Office Action

§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 . Election/Restrictions Applicant’s election of Group I, claims 1-15, in the reply filed on December 22, 2025 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). Claims 16-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invetnion, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on December 22, 2025. Information Disclosure Statement The information disclosure statement(s) (IDS) submitted on 12/6/2023 and 2/5/2024 has/have been acknowledged and is/are being considered by the Examiner. Drawings The Applicant is reminded to carefully review the drawing figures and the accompanying specification to ensure that all reference numerals present in the drawing figures are defined within the specification. Claim Rejections - 35 USC § 102 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 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 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 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. Claims 8, 13, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Hastings (U.S. 2009/0018599, cited above). Regarding claim 8, Hastings discloses the invention substantially as claimed, but fails to disclose that the internal battery has a rectangular shape with rounded corners. It would have been an obvious matter of design choice to a person of ordinary skill in the art to modify the device of Hastings such that the internal battery has a rectangular shape with rounded corners, because Applicant has not disclosed that the internal battery has a rectangular shape with rounded corners provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Applicant’s invention to perform equally well with the battery shape of Hastings, because it provides adequate power to the device and since it appears to be an arbitrary design consideration which fails to patentable distinguish over Hastings. Therefore, it would have been an obvious matter of design choice to modify Hastings to obtain the invention as specified in the claim. Regarding claim 13, Hastings discloses the invention substantially as claimed, but fails to disclose a fourth tail member having one or more electrodes being adapted to receive electrical signals relative to a fourth position. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Hastings to include a fourth tail member having one or more electrodes being adapted to receive electrical signals relative to a fourth position, since it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art. MPEP 2144.04 Regarding claim 14, Hastings discloses that the main body includes one or more electrodes being adapted to receive electrical signals relative to a fifth position (“FIG. 4 is a diagram of various exemplary implementations of leadless electrode assemblies 26 that may be used in the systems of FIGS. 1-3….A first leadless (or wireless) electrode assembly 26a includes a proximal electrode 121 at or near a proximal end of the assembly 26a and a distal electrode 129 at or near a distal end of the assembly 26a, according to an implementation.”, paragraph [0043]). Claims 8, 13, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Higgins (U.S. 2020/0196899, cited above). Regarding claim 8, Higgins discloses the invention substantially as claimed, but fails to disclose that the internal battery has a rectangular shape with rounded corners. It would have been an obvious matter of design choice to a person of ordinary skill in the art to modify the device of Higgins such that the internal battery has a rectangular shape with rounded corners, because Applicant has not disclosed that the internal battery has a rectangular shape with rounded corners provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Applicant’s invention to perform equally well with the battery shape of Higgins, because it provides adequate power to the device and since it appears to be an arbitrary design consideration which fails to patentable distinguish over Higgins. Therefore, it would have been an obvious matter of design choice to modify Higgins to obtain the invention as specified in the claim. Regarding claim 13, Higgins discloses the invention substantially as claimed, but fails to disclose a fourth tail member having one or more electrodes being adapted to receive electrical signals relative to a fourth position. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Higgins to include a fourth tail member having one or more electrodes being adapted to receive electrical signals relative to a fourth position, since it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art. MPEP 2144.04 Regarding claim 14, Higgins discloses that the main body includes one or more electrodes being adapted to receive electrical signals relative to a fifth position (“The housing 115 may function as a housing electrode (sometimes referred to as a can electrode)”, paragraph [0065]).
