The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
The Amendment filed June 5th, 2026 has been entered. No claims have been amended. Claims 1-22 are pending in the application, with claim 17 withdrawn.
Response to Arguments
Applicant’s arguments with respect to claim(s) 1-16 and 18-22 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
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 10 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 10 recites the limitations "the first cam structure" and "the second cam structure" in their first appearances. There is insufficient antecedent basis for this limitation in the claim.
Examiner’s Comments
The present rejection(s) reference specific passages from cited prior art. However, Applicant is advised that the rejections are based on the entirety of each cited prior art. That is, each cited prior art reference “must be considered in its entirety”.
