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 the Claims Claims 1-23 were previously pending. Claims 1-2, 5, 15-16, 20 have been amended. No claims have been canceled, and no new claim shave been added. Thus claims 1-23 are currently pending including independent claims 1, 15, 20. Claim Rejections - 35 USC § 102 The rejections under 35 U.S.C. 103 are removed in light of the remarks and amendments filed 09/11/2026. 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. 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) 1-5, 7, 9, 11-12, 15-23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez-Serrano (herein referred to as Rodriguez) (Rodriguez-Serrano, J.A., Sandhawalia, H., Bala, R., Perronnin, F., Saunders, C. (2012). Data-Driven Vehicle Identification by Image Matching. In: Fusiello, A., Murino, V., Cucchiara, R. (eds) Computer Vision – ECCV 2012. Workshops and Demonstrations. ECCV 2012. Lecture Notes in Computer Science, vol 7584. Springer, Berlin, Heidelberg. https://doi.org/10.1007/978-3-642-33868-7_53) in view of Feng (CN 110633289 A). Regarding claim 1, Rodriguez discloses a vehicle identity recognition device ([Introduction, first paragraph] vehicle identification from images such as those included in cameras) comprising: a data input interface configured to receive a first image of a first vehicle and a second image of a second vehicle ([pg. 538, second paragraph] given an image of an unknown vehicle (i.e. first image), we propose to describe the license plate sub-image and match it against a database of annotated license images to find a near-duplicate image (i.e. second image)); and at least one processor configured to control ([Introduction, first paragraph] the system for vehicle identification from images may be implemented on devices such as mobile phones (i.e. which include processors); see also [pg. 542, 4 Experiments]): a region of interest extractor to extract a first region of interest from the first image ([pg. 537, Fig. 1] plate detection from vehicle image; see also [pg. 541, first paragraph] plate localization algorithm to yield tight plate regions) and extract a second region of interest from the second image corresponding to the first region of interest (Fig. 3-4, [pg. 540, Synthesizing an Ideal License Plate Image.] synthesizing license plate images by extracting distorted versions of an original license plate image (see also [pg. 540, Photo-Realistic Transformation.])), the first region of interest and the second region of interest being partial regions of a vehicle including a vehicle license plate area ([pg. 537, Fig. 1] plate detection from vehicle image; see also [pg. 541, first paragraph] plate localization algorithm to yield tight plate regions, wherein both the original and synthesized images are license plate images); a machine learner to perform machine learning by inputting the first region of interest as training data ([pg. 541, 3.2 Similarity Learning] the training procedure includes a step including components r and s, real plate image and simulated plate images (i.e. first ROI images)); an image matcher to determine whether the first region of interest on which the machine learning is performed matches the second region of interest ([pg. 541, 3.2 Similarity Learning] minimizing the loss makes pairs with the same identity have a higher similarity than non-matching pairs (i.e. of r (original) and s (synthesized) plate images)); a license plate identifier to identify whether a license plate of the first vehicle is identical to a license plate of the second vehicle; and a controller to recognize the second vehicle as an identical vehicle based on the first region of interest matching the second region of interest and the license plate of the first vehicle being identical to the license plate of the second vehicle ([pg. 537, first paragraph] given a plate image region, search for a near-duplicate image in an annotated database, and if a duplicate is found then the identity of the near-duplicate is transferred to the input region image (i.e. the vehicle in the input image is determined to have the identity of the vehicle in the duplicate image); see also [pg. 539, Matching.]). Rodriguez fails to disclose regions of interest including a vehicle license plate external region. Feng, in a related system from the same field of endeavor of license plate number recognition based on camera images ([0002]-[0004]), discloses regions of interest including a vehicle license plate external region ([0004] the common practice is to use cameras to photograph vehicles then identify the license plate numbers of the vehicles in the images; [0030] acquire the vehicle characteristics of the target vehicle, including the license plate number, vehicle model, brand, and body color; [0071] a deep convolutional neural network is used to identify the vehicle type, brand, and body color elements of the target vehicle and similar vehicles respectively, and the weight of each element in the vehicle features is set). It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to combine Feng with Rodriguez including regions of interest including a vehicle license plate external region, as disclosed by Feng, as part of a vehicle identity recognition device, as disclosed by Rodriguez, for the purpose of improved accuracy of recognition and vehicle identification results (See Feng: [0012], [0076], [0099]). Regarding claim 2, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the at least one processor is further configured to control: a weight applier to apply different weights to each of the vehicle license plate area for at least one of the first region of interest and the second region of interest ([pg. 541, 3.2 Similarity Learning], as in equation (2), the learning process involves applying a weight (1-k) to a sample with the same identity as the real sample and a weight (k) to a sample with a different identity (i.e. external to the license plate)). Rodriguez fails to disclose applying different weights to the vehicle license plate external region for the second region of interest. Feng, in a related system from the same field of endeavor of license plate number recognition based on camera images ([0002]-[0004]), discloses applying different weights to the vehicle license plate external region for the second region of interest ([0071] a deep convolutional neural network is used to identify the vehicle type, brand, and body color elements of the target vehicle and similar vehicles respectively, and the weight of each element in the vehicle features is set). It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to combine Feng with Rodriguez including applying different weights to the vehicle license plate external region for the second region of interest, as disclosed by Feng, as part of a vehicle identity recognition device, as disclosed by Rodriguez, for the purpose of improved accuracy of recognition and vehicle identification results (See Feng: [0012], [0076], [0099]). Regarding claim 3, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 2. Rodriguez further discloses wherein a first weight is applied to the vehicle license plate area and a second weight, higher than the first weight, is applied to the vehicle license plate external region ([pg. 541, 3.2 Similarity Learning], as in equation (2), the learning process involves applying a weight (1-k) to a sample with the same identity as the real sample and a weight (k) to a sample with a different identity (i.e. external to the license plate)). Regarding claim 4, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the at least one processor is further configured to control: an image scrambler to apply an artificial image change to at least one of the first region of interest and the second region of interest, and wherein the artificial image change comprises one or more of an image brightness change, a contrast change, a blur change, and image tampering ([pg. 540, Photo-realistic Transformation] a number of transformations and distortions are applied to produce realistic images which simulate camera capture, Fig. 3(b) illustrates some operations considered (e.g. in Fig. 3B, distortions of poor contrast, rotation, shadow, blurry, and rust are applied to versions of the license plate image)). Regarding claim 5, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the at least one processor is further configured to control: a feature point extractor to extract feature points for each of the first region of interest and the second region of interest ([pg. 538, Plate Features] for the license plate image descriptor we extract Fisher vectors (i.e. by extracting feature points form the image regions)), the machine learner to perform the machine learning based on the extracted feature points as input, and the image matcher to determine whether the regions of interest are matched based on the extracted feature points ([pg. 541, 3.2 Similarity Learning] measuring of similarity between Fisher vectors as a measure of matching between synthetic and real plate images by the learning model to determine if there is a match). Regarding claim 7, Rodriguez discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the at least one processor is further configured to control the license plate identifier to: convert a license plate included in the first region of interest and a license plate included in the second region of interest into a frontal image, and determine whether the license plate of the second vehicle matches the license plate of the first vehicle ([pg. 537, last paragraph], Fig. 1 shows a vehicle image taken at an angle wherein the plate is then detected and displayed from a front angle, the image is then matched to a synthetic second region to determine the output match). Regarding claim 9, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the at least one processor is further configured to control the image matcher to: convert the first region of interest on which the machine learning is performed and the second region of interest into images of a same angle, and determine whether the converted images match ([pg. 537, last paragraph], Fig. 1 shows a vehicle image taken at an angle wherein the plate is then detected and displayed from a front angle, the image is then matched to a synthetic second region which is at the same front angle to determine the output match). Regarding claim 11, Rodriguez in view of Feng discloses the vehicle identity recognition device of claim 1 as applied above. Rodriguez further discloses wherein the machine learning is at least one of supervised learning and unsupervised learning ([pg. 541, 3.2 Similarity Learning] supervised semantic indexing approach for similarly learning model).

Response to Arguments Applicant’s arguments filed 09/11/2026 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made under 35 U.S.C. 103 as stated above. Applicant asserts on page 12 that "Rodriguez does not disclose an ROI that comprises both a license plate area and a vehicle plate external region as required by claim 1. For at least these reasons, claim 1 is patentable over the cited art of record." Examiner agrees, and the rejection of claim 1 under 35 U.S.C. 102 is removed as stated above. However, amended claim 1 is rejected under 35 U.S.C. 103 as stated above. Applicant asserts on page 13 that "Even assuming arguendo that Rodriguez discloses the other limitations identified in the Office Action, Rodriguez fails to disclose the amended requirement that each ROI includes both a license plate area and a vehicle license plate external region. For at least these reasons, claims 2 and 3 are patentable over Rodriguez." Examiner agrees, and the rejections under 35 U.S.C. 102 are removed as stated above. However, amended claims 2-3 are rejected under 35 U.S.C. 103 as stated above. Conclusion 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.
