Office Action

§102 §112
DETAILED ACTION 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 1-20 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 1 recites “a movable portion used for connecting an optical element” without reciting what the optical element is connected to. Alternatively the claim language may mean that the movable portion is connected to an optical element. For examination purposes, either interpretation may be used. 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. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Go (U.S. Publication No. 20250116877). Go teaches an optical element driving mechanism, comprising: a movable portion 120 used for connecting an optical element 110; a fixed portion 140, wherein the movable portion is movable relative to the fixed portion; and a driving assembly (M1, C1) used for driving the movable portion to move relative to the fixed portion (see paragraph 58). Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jeong (U.S. Publication No. 20180231793). Jeong teaches an optical element driving mechanism, comprising: a movable portion 1150 used for connecting an optical element 1110; a fixed portion 1010, wherein the movable portion is movable relative to the fixed portion; and a driving assembly 1170 used for driving the movable portion to move relative to the fixed portion (see paragraph 82). Regarding claim 2, a first sensing assembly 1171c, wherein: the first sensing assembly is used for detecting rotation of the movable portion relative to the fixed portion taking a first rotational axis A1 as an axis of rotation; the first sensing assembly comprises a first reference object 1171a and a first sensing element 1171c; the first sensing element corresponds to the first reference object; the first reference object comprises a first magnetic portion and a second magnetic portion arranged along a first axis (inherent to magnet). Allowable Subject Matter Claims 3-20 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include 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. Wang (U.S. Publication No. 20190230262) teaches an optical element driving mechanism, comprising: a movable portion which rotates an optical element about two axes.
