§102 §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 . Response to Arguments Applicant’s argument on Page 6 regarding the objection to the specification has been fully considered. The objection to the specification is withdrawn in view of the amendments. Applicant’s argument on Page 6 regarding the objection to Claim 23 has been fully considered. The objection to Claim 23 is withdrawn in view of the amendments. Applicant’s argument on Pages 6-7 regarding the rejection of Claims 2-3 under 35 U.S.C. 112(b) has been fully considered. The rejection of Claims 2-3 under 35 U.S.C. 112(b) is withdrawn in view of the amendments. Applicant’s argument on Page 9 regarding the rejection of Claims 1 and 8 under 35 U.S.C. 103 over Romo in view of Vidlund has been fully considered but is not persuasive under new grounds of rejection as below. Regarding the rejection of all remaining corresponding claims, applicant’s argument submitted on Page 9 relies on the supposed deficiencies with respect to the rejection of parent Claim 1. Applicant’s argument is moot for the same reasons detailed above. While differences between the prior art and the instant application are appreciated, they are not embodied in the claims in such a way as to differentiate. 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.

Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 25 is rejected under 35 U.S.C. 103 as being unpatentable over Fung et al. (US 20180085130) in view of Caswell et al. (US 20200359997). Regarding Claim 25, Fung teaches all limitations of Claim 1, as discussed above. However, Fung does not explicitly teach wherein a cross-sectional shape of the guide catheter is elliptical. In an analogous transesophageal echocardiography field of endeavor, Caswell teaches a probe guide device for facilitating passage across an anatomical boundary, ([0055] “the ultrasound device 110 is a TEE probe. In some embodiments, the ultrasound device is a catheter, a guide catheter, or a guide wire.”), wherein a cross-sectional shape of the guide catheter is elliptical ([0055] “All or a portion of the flexible elongate member 137 may have any suitable geometric cross-sectional profile (e.g., […] elliptical, etc.)”). It would have been obvious to one of ordinary skill in the art at the time of applicant’s filing to modify with the teachings of Fung with the shape of Caswell because the modification allows for easier insertion into the patient and across the boundary, minimizing trauma or damage, when compared less-rounded cross-sections. Conclusion THIS ACTION IS MADE FINAL. 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.
