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 . Election/Restrictions Applicant’s election without traverse of Species II in the reply filed on 10/03/2025 is acknowledged. Claims 2-4 and 18-19 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Species I and III-IV, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 10/03/2025. 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 5-17 and 20 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. Claim 5 recites “the side connecting portions” is indefinite and unclear since claim 1 recites “a plurality of side connecting portions”. Claim 5 recites “the side connecting portions each are further configured to couple the middle first coil and the outermost second coil” is indefinite and unclear because the claim limitation appears to have the middle first coil coupled to the outermost second coil. However, the middle first coil appears to be separate from the outermost second coil. The examiner suggests clarification. Claim 5 recites the limitation "the middle first coil" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 5 recites the limitation "the outermost second coil" in lines 2-3. There is insufficient antecedent basis for this limitation in the claim. Claim 6 recites “the side connecting portions” is indefinite and unclear since claim 1 recites “a plurality of side connecting portions”. Claim 7 recites the limitation "the outermost first coil" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation "the innermost first coil" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation "the middle first coil" in lines 3-4. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation "the outermost second coil" in line 5. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation "the innermost second coil" in line 6. There is insufficient antecedent basis for this limitation in the claim. Claim 14 recites the limitation "the outermost first coil" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 17 recites “the side connecting portions” is indefinite and unclear since claim 1 recites “a plurality of side connecting portions”. Claim 20 recites the limitation "the outermost first coil" in line 3. There is insufficient antecedent basis for this limitation in the claim. 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(s) 1, 5, 8-10, 13-17, and 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lim et al. [U.S. Pub. No. 2008/0284552].
