Office Action

§DP
FIRST NON-FINAL REJECTION 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. Claims 1-13 rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 11,963,453. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant invention is currently met as set forth or obvious is in view of the patented claims. The table below details that instant inventions claims and the corresponding patented claim that meets the claimed subject or is obvious in view of. Instant Invention Claim Corresponding Patented Claim 1 1 2 1 3 2 4 3 5 1 6 4 7 5 8 6 9 7 10 8 11 9 12 10 13 1 Claim 14 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 11,963,453 in view of Lee et al. U.S. Patent Application Publication 2014/0299840. The Patent teaches the claim subject matter except wherein the first carbon-based material comprises one or more materials providing negative charges, and the second carbon-based material comprises one or more materials providing negative charges. Lee teaches a graphene laminate includes a first piezoelectric material layer having a negatively-charged surface and a positively-charged surface, a first graphene layer under the first piezoelectric material layer, the first graphene layer contacting the positively-charged surface of the first piezoelectric material layer, a second graphene layer underlying the first graphene layer, and a second piezoelectric material layer under the second graphene layer, the second piezoelectric material layer having a negatively-charged surface and a positively-charged surface, the negatively-charged surface contacting the second graphene layer (abstract). Accordingly, it would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the invention of patented claims and provide a structure layers having negative charges as taught by Lee in order to provide a sensor with relatively high charge mobility (paragraph 9, Lee).
