    “appears to be generally consistent with the level of skill presented in the cited prior art. See generally, e.g., Exs. 1005–1008; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

However, as at institution, we reject the portion of Petitioner’s proposed definition that includes having “access to other individuals with that knowledge and experience,” as not reflecting the individual level of skill of a given skilled artisan. See, e.g., Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986) (holding that “[t]he person of ordinary skill is a hypothetical person who is presumed to be aware of all the pertinent prior art.”) (emphasis added, footnotes omitted); but see Indivior Inc. v. Dr. Reddy’s Labys., S.A., 930 F.3d 1325, 1343 (Fed. Cir. 2019) (no clear error in determination that “a person of ordinary skill . . . ‘would be on a team with an engineer or scientist . . . .’”). Consequently, we find the person of ordinary skill in the art was a person who had a Ph.D. in immunology, molecular biology, cellular biology, or a similar field, or an M.D. with similar experience, and had at least five years of experience with antibodies and antibody engineering.” slip op. at 11

    “At the outset, we note that the claim language requires only that “the first seat and the second seat” be arranged in an inline descending configuration, not that the seat’s mounting points or other physical connections be so arranged. Ex. 1010, 17:31–33. Baby Jogger improperly reads “seats” out of the claim and substitutes the seat’s “mounting points” on the frame. A proper reading of the claim language focuses on what happens when both seats are connected to the frame, not where they are so connected. In other words, “when connected to the frame” simply emphasizes that both seats must be connected to the frame to form the inline descending configuration, as opposed to the single stroller embodiment of Figure 1, where there cannot be an inline descending configuration because only one seat is connected to the frame and the other seat is removed, i.e., not connected to the frame.

    “Instead, Evenflo’s argument rests on isolating the statement—“A similar sub-frame arrangement is disclosed in [Offord ’797]”—from the remainder of the passage in which that statement appears in order to arrive at a reason to incorporate the reversibility teaching of Offord ’797. However, when that statement is read in the context of the full passage in which it appears, nowhere does that passage suggest reversibility as the reason for referencing Offord ’797. More accurately, it suggests a different reason that relates to a curved lug 108 by which sub-frame 100 rests on the stroller’s main frame 4 to carry the weight of the stroller’s two occupants— When the interface components 100 are attached to the frame assembly 4 they form a sub-frame of the frame assembly 4, and when the child-carrying units are mounted thereon, one behind the other, they are in a compact echelon formation, one of the connector sockets 106 of each component 100 being at a higher level in relation to the ground than the other connector sockets 106. The higher connector socket 106 and further connecting leg 102 are both connected to the respective opposite ends of an upper mounting piece 107. In addition, on the inner side of the lower connector sockets 106 there is a downwardly curved lug 108 which serves to rest upon a part of the basket frame 44, such that the weight of two infants is fully supported by the frame assembly 4. A similar sub-frame arrangement is disclosed in [Offord ’797]. Ex. 1051, 9:23–36 (emphasis added). That passage shows that, rather than reversibility of the sub-frame, the reference to Offord ’797 is more aptly directing the reader to the arrangement and details of a similarly curved lug structure in the stroller sub-frame of Offord ’797. Indeed, Figures 5 and 6 of Offord ’797, reproduced below, disclose just such a curved lug in the context of “corner pieces 20” having “channel 21.” Ex. 1054, 4:10–23.” slip op. at 53

    “skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Patent Owner argues that Menon teaches away from a combination with Trefethen because “Menon expressly states that Trefethen’s first-generation architecture is inadequate for the objectives that motivated the newer design.” Resp. 35–37. The evidence does not support Patent Owner’s position. First, Patent Owner’s teaching away argument is inconsistent with the strong evidence of a motivation to combine Menon and Trefethen discussed above. Second, Patent Owner’s teaching away argument is contrary to the evidence of record for the reasons given in Petitioner’s Reply. Reply 13–15 (e.g., “Menon explicitly cites Trefethen and explains that Menon builds on the teachings of Trefethen.”) (citing Pet. 22; Ex. 1003 ¶ 70; Ex. 1005, 1–3; Ex. 1163 ¶¶ 47–53). We are further persuaded by Dr. Bajaj’s reply testimony: the “MultiMATLAB teachings in Trefethen. In fact, Menon describes enhancing the system of Trefethen. For example, Menon describes a list of “goals” already achieved by MultiMATLAB and then states that the architecture has been “redesigned to achieve two further goals.” One of these two “further goals” is “extensibility,” which Menon achieves by its description of adding “MEX routines” to the system of Trefethen. Far from showing an “incompatibility” between Menon and Trefethen as the POR argues, Menon’s addition of the “MEX routines” to MultiMATLAB shows that such a modification was within the capabilities of a POSITA, because the authors of the Menon paper actually implemented the modification. Ex. 1163 ¶ 49 (citing Ex. 1005, 1–3). Dr. Bajaj’s testimony is unrebutted, credible, and supported by the record. We agree with Dr. Bajaj’s reasoning, which is based on direct quotes in Menon. We further agree with Dr. Bajaj’s conclusion that Menon does not teach away from the combination with Trefethen. Id. ¶¶ 50–52. Menon’s description of building on and enhancing the teachings of Trefethen—the earlier work of the same research group at Cornell—by adding MEX routines to achieve high-performance parallel computing and extensibility for MATLAB, demonstrates a classic motivation for a POSITA to combine the teachings of Menon and Trefethen. RS6000 and POEref are specifically referenced in Menon-Trefethen and add operational details of the parallel operating platform that teach a POSITA how to implement the MultiMATLAB system with a reasonable expectation of success. Such facts are inconsistent with Patent Owner’s teaching away and lack of motivation arguments.” slip op. at 24

    “A POSITA would have had an especially strong reason to read these references together because they address the same project, the same MATLAB-based parallel-computing problem, and the same MultiMATLAB command environment. Menon expressly identifies Trefethen’s MultiMATLAB work and then describes a redesigned architecture that preserves the same user-level objective––parallel MATLAB computations—while improving implementation details and extensibility. A POSITA therefore would not view the references as mutually exclusive alternatives. Rather, a POSITA would understand Trefethen as teaching specific MultiMATLAB commands and examples, including Eval, Send, Recv, and the architecture was implemented and improved in a later version. Ex. 1163 ¶¶ 71–72 (emphases added). We find the above reasoning persuasive and adopt it as our own. Petitioner and Dr. Bajaj demonstrate a sound technical motivation for a POSITA—someone having a bachelor’s degree in computer science, computer engineering, or electrical engineering and two years of experience working in the field of cluster computing or parallel processing—to combine Menon and Trefethen: to improve MATLAB’s operational performance and extensibility in a parallel operating environment. Menon builds on Trefethen to improve and extend the parallel processing capabilities of MultiMATLAB: “This system will enable users to access high-performance parallel routines from within the MATLAB environment, to extend the environment with new parallel routines, and to use these routines to develop parallel applications with the MATLAB language.” Ex. 1005 Abstract. Menon is intended to be read in conjunction with Trefethen, as would be expected from two references generated by the same research group at the same university addressed to the same technical subject matter about a year apart.

See Phillips, 415 F.3d at 1314 (“In some cases, the ordinary meaning of claim language as understood by a person of ordinary skill in the art may be readily apparent even to lay judges.”). We find that the plain meaning of “icon” as claimed encompasses at least “textual elements” because claim 20 recites “the icons comprise textual elements.” See id. (“Other claims of the patent in question, both asserted and unasserted, can also be valuable sources of enlightenment as to the meaning of a claim term.”). We highlight that the additional intrinsic evidence cited by the parties is consistent with the plain meaning. For example, Figures 1 and 2 of the specification show icons comprising textual elements. As another example, during prosecution of the ’058 patent, the Examiner found that the claimed icons were taught by textual hyperlinks. Ex. 1002, 586, 592. In order to overcome the Examiner’s rejection and obtain an allowance (id. at 641–50), applicant subsequently amended the claims to recite “specifically designed,” thus implicitly conceding to the Examiner’s interpretation of icon as encompassing textual hyperlinks.

However, rather than use "configured to", in order to avoid any confusion as to the narrower scope of the claims as amended, Applicant herein directly and explicitly requires "designed to."

This is consistent with our determination that “electrode stack” is a conductor that provides a path for current entering or leaving a medium such as a semiconductor device We disagree with Patent Owner that “electrode stack” as used in the challenged claims should be limited to the specific electrodes shown in the embodiments described in the Specification. See PO Resp. 4–9. Although the Specification describes embodiments using source, drain, and Schottky gate electrodes as electrical contacts, we see no reason to construe the term “electrode stack” itself to be limited to these components as Patent Owner proposes. Claims 1 and 13 expressly recite that electrode stacks comprise the claimed “electrical contact,” without expressly including or precluding any specific type of electrode. Ex. 1001, 5:54–63, 6:37–47. The Federal Circuit advises that the Specification “is not a substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach.

    “that the identified layers in Usui’s interconnect metallurgy structure form an “electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. See Pet. 11–12 (citing Ex. 1002 ¶¶ 89–91). Neither Petitioner nor Dr. Zhao, however, provide adequate explanation or evidence as to why Usui’s interconnect metallurgy structure forms an “electrode stack,” i.e., a conductor that provides a path for current entering or leaving a medium such as a semiconductor device. Dr. Zhao’s testimony merely repeats the disclosures in Usui and concludes, without further technical detail, explanation, or reference to objective evidence, that Usui’s Figure 8 discloses an electrode stack. Ex. 1002 ¶¶ 89–91. Dr. Zhao’s testimony sets forth Petitioner’s conclusory assertions as though they are facts, rather than setting forth facts and evidence in support of those assertions. Compare id. with Pet. 11–12. Absent underlying facts or evidence to support Dr. Zhao’s opinion, the cited testimony “adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In contrast, Patent Owner’s declarant Dr. Piner testifies, with evidentiary support, that interconnects (such as Usui’s interconnect metallurgy structure) and electrical contacts (such as that claimed in the ’562 patent) are not the same thing. See Ex. 2024 ¶¶ 63–70. For example, Dr. Piner explains: In other words, not all metals in a semiconductor device have the same purpose and could not be said to be interchangeable. By August 2009 it was well known to a POSA how to discern if a metal component in a transistor is an interconnect or serves as an electrical contact such as a gate contact or ohmic contact, based on the structure and functionality of the metal component. For example, interconnects are made up of metal strips and are deposited on insulators. EX-1011 (Mishra) at 216. Interconnects are low resistance conductors that can carry very high current densities. Id., 216, 217. Unlike Schottky contacts and ohmic contacts, interconnects do not provide non-linear IV response like Schottky contacts nor inject electrons and holes into semiconductors like ohmic contacts. Id., 218. As many of the references cited by Dr. Zhao illustrate, electrical contacts had their own highly complex design challenges. EX-1008 (Pearton), 41-59 (Pages 53-71 of 383) (discussing electrical contacts); EX-1017 (Kramer), 11-126 (Pages 18-130 of 151) (same). And while Dr. Zhao cites these as supporting a POSA’s knowledge of an electrical contact, none of these references describe electrical contacts as interconnects. Id. ¶ 71. Dr. Piner further testifies that Usui’s interconnect metallurgy structure is an interconnect, and not an electrical contact, because “Usui states that ‘[t]he structures fabricated by the process of the present invention are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.’” Id. ¶ 148 (citing Ex. 1004, 1:11–14) (alteration in original); see also id. ¶¶ 150– 151 (Dr. Piner testifying that Usui’s interconnect metallization structure is not an “electrode stack” under a broad definition of electrode).

After reviewing the complete trial record, we are not persuaded that Petitioner has done so.

Petitioner argues, and we agree, that the Specification strongly supports this construction (requiring a server and webpage(s)) by describing a “website” as synonymous with a server computer system: “The WWW [(World Wide Web)] service allows a server computer system (i.e., Web server or Web site) to send graphical Web pages or screens of information such as the advertising materials to a remote client computer system 10.” Ex. 1001, 3:66–4:2 (emphases added); see id. at Fig. 1 (depicting a service engine and webpages as a web server, i.e., website), 3:15–18 (describing Figure 1 as showing “a server of the website” (emphasis added)); Pet.

Petitioner also submits a supporting (and persuasive) contemporaneous technical dictionary definition of “website,” which highlights the distinction between a lay person’s understanding of the term versus that of the relevant artisan. Pet. Reply 5–6. This definition explains that the “common but technically inaccurate” usage of “website” is to mean “Web page,” but the technically correct usage of “website” is to mean “one or more computers that are associated with a fully qualified domain name and make content available on the Web.” Id. (citing Ex. 1028, 402). Petitioner’s expert, Dr. Crovella, likewise testifies that “[a] website cannot exist without the server or computer that provides its webpages.” Ex. 1026 ¶ 15; see Ex. 1027, 36:8–20 (Patent Owner’s expert, Dr. Myler, agreeing that “it has to be some machine somewhere that’s providing the webpages for the website.”). The limitations of claim 1 also support Petitioner’s position that “website” includes a server and webpage(s). Reply 5. For example, claim 1 recites advertising material for “populat[ing] on one or more websites,” and selected “advertising buy options comprise at least one website of the respective websites.” Ex. 1001, 10:29–51 (emphases added). We find these limitations make the most technical sense where “website” implicates an Internet domain or domain name, such as brodti.com, which itself is a computer system (server) and associated webpage(s) reached via that domain name. This interpretation aligns with testimony of Patent Owner’s expert, Dr. Myler, in which he states that a “website” describes “a group of webpages at a particular domain (e.g., www.espn.com, www.espn.com/nba, www.espn.com/nfl, www.espn.com/nhl).” Ex. 2009 ¶ 68 (emphasis in italics added). In other words, brodti.com and espn.com are two different websites, with each website having one or more webpages (e.g., www.espn.com/nba, www.espn.com/nfl), and such websites include a server giving life to such webpage(s). slip op. at 15
