      “c. Analysis “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros. v. Union Oil Co. of California, 814 F.2d 628, 631 (Fed. Cir. 1987). We are persuaded by Patent Owner’s argument that Avellan does not anticipate claim 1 because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 26–29. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. Sur-reply 21. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

      “All other challenged claims require the “generating” and “assembling” operations because they depend from claims 1, 12, or 17. Petitioner does not allege that the additional references—Durante, Ma, Suzuki, Wanamaker, Heikens, Matthews, or Wilsher—teach or suggest the “temporal sequence of screen captures” recited in claim 1. Rather, Petitioner’s reasoning in the challenges to the dependent claims pertaining to the screen captures mirror the rationale presented in the independent claim. See, e.g., Pet. 25 (arguing that Avellan’s screen captures correspond to the video content in the challenge to claim 2), 26–27 (arguing that Avellan obtains screen captures from a playback of a video on the webpage in the challenge to claim 4). Petitioner’s argument that Avellan teaches or suggests these operations in the grounds based on obviousness under 35 U.S.C. § 103 depend on the reasoning and insufficiently supported characterizations of Avellan in the challenges based on 35 U.S.C. § 102, as discussed above.

Reply 7 (quoting Ex. 1012, 5:59–67). We disagree. Instead, we agree with Patent Owner that Suzuki’s irregular-surface smoothing describes covering defects, not suppressing the underlying cathode’s topography. PO Sur-reply 5. The smooth-surface passage that Petitioner highlights comes immediately after two sentences describing inevitable “defects,” “pinholes,” and “foreign matter” on the cathode surface and before a sentence describing “ensuring the formation of the layer 22, which is substantially defect-free.” Ex. 1012, 5:52–67. Suzuki’s organic barrier 20 “makes a smooth surface” by covering defects because the defects are the only source of the “irregularity” that Suzuki refers to here. Id. We note Mr. Humphrey’s testimony, which we credit in this regard, that the “defects are created incidentally on the surface of the underlying layer and are generally not considered to be part of the underlying layer’s topography, which is a macroscopic property by design” and that the organic layer is not a planarization layer because it would reproduce the topography of the underlying layer.

      “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012).

Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

      “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

      “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A.

      “remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A.

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for patent owner

      “We determine that the evidence of record overcomes the presumption that § 112, para. 6 does not apply because “thrust-bearing element” does not recite sufficiently definite structure in this case. See, e.g., Pet. 22 (the term is not used here according to its common meaning). First, the word “element” is a “[g]eneric term[]” or “verbal construct[]” often “used in a claim in a manner that is tantamount to using the word ‘means’” because it does not “connote sufficiently definite structure.” Williamson, 792 F.3d at 1350. We find nothing in the ’121 patent or elsewhere in the record suggesting that “element” in the term “thrust-bearing element” should be considered other than a generic placeholder term. Second, although the term “thrust bearing” may connote certain structure, “thrust-bearing element” does not. A “thrust bearing” is “a well-known term of art in engineering and is ‘a bearing which sustains axial loads and prevents axial movement of a loaded shaft.’” Ex. 1003 ¶ 46 (citing Ex. 1017, 2147). “The balls of traditional thrust bearings are positioned inline with the axial force, as thrust bearings are designed specifically to transmit axial load.” Id. Here, however, “thrust-bearing” is hyphenated, and is therefore a phrasal adjective modifying “element” rather than the noun phrase “thrust bearing.”8 Further, there are “substantial differences”” slip op. at 15

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Term construed board ownDecided for patent owner

      “We largely agree with Petitioner. “[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.” B. Braun Med. Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.Cir.1997). The Specification of the ’121 patent “clearly links or associates” two components with the function of bearing axial thrust from the sowing disc: shaft 27 with flanging 30, and thrust-bearing plate 31. Ex. 1001, 3:25–35. Thrust-bearing plate 31 is expressly described as “bear[ing] on that surface of the disc which faces seal 24 . . . in order to withstand at least some of the axial load produced by the disc 16 on the seal 24. Ex. 1001, 3:28–31. Rotatably-mounted shaft 27 with flanging 30 is “fixed” to thrust-bearing plate 31 and therefore bears the axial load from the disc via the thrust-bearing plate. Id. at 3:25–28.10 10 Drive element 32 is described as part of thrust-bearing element 26 and permits thrust-bearing element 26 to be driven in rotation with sowing disc 16. Ex. 1001, 3:36–40. It is not described as bearing any axial load, however. Further, it is not necessary for the thrust-bearing element to rotate with the sowing disc for that element to bear axial load from the sowing disc. See id. at 3:58–59 (“Provision is also made for the thrust-bearing element 26 to be made idle and not driven in rotation by the [drive] shaft 20.”). Ultimately, however, whether drive element 32 is properly considered as part of the corresponding structure is not relevant to the outcome of this case. We disagree with Patent Owner that bearings 28 and seat 29 should be considered corresponding structure. The Specification does not associate these structures with any axial load-bearing function. Instead, bearings 28 and seat 29 are described as the means by which, and the location in which, shaft 27 is rotatably mounted. Ex. 1001, 3:25–27. Regardless, whether or not bearings 28 and seat 29 are considered corresponding structure does not affect the outcome of this case. In summary, we construe “thrust-bearing element” as a means-plus- function claim term under 35 U.S.C. § 112, para. 6. Its recited function is to bear thrust, or more specifically to “withstand at least some of the axial load produced by the disc on the seal.” The structure described in the Specification as corresponding to this function is shaft 27 with flanging 30, and thrust-bearing plate 31. We construe the limitation as directed to this structure, and equivalent structures.” slip op. at 21

Instead, we must simply ascertain what the patentee meant by “supported rotatably in the movable portion.” To answer this question, we look to the Specification, which “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315. “The construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be, in the end, the correct construction.” Id. at 1316. Here, it is undisputed that in the sole embodiment described by the ’121 patent, the thrust-bearing element is supported by and entirely within the movable portion of the housing. Ex. 1001, Figs. 1, 2; Pet Post-Hearing Resp. 1; PO Post-Hearing Resp. 2. Construing “in the movable portion” to require the thrust-bearing element to be entirely within the movable portion both “stays true to the claim language and most naturally aligns” with the sole disclosed embodiment. Such a construction does not import the word “entirely” from the sole embodiment into the claims because the construction “arises from the claim language itself.” See SharkNinja Operating LLC v. iRobot Corp., 2024 WL 1132219, *2–*3 (Fed. Cir. 2024) (construing “primary brush assembly disposed within the round housing perimeter” to require that the primary brush assembly be “entirely within” the round housing perimeter is not an improper incorporation of “entirely” from embodiments into the claims because the construction “arises from the claim language itself”). Accordingly, having reviewed the complete record and the parties’ pre- and post-hearing briefing, we determine that “supported rotatably in the movable portion” means supported rotatably entirely in the space defined by the movable portion.” slip op. at 25

      “b. When “Thrust-Bearing Element” is Construed as a Means-Plus-Function Claim Limitation, there is Insufficient Evidence in the Record to Support a Finding that VenHuizen Discloses a Thrust- Bearing Element that is Supported Rotatably in the Movable Portion As noted above, Petitioner contends that VenHuizen’s shaft 55, retaining hub 56, and handle 58 together constitute the claimed thrust-bearing element “under a proper means-plus-function definition.” Pet. Reply 18–19.12 We do not discern sufficient evidence of record or persuasive technical reasoning from Petitioner to support a finding that these elements together are “supported rotatably in the movable portion” of the housing, as claim 1 requires. Ex. 1001, 4:38–39. We construed this limitation to require the thrust-bearing element to be supported rotatably entirely in the space defined by the movable portion (the space defined by VenHuizen’s second housing member 90). Petitioner does not contend, much less show, that these components are supported rotatably entirely in the movable second housing member 90. On the contrary, of the three components constituting VenHuizen’s thrust-bearing element, all of retaining hub 56 and most of shaft 55 are located in the fixed portion of the housing (first housing member 50), not the movable portion 90. See Ex. 1001, Fig. 6. Only handle 58 is ever located in the movable portion (when the fixed and movable portions are joined together). See id.

      “We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

      “combined Lee and Watanabe to achieve improved integration density. Pet. 71. Petitioner concedes, however, that the benefits of Lee’s design related to 3-D integration and improved integration density would be obtained if Lee’s memory structures are formed using either Lee’s monolithic construction method or Watanabe’s alternative stacking method. Pet. Reply 13–14 (citing Ex. 1041 ¶ 34). Thus, we are not persuaded that improved integration density provides a sufficient rationale for Petitioner’s combination of Lee’s memory device and Watanabe’s stacking method. Petitioner argues that Watanabe’s stacking method “improves the accuracy of the wiring” because the wiring is made “for each planar member.” Pet. 72 (citing Ex. 1005, 6:1–3). Watanabe also states that its disclosed methods provide “a low interconnection wire resistance.” Ex. 1005, 6:20–23. Petitioner does not, however, explain sufficiently how Watanabe’s stacking method would improve Lee’s device. For example, Petitioner does not address whether the alleged wiring benefit already existed in Lee’s monolithic array or explain how this benefit would also apply to Lee’s particular memory array, which differs in construction and elements from Watanabe’s device. This diminishes Petitioner’s benefits-based motivation to combine arguments. In general, a petitioner need not demonstrate that a particular alternate method would improve a prior art device in order to show a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023); see Pet. Reply 20 (citing Intel). But here, Petitioner affirmatively invokes improvement of Lee’s device as a reason for the combination, and we must evaluate Petitioner’s contention. Moreover, any relative lack of improvement or benefits must be weighed against any problems the alternative method would introduce. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795–96 (Fed. Cir. 2021) (noting that simultaneous advantages and disadvantages to a proposed combination must be analyzed to determine whether the disadvantages “outweighed any reason to combine”). Here, as discussed above in more detail with respect to the ground based on Watanabe, the evidence shows that one of ordinary skill in the art would have expected Watanabe’s bonding temperature of 900– 1000° C to damage the electronic devices in an underlying substrate. Ex. 2029 ¶¶ 75–76; Ex. 2028, 123:13–124:7; Ex. 2027, 715. The expected damage to Lee’s device, when balanced against the limited evidence of a benefit to the combination,7 outweighs the reason to combine Lee and Watanabe set forth in the Petition. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious over Lee and Watanabe. 2.

However, the language of claim 1 is very clear on the functionality of the “open tip,” expressly reciting that “the open tip cuts bone tissue away from the sacrum or the ilium.” Id. at 13:19– 20. Thus, the claim language itself provides the required functionality of the “open tip,” and we do not agree with Petitioner that additional functionality relating to where bone tissue might go once cut, as discussed in the Specification, should be read into the claims as a limitation. Patent Owner’s newly proposed interpretation is similar to Petitioner’s in that it requests addition of functionality discussed as an example in the Specification, but not recited in the claim’s expressly recited functional language relating to the “open tip.” We disagree with Patent Owner that the concept of dislodged tissue entering a void defined by the open tip is necessary to understanding the claim element. And, once more, Patent Owner reads too much structure from the written description into the claim language as a limitation because it is not apparent that the recited “open tip” language requires that we further clarify that any interior void defined by the open tip is on the interior of the abrading head, and behind the exterior abrading surfaces, or between interior surfaces of a first pair of opposing sides, as proposed by Patent Owner. “[W]hile it is true that claims are to be interpreted in light of the specification . . . , it does not follow that limitations from the specification may be read into the claims. . . .

See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc). Here, the word “means” is recited, followed by functional language, and the claim recites no structure associated with the means or function. Moreover, the parties agree that this is a means plus function limitation. See Pet. 19–20; Resp. 9.

Based on the competing proposals, arguments, and evidence before us, we adopt and apply the following level of skill in assessing Petitioner’s challenges to the patentability of the claims of the ’329 patent: a person that would have had a bachelor’s degree in computer science, computer engineering, or electrical (or similar) engineering with about three years of experience being in the field of internet advertising.” slip op. at 10

      “Petitioner’s resurrected argument is based on a fundamental misunderstanding of § 311(b). Section 311(b) provides: “A petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed cancel the claims of the ’329 patent on the basis of Badros, Harkins, and Krassner. Pet. 11. Petitioner did not base its request, in whole or in part, on the Krassner publication. Id. Krassner clearly is a patent. It issued on August 13, 2019, far too late to be § 102(b) prior art. Even if we assume Krassner is also a “printed publication” withing the meaning of § 311(b), the same date would apply: August 13, 2019. Petitioner has not presented any evidence that the document that is Krassner was published prior to when it issued on August 13, 2019. That another document (the Krassner publication), which published much earlier, may contain the same or similar disclosure is not relevant to when Krassner was patented or published. In sum, Krassner is not prior art under 35 U.S.C. § 102(b). b) Whether Krassner is Prior Art Under 35 U.S.C. § 102(e) Although Krassner is not prior under 35 U.S.C.§ 102(b), we” slip op. at 13

      “Petitioner responds that, contrary to Patent Owner’s argument, “Harkins teaches that its invention can be used in web pages.” Pet. Reply 18 (citing Ex. 1004 ¶30). Although Petitioner’s citation is off by one paragraph, Petitioner’s response about what Harkins teaches is correct. See Ex. 1004 ¶29 (“The present invention may be implemented for provision of virtually any type of advertising (e.g., print, radio, television, Internet, billboard, etc.) via any type of advertising medium (e.g., newspaper, magazine, radio broadcast, Web pages, billboards, etc.) without departing from the scope of the present invention.”). We find that Harkins is from the same field based on its express statement that it is applicable to “virtually any type of advertising” and “any type of advertising medium,” including “Web pages.” Ex. 1004 ¶29. Further, even if this were insufficient to place Harkins in the same field as the ’329 patent, we find that Harkins is reasonably pertinent to the particular problems with which the ’329 patent inventors were involved. In sum, we find that Harkins is analogous art to the ’329 patent.” slip op. at 19

      “Paper 60 (“PO Mot. To Exclude”), 9–10.6 Patent Owner is correct in this regard and, thus, we grant Patent Owner’s Motion to Exclude with respect to the testimony in the second Smedley Declaration and the Madansky Declaration opining that Badros teaches the determination limitation. Paper 60, 9–12. Petitioner, in its Opposition to the Motion to Exclude, argues that Patent Owner’s arguments about the “viewability test” were “surprising.” Paper 62, 8. We are not persuaded by Petitioner’s argument. The “viewability test” is a claim limitation. Petitioner should have anticipated that Patent Owner would argue that limitation. See In re Gardner, 449 F. App’x 914, 916 (Fed. Cir. 2011) (“This court has held that when evaluating claims for obviousness under 35 U.S.C. § 103, all the limitations of the claims must be considered and given weight.” (citing Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530 (Fed. Cir. 1983)); Univ. of Strathclyde v. 6 Patent Owner’s Motion to Exclude seeks to exclude, in part or in whole, Exhibits 1020–1022, 1025–1030, and 1034–1040, which were submitted with Petitioner’s Reply, of which Exhibits 1026 and 1027 are the declaration by Dr. Madansky and the second declaration by Dr. Smedley, respectively. Mot. To Exclude. The Motion to Exclude also seeks to exclude “Exhibits” 1017 and 1018, which are not filed or of record in this case but which are referenced in the Reply. Id. For example, Exhibit 1017 is the Krassner publication, which Petitioner unsuccessfully moved to add to the record as supplemental information. See Paper 21, 3 n.1 (expunging the Krassner publication and stating that it “need not -- and indeed may not -- be re-filed under a new exhibit number”). Apart from the portions of Dr. Smedley’s second declaration and Dr. Madansky’s declaration opining that Badros teaches the “determination” limitation, we dismiss the Motion to Exclude as moot. obviousness determination generally requires a finding that “all claimed limitations are disclosed in the prior art’.” (citing PAR Pharm., Inc. v. TWI Pharms., Inc., 773 F.3d 1186, 1194 (Fed. Cir. 2014)). Petitioner argues that “[v]iewability tests were well known for well over a decade prior to the ’329 patent’s priority date.” Reply 9. If that were the case, then Petitioner should have made its argument in the Petition. Section 312(a) of Title 35 is titled “Requirements of Petition,” and it specifies that a petition must identify, among other things, “the evidence that supports the grounds for the challenge to each claim, including . . . (B) affidavits or declarations of supporting evidence and opinions, if the petitioner relies on expert opinions.” 35 U.S.C. § 312(a)(3); see also 37 C.F.R. § 42.104(b)(4)–(5) (“The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon; and . . . the supporting evidence relied upon to support the challenge.”). Thus, “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Board’s Consolidated Trial Practice Guide, 73 (Nov. 21, 2019).7 Dr. Smedley’s testimony in his second declaration, that “Badros discloses Patent Owner’s ‘viewability test’” (Ex. 1027 ¶11), is clearly evidence to make out a prima facie case of unpatentability. The same is true of Dr. Madansky’s testimony that she agrees with Dr. Smedley in this regard. Ex. 1026 ¶4.” slip op. at 25
