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 . 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) 15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by White et al. (US Publication No. 2023/0013570 A1). Regarding Claim 15, White discloses a retractor (11, Fig. 12) comprising: a proximal portion (see figure below); and a distal portion (see figure below) opposite the proximal portion, the distal portion comprising: a first blade engagement (see figure below) having a blade receptacle (900) defined in a first end of a body of the first blade engagement (fig. 12), the blade receptacle having a lateral opening (940) that narrows to a seat (930) for receiving a shaped blade head (shown in Fig. 15A), the seat defining a shape that constrains translation, rotation, and angulation of the shaped blade head (fork tines 954, 956 of the seat prevent translation and angulation of head [0131] while tooth 919 of the seat prevents rotation of the head [0132]); and a second blade engagement (see figure below) having a blade receptacle (900) defined in a first end of a body of the second blade engagement, the blade receptacle having a lateral opening (940) that narrows to a seat (930) for receiving a shaped blade head (shown in Fig. 15A), the seat defining a shape that constrains translation, rotation, and/or angulation of the shaped blade head (fork tines 954, 956 of the seat prevent translation and angulation of head [0131] while tooth 919 of the seat prevents rotation of the head [0132]).

Claims 16-20 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. Response to Arguments Applicant’s arguments with respect to claim(s) 15 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
