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 21-40 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12,253,329. Although the claims at issue are not identical, they are not patentably distinct from each other because the application claims are generic to all that is recited in the patent claims. In other words, the patent claims fully encompass the subject matter the application claims and therefore anticipate the application claims. Since the applications claims are anticipated by the patent claims, they are not patentably distinct from the patent claims. Thus the invention of the patent claims are in effect a “species” of the “generic” invention of the application claims. It has been held that the generic invention is anticipated by the species, see In re Goodman, 29 USPQ2d 2010 (Fed. Cir. 1993). Since the application claims are anticipated (fully encompassed) by the patent claims, the application claims are not patentably distinct from the patent claims, regardless of any additional subject matter present in the patent claims. Allowable Subject Matter Claims 21-40 are allowable over the prior art except for the Double Patenting rejection. The following is a statement of reasons for the indication of allowable subject matter: the prior art of record fails to disclose or fairly suggest the claimed handguard assembly for a firearm, the handguard assembly comprising: an outer member; a heat shield; and at least one engagement feature for securing the heat shield relative to the outer member, wherein: the at least one engagement feature comprises at least one protrusion integrally formed as part of the outer member and at least one recess in the heat shield. Furthermore, the prior art of record fails to disclose or fairly suggest the claimed firearm receiver assembly comprising: a receiver; a barrel; a first handguard assembly located forward of the receiver and adjacent to the barrel, the first handguard assembly comprising an outer member, a heat shield, and at least one engagement feature for securing the heat shield relative to the outer member; a second handguard assembly located forward of the receiver and adjacent to the barrel, the second handguard assembly comprising an outer member, a heat shield, and at least one engagement feature for securing the heat shield relative to the outer member, wherein: the at least one engagement feature of the first handguard assembly comprises at least one protrusion within an interior of the outer member and at least one recess in the heat shield; and the at least one engagement feature of the second handguard assembly comprises at least one protrusion within an interior of the outer member and at least one recess in the heat shield.
