Office Action

§112
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 . 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. Response to Amendment This Action is responsive to the Reply filed on 23 January 2026 (“Reply”). As directed in the Reply: Claims 1 and 12 have been amended; no claims have been and/or remain cancelled; and no claims have been added. Thus, Claims 1-20 are presently pending in this application. Applicant’s amendment to the Specification and Claim 1 are sufficient to overcome the objections from the previous Action and are therefore withdrawn. Response to Arguments Applicant’s arguments with respect to Claims 1-20 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. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The first seven (7) paragraphs of Claim 1, and first eight (8) paragraphs of Claim 12, require, among other things, that the pull wire extend proximally out of the elongate catheter body; however, the limitations newly added to Claims 1 and 12 require that the pull wire’s entire length be within the catheter itself, until it reaches the control member, so that its perimeter can be constrained, which directly contradicts the requirement that the pullwire exit the proximal end of the catheter and extend through the proximal fixation member, which is a distinct structural feature. The originally filed application described a device which did not include this physically impossible configuration. Because the claim therefore recites a physical impossibility, there is no evidence in the record that the inventors had, as of the effective filing date of the application, possession of the entire combination of features recited in Claims 1 and 12, because it is not possible to have possession of a device which includes a physical impossibility. Claims 2-11 and 13-20 depend from one of Claims 1 and 12, inherit but do not cure this deficiency, and are therefore also rejected on the same grounds. Conclusion 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.
