§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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 03/18/2026 has been entered. Status of Claims Claims 1, 2, 4-6, 8, 9, 11-22 are pending and examined below. Response to Arguments The remarks of 03/18/2026 have been fully considered but they are not persuasive. Applicant argues that the prior art doesn't explicitly teach or disclose all of the elements of amended claim 1, in particular the following claim elements a base body configured to approximate a shape of a natural limb and form a cavity for at least partially receiving and covering a prosthetic component, wherein the base body at least partially blocks the view of the prosthesis a connection part fastened to the base body with a form fit or substance fit within an opening in the base body and configured to function as part of the base body, said connection part having an inner side facing the prosthetic component and an outer side facing away from the prosthetic component an electrical conductor for connecting the at least one first electrical connection element and the at least one second electrical connection element, wherein the electrical conductor is arranged in the connection part and permits the at least one first electrical connection element on the inner side of the base body to interact with the at least one second electrical connection element on the outer side of the base body Regarding the first bullet point – Applicant argues that Bomkamp doesn't disclose this claim language. However, Bomkamp is not relied upon to teach the base body. Nasdal discloses a base body 1 that meets of all these limitations as described in detail below. Regarding the second bullet point - Applicant argues that Bomkamp disclose this claim language. However, Bomkamp is not relied upon to teach a connection part. Nasdal discloses a connection part 185 as described in detail below. Regarding the third bullet point – Fig. 36 of Bomkamp discloses electronic cables or wires 55, as first described in paragraph 0034. This connects the battery to 417 and external electrical charging apparatus connecting them and allowing them to interact. It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention to modify the connection part of Nasdal with at least one first electrical connection element, at least a second electrical element, and an electrical conductor, as taught by Bomkamp, in order to further protect the prosthetic component from issues like abrasion, dust, and dirt while still allowing access to the electronics.
