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 . Claim Rejections - 35 USC § 103 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. Claim(s) 1, 8 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Bae (WO 2022119034). Regarding claims 1, 8 and 15, teaches a horizontally flat surface; a first set of plurality of weight sensors (24, 25) positioned on the horizontally flat surface in the first section; at least one processor 100 configured to execute instructions stored in at least one memory to perform operations comprising: upon a vehicle stopping in the first section with each wheel of a plurality of wheels (FW, RW) of the vehicle on a weight sensor of the first set of plurality of weight sensors (24, 25), determining a total mass of the vehicle based on sensor data corresponding to each weight sensor of the first set of plurality of weight sensors (see para. 0090, ‘Thereafter, as the front wheel FW of the vehicle advances toward the rear end of the wheel guiders 20 and 30, it is mounted on a plurality of front sensors 24; a1, a2, a3, a4, and at the same time the rear wheel RW of the vehicle It is mounted on the rear sensor 25 (b1, b2, b3, b4) to detect the weight of the vehicle’); and determining a first coordinates of a center of gravity of the vehicle along a longitudinal axis and a lateral axis based on a weight measured at each weight sensor of the first set of plurality of weight sensors and coordinates of each weight sensor of the first set of plurality of weight sensors measured with respect to a front axle of the vehicle (see para. 0091, ‘The weight signal detected by the aforementioned front sensors and rear sensors 24 and 25 calculates the vehicle's center of gravity depending on a preset algorithm built into the controller 100, and when it is determined that the vehicle's center of gravity is within a preset range, center of gravity information, for example, information related to the safety of the center of gravity is displayed on the alarm 90 and the monitor 110’). However, Bae does not explicitly teach a driving path with a first set of plurality of weight sensors positioned on the horizontally flat surface of the driving path in the first section. However, It is known through the disclosure of Bae that the platform 40 is embedded in the ground and possibly lifted after the car is driven in an appropriate path onto the platform 40 (see para. 0088, ‘Referring to FIG. 3, in the vehicle lift device according to the present invention, the front wheel FW of the vehicle approaches the front end of the wheel guiders 20 and 30, and then rides on the upper part of the platform 40 and enters the vehicle will form a path’). Claim(s) 7 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Bae in view of Hirata et al. (JP 2007256244, hereafter referred to as Hirata). Bae does not explicitly teach wherein the at least one processor is further configured to perform the operations comprising transmitting, to a computing device of the vehicle, the determined total mass of the vehicle and the coordinates of the center of gravity of the vehicle along the longitudinal axis and the lateral axis. Hirata teaches a similar system wherein the at least one processor 10 is further configured to perform the operations comprising transmitting, to a computing device 14 of the vehicle. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the device of Bae with the teaching of Hirata since the examiner takes Office Notice of the equivalence of the mobile phone of or in the truck 2 and computing device of the vehicle for their use in the art and the selection of any of these known equivalents to transmit data to an end user would be within the level of ordinary skill in the art. Allowable Subject Matter Claims 2-6, 9-13 and 16-20 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. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to JAMEL E WILLIAMS whose telephone number is (571)270-7027.
