Claim Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 6-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hu et al. (U.S. 2020/0209439). Regarding claim 6, Hu discloses an optical element driving mechanism with all the limitations above but does not expressly disclose a position sensing assembly that senses a movement of the movable portion relative to the fixed portion, the position sensing assembly comprising: a first reference element; a first sensing element, corresponding to the first reference element; and a balance element, wherein: the first reference element is a first magnetic element; the balancing element is a second magnetic element. However, Hu discloses an embodiment of the invention comprising a position sensing assembly (9-SA, Fig. 92; page 27, para [0386]) that senses a movement of a movable portion (9-MA, Fig. 92; page 27, para [0386]) relative to a fixed portion (9-FA, Fig. 92; page 27, para [0386]), the position sensing assembly (9-SA, Fig. 92) comprises: a first reference element (upper 9-RGE, Fig. 92; page 27, para [0390]); a first sensing element (9SE, Fig. 93; page 27, para [0390]), corresponding to the first reference element (upper 9-RGE, Fig. 93); and a balancing element (bottom 9-RGE, Fig. 93; page 27, para [0390]), wherein: the first reference element is a first magnetic element (upper 9-RGE is a first magnetic element, Figs. 93-94; page 27, para [0390]); the balancing element is a second magnetic element (bottom 9-RGE is a second magnetic element, Figs. 93-94; page 27, para [0390]) in order to sense the position and movement of the movable assembly relative to the fixed assembly (page 27, para [0386]). Therefore, before the time of the effective filing of the claimed invention, it would have been obvious to one of ordinary skill in the art to provide the optical element driving mechanism (2-100, Fig. 17) of Hu with the position sensing assembly (9-SA, Fig. 92; page 27, para [0386]) that senses a movement of the movable portion (2-MA, Fig. 17; 9-MA, Fig. 92; page 27, para [0386]) relative to the fixed portion (2-FA, Fig. 17; 9-FA, Fig. 92; page 27, para [0386]), wherein the position sensing assembly (9-SA, Fig. 92) comprises: a first reference element (upper 9-RGE, Fig. 92; page 27, para [0390]); a first sensing element (9SE, Fig. 93; page 27, para [0390]), corresponding to the first reference element (upper 9-RGE, Fig. 93); and a balancing element (bottom 9-RGE, Fig. 93; page 27, para [0390]), wherein: the first reference element is a first magnetic element (upper 9-RGE is a first magnetic element, Figs. 93-94; page 27, para [0390]); the balancing element is a second magnetic element (bottom 9-RGE is a second magnetic element, Figs. 93-94; page 27, para [0390]) in order to obtain the benefits of sensing the position and movement of the movable assembly relative to the fixed assembly as taught by Hu (Figs. 92-94; page 27, para [0386]). Regarding claim 7, Hu discloses an optical element driving mechanism with all the limitations of claim 6 above and further discloses wherein a volume of the first magnetic element (such as volume of upper 9-RGE, Fig. 94) is larger than a volume of the second magnetic element (such as volume of portion S of bottom 9-RGE, Fig. 94). Allowable Subject Matter Claims 8-20 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: the prior art as presently searched does not disclose the optical element driving mechanism of claim 8 (having all the combination of features including wherein: when viewed along the main axis, the first magnetic element is located at the third corner; when viewed along the main axis, the second magnetic element is located at the first corner) and does not disclose the optical element driving mechanism of claim 12 (having all the combination of features including the circuit assembly comprises: a first circuit element, electrically connected to the first lead-out portion; a second circuit element, electrically connected to the fourth lead-out portion; and a third circuit element, wherein the second lead-out portion is electrically connected to the third lead-out portion through the third circuit element, wherein: when viewed along the main axis, the first circuit element is located at a first side portion of the optical element driving mechanism; when viewed along the main axis, the second circuit element is located at a third side portion of the optical element driving mechanism; when viewed along the main axis, the third circuit element is at least partially located at the first side portion). Claims 9-11 are objected to as being dependent on claim 6. Claims 13-20 are objected to as being dependent on claim 12.
