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 . Response to Arguments Applicant’s arguments, see Remarks, filed 12/15/2025, with respect to the rejection(s) of claim(s) under 35 USC 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Lupotti (US 20160317844, previously presented) in view of 20150273246 to Darlington et al. Additional references used for dependent claims. See details below. Since this combination was not previously presented, the office action is being submitted as a non-final rejection. 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 (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. 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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 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) 22, 24, 30 and 41 is/are rejected under 35 U.S.C. 103 as being unpatentable over US Pat Pub No. 20160317844 to Lupotti in view of US Pat Pub No. 20150273246 to Darlington et al.

Regarding claim 34. (New) Lupotti as modified by Darlington renders obvious the system according to claim 22, but fails to disclose wherein the algorithm comprises a bias. Rajagopalan, from a similar field of endeavor, teaches its algorithm to comprise a bias which tends to choose a smaller functional assembly (para 0214). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Lupotti as modified by Darlington, with the teachings of Rajagopalan to provide the predictable result of allow the algorithm to tend toward a certain outcome as desired. Regarding claim 35. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 34, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214). Rajagopalan fails to explicitly disclose wherein the bias comprises a bias toward delivering the ablative energy to all of a volume of a treatment target to sufficiently ablate the perimeter of the volume. However, changing the bias from one behavior to another is understood to be obvious to try and simple substitution of one known element for another to obtain predictable result (See MPEP 2143). Furthermore, the applicant’s specification has not demonstrated any criticality for this specific limitation. Regarding claim 36. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 34, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214). Rajagopalan fails to explicitly disclose wherein the bias comprises a bias toward delivering the ablative energy to a limited volume of a treatment target to avoid delivery of energy to non-target tissue proximate the volume. However, changing the bias from one behavior to another is understood to be obvious to try and simple substitution of one known element for another to obtain predictable result (See MPEP 2143). Furthermore, the applicant’s specification has not demonstrated any criticality for this specific limitation. Regarding claim 37. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 34, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214). Rajagopalan fails to explicitly disclose wherein the bias can comprise a conservative energy delivery bias or an aggressive energy delivery bias. However, changing the bias from one behavior to another is understood to be obvious to try and simple substitution of one known element for another to obtain predictable result (See MPEP 2143). Furthermore, the applicant’s specification has not demonstrated any criticality for this specific limitation. Regarding claim 38. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 37, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214).

However, changing the bias from one behavior to another is understood to be obvious to try and simple substitution of one known element for another to obtain predictable result (See MPEP 2143). Furthermore, the applicant’s specification has not demonstrated any criticality for this specific limitation. Regarding claim 39. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 37, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214). Rajagopalan fails to explicitly disclose wherein the algorithm is configured to set the bias based on the location of the treatment target. However, changing the bias from one behavior to another is understood to be obvious to try and simple substitution of one known element for another to obtain predictable result (See MPEP 2143). Furthermore, the applicant’s specification has not demonstrated any criticality for this specific limitation. Regarding claim 40. (New) Lupotti as modified by Darlington and Rajagopalan renders obvious the system according to claim 37, Rajagopalan teaches that it is known to provide a bias in the algorithm to achieve a desired outcome (see para 0214). Rajagopalan fails to explicitly disclose wherein the algorithm is configured to set the bias based on the type of treatment provided by the system.
