§102 §103
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 . Status of Claims Claims 30, 33-43, and 46-60 are pending and examined below Response to Arguments The remarks of 09/23/2025 have been fully considered but they are not persuasive. Applicant argues that the prior art of record doesn't explicitly teach or disclose all of the elements of amended claims 30 and 41, in particular the following claim language: “a central portion, wherein the male interface of the first coupling portion includes a shaft extending arcuately around the central portion in a first angular range, and wherein the second coupling portion extends around the central portion in a second angular range and the female interface of the second coupling portion includes a receptacle” However, upon reconsideration of Figs. 1 and 2, link 10 discloses a central region 12 as well as shafts extending arcuately around at least the first, second, and third coupling regions as indicated in the rejections of claims 30 and 41. Therefore, claims 30 and 41 remain rejected under 35 U.S.C 102(a)(2) as being anticipated by US 2016/0101371 A1 (Gruenwald) Claim Rejections - 35 USC § 102 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) 30, 37, 41-43, 46, 47, 53 and 59 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US 2016/0101371 A1 (Gruenewald) Regarding claim 30, Gruenewald discloses a link for a prosthesis system (Fig. 2, wherein element 10 is configured for this intended use), the link comprising: a first coupling portion (see annotated Fig. 2 below) including a male interface (Fig. 2, 161) for engaging a female interface (Fig. 2, 160) of another link (see Fig. 4, wherein 161 of one link engages with 160 of another link) a second coupling portion (9, Fig. 6) including a female interface for engaging a male interface of another link (see Fig. 4, wherein 160 of one link engages with 161 of another link); and a central portion (see annotated Fig. 2), wherein the male interface of the first coupling portion includes a shaft extending arcuately around the central portion in a first angular range (see annotated Fig. 2, wherein shaft extends arcuately around the central portion), and wherein the second coupling portion extends around the central portion in a second angular range (see annotated Fig. 2, wherein second coupling portion extends around central portion) and the female interface of the second coupling portion includes a receptacle (see annotated Fig. 2, “receptacle”) PNG media_image1.png 742 894 media_image1.png Greyscale Regarding claim 37, Gruenewald further a beam (Fig. 2, 13) extending radially outwardly from the central portion (Fig. 1, wherein 13 extends radially outwardly from 12).
