Office Action

§102 §112
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 . Response to Arguments The amendments, dated 5/13/2026, have overcome: The objection(s) to claim(s) 10, 15, 6, 13, 18; The rejection of claim(s) 6-9, 13-19 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph; The rejection of claim(s) 1-20 under 35 U.S.C. 102(a)(1) and 35 U.S.C. 102(a)(2) based on Duggal et al. (US 2011/0166609 A1 – as previously cited); The aforementioned objections/ rejections have been withdrawn. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim(s) 6, 12-19, 21 is/are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Within claim 6, line 1: Applicant claims, “the bottom portion”; it is unclear, and therefore indefinite, which bottom portion is being referred to – the bottom portion of the first implant component or the second implant component? For the purposes of examination, Examiner is assuming the aforementioned claim clause should be replaced with –the bottom portion of the first implant component--. Claim(s) 7-9, which depend from claim 6, inherit all the problems associated with claim 6. Claim 18 recites the limitation "the first implant component" in line 7. There is insufficient antecedent basis for this limitation in the claim. Claim(s) 19, 21, which depend from claim 18, inherit all the problems associated with claim 18. Claim 18 recites the limitation "the second implant component" in lines 14-15. There is insufficient antecedent basis for this limitation in the claim. Within claim 18, lines 16-17: Applicant claims, “the first component and the second component are each configured to couple with at least a portion of a talus and a calcaneum of a patient”; it is unclear, and therefore indefinite, if the talus and the calcaneum (from the aforementioned claim requirement) are redefining the first and second bones (from claim 18, liens 34 and 10-11) OR in addition to the first and second bones (from claim 18, liens 34 and 10-11). Claim 12 depends from cancelled claim 10. For the purposes of examination Examiner is assuming claim 12 should depend from claim 1. Claim(s) 13, which depend from claim 12, inherit all problems associated with claim 12. Claim 14 depends from cancelled claim 10. For the purposes of examination Examiner is assuming claim 14 should depend from claim 1. Claim(s) 115-17, which depend from claim 14, inherit all problems associated with claim 14. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1, 4-9, 12-21 is/are rejected under 35 U.S.C. 102(a)(1) and 35 U.S.C. 102(a)(2) as being anticipated by Perier et al. (US 2020/0078064 A1). With respect to claim 1.
