Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This is a response to the amendment filed 1/20/2026. Claims 1-17 are pending and are under examination. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-17 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. In this instant, the specification has failed to describe “wherein the controlling circuit further generate the voltage level signal configured to control the voltage chip to output a target voltage corresponding to the voltage regulating instruction” (claims 1 and 9) at the time the invention was filed. Claims 2-8 and 10-17 are also rejected under 35USC 112, first paragraph because of the technical deficiencies of claims 1 and 9. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-17 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. In claims 1 and 17, the recitation of “wherein the controlling circuit further generate the voltage level signal configured to control the voltage chip to output a target voltage corresponding to the voltage regulating instruction” is indefinite because it is not understood as to whether “the voltage signal level” is generated by the controlling circuit or the conversion circuit (lines 7-9 recites the conversion circuit generates the voltage signal level). The recitation of “a target voltage” (lines 11-12) is also unclear as to if this target voltage is the same as or is different from “a target level signal” recited in line 4. Thus, the metes and bounds of the claim cannot be determined renders the claim indefinite. In claim 3, the recitation of “the current supply voltage” (line 3) lacks proper antecedent basis. The recitation of “a target voltage” (line 2) is indefinite because it is unclear as to whether this target voltage is the same as or different from “a target voltage” or “a target level signal” recited in claim 1, lines 4 and 11. Thus, the metes and bounds of the claim cannot be determined renders the claim indefinite. In claim 8, the recitation of “the current supply voltage” (line 3) lacks proper antecedent basis. In claim 11, the recitation of “the current supply voltage” (line 3) lacks proper antecedent basis. Claims 2, 4, 5-7, 10-12 and 14-17 are also indefinite because of the technical deficiencies of claims 1 and 9. Allowable Subject Matter Claims 1-17 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 1st and 2nd paragraph, set forth in this Office action. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. In this regard, applicant’s cited prior art has been carefully considered.
