“in claims 9 and 32–43 when it states that: “During attachment of the central backbone between the front and rear structures, the operational components (e.g., quill shaft for conventional vehicle, battery for electric or hybrid vehicle), are suitably coupled or connected.” Ex. 1006 ¶ 43. Based on this disclosure in the ’490 App, Mr. Kunselman opines without citing any objective evidence in support that: “The only suitable connection it could be is a wire and a cable. No other option has ever been used, not a metal tab, buss bar, or printed circuit board.” Ex. 2012 ¶ 75 (citing Ex. 1006 ¶ 43). Because the testimony cited by the parties on this issue leads to stalemate, we examine other aspects of the ’490 App and other evidence. Figure 16 of the ’490 App, reproduced at right, illustrates batteries located in a central structure that connects one end of a chassis with a generator to the other end of the chassis with an electric motor. Mr. Parker testifies that components such as wires connecting batteries were “conventional components” that were “well known” and “found in almost all vehicles decades before the ’163 patent was filed.” Ex. 1003 ¶ 61. Figure 16 illustrates batteries within the central spine of the plug-in hybrid chassis, along with the generator on one end, which would charge those batteries, and an e-motor on the other end, which would be powered by those batteries. Ex. 1006, Figure 16. Both experts agree that an electrical wire is a well known type of electrical connection that would be suitable. Ex. 1003 ¶ 61, Ex. 2012 ¶ 75. On the record before us, we determine that Figure 16 in the ’490 App, along with the description of batteries being “suitably coupled and connected” constitutes a description of an electrical connection spanning the batteries within the central spine and to components connected to opposite ends of that spine. This is especially true given the high degree of skill possessed by an ordinarily skilled artisan. Such an artisan would have no trouble recognizing that the ’490 App described using wire to connect batteries located within the central structure and that those wires would span the entire central spine. Ex. 2012 ¶ 75. For this reason, we determine that the wire features of claims 9, 32–37, and 43 are supported by the description in the ’490 App.” slip op. at 12
- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for petitioner
“lexicographically define “chassis” but merely describes “another aspect of the universal chassis apparatus.” Reply 17–18. We agree. To act as its own lexicographer, a patentee must “clearly set forth a definition of the disputed claim term” other than its plain and ordinary meaning. CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366 (Fed.Cir.2002). It is not enough for a patentee to simply disclose a single embodiment or use a word in the same manner in all embodiments, the patentee must “clearly express an intent” to redefine the term. Helmsderfer v. Bobrick Washroom Equip., Inc., 527 F.3d 1379, 1381 (Fed.Cir.2008); see also Kara Tech. Inc. v. Stamps.com, 582 F.3d 1341, 1347–48 (Fed.Cir.2009). At most, we understand the passage quoted by Patent Owner to be describing aspects of the “universal chassis apparatus” rather than providing a lexicographical definition of “chassis.” Petitioner also contends that an ordinarily skilled artisan would understand that “chassis” generally refers to the supporting structure or frame upon which the vehicle’s body, drive train, and suspension components are mounted. Reply 18 (citing Ex. 1003 ¶ 31). Petitioner notes that such an understanding is consistent with the definitions of “chassis” provided in two automotive industry dictionaries, one of which is provided by Patent Owner. Id. at 18–19 (citing Ex. 2024;5 Ex. 1063, 45:4–46:2, 46:20–47:14, 52:15–24; Ex. 1061, ¶ 25); see also Ex. 1052, 3 (defining “chassis” as the “[s]tructural lower part of a vehicle to which the running 5 Exhibit 2024 is an excerpt of a 1993 publication entitled “Auto Dictionary” in which “chassis” is defined as follows: “Lower structure of a vehicle to which the running gear and body are attached. On older cars, the chassis was a separate part of the vehicle with its own frame but, today, it is usually an integral part of the body structure.” Ex. 2024, 3. gear6 and body is attached.”). Mr. Kunselman testifies that “a variety of possible definitions for a chassis” exist. Ex. 1063, 74:12–14. Petitioner also points out that Patent Owner’s proffered definition for “chassis” conflicts with the Abstract of the ’163 patent, which indicates that “other components” including the suspension are attached to—and therefore separate from—a “vehicle chassis.” Reply 19 (citing Ex. 1001, Abstract, Ex. 1061 ¶ 26). Based on our review of the entire record, we conclude that “chassis” is neither precisely defined in the Specification nor understood by an ordinarily skilled artisan to have a precise universally agreed upon definition. Rather, “chassis” refers generally to the supporting structure or frame upon which the vehicle’s body, drive train, and suspension components are mounted.” slip op. at 22

“Patent Owner’s argument is not persuasive for at least three reasons. First, claims 2 and 27 merely require that the backbone have two sections or segments that together define “a substantially T-shape as viewed from above.” Ex. 1001, 13:41–44 (claim 2), 15:15–24 (claim 27). Even with Brandt’s heel plate 40 positioned between the compartments holding battery units 24 and 28, we consider the combination of Brandt’s two compartments to be arranged in “a substantially T-shape as viewed from above” as recited in claims 2 and 27. Additionally, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981) (citations omitted). Third, both Greil and Brandt describe locating batteries in the lower central portion of a vehicle. Ex. 1016, ¶ 38, Figure 5; Ex. 1018 ¶¶ 21– 22, Figure 1. Brandt explicitly suggests arranging batteries in a T-shape configuration. Ex. 1018 ¶¶ 21–22, Figure 1. We conclude that Petitioner has proven by a preponderance of evidence that the combination of Greil and Brandt renders claims 2, 4, and 27–31 unpatentable as obvious.” slip op. at 30

“more than merely “selecting” times. Petitioner offers no explanation how Dr. Ikelle’s testimony that “indexed” should be construed broadly to mean “selected,” Ex. 2002, 184:8–11, would be consistent with the rest of the limitation that requires enabling separate identification of events originating from different sources. Patent Owner’s proposed construction, however, is unduly narrow to the extent it requires recording. As explained in the passage cited by Patent Owner, recording the signal and indexing are two separate aspects of the process involved in the ’981 patent. Ex. 1001, 5:62–67 (“A recording is made of the signal . . . that is indexed to a known time reference with respect to time of firing of the first source) (emphases added). The ’981 patent demonstrates that the term “indexed” is used in the “indexed” limitation according to one of its ordinary meanings that one thing is arranged in reference to another. Id.; see also id. at 6:66–7:1 (“[A] time of firing of each source with respect to a time index” is shown in Figure 4.), 8:33–40 (“[W]hen time is indexed with respect to the firing time of source A,” source B events are not coherent between firing sequences.).” slip op. at 9

“Although a prior art reference may anticipate when the claim limitations not expressly found in that reference are inherent in it, inherency requires that “the prior art necessarily functions in accordance with, or includes, the claimed limitations, it anticipates.” In re Cruciferous Sprout Litig., 301 F.3d 1343, 1349 (Fed. Cir. 2002). Here, Petitioner’s arguments and evidence fail to persuade us that de Kok disclosure of suppressing random noise inherently includes determining trace to trace coherence. Merely demonstrating a step may be done is not sufficient to show that step is inherently anticipated. Accordingly, based on the arguments and evidence submitted, we find Petitioner has failed to demonstrate, by a preponderance of the evidence, that de Kok anticipates claims 12 and 17. Similarly, because claims 13–15 ultimately depend from claim 12, we find Petitioner has failed to demonstrate, by a preponderance of the evidence, that de Kok anticipates claims 13–15.” slip op. at 19

“The relevant passages cited by both parties demonstrate that Beasley distinguishes between alternating and concurrent firings. See, e.g., Ex. 1004, 7:52–63. Although Herkenhoff states that the concurrent disclosure in Beasley means “exactly concurrently,” Patent Owner has not pointed to any clear disclosure in Beasley itself indicating “concurrently” should be understood as excluding any amount of time delay. Petitioner, however, has pointed to multiple references where Beasley explains that sources may be fired “simultaneously or nearly simultaneously.” Pet. Reply 15 (citing Ex. 1004, 8:46–47); Pet. 47 (quoting Ex. 1004, 1:19–25 (“The present invention, in certain aspects, is directed to seismic survey systems and methods in which two or more seismic sources are fired simultaneously, or significantly close together temporally . . . .”)); see also Ex. 1004, 1:47–51, 8:44–47, 9:5–10, 12:26–29. Moreover, claim 1 of the ’655 patent, which Patent Owner asserts claims the “first embodiment” of the ’981 patent, recites a method including the step of “substantially simultaneously launching a first acoustic wavefield,” from the leading source, “the first wavefield being characterized by a first unique code and launching a second acoustic wavefield” from the trailing source, “the second acoustic wavefield being characterized by a second unique code.” Ex. 2009, 6:46–53.
