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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Response to Amendment The amendment filed 2/5/2026 has been entered. Claims 1, 3-7, 9-13 and 15-18 are pending. Claim Objections Claims 1, 3-7, 9-13 and 15-18 are objected to because of the following informalities: Regarding claim 7, the “a network device” in line 4 is unclear as to whether this device is the same or different network device as the “a network device” of line 3. Examiner suggests changing the “a” back to “the” to parallel the other sets of claims. Regarding claims 1, 7 and 13, “such that a power ramping counter corresponding to transmit powers of the N’ third spatial filters…” is unclear as to whether the “a power ramping counter” is a third power ramping counter or the first/second ramping counter(s). 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 1, 3-7, 9-13 and 15-18 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. Claim 1 recites the limitation "the second spatial filter" in line 20. There is insufficient antecedent basis for this limitation in the claim. The other independent clams and some of the dependent claims such as claim 3 also have the same antecedent basis problem. Response to Arguments Applicant’s arguments, see remarks, filed 2/5/2026, with respect to the claim objections and the rejections of pending claims under 112 and 103 have been fully considered and are persuasive. Therefore, the rejections and objections have been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of antecedent basis problem introduced by the amendments. 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.
