Office Action

§DOUBLEPATENT
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 . DETAILED ACTION 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 1-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 5-12 of U.S. Patent No. US 11038645 B2 in view of US 20150341942 A1 to Lee; Heun-Chul et al.. Although the claims at issue are not identical, they are not patentably distinct from each other because: Claim(s) 1 of the instant application merely broaden the scope of claim(s) 1 and 9 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993). The instant claim further differs from the patent claims in that each component comprises one or more resource elements that are located within a time-frequency grid. However, attention is directed to Lee, which, prior to the filing of the patent, discloses (Figs. 3 and 7 and 0056) that a CSI-RS pattern comprises resource elements in a time-frequency grid. Therefore, it would have been obvious to one or ordinary skill in the art at the time of the filing of the patent to have further utilized time-frequency grid for allocation of CSI-RS resources. The motivation for the combination is given by Lee (see Abstract and 0003). Claim 2 of the instant application is substantively the same and/or readily derivable from patent claim(s) 5. Claim 3 of the instant application is substantively the same and/or readily derivable from patent claim(s) 6. Claim 4 of the instant application is substantively the same and/or readily derivable from patent claim(s) 7. Claim 5 of the instant application is substantively the same and/or readily derivable from patent claim(s) 8. Claim 6 of the instant application is substantively the same and/or readily derivable from patent claim(s) 10 Claim 7 of the instant application is substantively the same and/or readily derivable from patent claim(s) 11.. Claim(s) 8 of the instant application merely broaden the scope of claim(s) 1 and 9 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993).

Claim 10 of the instant application is substantively the same and/or readily derivable from patent claim(s) 10. Claim 11 of the instant application is substantively the same and/or readily derivable from patent claim(s) 11. Claim(s) 12 of the instant application merely broaden the scope of, and is substantively derivable from, claim(s) 1 and 9 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993).

Claim 14 of the instant application is substantively the same and/or readily derivable from patent claim(s) 7. Claim 15 of the instant application is substantively the same and/or readily derivable from patent claim(s) 8. Claim 16 of the instant application is substantively the same and/or readily derivable from patent claim(s) 12. Claim 17 of the instant application is substantively the same and/or readily derivable from patent claim(s) 10. Claim 18 of the instant application is substantively the same and/or readily derivable from patent claim(s) 11. Claim(s) 19 of the instant application merely broaden the scope of, and is substantively derivable from, claim(s) 1 and 9 of the patent.

Claim 21 of the instant application is substantively the same and/or readily derivable from patent claim(s) 10. Claim 22 of the instant application is substantively the same and/or readily derivable from patent claim(s) 12. Claims 1-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8, 10-18 of U.S. Patent No. US 10516513 B2 in view of Lee. Although the claims at issue are not identical, they are not patentably distinct from each other because: Claim(s) 1 of the instant application merely broaden the scope of claim(s) 1 and 6 of the patent.

Claim(s) 19 of the instant application merely broaden the scope of claim(s) 26 and 25 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993). The instant claim further differs from the patent claims in that each component comprises one or more resource elements that are located within a time-frequency grid. However, attention is directed to Lee, which, prior to the filing of the patent, discloses (Figs. 3 and 7 and 0056) that a CSI-RS pattern comprises resource elements in a time-frequency grid. Therefore, it would have been obvious to one or ordinary skill in the art at the time of the filing of the patent to have further utilized time-frequency grid for allocation of CSI-RS resources. The motivation for the combination is given by Lee (see Abstract and 0003). Claim 20 of the instant application is substantively the same and/or readily derivable from patent claim(s) 32. Claim 21 of the instant application is substantively the same and/or readily derivable from patent claim(s) 23. Claims 1-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8, 10-17 of U.S. Patent No. US 12149473 B2 in view of Lee. Although the claims at issue are not identical, they are not patentably distinct from each other because: Claim(s) 1 of the instant application merely broaden the scope of claim(s) 1 and 6 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993).

The motivation for the combination is given by Lee (see Abstract and 0003). Claim 2 of the instant application is substantively the same and/or readily derivable from patent claim(s) 2. Claim 3 of the instant application is substantively the same and/or readily derivable from patent claim(s) 3. Claim 4 of the instant application is substantively the same and/or readily derivable from patent claim(s) 4. Claim 5 of the instant application is substantively the same and/or readily derivable from patent claim(s) 5. Claim 6 of the instant application is substantively the same and/or readily derivable from patent claim(s) 7. Claim 7 of the instant application is substantively the same and/or readily derivable from patent claim(s) 8. Claim(s) 8 of the instant application merely broaden the scope of claim(s) 1 and 6 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993).

Claim 10 of the instant application is substantively the same and/or readily derivable from patent claim(s) 7. Claim 11 of the instant application is substantively the same and/or readily derivable from patent claim(s) 8. Claim(s) 12 of the instant application merely broaden the scope of claim(s) 10 and 16 of the patent. It is well settled that broadening the scope of claims would have been obvious to one of ordinary skill in the art in view of the narrower issued claims. In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982) and In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993).

Claim 14 of the instant application is substantively the same and/or readily derivable from patent claim(s) 12. Claim 15 of the instant application is substantively the same and/or readily derivable from patent claim(s) 13.
