Office Action

§102 §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 . 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. Claim Objections Claim 1 objected to because of the following informalities: “and comprising” in line 4 should be written “comprising” Appropriate correction is required. Claim 4 objected to because of the following informalities: “plurality pairs” in line 1 should be written “plurality of pairs” Appropriate correction is required. Claim 20 objected to because of the following informalities: “The end effector of any claim 1” in line 1 should be written “The end effector of claim 1” Appropriate correction is required. 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. Claims 1-20 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 1 recites the limitation “pulse filed ablation” in line 6. It is unclear whether this limitation should be interpreted as “pulse field ablation” or some other interpretation. Claims 2-10 are rejected as being dependent upon a rejected base claim. Claim 11 recites the limitation “pulse filed ablation” in line 3. It is unclear whether this limitation should be interpreted as “pulse field ablation” or some other interpretation. Claims 12-20 are rejected as being dependent upon a rejected base claim. 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(s) 1-14, 16, and 19-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ebrahimi et al., (US 20230200895; hereinafter Ebrahimi).

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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 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. Claim(s) 15 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ebrahimi, as applied to claims 1 and 14 above, and further in view of Toth et al., (US 20160351292; hereinafter Toth). Regarding claim 15, Ebrahimi discloses the end effector of claim 14, but fails to disclose the planar high dielectric layer comprising ceramic doped polymer. However, Toth (Figure 1) teaches a medical probe (100), ([0046]), wherein a dielectric material used for insulation may comprise a ceramic doped polymer ([0092]: ceramic loaded polymer). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Ebrahimi to include the planar high dielectric layer comprising ceramic doped polymer, as taught by Toth, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. MPEP 2144.07. Regarding claim 17, Ebrahimi (Figures 1-6) further discloses the planar body (flat body of element 400) comprising a plurality of longitudinally extending plates (446) being angled (in a serpentine shape) such that the plurality of longitudinally extending plates (446) are configured to overlap, longitudinal side on longitudinal side, upon retraction of the end effector (400) into a sheath (124), ([0055]-[0060], [0066]). Ebrahimi fails to disclose that the plurality of longitudinally extending plates are ceramic. However, Toth (Figure 1) teaches a medical probe (100), ([0046]), wherein a base dielectric material used for insulation may comprise a ceramic ([0092]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Ebrahimi to include the plurality of longitudinally extending plates being ceramic, as taught by Toth, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. MPEP 2144.07. Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ebrahimi, as applied to claim 1 above, and further in view of Maor, (US 20160113709). Regarding claim 18, Ebrahimi (Figures 1-6) further discloses the end effector (400) being configured to provide pulse field ablation electrical pulses between pairs of ablation electrodes (pairs of electrodes A-D shown in annotated Figure 6 above) of the plurality of ablation electrodes (A-D), ([0067]), but fails to teach the pulses having a voltage of about 600 volts and about 1,200 volts. However, Maor teaches an end effector for a medical probe configured to provide pulse field ablation electrical pulses having a voltage of about 600 volts ([0221]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Ebrahimi to include the electrical pulses having a voltage of about 600 volts and about 1,200 volts, as taught by Maor, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art.
