Office Action

§102 §103
Detailed Action Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Acknowledgements 2. Applicant’s arguments/remarks, filed 07/06/2026, are acknowledged. Amended claims 1-10, 14 and newly added claims 15-20 are acknowledged. Claims 1-20 remain pending and have been examined. Response to Arguments 3. Applicant's arguments, filed 07/06/2026, with regards to independent claim 1 have been fully considered but they are not persuasive. 4. Applicant argues/remarks, on pg. 9 event signals corresponding to pixels outside the ROI are excluded from transmission; as Seo expressly states, the event signals corresponding to pixels outside the ROI “may be selectively excluded” from transmission to the processor ([0062]). Applicant further states, the selection of ROI event signals for transmission, and the corresponding exclusion of non-ROI event signals from transmission, is the express purpose of Seo. The non-ROI pixels in Seo therefore do not contribute image data to any final image; the are suppressed at the output stage. Amended claim 1 requires that the circuitry generate the final images by fusing the image data obtained via the at least two subsets of pixels during the respective specific time period. 5. The examiner, respectfully, disagree. Seo, in [0032], teaches an electronic device including an image processing device 10, vision sensor 100 and a separate vision sensor 101. As illustrated in Fig. 1, element 100 transmits event signals EVS to a processor 200; while element 101 generates and transmits signals that correspond to an external scene/object. [0036] further teaches that the processor 200 detects a movement of an object based on signals of the vision sensor 100 or based on signals generated by both vision sensors 100 and 101. [0052] teaches transmitted event signals transmitted by interface circuit 140 (Fig. 3) to detect movement of an object being imaged by the pixel array 110 of vision sensor 100. [0062] teaches that event signals EVS are generated based on events that occurred in pixel array 110 and correspondingly a virtual event map EVM is constructed. Further, the event signals are classified as either having occurred in a ROI (EVS_I) and or as having occurred outside of the ROI (EVS_NI). EVS_I may be considered as event data EDT and be transmitted to the processor. In Fig. 17 and 18, event signals are conditionally or non-conditionally output with regards to a region of interest ROI. [0168], with regards to figures 3 and 18, teaches that the vision sensor 100 sets the ROI and based on set conditions may either output event signals corresponding to entire region (S340) or output event signals corresponding to the ROI (S350). Seo, therefore, does teach event signals outside a ROI are also transmitted based on mode of operation [0166]. In addition, as stated in [0032], the separate vision sensor 101 generates and transmits signals corresponding to an external scene/object. Only the vision sensor 100 is generating the event signals EVS (and that also can be set to be conditional). 6. In addition, the Applicant argues/remarks that the image generation referenced in [0045] of Seo is not a fusion of image data obtained via subsets of a single pixel array with different imaging parameter value, but instead a separate sensor. 7. The examiner, respectfully, disagrees. [0045] teaches a plurality of pixels PX that may be implemented in by separate pixel array 110, where one set generates images of an object and another that may sense events. With regards to the event sensing PX, [0045] clearly teaches different imaging parameters that are set out for the event detecting pixel PX than the pixel PX which senses an external scene including an image of an object. Seo, teaches subsets of pixels PX that might be implemented in two arrays sensing different parameters of imaging. Information Disclosure Statement 8. The information disclosure statement (IDS) submitted on 06/16/2026 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 102 9. 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 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. 10.

Regarding claim 4, Seo teaches the sensor device according to claim 1 (see claim 1 above), wherein the circuitry is configured to perform the division of the plurality of pixels into the subsets of pixels randomly (…wherein [0041] teaches event signals may be selectively transmitted in a limited manner (e.g. one or some); further, even detection data is a variable of what is detected, thus random…). 15. Regarding claim 5, Seo teaches the sensor device according to claim 1 (see claim 1 above), wherein the circuitry is configured to perform the division of the plurality of pixels into the subsets of pixels at consecutive points in time based on an evaluation of previously generated final images (…wherein as stated in [0048], the event rate controller 130 may adjust an amount of the event signals thereby limit the selection from a total amount of detected event signals…). 16. Regarding claim 6, Seo teaches the sensor device [[(10)]] according to claim 5 (see claim 5 above), wherein the circuitry is configured to change the pixel ratio of the number of pixels in the different subsets based on the evaluation of the previously generated final images (…wherein [0035] teaches that different regions of interest may have varying conditions for event detection condition; as such the recognition of regions is taken into consideration, therefore this is viewed as being relative to previously generated image wherein the region is recognized…). 17. Regarding claim 7, Seo teaches the sensor device [[(10)]] according to claim 6 (see claim 6 above), wherein the circuitry is configured to segment the plurality of pixels into different areas based on the evaluation of the previously generated final images, and to divide the pixels in different areas according to different pixel ratios (…wherein [0035] teaches that different regions of interest may have varying conditions for event detection condition; [0142] further teaches that vision sensor 100 may perform motion estimation to estimate the ROI of the second frame based on the ROI of a first frame…). 18.

Claim Rejections - 35 USC § 103 25. 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 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. 26. Claims 8, 10, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Seo et al. (US 2020/0410272 A1) in view of Wong et al. (US 2021/0185264 A1). 27. Regarding claim 8, Seo teaches the sensor device according to claim 5 (see claim 5 above). Seo does not teach wherein the circuitry is configured to evaluate the previously generated final images by using a neuronal network (…however, Wong teaches an event based sensor in which a neural network is used to determine if a detected event is relative to a desired object category. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention that a neural network is implemented in which object characteristics of a detected object can be analyzed so to determine operating parameters of the image sensor; wherein as such the object recognized can be mapped as a region of interest…). 28. Regarding claim 10, Seo teaches the sensor device according to claim 1 (see claim 1 above). Seo does not further teach wherein the circuitry is configured to generate the final images by using an artificial intelligence model that receives the image data obtained via the at least two subsets of pixels during each specific time period and that outputs the final images (…however, Wong teaches image processing (for data output from an image sensor) through a neural network and artificial intelligence capabilities. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention that image processing, as taught by Wong, can be employed for advanced processing capabilities…). 29. Regarding claim 20, Seo teaches the sensor device according to claim 10 (see claim 10 above), wherein the artificial intelligence model comprises a model-aware neural network configured to decode and fuse images (…wherein Wong, in [0010], teaches that the neural network determining a detected event and thereafter a region of interest can be mapped for activation. Further, the activated region can be analyzed by the neural network for additional decision. [0048] teaches that a processor 130 can process data output of the image sensor and implement advanced processing capabilities as such neural network and artificial intelligence…). 30. Claims 12 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Seo et al. (US 2020/0410272 A1) in view of Reyserhove et al. (US 2020/0195828 A1). 31. Regarding claim 12, Seo teaches the sensor device according to claim 1 (see claim 1 above), wherein the circuitry is configured to generate as image data pixel signals indicating intensity values of the received light for each pixel (…wherein [0101] teaches vision sensor 100 may measure the amount of event signals generated in response to a change in incident light intensity; further [0146] teaches the output of a plurality of frames (FRM1-FRM4) as an event data…). Though Seo teaches detection conditions, Seo doesn’t further explicitly teach the at least one imaging parameter is one of pixel exposure time (…however, Reyserhove teaches a programmable pixel array in which [0051] teaches that different regions of an image frame are captured at different exposure periods. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention that different exposure times are attributable to different regions of interest thereby having the ability to generate more image frames through shorter exposure times, particularly in a region of interest of object tracking; thereby not using additional resources of processing outside the region of interest…). 32. Regarding claim 18, Seo in view of Reyserhove teaches the sensor device according to claim 12 (see claim 12 above), wherein the at least one imaging parameter is the pixel exposure time, and the circuitry is configured to set a first pixel exposure time for the first subset of pixels and a second pixel exposure time for the second subset of pixels, the second pixel exposure time being different from the first pixel exposure time (…wherein [0051] teaches a pixel array programming map which can stagger data measurement storage at subset level of different pixel cells in different exposure times (viewed as subsets of pixels with corresponding exposure times) allowing pixel cells of an image frame to be generated wherein different regions have different exposure periods. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention that different exposure times are attributable to different regions of interest thereby having the ability to generate more image frames through shorter exposure times, particularly in a region of interest of object tracking; thereby not using additional resources of processing outside the region of interest…). Conclusion 33. 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.
