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 and 14 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of copending Application No. 18/094,734 in view of Brown et al. (US 2023/0151537). Copending application ‘734 anticipates current application claims 1 and 14, wherein the copending claimed tub is the same as the currently claimed drum because both have the same structure and function and the copending claimed heat flow to chamber anticipates the current application claim air handler because both move air in an enclosure. Brown obviates the copending claimed invention by teaching a lint collection assembly, as currently claimed, in paragraphs [0044]-[0045] wherein the disclosed agitation to remove foreign substrates meets the claimed knocking feature, since both mechanically remove lint in a filter cleaning device. It would have been obvious to one skilled in the art to combine the teachings of Brown with the copending claimed features, since the prior art in combination with the copending claims meets the current claimed invention. This is a provisional nonstatutory double patenting rejection. Allowable Subject Matter Claims 1-20 are allowable over the prior art of record because the dryer appliance and lint collection assembly with all the claimed features including a filter housing, frame, plenum mount with a filter cleaning mechanism periodically knocking off collected lint off the filter is not found in the prior art either singly or in combination. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Other prior art references cited with this application, may teach one or more claim features, but do not rise to a level of anticipation, obviousness, and/or double patenting such that a rejection would be proper and reasonable under current Office practice and procedure. References A, B, C, cited with this action, are patent publications from the same inventive entity. References D, E, F, G, H, I, J, K, L, M, N, O, cited with this action teach laundry appliances and/or lint collection assemblies.
