      “Petitioner contends that a person of ordinary skill in the art would have been someone with an advanced degree involving the disciplines of electrical engineering, applied physics, chemistry, or materials science, and at least two years of experience designing, developing, or researching in the field. Alternatively, that person would have had a bachelor’s degree in electrical engineering, applied physics, or materials science, and at least three years of experience designing, developing, or researching in the field. Pet. 4 (citing Ex. 1003 ¶ 49). Patent Owner does not address the level of ordinary skill in the art. See generally PO Resp; Sur-reply. In light of the complete trial record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’104 patent and the prior art of record, we determine that the definition offered by Petitioner comports with the qualifications a person would have needed to understand the ’104 patent and the prior art.” slip op. at 9

      “C. Claim Construction We construe claim terms according to the standard set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–17 (Fed. Cir. 2005) (en banc); 37 C.F.R. § 42.100(b). Under Phillips, we give claim terms “their ordinary and customary meaning.” Phillips, 415 F.3d at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Id. at 1313. “Importantly, the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Id. Petitioner contends that “[n]o claim construction is believed to be necessary to resolve this Petition.” Pet. 23. And, Patent Owner does not address claim construction. See generally PO Resp. As neither party proposes an express construction for our consideration and because we determine that an express claim construction is not necessary for us to render a decision in this matter, we do not construe any claim terms. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

      “edge and offers little explanation of why the skilled artisan would apply Jin’s gap- T isolation region to both of Feldmann’s polysilicon and tunnel oxide layers. As noted above, Petitioner states that the skilled artisan would have included Jin’s gap-T isolation region in order to prevent shorting. Pet. 25. Petitioner’s reasoning is questionable—supported only by the conclusory testimony of Dr. Banerjee. Dr. Banerjee’s testimony offers no more evidentiary support than provided in the Petition. Compare Ex. 1003 ¶ 113, with Pet. 25. Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements.” Magnum Oil, 829 F.3d at 1380. We acknowledge Dr. Banerjee’s testimony that the combination of Jin’s gap-T isolation region would prevent shorting and that extending the tunnel oxide layer the edge “could trap impurities and create negative fixed oxide charges, which could then create a p-type inversion in the n-type base substrate, leading to a leakage path to the p-type emitter on the front of the solar cell” (Ex. 1003 ¶ 113 (emphasis added)) but are not convinced by his equivocal testimony. Notably too, neither Jin nor Feldmann discuss issues relating to trapped impurities and Petitioner, as well as Dr. Banerjee, fail to direct our attention to any record evidence to support their contentions. Rather, we are persuaded by Dr. Peckerar’s testimony that as a general rule in semiconductor process technology, a bare silicon surface should not be left unpassivated after processing. Elemental silicon is highly chemically reactive. As such, the bare surface is a “magnet” for defects and contamination. Leaving the tunnel oxide in place across the entire substrate backside would reduce this problem. Ex. 2001 ¶ 142. Dr. Peckerar further explains that a person of ordinary skill in the art would have known how to avoid shorting and leakage. In particular, he testifies that the manner by which charge is transported through a tunnel oxide can be controlled by adjusting manufacturing parameters such as time, temperature, thickness, and ambient impurities. A POSITA would plainly have adjusted these parameters to ensure that the tunnel oxide operates as intended (i.e., minimizes recombinant losses while transporting charge carriers to the backside of the solar cell) while avoiding undesirable leakage current. Because unwanted leakage charge can be avoided via other means during manufacture, there would have been no reason to reduce the physical extent of the tunnel oxide. Ex. 2001 ¶ 152 (referring to Ex. 2001 ¶¶ 149–151). Moreover, Dr. Peckerar testifies that “Dr. Banerjee also appears to be arguing that incorporation of impurities into the oxide will produce a MOSFET-like structure, with the contaminated oxide acting as a MOS gate leading to enhanced leakage,” but, for that to occur, “the source and drain areas would need to be of the same type.” Ex. 2001 ¶ 159. Here however, “the tunnel oxide layer is located between an n-type polysilicon layer and p-type frontside emitter layer” so “[n]o MOSFET-like structure can form because the source and drain are of different types.” Ex. 2001” slip op. at 18

      “base a conclusion of obviousness upon facts gleaned only through hindsight. “The invention must be viewed not after the blueprint has been drawn by the inventor, but as it would have been perceived in the state of the art that existed at the time the invention was made.” Sensonics, Inc. v. Aerosonic Corp., 81 F.3d 1566, 1570 (Fed. Cir. 1996) (citing Interconnect Planning Corp. v. Feil, 774 F.2d 1132, 1138 (Fed. Cir. 1985)). Therefore, “to establish a prima facie case of obviousness based on a combination of elements disclosed in the prior art, the [Petitioner] must articulate the basis on which it concludes that it would have been obvious to make the claimed invention.” Id. Impermissible hindsight is inferred when the specific understanding or principle within the knowledge of one of ordinary skill in the art that would motivate one (with no knowledge of the claimed invention) to make the proposed combination has not been explained.

      “arguments relating to whether the prior findings are “necessary to the determination” or whether estoppel applies to arguments relating to Richardson being inoperative. See Pet. Reply 27. Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

      “B. Level of Ordinary Skill in the Art Petitioner proposes that the level of ordinary skill in the art is an artisan with a working knowledge of POS activation systems and lottery systems that was gained through a mixture of training and work experience in the relevant field such as (i) having a Bachelor’s degree in computer science, computer communications, electrical engineering, or equivalent degree, coupled with at least three years of work experience; (ii) having a Master’s degree in computer science, computer communications, or electrical engineering, but having less work experience; or (iii) having no formal degree, but having experience in the relevant field of at least six years of work experience.

      “On balance, we find that even with the alleged disadvantages identified by Patent Owner, one of ordinary skill in the art would have been motivated to modify Szrek with Llach’s third-party transaction processor because the advantage of having a “centralized intermediary” allows Szrek’s system to support different game providers, such as different lottery companies, which would reduce some implementation costs and allow the system to be more easily and cheaply extended. Pet. 47 (citing Ex. 1003 ¶ 181); see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”) (citing Winner Int’l Royalty Corp. v.

We acknowledge that the combination comes with some disadvantages, including “add[ed] delay, reduce[d] efficiency, and . . . implementation complexities by converting a simple, direct communication exchange into an exchange that traverses multiple systems.” PO Resp. 52 (citing Ex. 2052 ¶ 163). But, “[t]he fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.” Winner, 202 F.3d at 1349 n.8. Here, Szrek expressly teaches indirect communication as a possible implementation of its system and Petitioner’s combination—employing Llach’s third-party transaction processor as part of the indirect communication channel—offers the attractive benefit of allowing Szrek’s system to support different game providers, which would reduce some implementation costs even if it might increase other costs, e.g., by having to program certain components (e.g., the cash registers) differently. Specifically, we find that the ability to expand Szrek’s system to support different game providers provides advantages that outweigh the disadvantages discussed above in the circumstance where one desires a more robust and comprehensive system.

      “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.

      “Following the block quote from Yacenda, the applicant then stated, “[b]ased on the foregoing, Yacenda’s system is directly opposite of the instant claims, as the instant claims require a ‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.’” Ex. 1002, 76. This statement is clear and unmistakable. It (1) specifically states that “the instant claims require” and (2) then states what the claims require—a “‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.” We fail to see how the applicant could have been more clear in stating a requirement of the Challenged Claims.

      “We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

      “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

Google, 34 F.4th at 1088. Cheyer’s and Martin’s testimony that Dr. Moran’s role was administrative and non-technical with respect to the core infrastructure of OAA is belied by a separate article describing OAA that includes the facilitator and lists Dr. Moran as the lead author. Ex. 1174, 1–2, 4. Indeed, the OAA article lists Dr. Moran and Mr. Cheyer as authors but excludes Mr. Martin. Id. Although Mr. Cheyer disagrees with the article’s description of the origins of OAA and the facilitator (Ex. 2037, 78:23–79:12 (Mr. Cheyer asserting that he “would not agree in the characterization of Open Agent Architecture grew out of [earlier] works” as described in the article)), Mr. Cheyer admits patent]” (id. at 1088), “which is a continuation-in-part of the application that resulted in the ’115 patent” (id. at 1086). in his deposition that Dr. Moran was extremely technical, and probably made technical contributions to OAA (id. at 34:1–20, 64:16–20, 102:2–4).

When viewed in light of Dr. Moran’s status as a joint inventor on the closely related ’931 patent (Ex. 2002, code (75)) and as a lead author of the substantive paper that discusses OAA’s early development, we find Mr. Martin’s and Mr. Cheyer’s admissions—that Dr. Moran made technical contributions to OAA—undermine their testimony that Dr. Moran’s inclusion as an author on the Martin reference was a matter of administrative respect and not a result of a technical contribution. See PO Remand 11; PO Resp. 50–51. Indeed, we find Cheyer and Martin’s general description of Dr. Moran—as an administrator without technical contributions to the Martin reference—is not supported by the full record, which instead supports Dr. Moran’s contributions to technical work that involves the Martin reference, such as contemporary papers and the ’931 patent. See, e.g., Ex. 1174, 2002.

      “construe claims “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b); see Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). Furthermore, we expressly construe the claims only to the extent necessary to resolve the parties’ dispute. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Ltd., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). The parties agree that the terms of the challenged claims should be given their “plain and ordinary meaning” and that no express claim construction is necessary to address Petitioner’s challenges. Pet. 12; PO Resp. 6. We agree that no claim terms require express construction for purposes of resolving the dispute between the parties.” slip op. at 10

      “Upon review, we are unpersuaded that Petitioner has improperly mixed and matched disclosures from Johnson to arrive at an anticipatory reference. Patent Owner is correct that Petitioner primarily relies on Example 1 as evidence for the method by which its scaffold is made. But the disclosure found in paragraph 98 is not a “distinct” teaching of the type described in Net MoneyIN; rather, it is a general description of the structures that may be created by Johnson’s method: “A scaffold may comprise any number of layers, including about 1 layer, about 2 layers, about 3 layers, about 4 layers, about 5 layers, and so on.” Ex. 1009 ¶ 98. Patent Owner has not directed us to anything in the disclosure of Johnson that indicates that this is a “distinct” teaching or embodiment, instead of a general description of the types of scaffolds that Johnson encompasses. We see no reason why the general disclosures regarding Johnson’s scaffolds should be limited to specific embodiments, or precluded from applying to the method of Example 1.” slip op. at 14

      “We are unconvinced by Petitioner’s arguments and evidence. While we recognize that the range of claim 3 is very broad, and it is possible that scaffolds having fiber diameters as set forth in Johnson could have a mean pore size falling within the range, inherency “may not be established by probabilities or possibilities.” Par Pharm., Inc. v. Twi Pharms., Inc., 773 F.3d 1186, 1196 (Fed. Cir. 2014). Nor does Petitioner sufficiently explain why a person of ordinary skill in the art would have understood the process of Example 1 to necessarily result in the claimed mean pore size. We are also persuaded by Patent Owner’s argument that Boland 2005’s disclosure of a fiber diameter similar to Johnson’s that nevertheless falls outside the claimed mean pore size range. We note that Petitioner never addresses Boland 2005 in its Reply. 4. Conclusion as to Anticipation For these reasons, we find that Petitioner has met its burden of showing that claims 1, 2, 4, 5, and 13 are anticipated by Johnson, but has failed to meet its burden as to claim 3.” slip op. at 18
