Office Action

§102
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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 7/28/2025 was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 102 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. . Claims 1, and 4-5 are rejected under 35 U.S.C. 102(a1) as being anticipated by Ichikawa (US 5,642,235). Regarding claim 1 Ichikawa teaches (figs. 1-5) a lens piece, comprising: a lens body (20), having a cylindrical shape and comprising a lens sidewall (21) parallel to an optical axis of the lens piece (col. 4, lines 5-19); and a single wing, configured for being gripped by a positioning apparatus in moving the lens piece, and transversely protruding from only one side of the lens sidewall of the lens body, and comprising a throughhole from top to bottom of the single wing (col. 4, lines 5-19). Regarding claim 4 Ichikawa teaches (figs. 1-5) a lens piece, where the lens body and the single wing are formed integrally (col. 1, line 48-52). Regarding claim 5 Ichikawa teaches (figs. 1-5) a lens piece, where the throughhole has a semicircle shape (see fig. 3). Allowable Subject Matter Claims 7-20 are allowed. The following is an examiner’s statement of reasons for allowance: The primary reason for allowance is the lens and lens barrel structure. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Claims 2-3, and 6 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Further lens and lens barrel systems include Normura et. al. (US 6,055,111) and Worst et. al. (US 5,192,319).
