Office Action

§102 §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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 04/12/2024 is/are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement are being considered by the examiner. Claim Objections Claim 1 is objected to because of the following informalities: Claim 1 recites “the plurality of insulating elements are configured to connect the input gear connection portion” in lines 5-6. Applicant is advised to correct to connector portions as previously introduced to remain consistent with claim disclosures. Appropriate correction is required. Claim 9 recites “the plurality of insulating elements are spaced equidistantly about an axis of the coupler” in lines 1-2. Applicant is advised to correct to the electric isolation coupler as previously introduced to remain consistent with claim disclosures. Appropriate correction is required. Claim 10 recites “a plurality of insulating elements, wherein the plurality of insulating components” in lines 6-7. Applicant is advised to correct to the plurality of insulating elements as previously introduced to remain consistent with claim disclosures. 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. Claim 19 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 recites the limitation "the plurality of insulating elements are located about an axis in reference to the first component" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim as there were no previously introduced first components. Examiner will interpret the term as referring to the input gear. Appropriate correction is required. 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Bager (US 20190360467 A1). Claim 1 Bager teaches: An electric isolation coupler (1), the electric isolation coupler (1) comprising: an input gear (3), the input gear (3) comprising an input gear connection portion (tip of input gear 3 comprising grooves 4); a rotor (2), the rotor (2) comprising a rotor connector portion (8); and a plurality of insulating elements (9) positioned between the input gear connection portion (tip of input gear 3 comprising grooves 4) and the rotor connector portion (8), wherein the plurality of insulating elements (9) are configured to connect the input gear connection portion (tip of input gear 3 comprising grooves 4) to the rotor connector portion (8); wherein the input gear (3) and the rotor (2) are electronically isolated.

Claim 5/1 Bager teaches: The electric isolation coupler (1) of claim 1 further comprising a retainer (6) attached to the input gear (3) connecting portion, wherein the retainer (6) is configured to retain the plurality of insulating elements (9) to the input gear connection portion (tip of input gear 3 comprising grooves 4). Claim 6/1 Bager teaches: The electric isolation coupler (1) of claim 1, further comprising a non-conductive spacer (6) attached to the input gear connection portion (tip of input gear 3 comprising grooves 4), wherein the non-conductive spacer (6) is attached between the plurality of the insulating elements (9) and an end of the input gear connection portion (tip of input gear 3 comprising grooves 4) and is configured for bearing axial load presented to and/or by the coupler (2 presents axial load on 9 which induces axial load on 6 which in turn induces axial load on 3). Claim 7/1 Bager teaches: The electric isolation coupler (1) of claim 1, wherein at least one of the input gear connection portion (tip of input gear 3 comprising grooves 4) or the rotor connector portion (8) encompasses the other. Claim 8/1 Bager teaches: The electric isolation coupler (1) of claim 1, wherein the rotor (2) further comprises a stopping element (axial resting platform for insulating elements 9 located at bottom of groove 4), wherein the stopping element is configured to bear an axial load on the plurality of insulating elements (9). Claim 9/1 Bager teaches: The electric isolation coupler (1) of claim 1, wherein the plurality of insulating elements (9) are spaced equidistantly about an axis of the coupler.
