Office Action

§112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments, see claims and remarks filed 4/30/2026 with respect to 35 USC 103 have been fully considered and are persuasive. The 35 USC 103 of Claims 5-9, and 11-15 has been withdrawn. Claim Objections Claim 5 and 14 objected to because of the following informalities: Claim 14 is objected to because the term “disperser” appears to contain a typographical error. lacks clarity and appears inconsistent with the term “dispenser” recited elsewhere in the claims. It is unclear whether Applicant intended “disperser” or “dispenser.” Appropriate correction is required for consistency and clarity. Claim 14 is further objected to because the phrase “the bidirectional DC/DC convert of the bidirectional energy storage module” appears to contain a typographical error. It is unclear whether Applicant intended to recite “converter” instead of “convert.” Appropriate correction is required for clarity. Claim 5 objected to because the term "thereto" is grammatically unclear in the limitation “the charging gun of the at least one charging device through the DC/DC converter corresponding thereto." The term thereto could correspond to the charging gun or the at least one charging device; in light of specification ”corresponding thereto” is interpreted to refer to the at least one charging device. Appropriate correction is required. 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 5 and 15 (also claims 6-9, and 11-15 by virtue of dependence) are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as failing to set forth 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. Claim 5 is rejected as being indefinite because the phrase “the second battery” lacks proper antecedent basis and renders the scope of the claim unclear. Specifically, claim 5 recites “a battery” within the bidirectional energy storage module, but does not previously introduce a “second battery” prior to reciting “the second battery.” Therefore, it is unclear what structure is being referenced by “the second battery.” Claim 15 is rejected as being indefinite because the phrase “the second bidirectional DC/DC converter” lacks proper antecedent basis and renders the scope of the claim unclear. Claim 5 recites “a bidirectional DC/DC converter” associated with the bidirectional energy storage module, but does not introduce a first and second bidirectional DC/DC converter prior to the recitation in claim 15. Therefore, it is unclear which converter is intended by “the second bidirectional DC/DC converter.” Allowable Subject Matter Claim 5-9, and 11-15 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.
