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 . Status of Claims The rejections of claims 1, 2, 4-10, 13, 14, 15, and 17, 18, and 20 under 35 U.S.C. 103 have been withdrawn in light of the Applicants’ arguments. Claims 1, 2, 13, 14, 15, 18, and 20 have been amended and claims 3, 11, 12, 16, and 19 have been cancelled. Thus, claims 1, 2, 4-10, 13, 14, 15, and 17, 18, and 20 are presented for examination. 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 factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1, 2, 8, 9, 10, 13, 14, 15, and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kato et al. [Japanese Patent Application 2012-145989] in view of Uchida [Japanese Patent Application 2019-159458], and in further view of Wolterman [U.S. Patent Publication 2006/0181433] With regard to claim 1, Kato et al. meets the limitation of: a traffic monitoring device comprising a memory [alternate-traffic signal devices having a processing device that operates by program control (paragraph 0011) where one with ordinary skill in the art would deduce the program used to control the processor is stored upon a memory device] measuring speed of the vehicle [a speed detection sensor used for detecting a speed of a vehicle (paragraph 0012)] setting a traffic light facing the vehicle to a light color indicating permission to go forward in a case where the speed of the vehicle is within a prescribed range [the display of a green lamp to signal a vehicle operator to proceed through an intersection (paragraph 0020)] in a case where the speed of the vehicle exceeds a limit value, setting the traffic light facing the vehicle to a light color indicating prohibition to go forward [a speed sensor determining if a vehicle’s speed is equal to or higher than a predetermined speed (paragraph 0022) and a light changing to blue to signal the vehicle to be on standby when the speed of the vehicle has been detected (paragraph 0007)] However, Kato et al. fails to disclose of configured to store instructions to perform acquiring time-series image data showing a vehicle.

In the field of traffic management systems, Toyama teaches: reporting a violation of traffic law by the vehicle to police [a vehicle's driving status and license plate will be recorded and reported to the police box, police station or police car (paragraph 0011)] It would be obvious to one with ordinary skill in art before the effective filing date to combine the elements of Kato et al., Uchida, Wolterman, and Toyama to create a traffic monitoring device where the device determines the speed of a vehicle from the sequentially captured pictures taken of the vehicle when it passes through an intersection and reported to the police when the vehicle is traveling through the intersection when it does not have the right of way in order to enforce traffic rules wherein the motivation to combine is to create a system for regulating traffic (Kato et al., paragraph 0001). With regard to claim 5, Kato et al. meets the limitation of: an excess of a speed limit by the vehicle [a speed sensor determining if a vehicle’s speed is equal to or higher than a predetermined speed (paragraph 0022)] However, the combination of Kato et al., Uchida, and Wolterman fails to disclose of reporting to the police.
