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 . Claim Objections A series of singular dependent claims is permissible in which a dependent claim refers to a preceding claim which, in turn, refers to another preceding claim. A claim which depends from a dependent claim should not be separated by any claim which does not also depend from said dependent claim. It should be kept in mind that a dependent claim may refer to any preceding independent claim. In general, applicant's sequence will not be changed. See MPEP § 608.01(n). Claims 15, 16, 17, and 18 are objected to because of the following informalities: because Claims 15, 16, 17, and 18 are depending on non-existing claim 21. For purpose of compact prosecution, claims 15, 16, 17, and 18 will be treated as if it were depending from Claim 1. Appropriate correction is required. 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 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,903,655 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because application claims 1-20 are anticipated by claims 1-20 of the patent, and it is not patentably distinct from claims 1-20 of the patent. Please, see the Table as shown below: Under Examination Claims Patented Claims 1.

Allowable Subject Matter Claims 1-20 are allowed if the above Doble Patenting rejection and claim objection overcomes. The following is an examiner’s statement of reasons for allowance: The primary reason for the allowance of the claim is the inclusion of the limitation “manufacturing a personalized spinal implant configured to be implanted in the subject, the manufacturing being based on the simulated spinal implant; and providing the personalized spinal implant for implantation into the subject” as recited in independent claim 1, in all of the claims which is not found in the prior art references. Claims 2-18 are allowed for the same reasons as claim 1, from which they depend. The primary reason for the allowance of the claim is the inclusion of the limitation “manufacturing a personalized spinal implant configured to be implanted in the subject, the manufacturing being based on the designed simulated implant; and providing the personalized spinal implant for implantation into the subject” as recited in independent claim 19, in all of the claims which is not found in the prior art references. The primary reason for the allowance of the claim is the inclusion of the limitation “manufacturing a personalized spinal implant configured to be implanted in the subject, the manufacturing being based on the designed simulated implant; and providing the personalized spinal implant for implantation into the subject” as recited in independent claim 20, in all of the claims which is not found in the prior art references.
