Office Action

§112
DETAILED ACTION The present application, filed 01/15/2025, is being examined under the first inventor to file provisions of the AIA . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The abstract of the disclosure is objected to because it contains more than 150 words. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Drawings Figure 1 should be designated by a legend such as --Prior Art-- because only that which is old is illustrated. See MPEP § 608.02(g). Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections The claims 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 pre-AIA the applicant regards as the invention. Claim 1 recites the limitation "a capacitor" in lines 3, 5, 10, 12. There is insufficient antecedent basis for this limitation in the claim. It is suggested that the claim is amended to recite “a first capacitor”, “a second capacitor”, etc. Claim 1 recites the limitation "an inductor" in lines 7, 11-12, 17. There is insufficient antecedent basis for this limitation in the claim. It is suggested that the claim is amended to recite “a first inductor”, “a second inductor”, etc. Claim 1 recites the limitation "a pin" in lines 6, 9, 10, 13, 15. There is insufficient antecedent basis for this limitation in the claim. It is suggested that the claim is amended to recite “a first pin”, “a second pin”, etc. Claim 1 recites the limitation "an MOS transistor" in lines 6, 11. There is insufficient antecedent basis for this limitation in the claim. It is suggested that the claim is amended to recite “a first MOS transistor”, “a second transistor”, etc. Claim 2 recites the limitation "the capacitor". There is insufficient antecedent basis for this limitation in the claim. Claim 3 recites the limitation "the pin". There is insufficient antecedent basis for this limitation in the claim. Claim 4 recites the limitation "the pin". There is insufficient antecedent basis for this limitation in the claim. Claim 5 recites the limitation "the MOS transistor". There is insufficient antecedent basis for this limitation in the claim. Claim 6 recites the limitation "the inductor". There is insufficient antecedent basis for this limitation in the claim. Claim 7 recites the limitation "the pin", “the MOS transistor”, “the capacitor”, and “the inductor”. There is insufficient antecedent basis for this limitation in the claim. Claim 7 recites the limitation "a switch" in lines 6 and 7. There is insufficient antecedent basis for this limitation in the claim. It is suggested that the claim is amended to recite “a first switch”, “a second switch”, etc. Allowable Subject Matter Claims 1-7 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.
