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 . Response to Amendment Upon consideration, the previous rejection of record was withdrawn in light of new amendments. However new rejection is applied to the amended claims. All changes made in the rejection are necessitated by the amendment. Response to Arguments Applicant’s arguments with respect to claim(s) 1 and 4-11 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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 and 4-11 is/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. The recitation “…further comprising: an upper housing…cover upper surfaces…of the first module and the second module…” in dependent claim 8 is unclear because claim 1 also recites “…an upper housing coupled to each of the pair of foldable side plates to cover upper surfaces of the first module and the second module…” Examiner submits that both claims 1 and 8 appear to teach the same upper housing but such recitation can be construed as two different upper housings. Examiner recommends an amendment to dependent claim 8. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: The cited prior art does not specifically teach a pair of foldable side plates configured to form an enclosure around the around the cell stacks and maintain a continuous pressurization force across the cell stacks during a transition from folded to unfolded condition. In addition, Examiner recommends canceling the withdrawn claim 12 (see Restriction mailed 08-09-2023 and Applicant’s Response filed 10-06-2023). 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.
