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 . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy of CN202410802963.7 filed on 06/20/2024 has been received/retrieved by the office. Information Disclosure Statement The information disclosure statement (IDS) submitted on 05/30/2025 has been considered by the examiner. Claim Objections Claims 1-7 are objected to because they include reference characters which are not enclosed within parentheses. Reference characters corresponding to elements recited in the detailed description of the drawings and used in conjunction with the recitation of the same element or group of elements in the claims should be enclosed within parentheses so as to avoid confusion with other numbers or characters which may appear in the claims. See MPEP § 608.01(m). Claim Rejections - 35 USC § 112 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 1-7 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. Regarding claim 1, the claim recites “a feedback” on lines 6, 13 and 18 which renders the claim indefinite, as the term presents improper antecedent basis, and unclear whether they are the same feedback signal or different feedback signal. Regarding claim 1, the claim recites “a current compensation module, configured to change signal magnitude fed back to the control module…” which renders the claim indefinite, as the claim recites more than one feedback provided to the control, for example “a feedback to a control module” recited on line 6, “a feedback to the control module” recited on line 13 and “a feedback to the control module” recited on line 18. Regarding claims 1-7, the claim recites various components followed by reference characters, which renders the claim indefinite as the reference characters are not used to distinguished between the different element. The examiner suggest amending the claims to specifically distinguish between the various components, for example, a first transistor (Q5), a second transistor (Q6), a first resistor (R15), a second resistor (R16), a gate of the first transistor (Q5) and so on. Allowable Subject Matter Claim 1 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 2-7 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 ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
