Office Action

§DP
CTNF 19/395,970 CTNF 82576 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 07-06 AIA 15-10-15 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 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. 07-30-03-h AIA CLAIM INTERPRETATION The presence of claim limitations that are preceded by the phrases “wherein” often raises a question as to the limiting effect of the claim limitations (see MPEP §2111.04). The Examiner has interpreted the limitations following the phrase “wherein” as positively being claimed (i.e. the claim limitations are required and/or the claim limitations following the “wherein clause” limits the structure), where “wherein” is being used as a transitional phrase. Double Patenting 08-33 AIA 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. 08-34 AIA Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim 2 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 2 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim 3 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 3 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim 6 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 5 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim 7 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 6 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim 8 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 7 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim . 08-34 AIA Claim s 9 and 10 are each rejected on the ground of nonstatutory double patenting as being unpatentable over claim 15 of U.S. Patent No. 12,503,969 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because the current claim is broader in scope to the patented claim, where claim 15 includes the bisecting plane between 20 to 60 degrees, where “less than 50 degrees” is an overlapping range that was claimed in U.S. Patent No. 12,503,969 B2 . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 4 and 5 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. 12-151-07 AIA 07-97 12-51-07 Claim s 11-20 are allowed.
