Office Action

§102
DETAILED ACTION The following is a non-final office action is response to communications received on 12/24/2025. Claims 1-18 are currently pending and addressed below. 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 Applicant's election with traverse of Species LL (Fig 45) (claims 1, 4, 5, 12-15 & 18) in the reply filed on 12/24/2025 is acknowledged. The traversal is on the ground(s) that the examiner did not identify claim 1 as a generic claim. Although claim 1 may be generic to several of the species, the identified species are proper, distinct and independent. 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(s) 1, 4, 5, 12-15 & 18 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakano et al. (US 2012/0064288). PNG media_image1.png 640 420 media_image1.png Greyscale Regarding Claim 1, Nakano teaches a method for producing a structural medical device (Fig 22A) configured for installation into a prepared cavity (i.e., femur), comprising the steps of: a) manufacturing a body including a body (shown) portion sized for a pressfit fixation into the prepared cavity; and b) disposing a framework (23) within said body portion during said manufacturing step a) wherein said framework includes a set of one or more structural elements (23) configured to produce an anisotropic (as the framework and structure are not symmetric) bulk material property in said body portion. Regarding Claims 4 & 14, Nakano teaches wherein said framework includes a first set (medial-lateral running chamber elements 23) of one or more structural elements and a second set (anterior-posterior running chamber elements 23) of one or more structural elements, each set of structural elements disposed in different non-overlapping regions of said body portion (as they run parallel with one another). Regarding Claims 5 & 15, Nakano teaches wherein said first set of structural elements is different than said second set of structural elements (Fig 22A illustrates both a different size and orientation of the identified structural elements). Regarding Claim 12, Nakano teaches wherein the prepared cavity includes a channel prepared in a long bone (i.e., femur) and wherein said body includes a stem (Fig 22A). Regarding Claim 13, Nakano teaches wherein said body portion includes a foundation layer of said stem (solidified walls 21). Regarding Claim 18, Nakano teaches wherein said step of manufacturing includes operating an additive manufacturing process [0069] configured to manufacture at least a portion of said body.
