Office Action

§103
DETAILED ACTION Response to Amendment The amendments, filed on 06/10/2026, have been entered and made of record. Claims 1-20 are pending. Response to Arguments 2. Applicant's arguments with respect to claims 1-20 have been considered but are moot in view of the new ground of rejection. Applicant representative further argues that: “Examiner relies on Bilodeau for teaching a device having a multiplane configuration, citing Fig. 3 (display 304 or pixels in sensor 311); [0088-0094]; Figs. 7-8D (Photodiodes 703-714, LED 702, 824); and Fig. 9 (Photodetectors 903 or inhibitory photodetectors 904). Applicants respectfully submit that the cited portions of Bilodeau describe components arranged in a single plane. For example, display 304 and sensor 311 of Fig. 3 are shown in a single plane. Similarly, photodiodes 703-714, and LED 702, 824 of Figs. 7-8D are also shown in a single plane. Additionally, in Fig. 9, a single plane of optical neurons is shown, where paired photodetectors 903 and inhibitory photodetectors 904 of the neurons are used for optical weighting purposes as detailed for example in [0139] and [0142]”. Examiner respectfully disagrees. The claim language does not require the “multiplane configuration” to be placed in separate planes, surfaces or different coordinates. By definition: multiplane consisting of serval planes or surfaces. In this case OLED having “organic layer” may comprise single layer or multiple layers ([0058]). Thus each “organic layer” of the OLED consist of different surfaces stacking together. Furthermore, each of the following elements are placed on one or more surfaces: pixels Display 304, pixels in Sensor 311, OLED pixel arrays, individual/ sub pixels of LCD display; Fig. 7-8D: Photodiodes 703-714; LED 702; 824; Fig. 9: photodetectors 903. Therefore, Bilodeau still read on the claim invention. Claim Rejections - 35 USC § 103 3. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1-2, 4-10 and 13-20 are rejected under 35 U.S.C. 103 as being unpatentable over Bilodeau (US2021/0192330) in view of Gigot (US9906722). Regarding claim 1, Bilodeau discloses a device, comprising: a plurality of optically connected networked smart pixels positioned in one or more planes (Fig. 3: See pixels Display 304 or pixels in Sensor 311; [0088-0094]: See OLED pixel arrays that could implemented as “retina-like” and individual/ sub pixels of LCD display; Fig. 7-8D: Photodiodes 703-714; LED 702; 824; Fig. 9: photodetectors 903 or inhibitory photodetectors 904); one or more imaging sensors connected to at least a portion of the smart pixels (Fig. 3: See CPU/GPU that are connected to sensing/computing layer 311 or display 304 that are comprising plurality of photodetectors, image sensor pixels and display pixels; [0089-0090]); and wherein the device is configured to perform processing on the plane where an image is captured ([0026; 0089-0096]). However, Bilodeau fails to explicitly disclose: “wherein the device is configured as a wake-up mechanism based on a trigger event”. In an analogous of art, Gigot teaches micro controller MCU 106 that receives one or more trigger event signals MINPUT_A to MINPUT_N and generate signal WAKE_UP to activate the image processor 100. The image processor 100 may activate the image capture sensor 110 and/or begin analyzing the video frames (col. 10, ln. 65-col. 11, ln. 3). In light of the teaching from Gigot, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the trigger event signal MINPUT_A to MINPUT_N to generate WAKE_UP signal. The modification thus provide a means for waking up a processor to analyze a video frame (Gigot: col. 10, ln. 65-col. 11, ln. 3). Regarding claim 2, Bilodeau in view of Gigot discloses the device of claim 1, wherein the wake-up mechanism is configured to energize a processor interpreting images from a camera (Bilodeau: Abstract; [0017; 0026; 0130-0136]: See inputs 811 from a camera wherein the activation of optical output when a signal received at an input of one or more nonlinear elements rise; Gigot: col. 10, ln. 65-col. 11, ln. 3: WAKE_UP signal is generated to wake processor 100 to analyze video frames). Regarding claim 4, Bilodeau discloses the claimed invention except for “wherein the device is configured to perform completed reduced readout from the camera and processing when required to reduce latency by 25% to 99.9% and power consumption by 25% to 99.9%”. It would have been obvious to one of ordinary skill in the art at the time the invention was made to “reduce latency by 25% to 99.9% and power consumption by 25% to 99.9%”, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Regarding claim 5, Bilodeau discloses the device of claim 1, wherein the smart pixels comprise an output configured to be conditioned by one or more received inputs (Fig. 7-8D: See output of PD703-714 in response to external input light 716, 701 or 715), wherein the smart pixels evolve over time based on the values of other pixels the smart pixel is connected to (Abstract; [0017; 0026; 0130-0136]: See the activation of optical output overtime when a signal received at an input of one or more nonlinear elements rise), wherein the evolution of the smart pixels is driven by local photocurrents and other input signals ([0030-0031; 0017-0124; 00137]: See current used to drive LEDs or output by photodiodes), and wherein a subset of the smart pixels is reserved for non-image processing tasks (Abstract; [0017; 0026; 0130-0136]: See the input of one or more nonlinear elements that determine the activation of one or more optical output; [0139; 0142]: See also inhibitory photodetectors 904). Regarding claim 6, Bilodeau discloses the claimed invention except for “ wherein the device is configured to reduce the amount of readout data required by 25% to 99.9% and to reduce a time that the processor utilizes to interpret the images by 50% to 99.9%”. It would have been obvious to one of ordinary skill in the art at the time the invention was made to “reduce the amount of readout data required by 25% to 99.9% and to reduce a time that the processor utilizes to interpret the images by 50% to 99.9%”, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Regarding claim 7, Bilodeau discloses a system, comprising: the device of claim 1 (See the rejection of clam 1); and a computing system communicatively connected to the device, comprising the processor and a non-transitory computer-readable medium ([0071-0072; 0089; 0115]) with instructions stored thereon, which when executed by the processor, perform steps comprising: performing processing on the image plane where the image is captured ([0026; 0089-0096]). Regarding claim 8, Bilodeau discloses a product comprising the device of claim 1 (See the rejection of clam 1), the product selected from the group consisting of a flat panel display, a curved display, a computer monitor, a computer, a medical monitor, a television, a billboard, a light for interior or exterior illumination and/or signaling, a heads-up display, a fully or partially transparent display, a flexible display, a rollable display, a foldable display, a stretchable display, a laser printer, a telephone, a mobile phone, a tablet, a phablet, a personal digital assistant (PDA), a wearable device, a laptop computer, a digital camera, a camcorder, a viewfinder, a micro-display, a 3-D display, a virtual reality or augmented reality display or device, a vehicle, a video wall comprising multiple displays tiled together, a theater or stadium screen, a light therapy device, a camera, an imaging device, and a sign ([0004; 0062; 0089-0091]: See display, PDAs, computers or all other display devices). Regarding claim 9, Bilodeau discloses a method, comprising: providing the system of claim 7 (See the rejection of claim 7); and performing processing on the image plane where the image is captured ([0026; 0089-0096]). Regarding claim 10, Bilodeau discloses the method of claim 9, wherein the processing comprises local processing of data where it is acquired before readout ([0090; 0137; 0139]). Regarding claim 13, Bilodeau discloses a device, comprising: a plurality of optically connected networked smart pixels positioned in a multiplane configuration (Fig. 3: See pixels Display 304 or pixels in Sensor 311; [0088-0094]: See OLED pixel arrays that could implemented as “retina-like” and individual/ sub pixels of LCD display; Fig. 7-8D: Photodiodes 703-714; LED 702; 824; Fig. 9: photodetectors 903 or inhibitory photodetectors 904; The claim language does not require the “multiplane configuration” to be placed in separate plane surfaces or different coordinates. By definition: multiplane consisting of serval planes or surfaces. In this case OLED having “organic layer” may comprise single layer or multiple layers: [0058]. Thus each “organic layer” of the OLED consist of different layer stacking together), wherein each of the plurality of smart pixels comprises an output configured to be conditioned by one or more received inputs (Fig. 7-8D: See output of PD703-714 in response to external input light 716, 701 or 715); and wherein the smart pixels evolve over time based on the values of other pixels and smart nodes the smart pixel is connected to (Abstract; [0017; 0026; 0130-0136]: See the activation of optical output overtime when a signal received at an input of one or more nonlinear element rise); wherein the evolution of the smart pixels is driven by local photocurrents ([0030-0031; 0017-0124; 00137]: See current used to drive LEDs or output by photodiodes); wherein the device is configured for image processing ([0026; 0089-0096]). Regarding claim 14, Bilodeau discloses the device of claim 13, wherein the smart pixels are configured to implement different network topologies by formatting arbitrary input data as a spatially-resolved optical intensity image ([0106; 0126]), and wherein non-image inputs are directly provided to the smart pixels ([0139; 0142]: See inhibitory photodetectors 904). Regarding claim 15, Bilodeau discloses the device of claim 13, wherein at least a portion of the smart pixels comprise light- emitting smart pixels configured to display an image, and wherein at least a portion of the smart pixels comprise optical emitters ([0089-0094; 0122]) and non-planar synaptic elements ([0139; 0142]: See inhibitory photodetectors 904). Regarding claim 16, Bilodeau discloses a system, comprising: the device of claim 13 (See the rejection of claim 13); and a computing system communicatively connected to the device ([0062; 0074; 0089), comprising a processor and a non-transitory computer-readable medium ([0089-0092]: See computing units/layers/computer or computing network or CPU/GPU/IMU/ AI-Processor in fig. 3) with instructions stored thereon, which when executed by a processor, perform steps comprising: performing processing of physically-separated inputs on the device (See separate input light that hit the photodetectors 703-714 and further process to block 708 in Fig. 7; [0134- 0135]: See also separate input from independently wired photodetector 824 that are processed to control the LEDs; [0090; 0114-0115]: neural network process 2D data arrays); wherein the system comprises a multiplane neural network ([0016-0033]) configured to perform stereoscopic image processing or processing of images received from multiple independent cameras ([0026; 0089-0096]). Regarding claim 17, Bilodeau discloses the system of claim 16, further comprising a cellular neural network with smart nodes on a plane, having arbitrary neighborhoods ([0081]), and wherein the arbitrary neighborhoods include nearest neighbors or beyond nearest neighbors on a single plane ([0134- 0135]: See also separate input from independently wired photodetector 824 that are processed to control the LEDs) or on different planes ([0082]: See different types of neuron networks). Regarding claim 18, Bilodeau discloses the system of claim 16, wherein the system is configured to perform neural processing of physically-separated inputs ([0134- 0135]: See also separate input from independently wired photodetector 824 that are processed to control the LEDs; [0090; 0114-0115]: neural network process 2D data arrays) or optical communication links ([0074]). Regarding claim 19, Bilodeau discloses a product comprising the device of claim 13 (See the rejection of claim 13), the product selected from the group consisting of a flat panel display, a curved display, a computer monitor, a computer, a medical monitor, a television, a billboard, a light for interior or exterior illumination and/or signaling, a heads-up display, a fully or partially transparent display, a flexible display, a rollable display, a foldable display, a stretchable display, a laser printer, a telephone, a mobile phone, a tablet, a phablet, a personal digital assistant (PDA), a wearable device, a laptop computer, a digital camera, a camcorder, a viewfinder, a micro-display, a 3-D display, a virtual reality or augmented reality display or device, a vehicle, a video wall comprising multiple displays tiled together, a theater or stadium screen, a light therapy device, a camera, an imaging device, and a sign ([0004; 0062; 0089-0091]: See display, PDAs, computers or all other display devices). Regarding claim 20, Bilodeau discloses a processing method, comprising: providing the system of claim 16; and performing processing of physically-separated inputs ([0134- 0135]: See also separate input from independently wired photodetector 824 that are processed to control the LEDs; [0090; 0114-0115]: neural network process 2D data arrays). Claims 3 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Bilodeau in view of Gigot and further in view of Wu (US2021/0344881). Regarding claim 3, Bilodeau in view of Gigot fails to disclose the device of claim 2, wherein the device is configured as an event camera to determine when the processor should be energized from stand-by mode into operational mode to provide real time interpretation of the camera image. In an analogous of art, Wu teaches if at least one pixel value changes, an event camera transmits a trigger signal to wake up the digital processing circuit which is in the power saving mode (abstract; [0066]; claim 6). Wu further teaches when the intensity variation is greater than the predefined value, the comparator 90 can generate the alarm signal utilized to awake the processor 84 and when the processor 84 is operated in the wakeup mode, a real-time image 12 captured by the sensor array 86 is directly transmitted to the processor 84 for digital processing. The processor 84 in the wakeup mode may process the real-time image 12 ([0042-0043]). In light of the teaching from Wu, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the event camera or comparator circuitry to wake a processor. The modification thus provide a means for waking up a processor in power saving mode to process real-time image (Wu: abstract; [0066; 0042-0043]). Regarding claim 12, Bilodeau discloses a low power video system comprising: an edge processor ([0089]: Bilodeau teaches The sensor data may then be relayed to an image processing algorithm 306, a motion tracker, edge detector, or the like, which extracts visual or positional data from the raw data received from the sensors an edge detector or the like. Therefore, the CPU/ AI Processor/ IMU in Fig. 3 is also an edge processor for process raw data from the edge detector); and a camera comprising an in-plane neural network processor (Bilodeau: [0090-0103), configured to perform real time preprocessing of the video signal to select when the edge processor is energized (Bilodeau: [0114]). However, Bilodeau in view of Gigot fails to disclose “processor configured to perform real time preprocessing of the video signal to select when the edge processor is energized; wherein the edge processor is in stand-by mode when not selected by the preprocessor”. In an analogous of art, Wu teaches if at least one pixel value changes, an event camera transmits a trigger signal to wake up the digital processing circuit which is in the power saving mode (abstract; [0066]; claim 6). Wu further teaches when the intensity variation is greater than the predefined value, the comparator 90 can generate the alarm signal utilized to awake the processor 84 and when the processor 84 is operated in the wakeup mode, a real-time image 12 captured by the sensor array 86 is directly transmitted to the processor 84 for digital processing. The processor 84 in the wakeup mode may process the real-time image 12 ([0042-0043]). In light of the teaching from Wu, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the event camera or comparator circuitry to wake a processor. The modification thus provide a means for waking up a processor in power saving mode to process real-time image (Wu: abstract; [0066; 0042-0043]). Bilodeau discloses the claimed invention except for “an in-plane neural network processor configured to provide a fast response time and low latency signal within 1 ps to 10 ms”. It would have been obvious to one of ordinary skill in the art at the time the invention was made to “to provide a fast response time and low latency signal within 1 ps to 10 ms”, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Bilodeau in view of Gigot and further in view of Godlieb (US2018/0111278). Regarding claim 11, Bilodeau in view of Gigot fails to explicitly disclose the method of claim 9, further comprising at least one of: offloading general processing to an external processor when a specific signature is detected; and offloading partially processed data to reduce later processing steps the amount of data to transfer. In an analogous of art, Godlieb teaches an internal signal processing module 206 for detecting relevant audio signals and then offloading some or all of the signal processing described below to an external entity such as an external server (comprising one or more server units at one or more geographical sites) which returns the result to the signal processor 206 on the user terminal 200 ([0046]). In light of the teaching from Godlieb, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to detect relevant audio signal. The modification thus provide a means for detecting the relevant audio signals and then offloading some or all of the signal processing described below to an external entity such as an external server (Godlieb: [0046]). 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).
