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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on February 18, 2026 has been entered. Response to Arguments Applicant's arguments with respect to claims 1-20, filed February 18, 2026, have been considered and are persuasive. As such, the rejection under 35 U.S.C. 103 for pending claims 1-20 has been withdrawn. However, claims 1-20 remain rejected under a provisional nonstatutory double patenting rejection as previously made of record and detailed below. 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 1-20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-32 of copending Application No. 17/880,937 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because Application ‘937 has been found to anticipate each and every element of the present invention for instance both providing a plurality of electrode elements comprising a metal layer, wherein the plurality of electrode elements occupy an area; and a first portion that contacts at least a first electrode element of the plurality of electrode elements; and a second portion that is positioned outwardly beyond the area occupied by the plurality of electrode elements, with a layer of anisotropic material and at least one conductive adhesive or gel layer and a second layer of anisotropic material and at least one conductive adhesive or gel layer; and a thermal barrier layer; wherein the layer of anisotropic material comprise a respective sheet of anisotropic material having a front face and a rear face, wherein: the sheet has a first thermal conductivity in a direction that is perpendicular to the front face, and thermal conductivity of the sheet in directions that are parallel to the front face is more than two times higher than the first thermal conductivity, or the sheet has a first resistance in a direction that is perpendicular to the front face, and resistance of the sheet in directions that are parallel to the front face is less than half of the first resistance. As set forth above, the present invention is not viewed to be patentably distinct from the co-pending application 18/193,923. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
