Office Action

§103
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 . 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. Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,082,142. Although the claims at issue are not identical, they are not patentably distinct from each other. Claim 1 of the instant Application conflicts with claim 1 of U.S. Patent No. 12,082,142. Claim 1 is anticipated by claim 1 of U.S. Patent No. 12,082,142. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over Aryan (2011/0170463). Regarding claim 1, Aryan discloses a method performed by a base station, the method comprising: (See Aryan para. 33; base stations; fig. 1, 4) transmitting a first round-trip time measurement signal having a first transmit group delay; (See Aryan fig. 5; Node B transmits a beacon (e.g. round trip time measurement signal) and measures its own TX and Rx chain delays (e.g. group delay); para. 8; round trip delay; see also para. 54-59) sending, to a receiving entity, information indicating the first transmit group delay (See Aryan fig. 5, para. 48-49; Node B transmits to Node A a beacon with embedded TX and RX chain delay) Aryan also discloses that receive chain and transmit chain delay may vary based upon current operating conditions, such as temperature, speed, frequency, packet size, SNR, etc. (See Aryan para. 29) Aryan does not explicitly disclose that the process may be performed multiple times (e.g. a second round trip time measurement signal and a second group delay). However, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the method of Aryan to include the teaching of that the process may be performed multiple times (e.g. a second round trip time measurement signal and a second group delay) with the motivation being it is common sense (Aryan already discloses that the delay may be affected by many factors so it may need to be tested multiple times across different times and frequencies) and further to ensure accurate positioning (which may assist in coordination of resources) and further for accurate navigation of mobile devices and further it is a duplication of parts under MPEP 2144.04 (performing Aryan’s known delay-measurement and reporting process a second time would predictably provide the receiving entity with delay information for a second RTT measurement signal. There is no new or unexpected results from performing a known process again) Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. R1-2006972 discloses on page 47, sending group delay to UE.
