Office Action

§103 §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 . Response to Arguments Applicant's arguments filed 12/11/25 have been fully considered but they are not persuasive. The Applicant argues Sakamoto in view of Ben Shoshan fails to teach together with the proximal end portion of the first conductor and the proximal end portion of the second conductor, a proximal end portion of a third conductor that is connected to a third electrode provided in the catheter and configured to measure a potential in a body and is extends toward the proximal end, and wherein the second end face surrounds a third end face where the proximal end portion of the third conductor is provided as seen along the normal direction; wherein the second end face is protruded or recessed from both of the first end face and the third end face. The Examiner respectfully disagrees. Sakamoto in view of Ben Shoshan teach each and every limitation. See the Annotated Figure 3A below, from the Ben Shoshan reference. PNG media_image1.png 351 490 media_image1.png Greyscale Sakamoto discloses a single connector for multiple conductors (e.g. ¶37), 3 separate electrode areas on the catheter (e.g. ¶28) and further the use of the conductor lengths along with locations to make the creepage distance longer than the spatial distance between conductors (e.g. ¶43), but fails to explicitly state the exact orientation of the conductors. However, Ben Shoshan discloses a connector with rings of conductors at various elevations for each channel of electrodes so that a 2nd end face is protruded or recessed from the 1st and 3rd end faces as taught in Figures 1-4 and paragraphs 14-15 to allow for high power transfer of energy by maintaining the electrical contacts and corresponding channels at safe distances or pitches apart from each other, potential short circuiting from physical contact and/or creepage is avoided. It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the connector as taught by Sakamoto, with connector with rings of conductors at various elevations as taught by Ben Shoshan, since such a modification would provide the predictable results of allowing for high power transfer of energy by maintaining the electrical contacts and corresponding channels at safe distances or pitches apart from each other, potential short circuiting from physical contact and/or creepage is avoided. Therefore the rejections stand. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 5 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the 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(s) 1, 5-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sakamoto et al. (U.S. Pub. 2021/0113845 hereinafter “Sakamoto”) in view of Ben Shoshan et al. (U.S. Pub. 2023/0369815 hereinafter “Ben Shoshan”).

Regarding claim 7, meeting the limitations of claim 1 above, Sakamoto further discloses wherein the creepage distance is provided between the proximal end portion of the first terminal and the proximal end portion of the second terminal (e.g. ¶37). Regarding claim 8, meeting the limitations of claim 1 above, Sakamoto further discloses wherein the creepage distance is provided between a distal end portion of the first terminal and a distal end portion of the second terminal (e.g. ¶37). Regarding claims 9-12, meeting the limitations of claim 1 above, Sakamoto further discloses further comprising an insulator (e.g. 15) configured to cover a proximal end portion of the first conducting wire and a proximal end portion of the second conducting wire to insulate the proximal end portion of the first conducting wire and the proximal end portion of the second conducting wire from each other (e.g. Fig. 2; “15”). Regarding claim 10, meeting the limitations of claim 1 above, Sakamoto further discloses wherein the insulator includes a second insulator (e.g. 12) configured to cover the distal end portion of the second terminal connected to the proximal end portion of the second conducting wire (e.g. ¶37; “wherein the two terminal are in a single connector”), and a first insulator (e.g. 12) configured to cover, together with the second insulator, the distal end portion of the first terminal connected to the proximal end portion of the first conducting wire (e.g. ¶37; “wherein the two terminal are in a single connector”). Regarding claim 13, meeting the limitations of claim 1 above, Sakamoto further discloses wherein the catheter is a defibrillation catheter configured to apply, to an arrhythmia site, electrical stimulation based on a voltage between the first electrode and the second electrode (e.g. Abstract, ¶1).
