The Board cancelled claims 1–27 and denied substitute claims 28–51 because the original disclosure lacked written-description support for the claimed CSP limitations.
RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“In our Institution Decision, we adopted Petitioner’s proposed level of ordinary skill in the art, with the exclusion of “at least” because it introduces ambiguity. Inst. Dec. 8. Patent Owner “does not dispute the Board’s findings on the qualifications of a POSA [person of ordinary skill in the art] for purposes of this proceeding.” See RMTA 13. We determine that Petitioner’s definition, with the exclusion of “at least,” is consistent with the prior art of record and the skill reflected in the Specification of the ’034 patent and we use this level of skill here in the evaluation of the Revised Motion to Amend.” slip op. at 9
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for patent owner
“Patent Owner argues that “claim construction is not necessary” and that “the meaning of the claims would be easily understood by a POSA.” RMTA 13. In the Petition, Petitioner proposed constructions for the terms “client device” and “first server,” and the original claims were rendered obvious under this construction. Pet. 23–27. Petitioner does not assert that the substitute claims of the Revised Motion to Amend are anticipated or rendered obvious by prior art or are patent ineligible. See generally RMTA Opp. Nor does Petitioner’s patentability challenge of the substitute claims contend that express construction is needed. See generally id. For purposes of this Decision, we determine that express claim construction is unnecessary. We need only construe terms that are necessary to resolve disputes. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”).” slip op. at 10

The issue here, however, is whether the disclosure of the ’034 patent would have reasonably conveyed to a person of ordinary skill that the inventors had possession of the CSP Limitations.

The Board granted cancellation of claims 1, 2, 5, and 9 but denied substitute claims 13–16 because the application lacked written description support for the added limitation.
RulingsFinal written decision- 112 supportMotion to amend, deniedDenied
“Under the correct test for compliance with the written description requirement, Patent Owner’s arguments and evidence do not establish that the ’642 application provides written description support for a variable current limit threshold increasing “during at least a portion of the first state.” The only embodiment disclosed in the ’642 application shows a current limit threshold that increases during the entire on time of the switch (i.e., the entire first state), and the ’642 application never describes a current limit threshold that increases during only a portion of the on time of the switch. Patent Owner’s Motion to Amend and Dr. Kelley’s declaration testimony in support thereof rely exclusively on portions of the ’642 application describing a threshold that increases throughout the on time of the switch. See Mot. 10–13; Ex. 2010 ¶¶ 62–65. Patent Owner and Dr. Kelley do not specifically address the “at least a portion of” claim language and thus fail to explain adequately how the disclosure of a threshold that increases throughout the on time of the switch would reasonably convey to a person having ordinary skill in the art that the inventor had possession of a current limit threshold that increases for “at least a portion of” the first state. Therefore, Patent Owner’s arguments and submitted testimony are unsupported and conclusory with regard to written description support for the “at least a portion” language, and indeed are inconsistent with the disclosure in the ’642 application, which provides support only for a current limit threshold that increases during the entire first state.” slip op. at 22
- Skill levelSkill level patent owner adoptedDecided for patent owner
“Owner asserts that a person of ordinary skill in the art at the time of the invention of the ’605 patent “would have had a bachelor’s degree in electrical engineering, physics, or a related discipline, and at least two to three years of relevant experience in the field of power electronics or similar circuitry.” Mot. 3 (citing Ex. 2010 ¶ 22). Patent Owner further asserts that “[a]dditional education, such as an advanced degree in electrical engineering or a related field, might substitute for some of the experience, and substantial experience might substitute for some of the educational background.” Id. (citing Ex. 2010 ¶ 22). Petitioner’s declarant, Dr. Douglas Holberg, has a similar view, opining that a person of ordinary skill in the art at the time of the invention would have had “a B.S. in Electrical Engineering or a related field with at least two years of experience in designing power electronics,” or “an M.S. in Electrical Engineering or a related field.” Ex. 1003 ¶ 38. The two formulations do not differ in any material way. Based on our review of the record, we agree with the parties as to the level of ordinary skill in the art. For purposes of analyzing the Motion to Amend, we specifically adopt Patent Owner’s definition of a person of ordinary skill in the art. See Mot. 3; Ex. 2010 ¶ 22.” slip op. at 14
- Expert testimonyPatent owner expert discountedDecided for petitioner
“We disagree for two reasons. First, under Aqua Products, as explained further in the Office’s post-Aqua Products guidance document, a patent owner must still meet the statutory and regulatory requirements for a motion to amend, including setting forth written description support for amended claims, which must not introduce new matter. Aqua Prods., 872 F.3d at 1305–06; Guidance 2. Second, Dr. Kelley’s conclusion that the ’642 application provides written description support for “the variable current limit threshold increases during at least a portion of the first state of each control signal cycle” is conclusory and inconsistent with the intrinsic evidence (i.e., the ’642 application itself), and we therefore give his testimony on this point little weight.” slip op. at 23
