Office Action

§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 . Specification The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. 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 2-10 and 12-21 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 4, 7, 8, and 14-20 of U.S. Patent No. 11,996,821. Although the claims at issue are not identical, they are not patentably distinct from each other because the limitations of the claims within the reference application feature the same invention and are within the scope of the claims of the present application. Claim 2 is anticipated by claim 15. Claim 3 is anticipated by claim 14. Claim 4 is anticipated by claim 15. Claims 6-7 are anticipated by claim 17. Claim 8 is anticipated by claim 18. Claim 9 is anticipated by claim 19. Claim 10 is anticipated by claim 20. Claims 12-19 are anticipated by claims 14-20. Claims 20-21 are directed to the surface acoustic wave device in a filter and the packaging of such elements. The configuration would not depart from the scope of the patented invention. Claim 11 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 14-15 of U.S. Patent No. 11,996,821 in view of Bhattacharjee et al. (US20170288629). Claim 15 of the ‘821 patent recites the limitations of claim 2 of the instant application, but fails to recite a second temperature compensating layer. Bhattacharjee discloses a silicon dioxide layer (42) between the piezoelectric substrate (30) and the silicon substrate (28) to change one or more operating parameters of the acoustic wave device, such as to increase thermal performance. Therefore, it would have been obvious to one with ordinary skill in the before the effective filing date of the instant application to provide another temperature compensating layer between the piezoelectric layer and the silicon substrate to increase the thermal performance of the device. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892.
