Office Action

§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 . Status of Claims Claims 1, 13, and 14 are currently amended, Claims 2-4 and 6 are as originally filed, Claim 5 is canceled, and Claims 7-12 are as previously presented. Claim Interpretation Claim 14 recites “high saturation magnetic flux density” in lines 1 and 2. The limitation “high” is interpreted as being equal to or more than 2.2 Tesla based on the original specification at [0021] and [0024]. 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 14 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. The term “high torque” in claim 14 is a relative term which renders the claim indefinite. The term “high” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. The specification as originally filed does not provide support for what is considered “high torque.” Correction is required, though new matter will be subject to analysis under 35 U.S.C. 112, first paragraph. Allowable Subject Matter Claims 1-4 and 6-13 are allowed. Claim 14 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: the reasons for indication of allowable subject matter for Claims 1-4, 13, and 14 were set forth in the office action mailed 01/26/2026. The reasons for indication of allowable subject matter for Claims 7-12 were set forth in the office action mailed 12/16/2025. Response to Arguments Applicant’s arguments with respect to Claim 14 have been considered but are moot because of the new ground of rejection under 35 U.S.C. 112(b). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
