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 . 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 rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,906,235 (‘235) in view of U.S. Patent Application Publication 2011/0041411 to Aragon (Aragon). In reference to claim 1, ‘235 claims a refrigeration door system with a defrosting feature, the refrigeration door system comprising a housing defining a refrigerated cavity therein (claim 1, line 3); and a door assembly carried by the housing and providing access to the refrigerated cavity (claim 1, line 4); the door assembly comprising a door frame and door coupled to the door frame, the door switching between an open position providing the access to the refrigerated cavity and a closed position where the refrigerated cavity is inaccessible (claim 1, lines 6-11), the door frame comprising a top member having a first end and a second end opposite the first end (claim 1, lines 13-14), the top member having a top conduit therein (claim 1, line 23), a first side member coupled transversely to the first end of the top member and having a first conduit therein, the first conduit being fluidly coupled to the top conduit (claim 1, lines 15-17), a second side member coupled transversely to the second end of the top member and having a second conduit therein, the second conduit being fluidly coupled to the top conduit (claim 1, lines 18-19), a plurality of orifices positioned along the first side member and the second side member and being adjacent to the door when in the closed position (inherent; air must be conveyed from the pressure source and through the conduits into the channels within the door members), at least one positive pressure source fluidly coupled to the top member and configured to output air into at least first and second conduits and through the plurality of orifices (claim 8), and at least one heating device configured to heat the air from the at least one positive pressure source (claim 8), but does not claim a plurality of gasket pieces carried by the first side member and the second side member, the plurality of gasket pieces being spaced apart and defining an air channel between each of the first side member and the second side member and adjacent portions of the door.
