Office Action

§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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2/27/2026 has been entered. Response to Amendment Acknowledgment is made to the amendment received 2/27/2026. Response to Arguments Applicant’s arguments with respect to claim 1 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. Previously, claim 1 was rejected under 35 U.S.C. 103 as being unpatentable over Shin in view of Bruszewski. Now, based on amendments to the claim language, claim 1 is now rejected under 35 U.S.C. 103 as being unpatentable over Shin in view of Bruszewski and Kolehmainen. Claim Rejections - 35 USC § 103 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 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 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-2, 5-6, and 8-17 are rejected under 35 U.S.C. 103 as being unpatentable over Shin et al., US 20190059994, herein referred to as “Shin”, in view of Bruszewski et al., US 20090234348, herein referred to as “Bruszewski”, further in view of Kolehmainen et al., US 5997487, herein referred to as “Kolehmainen”.

Shin does not explicitly disclose a thermopuncture stent implantation device wherein the conductive part is provided at a radial center of an entire length of the insulating middle tube, the conductive part is a hollow metal conductive tube; the conductive part is configured to implement liquid injection, and liquid passes through a tube cavity of the conductive part to reach the conductive head; or a device wherein the terminal of the proximal end of the conductive part is directly connected with a Luer connector to implement liquid injection.
