The Board denied institution because neither petition showed a reasonable likelihood that claims 1, 9, 10, 12, 30, 32, 42, or 45 were unpatentable over Kitamura or Mehrotra.

“We review the Petitions under 35 U.S.C. § 314, which provides that an inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Based on our review of the record, we conclude that neither Petitioner is reasonably likely to prevail in demonstrating that at least one of the challenged claims is not patentable, based on the Petitions filed.

“Kitamura is largely silent as to the specific functioning of the D/A conversion circuit 10. Kitamura discloses that D/A conversion circuit 10 and A/D conversion circuit 13 “preferably share a voltage dividing element and a reference voltage supply (for the purpose of making their characteristics uniform),” and level differences to maximize the operating margin (Ex. 1010 ¶ 11), but does not disclose a “selection” between reference voltages or signals. Although Petitioners emphasize the obviousness of certain elements of the challenged claims (Pet. 25– 26), the obviousness of selecting a reference voltage versus outputting a voltage from a D/A conversion is not discussed. Indeed, Dr. Baker’s discussion is clear (Ex. 1003 ¶¶ 74–79) as to how the output voltages could be set, but it remains unclear how Kitamura itself suggests the examples proffered. The normal function of a D/A converter is not to select between reference voltages, but to render the digital input into analog form. We are not persuaded that Kitamura teaches or suggests the selection of one of a plurality of reference voltages in accordance with the input information, per the challenged claims. In addition, the Petitions fail to provide any rationale for why Kitamura’s disclosure of D/A conversion renders the selection of a reference voltage or signal obvious. For these reasons, Patent Owner’s contentions that Kitamura does not teach or suggest “reference voltage selecting means,” or equivalent elements, or “reference voltages,” per the challenged claims, are persuasive.

“Reference Voltage Selection Claim 1 recites “reference voltage selecting means for selecting one of a plurality of reference voltages,” with claims 9, 12, and 30 reciting “selecting device which selects one of a plurality of reference signals,” and claims 42 and 45 reciting “selecting one of a plurality of predetermined reference signals.” Petitioners acknowledge that the means-plus-function element in claim 1 is “governed by 35 U.S.C. § 112, ¶ 6,” and that the construction of the claim term in claim 1 “is applicable to claim terms” recited in claims 9, 12, 30, 42, and 45, discussed above. Pet. 5, 8. Petitioners assert that “the verify reference voltage select circuit 222 selects and provides such a reference voltage to the comparator,” and is the corresponding structure described in the specification. Id. at 56 (citing Ex. 1003 ¶¶ 4552). For purposes of this Decision, we construe the referenced claim terms according to that structure and apply the same to the analysis below. B.” slip op. at 6

“Reference Voltages” “Reference Signals” All of the independent claims of the challenged claims recite either “reference signals” or “reference voltages.” Petitioners emphasize that “a person of ordinary skill in the art would have interpreted these features to be broad enough to include and be met by either a digital reference voltage/ signal or an analog reference voltage/signal.” Id. at 10 (citing Ex. 1003 ¶¶ 53–58). For purposes of this Decision, we construe the reference voltages and signals terms as being met by either digital or analog reference voltages/signals, and apply that construction to the analysis below. slip op. at 7

- PTAB / AIA Trials › Other PTAB motions (exclude, strike, seal, additional discovery, rehearing)Granted
“The standard for granting a motion to seal is “good cause,” reflecting the strong public policy for making all information in inter partes review proceedings open to the public. 37 C.F.R. § 42.54. The moving party bears the burden of showing that the relief requested should be granted. 37 C.F.R. § 42.20(c). This includes showing that the information is truly confidential, and that such confidentiality outweighs the strong public interest in having an open record. See Garmin Int’l v. Cuozzo Speed Techs., LLC, Case IPR2012-00001, slip op. at 3 (PTAB Mar. 14, 2013) (Paper 36). Petitioner Micron has made a sufficient showing. Accordingly, the Motion to Seal Exhibit 1011 is granted.” slip op. at 15
