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 . Response to Arguments Applicant's arguments filed October 22nd, 2025 have been fully considered but they are not persuasive. Applicant argues that tabs 68 and 70 are not “positioned in one of the plurality of slots”. The Examiner respectfully disagrees with this assertion. The tabs must be within the slot for the slots to be resiliently deformed for resiliently holding the crossbar adapter as outlined in paragraph 21 of Ryall. The tabs must be within the slot as the slot is dimensioned to house the crossbar and the tabs resiliently deform as outlined above. 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. Claims 1-5, 8-14 and 21-25 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ryall et al. (US 2009/0078096). Regarding claim 1, Ryall et al. discloses an adapter for an orthopedic reamer (50, figure 3) comprising a main body (52) having a recess (see figure below) and a plurality of slots (see figure below) communicating with the recess; and at least a first spring (68/70, ¶21) coupled to the main body and positioned in one of the plurality of slots (figure 3), wherein the first spring is configured to engage a cross-member (e.g. 74, 76) of a reamer head (e.g. 72, ¶21) and force the cross-member to engage with a part of the main body that forms the one of the plurality of slots (¶21, figure 4). Regarding claim 2, Ryall et al. disclose the first spring is formed from the main body (figure 3). Regarding claim 3, Ryall et al. disclose the first spring and the main body are an integral single piece component (figure 3). Regarding claim 4, Ryall et al. disclose the at least the first spring comprises at least two springs (68, 70) that are spaced from one another and each positioned in different of the plurality of slots (figures 3-4). Regarding claim 5, Ryall et al. disclose the plurality of slots comprise four slots equidistantly spaced about a centerline (see figure below) of the adapter with each slot having a respective one of the at least the first spring (figures 3-4). Regarding claim 8, Ryall et al. disclose a coupling feature (see figure below) for connecting the adapter to one of a shaft or a robotic arm. Regarding claim 9, Ryall et al. disclose a reamer head (72) having a first cross-member (74) and a second cross-member (76), wherein the second cross-member is received in additional of the plurality of slots (figure 4). Regarding claim 10, Ryall et al. disclose the first cross-member and the second cross- member intersect within the recess (figure 4). Regarding claim 11, Ryall et al. disclose the at least the first spring is formed from the main body and is an integral single piece component with the main body (figure 3). Regarding claim 12, Ryall et al. disclose the at least the first spring comprises at least two springs 68’s and 70’s) that are spaced from one another and each positioned in different of the plurality of slots (figures 3-4).
