Office Action

§103
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 . Response to Amendment The Amendment filed 04/27/2026 has been entered. Claims 12, 19, 20 and 29 were canceled and claims 36-37 are new. Claims 1-11, 13-18 and 21-28 and 30-37 are now pending in the application. 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 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 of this title, 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, 3, 11, 13, 15, 18, 28, 31, 34-35 and 37 are rejected under 35 U.S.C. 103 as being unpatentable over Chandra et al. (US 20020138582 A1 hereinafter Chandra) in view of Vitek et al. (US 20220147751 A1 hereinafter Vitek) As to independent claim 1, Chandra teaches method of identifying desired information comprising: determining a coarse filter based on a rule; [a rule has a coarse filter ¶583-584 "Each rule comprises an association with one event through a coarse-grain filter, a fine-grain filter that has one or more conditions, zero or more constants, one or more actions or handler"] coarse filtering data with the coarse filter [ ¶545, ¶573 a coarse filter to filter based on event header Fig. 17B 1712 ¶584 "coarse-grain filters carry out filtering only on a header portion of an event message."] determining a fine filter based on the rule; and [rule includes a fine filter ¶583-585 "Rule conditions may be created as coarse-grain filters or fine-grain filters"] fine filtering the course-filtered sensor data with the fine filter; [The coarse filter first selects event messages based on basic criteria in the message header. Then, the fine filter further examines these pre-selected messages in detail, applying more specific conditions that must all be met for the associated action to trigger ¶602 "If the event message matches one of the coarse-grain filters, then in block 1742, one or more rules with fine-grain filters are retrieved. Rule constants are extracted from the rules in block 1746. In block 1748, the fine-grain filters are applied to the event message"] Chandra does not specifically teach coarse filtering data received in real-time with the coarse filter, defining coarse-filtered sensor data; and wherein said coarse filtering is remote from said fine filtering. However, Vitek teaches coarse filtering data received in real-time with the coarse filter, defining coarse-filtered sensor data; and [Real time detection (filtering) of camera images ¶55 " an image may be captured using a vehicle based camera and real-time automated pedestrian avoidance may be performed based on the object detection techniques described herein.

[Separate coarse Fig. 6 600 and fine stages Fig. 6 610 ¶66 "coarse stage), heatmap network 600 outputs heatmaps (e.g., an object center heatmap and an object scale heatmap) as initial ROIs from an input image. The input image and the heatmaps are then processed by post-processing component 605. A second stage (e.g., a fine stage) determines ROIs to be passed to object detection network 610 (e.g., such that the object detection network 610 that performs fine searching computations only performs such computations on refined ROIs from post-processing component 605"] Accordingly, it would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the filtering system by Chandra by incorporating the coarse filtering data received in real-time with the coarse filter, defining coarse-filtered sensor data; and wherein said coarse filtering is remote from said fine filtering disclosed by Vitek because both techniques address the same field of detection analysis and by incorporating Vitek into Chandra saves computation costs with improved detection [Vitek ¶3].

Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Applicant is required under 37 C.F.R. § 1.111(c) to consider these references fully when responding to this action. Varadarajan et al. (US 20190007690 A1) teaches edge device camera connected to an internet-based object detector (see ¶10) 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.
