      “Institution of an inter partes review is authorized by statute only when “the information presented in the petition . . . and any response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). We have authority, acting on the designation of the Director, to determine whether to institute an inter partes review. 37 C.F.R. § 42.4(a). For the reasons set forth below, upon considering the Petition, Preliminary Response, and evidence of record, we conclude that the information presented in the Petition fails to establish a reasonable likelihood that Petitioner would prevail in showing the unpatentability of any of the challenged claims. Accordingly, we decline to institute inter partes review.” slip op. at 2

      “Petitioner contends that a person having ordinary skill in the art at the time of the invention would have had “at least a Master’s degree in electrical engineering and two or more years of work experience relating to power electronics and the manufacture of power converters or printed circuit board design for power converters,” but acknowledges that “[a]dditional education might compensate for less work experience, and vice-versa.” Pet. 14 (citing Ex. 1013, 79). Patent Owner does not contest Petitioner’s proposed definition or proffer a definition of its own. See generally Prelim. Resp. Patent Owner’s witness, Dr. Rivas-Davila, asserts that he applies Petitioner’s definition. Ex. 2001 ¶ 77. We find Petitioner’s definition of the level of ordinary skill in the art to be consistent with the problems and solutions disclosed in the ’761 patent and prior art of record, and adopt it as our own for purposes of this Decision. See Okajima, 261 F.3d at 1355.” slip op. at 9

      “Ex. 1001, 28:13–33. The court’s analysis of “plurality” in Apple applies here. Consistent with Apple and other precedent of our reviewing court, we interpret “plurality” to mean two or more. See Dayco Prods., Inc. v. Total Containment, Inc., 258 F.3d 1317, 1327–28 (Fed. Cir. 2001) (“In accordance with standard dictionary definitions, we have held that ‘plurality,’ when used in a claim, refers to two or more items, absent some indication to the contrary.”); York Prods., Inc. v. Cent. Tractor Farm & Family Ctr., 99 F.3d 1568, 1575 (Fed. Cir. 1996) (“The term [‘plurality’] means, simply, ‘the state of being plural.’”). And as explained above, neither the ’761 patent nor its prosecution history indicates that “a plurality of power semiconductor devices” as used in claim 1 refers to a subset, rather than all, of the power semiconductor devices in the power converter. See Ex. 1001, 23:24–42, 24:7–25:32; generally, Ex. 1004. As discussed in more detail below, Petitioner maps “plurality of power semiconductor devices” to a subset of the power semiconductor devices in the device disclosed in Ericsson-BMR, implicitly interpreting this language to mean less than all of the power converter power semiconductor devices of the power converter. Petitioner’s interpretation that “plurality of power semiconductor devices” is satisfied by a subset of the power semiconductor devices does not accord with the Federal Circuit’s interpretation of “plurality” as set forth in Apple and is at odds with the requirement that “the power semiconductor devices are distributed between the first and second sets” as recited in claim 1. See Apple, 695 F.3d at 1379. Accordingly, we interpret “a power converter including . . . a plurality of power semiconductor devices” as recited in claim 1 to refer to all of the power semiconductor devices in the power converter, not merely a subset of the power semiconductor devices.” slip op. at 14

      “Petitioner fails to identify with requisite particularity how BMR-2008 renders the challenged claims obvious. See 35 U.S.C. § 312 (a)(3). Petitioner has made no showing of the grounds on which the challenged claims are based; Petitioner makes no mapping whatsoever of the BMR-2008 disclosure to the challenged claims, instead suggesting that we compare the disclosures of BMR-2008 and Ericsson-BMR. This is insufficient to meet Petitioner’s obligation to identify with particularity how the asserted references satisfy the requirements of the challenged claims. For at least the foregoing reasons, Petitioner does not demonstrate a reasonable likelihood of prevailing in showing that claim 1, or its dependent claims 2–7, would have been obvious in view of Ericsson-BMR alone or in combination with Spiazzi, Wanes, or Takeshima.” slip op. at 46

      “We have considered Petitioner’s Request for Rehearing and, for the reasons set forth below, we grant Petitioner’s Request for Rehearing, but we are not persuaded to change our ultimate conclusion to deny institution of inter partes review. II. STANDARD OF REVIEW A party requesting rehearing bears the burden of showing the decision should be modified. 37 C.F.R. § 42.71(d). A request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed.” Id. When rehearing a decision on petition, we review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion occurs when a “decision was based on an erroneous conclusion of law or clearly erroneous factual findings, or . . . a clear error of judgment.” PPG Indus.” slip op. at 3

      “III. DISCUSSION OF THE REQUEST FOR REHEARING On May 4, 2020, we issued our Decision denying institution of inter partes review based upon: (1) the advanced stage of the California District Court proceeding; (2) the investment of time and resources by the District Court and the parties in the California District Court proceeding; (3) overlap in the invalidity theories that Petitioner is pursuing here and in the California District Court proceeding; and (4) overlap in the claims challenged in the California District Court proceeding. Inst. Dec. 6–12. In the Decision, we did not reach any of the ten substantive grounds for patentability. See generally Inst. Dec. Rather, the denial of institution was solely based on our findings under 35 U.S.C. § 314(a). Id.” slip op. at 4

      “The petition must identify with particularity each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim. 35 U.S.C. § 312(a)(3); see also 37 C.F.R. § 42.22(a) (content of petitions); 37 C.F.R. 42.104 (content of petition). Petitioner’s conclusory statements, without more, are irreparably lacking in detail. Petitioner does not provide any analysis to support the assertion of obviousness over Oki. In fact, Petitioner instead asserts that Oki discloses all of the limitations in each of claims 1, 2, 4–7, 9, 15, 16, and 18, so it is unclear what modification, if any, is required to Oki, or even the basis of Petitioner’s obviousness grounds. E.g., Pet. 28– 33. Petitioner does not clearly point out the differences between the claimed invention and Oki. Nor does Petitioner explain why a person of ordinary skill in the art would have found the claimed subject matter obvious in spite of those differences. Petitioner has not provided sufficient reasoning or facts on which to base a conclusion that a person of ordinary skill in the art would have found it obvious, in light of Oki’s disclosure, to modify Oki to meet the claim limitations. Accordingly, Petitioner fails to demonstrate a reasonable likelihood that it would prevail on this ground of unpatentability.” slip op. at 28

      “decision is abuse of discretion. 37 C.F.R. § 42.71(c). The requirements are set forth in 37 C.F.R. § 42.71(d), which provides in relevant part: A party dissatisfied with a decision may file a request for rehearing, without prior authorization from the Board. The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. We grant Petitioner’s request insofar as we have reconsidered our interpretation of the challenged claim terms, but we decline to modify our previous decision.” slip op. at 2

      “reasonable interpretation of “selecting the file based on whether content of the file matches a file type indicated by a name of the file” in view of the Specification of the ’298 patent includes “a sequence of linked examinations of the indicated file type and file content that demonstrates a mismatch.” Also, as we determined previously, the portions of Chen relied on in the Petition describe examining the file content and file extension, but not comparing the file content to the file extension. Dec. 11. Thus, after considering our previous analysis in view of Petitioner’s proposed interpretation, we determine that Petitioner has not demonstrated Chen discloses “selecting the file based on whether content of the file matches a file type indicated by a name of the file,” as recited by independent claims 1, 10, and 16. Accordingly, we are not persuaded to modify our decision denying institution based on Petitioner’s challenge of claims 1, 2, 6, 7, 9–11, and 16 as anticipated by Chen and Petitioner’s challenge of claims 3–5, 8, and 12– 15 as obvious over Chen and either Ji, Korn, Kim, or admitted prior art, which do not address the deficiency regarding the “selecting” step.” slip op. at 7

      “Id. at 3. In the cited portion, the ’298 patent states that “the retrieved file is examined to determine whether the file structure is as expected for a file of the indicated type.” Ex. 1004, 7:5–7. The ’298 patent also states that “[a]lternatively, files can be checked to ensure that they actually contain the type of data described by the file type marker.” Id. 7:9–10. The ’298 patent, thus, supports Petitioner’s interpretation that “a selection based on whether a file content matches the file type indicated by the file name may be accomplished by a direct comparison between two items,” because it describes a direct comparison. The same portions of the ’298 patent, however, do not support Petitioner’s interpretation that the “selecting” step also includes “a sequence of linked examinations of the indicated file type and file content that demonstrates a mismatch” because it does not describe an examination of file type and a separate examination of file content that, when linked, demonstrate a mismatch. We determine that, in view of the Specification of the ’298 patent, one of ordinary skill in the art would interpret the “selecting” step of independent claims 1, 10, and 16 to include examining files “to determine whether the file structure is as expected for a file of the type indicated,” checking files “to ensure that they actually contain the type of data described by the file type marker,” and other, similar alternatives. Petitioner provides no reasoning that the Specification of the ’298 patent further describes separate examinations that demonstrate a mismatch. Petitioner’s arguments, therefore, do not persuade us that the broadest, reasonable interpretation of the “selecting” step in view of the Specification of the ’298 patent further includes “a sequence of linked examinations of the indicated file type and file content that demonstrates a mismatch.” Finally, an interpretation of the “selecting” step that includes “a sequence of linked examinations of the indicated file type and file content that demonstrates a mismatch” would render meaningless, or superfluous, the term “matches” as recited by independent claims 1, 10, and 16. Separate examinations of file type and file content that demonstrate a mismatch allows for no matching at all. Thus, Petitioner does not persuade us to adopt this particular interpretation of the “selecting” step.” slip op. at 5
