Office Action

§103
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 . Claims Claims 1-20 are pending. Claim 1 is amended. Response to Arguments Applicant’s arguments, see pages 6-9 of response filed 07/14/2026, with respect to the rejections of claims 1-7 and 1-20 under 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new grounds of rejection is made in view of Kinoshita et al 20190277880 in view of Franke et al US6233816. 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 1-7 and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Kinoshita et al 20190277880 (hereinafter “Kinoshita”) in view of Franke et al US6233816 (hereinafter “Franke”). Regarding claim 1, Kinoshita discloses an inertial sensor module (IMU-100) comprising: a first inertial sensor that detects a physical quantity of a first axis; a second inertial sensor that detects the physical quantity of the first axis (Sensors-17 and 18 are first and second inertial sensors that detect a physical quantity of a first axis, Paragraphs 0120-0125); and a flat substrate (circuit board-9) in which a first region and a second region have co-planar mounting surfaces (See Fig 13).

(Paragraphs 00235, 0238, 0243 See Figs 28-33) Allowable Subject Matter Claims 8-16 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Prior arts made available do not teach or fairly suggest, a third region surrounding the first region between the first region and the second region, a first plurality of slits provided between the first region and the third region to surround the first region, and a second plurality of slits provided between the third region and the second region to surround the third region as recited in claim 8, or the substrate includes a first plurality of support portions provided between the first plurality of slits, and the first plurality of support portions overlap any of the second plurality of slits when viewed from a center of the first region as recited in claim 12, or the substrate includes a second plurality of support portions provided between the second plurality of slits, and the first plurality of support portions do not overlap any of the second plurality of support portions when viewed from the center of the first region as recited in claim 13. The instant application provides the advantage of reducing the effects of stress and heat transferring by the alignment of the multiple frames. Conclusion The prior art as cited on the PTO-892 is made of record and not relied upon but considered pertinent to applicant's disclosure. Amano et al US20230048524 discloses a sensor apparatus according to an embodiment of the present technology includes a substrate, one or more first IMU sensors, and one or more second IMU sensors. The substrate has a first surface and a second surface opposite to the first surface. The one or more first IMU sensors are arranged on the first surface. The one or more second IMU sensors are arranged on the second surface. By arranging the IMU sensors on both the first surface and the second surface, it is possible to reduce the size the apparatus and to suppress a deformation of the substrate due to heat. This makes it possible to realize a highly accurate measurement based on a detection result (sensing result) of a plurality of IMU sensors. (Fig 1-42, Paragraphs 0095-0609) Yost US8498827 discloses a method includes combining readings from a plurality of inertial sensors to produce an estimate of the value of an inertial quantity in a manner that is fault-tolerant, more accurate than traditional sensor arrangements, and able to handle non-linear and non-Gaussian systems. Embodiments of a method also include utilizing a Monte Carlo estimation-based inference system to adaptively combine the inertial sensor outputs into a fault-tolerant highly-accurate inertial quantity estimate, an axis-reversed-paired physical arrangement of inertial sensors to minimize effects of environmental and process noise, and cross-associating sensors to ensure good sensor associations and reduce the effects of sample impoverishment. (Fig 1-7, Col 4 line 19-Col 18 line 12) Applicant's amendment necessitated the new ground(s) of rejection presented in this Office Action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
