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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the contact assemblies of claims 1 and 8, the fixed part of claims 5 and 6, the transmission mechanism of claim 12, and the first power supply terminal, second power supply terminal and load terminal or claim 17 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). 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 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 1-17 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 regard to claims 1 and 8, “the first power supply” and “the second power supply” in lines 8 and 15, respectively lack antecedent basis. In regard to claim 7, “the second actuator” on line 2 lacks antecedent basis. In regard to claim 11, “the charging main shaft” on line 2 lacks antecedent basis. In regard to claims 14 and 15, claim 14 is dependent on itself rendering the dependency unclear. For the purposes of examination, claim 14 is interpreted as being dependent on claim 13. In regard to claim 17, it is unclear if “a first power supply” is the same as “the first power supply” in claim 1 or a different first power supply, if “a second power supply” is the same as “the second power supply” in claim 1 or a different second power supply, and if “a load” is the same load in claim 1 or a different load. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Huang et al. [US 2025/0125101 and US 2024/0312733] and Li et al. [US 2024/0339270] disclose similar apparatuses.
