Office Action

§112
DETAILED ACTION Response to Amendment The amendment filed 8/13/2026 has been entered. The applicant has amended claims 1-10. Claims 1-10 remain pending in the application. The amendment has overcome all the objections and rejections set forth in the Non-Final Office Action mailed 6/4/2026 (“FAOM”), which are hereby withdrawn. Response to Arguments Applicant’s arguments, see pages 6-8 of the Remarks filed 8/13/2026 (“Remarks”), with respect to the objections and rejections of record have been fully considered and found persuasive. Therefore, those grounds of rejections have now been withdrawn. However, upon further consideration, new ground(s) of rejection(s) under 35 USC 112(b) have now been made, which were necessitated by the applicant’s amendment to claim 10. 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. Claim 10 is rejected under 35 U.S.C. 112(b), as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor, or a joint inventor, regards as the invention. Claim 10, as amended, recites “wherein a first phase shifter is formed in the upper hollow cavity and in the lower hollow cavity, and an input signal excites a radiation array through the first and second phase shifters, respectively.” There is insufficient antecedent basis for the term “second phase shifters.” To provide a proper antecedent basis, the examiner suggests revising as follows: --wherein a first phase shifter is formed in the upper hollow cavity and a second phase shifter is formed in the lower hollow cavity, and an input signal excites a radiation array through the first and second phase shifters, respectively-- Appropriate correction is required. Allowable Subject Matter Claims 1-9 are allowable for the reasons set forth in the FAOM at 4-5. Claim 10 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) set forth in this Office action and to include all of the limitations of the base claim(s) and any intervening claims. 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 extension fee 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 date of this final action.
