Office Action

§112 §DP
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 . 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 8 and 16 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 8 recites the limitation "the inter-polarization co-phasing value Cl" in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 16 recites the limitation "the inter-polarization co-phasing value Cl" in line 4. There is insufficient antecedent basis for this limitation in the claim. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-2, 4, 9-10, 12, 17-18 and 20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5, 8-12, and 15-19 of copending Application No. 19/051,038 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other. Independent Claims (instant application) 1, 9 and 17 are combinations of claims 1 and 5 (US 19/051,038 co-pending), claims 8 and 12 claims (US 19/051,038 co-pending), claims 15 and 19 (US 19/051,038 co-pending), respectively, and substantially disclose the corresponding claim limitations as highlighted in the table above (see mapping below). As can be seen, the slight difference is that the instant claim recites “a channel state information (CSI) report, the information indicating an antenna port group” in lieu of “a channel state information (CSI) report, the information indicating (i) codebookType set to ‘typeI-SinglePanel-r19’, (ii) codebookMode set to either ‘ModeA’ or ‘ModeB’, and (iii) P.sub.CSI-RS CSI reference signal (CSI-RS) antenna ports” recited in claims of the Co-Pending Application 19/051,038. The minor difference would be obvious to one skilled in the art since each of the respective elements perform the same function. The obvious variation in the wording does not change claim scope. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 18/912,509 (instant) 19/051,038 (co-pending) 1.

Regarding Independent Claim 4 (instant application), claim 2 or 3 (19/051,038 co-pending), substantially, discloses the corresponding claim limitations. Regarding Independent Claim 10 (instant application), claim 9 (19/051,038 co-pending), substantially, discloses the corresponding claim limitations.

Regarding Independent Claim 20 (instant application), claim 17 or 18 (19/051,038 co-pending), substantially, discloses the corresponding claim limitations. -------Claims 1, 3, 9, 11, 17 and 19 are also provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-2, 8-9 and 15-16 of copending Application No. 18/952,755 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Independent Claims 1, 9 and 17 (instant application), claims 1, 8 and 15, respectively (18/952,755 co-pending), substantially disclose the corresponding claim limitations as highlighted in the table above (see mapping below). As can be seen, the slight difference is that the instant claim recites “a channel state information (CSI) report, the information indicating an antenna port group” in lieu of “a channel state information (CSI) report, the information indicating: (i) an antenna port group, (ii) wideband (WB) or sub-band (SB) reporting, and (iii) a physical uplink control channel (PUCCH) format X” recited in claims of the Co-Pending Application 18/952,755. The minor difference would be obvious to one skilled in the art since each of the respective elements perform the same function. The obvious variation in the wording does not change claim scope. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 18/912,509 (instant) 18/952,755 (co-pending) 1.
