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 10-12 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 and 10-12 of U.S. Patent No. 11,246,704. Although the claims at issue are not identical, they are not patentably distinct from each other both claiming a method for assembling a prosthetic valve wherein the current claims are broader versions of the patented claims. Patented claim 1 claims at least the frame assembly and ventricular legs and claim 10 claims all limitations of a piece of flexible material being flat and defining a belt with strips. All other method steps of forming a pocket by folding the strips and stitching together of the first edge and second edge, subsequently, dressing the frame assembly with the of flexible material (third sheet) and sliding each leg into a respective pocket and wrapping the belt around a tubular portion of the valve are found in claim 10. Patented claim 11 corresponds to current claim 11. Patented claim 12 corresponds to current claim 12. Priority This application is claiming the benefit of prior-filed PCT/IL2018/050725, however, a copy is not found in the application and the examiner was unable to obtain a copy. For this action, the examiner assumes that said PCT supports all limitations found in U.S. application 16/776,581 which is the earliest date which support of the claims. Allowable Subject Matter Claims 17-20 and 147-151 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 10-12 would be allowable upon the submitting to a proper terminal disclaimer. The following is an examiner’s statement of reasons for allowance: The prior art of record fails to teach a method for assembling a prosthetic valve comprising: obtaining a piece of flexible material, the piece being flat, and shaped to define (i) a belt, and (ii) a plurality of elongate strips, each of the strips (i) having a first edge, a second edge, and an end, and (ii) extending from the belt along a respective strip-axis until the end, the first edge and the second edge extending, on either side of the strip-axis, from the belt to the end of the strip; for each of the strips, forming the strip into a respective pocket by: folding the strip over itself, about a fold-line that is orthogonal to the strip-axis, thereby forming (i) a first strip-portion that extends from the belt to the fold-line, and (ii) a second strip-portion that extends from the fold-line back toward the belt; and stitching together (i) the first strip-portion at the first edge, and the second strip-portion at the first edge, and (ii) the first strip-portion at the second edge, and the second strip-portion at the second edge, the pocket having (i) an opening defined at least in part by the end of the strip, and (ii) a tip at the fold-line; and subsequently, dressing the frame assembly with the piece of flexible material by: sliding each leg into a respective pocket via the opening of the respective pocket; and wrapping the belt circumferentially around the tubular portion. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Any inquiry concerning this communication or earlier communications from the examiner should be directed to BRUCE EDWARD SNOW whose telephone number is (571)272-4759.
