Office Action

§102
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. Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 10,751,181. Although the claims at issue are not identical, they are not patentably distinct from each other because the examined application claims are anticipated by the patent claims. Specifically, the patent claims also recite a temporary aortic valve apparatus comprising: a catheter shaft adapted to be advanced through a vasculature of a patient for placement within an aorta of the patient (Col 16 lines 37-40); and a flexible occluding membrane having a lateral side coupled to the catheter shaft (Col 16 lines 41-42) and adapted to alternate between an expanded occluding configuration and a collapsed lesser occluding configuration in the aorta in synchrony with ventricular diastole and systole (Col 16 lines 42-47). Claim Rejections - 35 USC § 102 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. 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. Claim(s) 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Strecker (US 2007/0118209). Regarding claim 1, Strecker discloses a temporary aortic valve apparatus comprising: a catheter shaft (36, FIG 5, [0046 and 0048]) adapted to be advanced through a vasculature of a patient (14, FIG 4) for placement within an aorta of the patient (Abstract discloses placement of the valve within the aorta, therefore it is understood the delivery catheter would be at least adapted for placement within the aorta); and a flexible occluding membrane (20, FIG 1, 3A, 3B, 5, [0037]) having a lateral side coupled to the catheter shaft (FIG 5 shows the valve housed within sheath 36, [0048]; wherein a lateral side is coupled by at least frictional contact) and adapted to alternate between an expanded occluding configuration (FIG 1) and a collapsed lesser occluding configuration (FIG 3A-3B, [0041-0043]) in the aorta in synchrony with ventricular diastole and systole (See fluid flow 24, FIG 3A, which occurs during systole and creates the collapsed, lesser occluding configuration, [0042]. During diastole, an absence of flow 24, the membrane returns to the expanded occluding configuration). Additional pertinent prior art Boretos (US 4,056,854) discloses a temporary aortic valve apparatus (11) comprising: a catheter shaft (20) and a flexible occluding membrane (18) adapted to alternate between an expanded occluding configuration (FIG 4A) and a collapsed lesser occluding configuration (FIG 4B) in the aorta in synchrony with ventricular diastole and systole (Col 2 lines 13-18 and col 3 lines 46-56).
