Office Action

§112
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 05/02/2023 is being considered by the examiner. 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 11-23 are 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 “substantially” in claims 11, 18-19, and 22-23 is a relative term which renders the claim indefinite. The term “substantially” 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 term “substantially” can be interpreted as an completely open path or a completely closed path, for this reason the examiner recommends removing this term. Allowable Subject Matter Claims 11-23 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. Regarding independent claims 11 and 22, the prior art such as US 20180036836 A1 – Nakamura does teach welding methods for flat wires on a stator with multiple paths, but is completely silent on the specific method of over lapping paths. Specifically, after applying the laser beam in the first substantially closed path, performing, in either order:(a) applying the laser beam in a second substantially closed path within the second end surface to form a second molten pool; and (b) applying the laser beam in at least one of (1) a path starting at the first molten pool and extending to the second end surface, and (2) a third substantially closed path extending over the first end surface and the second end surface; wherein: the first and second molten pools are connected by the at least one of (1) the path starting at the first molten pool to the second end surface, and (2) the third substantially closed path extending over the first end surface and the second end surface in claim 11 and (a) applying the laser beam in a second substantially closed path within the second end surface to form a second molten pool; and (b) applying the laser beam in at least one of (1) a path starting at the first molten pool and extending to the second end surface, and (2) a third substantially closed path extending over the first end surface and the second end surface; wherein: the first and second molten pools are connected by the at least one of (1) the path starting at the first molten pool to the second end surface, and (2) the third substantially closed path extending over the first end surface and the second end surface in claim 22.
