Office Action

§102 §103 §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 . DETAILED ACTION This is a non-final First Office Action on the Merits in application 18/798,103, filed 8/8/2024, which is a continuation as discussed in the disclosure. The substitute specification filed 10/23/2024 has been entered. Claims 1-29 are pending and examined. Information Disclosure Statement The information disclosure statement (IDS) submitted on 8/8/2024 is being considered by the examiner.

Claim Objections Claims 3-5, 7-8, 11-12, 14-19, 21, 25-26 and 28-29 are objected to because of the following informalities: in claims 3-4, 7-8, 12, 16-17 and 21, “each member” should be “each of the members”, in claims 3, 7, 11-12, 14-18, 21, 25-26 and 28-29, “an adjacent member” should be “an adjacent one of the members”; and in claims 5 and 19, “string” should be “the string”. Appropriate correction is required. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2 and 11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kirby(U.S. Pat. Appl. Publ. 2019/0186198; cited on IDS filed). Regarding claims 1-2, Kirby discloses a manually operated window treatment system(10, see para. [0014]), comprising: a roller tube(12) that is supported at opposed ends thereof(16, see para. [0015] and Fig. 1); a covering material(14, see para. [0014]) that is attached to the roller tube(see Fig. 1), the covering material operable between a raised position and a lowered position via rotation of the roller tube; and a chain(100) configured to be operated by a user to rotate the roller tube, the chain including a plurality of members(110, see Fig. 2-7) joined in a continuous loop(see Figs. 2-4), wherein the chain has a first minimum bend radius(R1, see para. [0019] and Fig. 4) when bent in a first direction(bent upwardly, see Figs. 2-4) and a second minimum bend radius(top radius, see para. [0019]) when bent in a second direction(bent downwardly, see Figs. 2-4), and wherein the first minimum bend radius(R1) is less than the second minimum bend radius(see para. [0019]). Regarding claim 11, Kirby discloses the chain of claim 2, wherein each of the plurality of members(114) comprises a body(116, see Figs. 5-8) and an arm(114 or 132) extending from the body, and wherein the arm of each of the plurality of members is coupled to a body of an adjacent member. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 3, 17 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Kirby. Kirby discloses the chain of claim 2, wherein each member of the chain is configured to contact an adjacent one of the members of the chain to restrict bending of the chain in the second direction such that a minimum bend radius of the chain in the second direction is greater than or equal to a specific length but lacks the specific length. Applicant’s disclosure lends no criticality to the specific bend radius(see paras. [0005], [0019], [0021], [0066] and [0085]). Therefore, the specific bend radius is considered a feature best determined by a skilled artisan given the intended use of the chain and specific design requirements thereof, such as sprocket size. Regarding claim 25, Kirby discloses the chain of claim 17, wherein each of the plurality of members(114) comprises a body(116, see Figs. 5-8) and an arm(114 or 132) extending from the body, and wherein the arm of each of the plurality of members is coupled to a body of an adjacent member. 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.
