Office Action

§101 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 1-20 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-27 of prior U.S. Patent No. 10,420,863. This is a statutory double patenting rejection. 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The 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/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-6 of U.S. Patent No. 11,065,369. Although the claims at issue are not identical, they are not patentably distinct from each other because both sets of claims comprise polymers crystallized with poly(L-lactide-co-tri-methylene-carbonate) or poly(D-lactide-co-tri-methylene-carbonate) or poly(L-lactide-co--caprolactone) or poly(D-lactide-co--caprolactone) in the form of block copolymers. The patented claims are a species of the instant claims. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 9,642,947. Although the claims at issue are not identical, they are not patentably distinct from each other because both sets of claims comprise polymers crystallized with poly(L-lactide-co-tri-methylene-carbonate) or poly(D-lactide-co-tri-methylene-carbonate) or poly(L-lactide-co--caprolactone) or poly(D-lactide-co--caprolactone) in the form of block copolymers. The patented polymer is a species of the instant claims. The instant claims are drawn to a scaffold, whereas the patented claims are drawn to a stent. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4 of U.S. Patent No. 9,662,416. Although the claims at issue are not identical, they are not patentably distinct from each other because both sets of claims comprise polymers crystallized with poly(L-lactide-co-tri-methylene-carbonate) or poly(D-lactide-co-tri-methylene-carbonate) or poly(L-lactide-co--caprolactone) or poly(D-lactide-co--caprolactone) in the form of block copolymers. The patented polymer is a species of the instant claims. The instant claims are drawn to a scaffold, whereas the patented claims are drawn to the polymer used to prepare the scaffold. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 4-13 of U.S. Patent No. 7,846,361 in view of Pohjonen et al. (US 6,607,548) and Hossainy et al. (US 2006/0041102). Although the claims at issue are not identical, they are not patentably distinct from each other because the patented claims recite a species of the polymer used to create a polymeric stent. The instantly claimed polymers do not recite specific percentages of each block, however, it would have been obvious to one of ordinary skill in the art to adjust the amounts of each block in order to obtain the desired mechanical and structural elements. Pohjonen and Hossainy discloses the combination of polymers can be used to prepare a stent. It would have been obvious to one of ordinary skill in the art at the time the invention was made to have used the polymeric blend of copending claims to make a stent since Pohjonen and Hossainy disclose the same polymers used in implantable devices and drug loaded stents. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 7-16, and 20-28 of U.S. Patent No. 7,959,942. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims are drawn to a species of the patented claims. The patented claims recite an implantable medical device, whereas the instant claims are drawn to a stent specifically. Additionally, the patented claims recite a species of the polymer used to create a polymeric stent. The instantly claimed polymers do not recite specific percentages of each block, however, it would have been obvious to one of ordinary skill in the art to adjust the amounts of each block in order to obtain the desired mechanical and structural elements. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7 of U.S. Patent No. 8,137,603. Although the claims at issue are not identical, they are not patentably distinct from each other because the copending claims are drawn to a method of preparing the scaffold of the instant claims. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5 of U.S. Patent No. 9,173,973. Although the claims at issue are not identical, they are not patentably distinct from each other because the copending claims are drawn to a method of preparing the scaffold of the instant claims. It is noted that there are numerous applications and issued patents with the same assignee, and one or both inventors. Applicant is requested to identify any additional Obviousness Double Patenting of which he/she may be aware.
