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 . 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) 1-3 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Obana et al. (US Pub. No. 2022/0100060). Regarding claims 1-3, Obana teaches an optical system, comprising: a fixed assembly (1); a movable part (2), configured to be connected to an optical module (21), wherein the movable part is movable relative to the fixed assembly; and a driving assembly (610), configured to drive the movable part to move relative to the fixed assembly, wherein the optical system further includes a guiding assembly (30 & 50), and the movable part moves relative to the fixed assembly through the guiding assembly (para. 30); wherein the fixed assembly has an outer cover (10) and a first base (80, 95); the outer cover and the first base are arranged along a first axis; the outer cover is fixedly connected to the first base to form an accommodation space (Fig. 1); the accommodation space is configured to accommodate the movable part, the optical module and the driving assembly (Fig. 2); the optical module and the movable part are arranged along the first axis; the optical module is fixedly disposed on the movable part (Fig. 2) [claim 2]; wherein the guiding assembly includes a fixed guiding portion (50) and a movable guiding portion (30); the fixed guiding portion (50) is fixedly connected to the fixed assembly; the fixed guiding portion (50) is fixedly connected to a positioning member of the fixed assembly (the base cover 50 is fixed to the fixed assembly with screws, i.e. positioning member, para. 32); the positioning member protrudes from the first base along the first axis; the movable guiding portion is fixedly connected to the movable part; the movable guiding portion is movable relative to the fixed guiding portion; the movable part is configured to rotate with the movable guiding portion relative to the fixed guiding portion and the fixed assembly around the first axis (para. 30) [claim 3]. Allowable Subject Matter Claims 4-20 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. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 4, applicant has sufficiently defined and claimed an optical system, whereby the prior art does not teach or suggest the first power source includes a first piezoelectric element; the transfer assembly is configured to receive the first driving force and then output an external driving force; the transfer assembly has an elastic structure; the contact member is fixedly connected to the transfer assembly and configured to transmit the external driving force to the movable part; the contact member is configured to be driven by the transfer assembly to switch between a disengaged state and a contact state; in the disengaged state, the contact member is not in contact with the guiding assembly; in the contact state, the contact member is in direct contact with the guiding assembly, in combination with all other limitations set forth in the claim.
