Office Action

§102
DETAILED ACTION The Request for Reconsideration filed 09/16/26 has been entered. Claims 11-20 are still pending. In light of Applicant’s arguments the previous rejection of claims 11-19 have been withdrawn. However, the 102 rejection of claim 20 is maintained as detailed below. 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 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. Huawei Claim(s) 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Huawei (JP 2020-522219) (previously attached). Huawei is directed to an acceleration slip regulation method and vehicle. See Abstract. Claim 20: Huawei discloses a PID traction controller (420, ARS/TCS) for controlling a drive slip K of at least one driven wheel (440) of a single-track motor vehicle (400), comprising: a vehicle speed sensor (410) to measure a vehicle speed vFZG (Vx); a circumferential speed sensor (410) to measure a circumferential speed VAR (Vw_i) of the at least one driven wheel; and a plurality of differentiators to determine a slip acceleration αK by based on a difference of a wheel acceleration DVAR/dt (aw_i) and a vehicle acceleration dFZG/dt based on the vehicle speed sensor and the circumferential speed sensor [see Translation (“Based on the wheel slip rate and/or the wheel acceleration, the vehicle determines to enter the acceleration slip adjustment state”)], wherein the slip acceleration αK is as D-component [see Translation (“slip rate change rate”)] in the PID traction controller to control a drive slip K of the at least one driven wheel [see Translation (“the acceleration slip adjustment method includes a logical threshold control method and a PID control method…”)]. See Translation. Allowable Subject Matter Claims 11-19 are allowed. Response to Arguments Applicant’s arguments, filed 09/16/26, with respect to claim 11 have been fully considered and are persuasive. The 102 rejections of claims 11-19 have been withdrawn. Applicant's arguments with regard to claim 20, however, have been fully considered but they are not persuasive. Applicant contends that Huawei does not disclose the use of a D component of a PID traction controller. See Remarks, pages 6-7 (“the Examiner has not identified any passage in Huawei where a D-component based on slip acceleration necessarily arises”). In response, in addition to the discussion of using a PID controller throughout the Huawei specification, which necessarily includes a D-component, Huawei explicitly discusses multiple times that slip rate as well as “slip rate change rate” values are determined using a variety of parameters from the sensors, including vehicle speed, wheel speed, etc. Claim 20 broadly recites that this component is ascertained and nothing more, as compared to claim 11. It is for this reason that the claim 20 rejection is maintained, while the claim 11 rejection is withdrawn. Applicant should also consider other previously cited art, including but not limited to, US Patent Pub. No. 2018/0319384 [see para. 0064, 0083-87, 0099-104]. Conclusion THIS ACTION IS MADE FINAL. 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.
