Office Action

§103 §112
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 . DETAILED ACTION The instant application having Application No. 18251257 filed on 05/01/2023 is presented for examination by the examiner. Examiner Notes Examiner cites particular columns and line numbers in the references as applied to the claims below for the convenience of the applicant. Although the specified citations are representative of the teachings in the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested that, in preparing responses, the applicant fully consider the references in entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the examiner. Priority As required by e M.P.E.P. 201.04, 210, 214.03, acknowledgement is made of applicant’s claim for priority based on application of National Stage entry of PCT/JP2021/035636, International Filing Date 09/28/2021 that claims priority from Provisional Application US #63109385, filed 11/04/2020. Drawings The applicant’s drawings submitted are acceptable for examination purposes. 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 3 is 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 3 recites the limitation for “a resonant portion” in line 9. However, this limitation is confusing, because it is unclear if it is the same limitation as in claim 1 for “a resonant portion” of if it represents a new and different limitation for resonant portion. Moreover, it is unclear if this limitation and further descriptions are for the same structures as in claim or if they are for some new and different structures? For the purposes of examination the above limitations and the following descriptive limitations will be treated broadly, such that they can represent the same limitation as in base claim 1, or a different limitation. It is suggested to amend the claim and provide explanations in order to remove the indefiniteness issue. 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. Claims 1-6 are rejected under 35 U.S.C. 103 as being unpatentable over Itagaki et al. (hereafter Itagaki, where English language equivalent US 20210173175 A1 is referenced) WO 2020036157 A1, in view of in view of Mizuno US 20040212794 A1. In regard to independent claim 1, Itagaki teaches (see Figs. 1-11) an optical-element driving device (lens driving device 1 of camera module A and camera mounted device e.g. OC1,2,VC on device M,V , see abstract, e.g. paragraphs [01,07-33, 47-54, 56-64, 67-80, 82-94, 132-142]), comprising: a fixing part (fixing part 20, with fixed cover 3, also AF fixing part 12, Figs. 2-5, 7-8, e.g. paragraphs [47-54,56-64, 67-80]); a movable part disposed apart from the fixing part (OIS movable part 10, AF movable 11 part disposed away from 20, Figs. 2-9, e.g. paragraphs [47-54,56-64, 67-80]); a supporting part (40, also 14,15) configured to support the movable part with respect to the fixing part (40 supports 10 with respect to 20, also as 14,15 supports 11 with respect to 12, e.g. paragraphs [56-67, 81-90], Figs. 4-5, 7-9); and a driving unit (driving part 30, 13, paragraphs [ 56,62, 68-74, 77-84, 112-113], Figs. 4-10) including an ultrasonic motor configured to convert a vibrational motion into a linear motion (i.e. as USM1,2,3, so configured, 68-74, 77-84, 112-113}68-74, 77-84, 112-113], Figs. 4-10), and a power transmission part configured to transmit a driving force of the ultrasonic motor to the movable part (power transmission part 34, 134 transmits driving force from USM2,3 or USM1 to 10, or 11, paragraphs [70-79, 92, 112-117], Figs. 4-6, 10) the driving unit being configured to move the movable part with respect to the fixing part (OIS driving 30 and AF driving unit 13 move 10, 11 with respect to 20,and/or 12, paragraphs [ 56,62, 68-74, 77-84, 112-113], Figs. 4-10), wherein: the power transmission part includes a plate making contact with a resonant portion of the ultrasonic motor (as motor contact portion plate 34b making contact with resonance part 33, (33d), also as 134b contacting 133(133d), paragraphs [77-78,119-120], Figs. 6, 10), and a material is disposed on a second surface side of the plate that is opposite a first surface of the plate that makes contact with the resonant portion (i.e. as material of 34 between coupling portions 34c opposite from sides with contacting plate portions 34b,a as depicted in Figs. 6, paragraphs [70, 74-80], and see equivalents in Figs. 10, paragraphs [116-122]). But Itagaki is silent that a damper material is disposed on the second surface side of the plate that is opposite a first surface of the plate that makes contact with the resonant portion (i.e. between portions 34c opposite from sides with contacting late portions 34b,a as depicted in Figs. 6, paragraphs [70, 74-82], and see equivalents in Figs. 10). However, Mizuno teaches in the similar field of invention of driving units/device for finely adjusting the positions and tilts of optical elements (see Figs. 1, 4, 6-7,10-12, tile, abstract, paragraphs [02, 10-11, 14-15, 19-21, 71-73, 80-82, 135-140] where the optical (1) element driver has adjusting mechanism 8 with a piezoelectric actuator 4 contacting at contacting portions and connected with elastic hinge/pilar 5, between active side of 4 and passive side of block 2 housing with optic 1, using vibration control material e.g. as gel, grease), and further teaches that a damper material is disposed on the surface side of the plate that is opposite surface of the plate that makes contact with the resonant portion (i.e. as vibration control material as e.g. as gel, grease disposed on surface(s) parts of 5 with and opposite parts of 5 from the surface contacting pzt actuator 4, as the elastic connection includes such vibration control material, which then allows for vibration control of the device, and while the vibration control material is shielded paragraphs [10-11, 14-15, 19-21, 71-73, 80-82, 135-140], e.g. Figs. Figs. 1, 4, 6-7,10-12). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to adjust and modify the power transmission part including between coupling portions and portions opposite from sides with contacting plate portions of lens driving device of Itagaki to include vibration control material as e.g. as gel, grease so that the elastic connection includes such vibration control material according to teachings of Mizuno, in order to provide vibration control of the device, and shielding of the vibration control material (see Mizuno, paragraphs [10-11, 14-15, 19-21, 71-73, 80, 135-140]).
