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 3 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.
In claim 3, Applicant recites “wherein a coil connection route from a positive lead-in terminal to a negative lead-out terminal in the first branch winding is 1a, 7b, 13a, 19b, 25a, 31b, 37a, 43b, 2c, 8d, 14c, 20d, 26c, 32d, 38c, 44d, 2e, 44e, 39e, 33e, 26e, 20e, 15e, 9e, 3d, 45c, 39d, 33c, 27d, 21c, 15d, 9c, 2b, 44a, 38b, 32a, 26b, 20a 14b, 8a; a coil connection route from a positive lead-in terminal to a negative lead-out terminal in the second branch winding is 2a, 8b, 14a, 20b, 26a, 32b, 38a, 44b, 3c, 9d, 15c, 21d, 27c, 33d, 39c, 45d, 3e, 45e, 38e, 32e, 27e, 21e, 14e, 8e, 2d, 44c, 38d, 32c, 26d, 20c, 14d, 8c, 1b, 43a, 37b, 31a, 25b, 19a, 13b, 7a.
While it appears that Applicant is attempting to recite the position of the coil in each layer, the claim does not clearly establish antecedent basis to describe such positions in the layers.
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.
