Office Action

§102
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 . Election/Restrictions Claims 2-24 and 28-34 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 3/09/2026. Applicant's election with traverse of Group 16 in the reply filed on 3/09/2026 is acknowledged. The traversal is on the ground(s) that the examiner has divided the claims into many alleged different inventions and the application only describes several different embodiments. Applicant continues, elements 110, 1120, 130 are elements that are present in most if not all of the embodiments. This is not found persuasive because the test for unity is that the inventions share a technical feature that define a contribution which each of the claimed inventions, considered as a whole, makes over the prior art. In this case Lizotte teaches the technical feature of elongated member 110, first connector 120 and second connector 130 shared by the claims and, therefore, claims lack unity. Note that this application was not filed under U.S. practices, therefore, any arguments related to U.S. restriction practices are hereby moot. The requirement is still deemed proper and is therefore made FINAL. 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. Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chege et al (WO 2018/064725, applicant provided reference). Referring to all embodiments and figures, Chege et al teaches an upper extremity prosthesis for placement on a residual limb of a person (see claims 16-17) comprising: an elongated member 4 having a first end and an opposite second end (self-evident and interchangeable); outer prosthetic shell (fairing, such as 21, 41 etc.) having a first end and an opposite second end (self-evident and interchangeable); and and at least a first support (one of 5 and 6; Fig. 4) and a second support (the other of 5 and 6), wherein the first support and the second support surround and are fixedly coupled to the elongated member 4 at first and second attachment points (see par. 00106-00107 and all figures), respectively, the outer prosthetic shell 21 surrounding and being coupled to the first support and the second support (Fig. 4). Allowable Subject Matter Claims 25-27 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. The following is an examiner’s statement of reasons for allowance: The prior art of record fails to teach the upper extremity prosthesis of claim 1 further comprising wherein an inner face of the first support includes a recessed section and the second support includes a through hole that is colinear with the recessed section. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Sevier (2018/016117): elongated member 102 with first and second supports 104.
