Office Action

§DP
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 1-12 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7, 17 of U.S. Patent No. US 10,645,972. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims cover the same limitations. 18/790276 10,645,972 Claim 1: An aerosol-generating device comprising: a housing; an electrical power supply in the housing; a plurality of semiconductor heaters in the housing, each of the plurality of semiconductor heater including, a substrate layer, and a heating layer on the substrate layer, the heating layer of at least one of the plurality of semiconductor heaters including a semiconductor gas sensor such that the heating layer is a combined heating and gas sensing layer; and a controller configured to control a supply of electrical power from the electrical power supply to each of the plurality of semiconductor heaters, the controller configured to determine an amount of at least one gas based on a measured electrical resistance of the combined heating and gas sensing layer, and wherein the controller is configured to simultaneously: control a supply of electrical power from the electrical power supply to the combined heating and gas sensing layer so as to heat the semiconductor gas sensor; and determine an amount of at least one gas based on a measured electrical resistance of the combined heating and gas sensing layer. Claim 2: the housing defines a cavity. Claim 3: the plurality of semiconductor heaters are in the cavity. Claim 4: the cavity is configured to receive an aerosol-generating article. Claim 5: wherein the controller is configured to control the supply of electrical power to the combined heating and gas sensing layer in response to a determined amount of the at least one gas within the cavity. Claim 1: An aerosol-generating device comprising: an electrical power supply; a housing defining a cavity, the cavity configured to receive an aerosol- generating article; a plurality of semiconductor heaters positioned within the housing, each of the plurality of semiconductor heaters including, a substrate layer, and a heating layer on the substrate layer, the heating layer being a continuous layer; and a controller configured to control a supply of electrical power from the electrical power supply to each of the plurality of semiconductor heaters, wherein the heating layer of at least one of the semiconductor heaters is a combined heating and gas sensing layer, wherein the controller is configured to measure an electrical resistance of the combined heating and gas sensing layer to determine an amount of at least one gas within the housing, and wherein the controller is configured to simultaneously: control a supply of electrical power from the electrical power supply to the combined heating and gas sensing layer; and measure the electrical resistance of the combined heating and gas sensing layer to determine an amount of the at least one gas within the housing.
