Claim Status This Office Action is in response to communications filed on 03/28/2025. Claims 1-20 are pending for examination. Claim Rejections - 35 USC § 102 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 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. Claims 1-3, 4, 7-9, 11-12, 13-15, 18-19 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fu et al. (U.S. Patent 10,750,128). Regarding claims 1 and 11, Fu discloses a door system / door lock system (Figs 1-13) configured to be integrated with or coupled to a door (col 1:17-18; method and/or apparatus for implementing wireless integration of security camera and door lock), the door system comprising: a controller configured to communicate with a motor to control a lock for the door (col 5:6-8; with authentication, the voice commands may be configured to provide wireless control of various network-connected devices (e.g., door locks, garage door openers; Examiner notes that the motor is inferred), the controller configured to: receive an indication of a trigger event associated with the door (col 10:13-15; visitor 50 may be detected based on the seashell effect of a visitor shape on resonances of the environment (e.g., porch resonance)); responsive to receipt of the indication of the trigger event, initiate control of an audio device to collect a first dataset (col 21:65 – col 22:18; instructions 352 may combine a greeting with a request for information. For example, the instructions 352 may be, “Good morning, may I have your name? And how can I help you?” “Good evening, I see your cell phone MAC address. How are you?” The declaration that information has been collected may further deter a potential criminal. In still another example, the instructions 352 may provide context-aware intelligent conversation such as “It is 1 am and 40 degrees cold here, how can I help you?” The conversational AI may prompt the visitor 50 to respond in order to perform voice analysis and/or receive commands; also see col 10:16-20; an active swept frequency audio stimulus may be presented by the speaker (e.g., a bat ear echo detection). Ultrasonic, near ultrasonic and/or an audible chirp may be emitted and the return signal may be analyzed to determine dimensions of the visitor 50 and/or if the visitor 50 is carrying a package); provide, via the audio device, responsive to initiation of control of the audio device, a prompt to provide an audio input (col 21:65 – col 22:18; instructions 352 may combine a greeting with a request for information. For example, the instructions 352 may be, “Good morning, may I have your name? And how can I help you?” The reply 354a may be analyzed for a specific name as the passphrase 364i... conversational AI may prompt the visitor 50 to respond in order to perform voice analysis and/or receive commands); terminate collection of the first dataset based on criteria associated with the audio input (The user 50 may provide the vocal reply 354a. The vocal reply 354a may be analyzed to determine a vocal format/pattern and compared to the stored values 364e. In another example, the instructions 352 may request a passphrase and the vocal reply 354a may be analyzed for keywords to compare to the passphrase of the stored values 364i. The instructions 352 may further request that the visitor 50 perform a specific gesture (e.g., a wave; Examiner interprets moving on to a second request for response of a different type as being equivalent to terminating collection of first requested audio response data). or the trigger event (optionally not selected by Examiner); and transmit the first dataset to an external device for processing by the external device (col 3:22-47; devices 102a-102n may be configured to communicate the sensor data and/or the inferences made in response to performing sensor fusion operations on the sensor data to the remote device 104 and/or the user devices 106a-106n via the network 60. The devices 102a-102n may operate independently of the network 60 (e.g., without instructions from the remote device 104 and/or the user devices 106a-106n). Communication with the remote device 104 and/or the user devices 106a-106n may enhance the capabilities of the devices 102a-102n.

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. Claims 5 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Fu et al. (U.S. Patent 10,750,128) in view of Everett (WO 2021092676). (¶000 Regarding claims 5 and 16, Fu discloses the door system of claim 1 / the door lock system of claim 11, but Fu is silent on wherein the first dataset is transmitted via Ultra Low Energy (ULE) specifications. Everett from an analogous devices communication art discloses the concept wherein the first dataset is transmitted via Ultra Low Energy (ULE) specifications (¶099; Pressure or force (or other sensor-based) data from the input device may be transmitted via a low-profile, ultra-low energy wireless protocol to an output device).Therefore, it would have been obvious for one of ordinary skill in the art at the time of filing the invention to combine the door/lock system of Fu with the concept wherein the first dataset is transmitted via Ultra Low Energy (ULE) specifications, as taught by Everett transmit sensor data in order to transmit sensor/sensed data via a low-profile, ultra-low energy wireless protocol to an output device. Claim 6 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Fu et al. (U.S. Patent 10,750,128) in view of Casarez et al. (U.S. Patent Application Pub. 2021/0191236). Whitley. (U.S. Patent Application Pub. 2023/0162549). Regarding claims 6, Fu discloses the door system of claim 1, and Fu is silent on the features in claim 6. Casarez from an analogous visual indicator art teaches wherein the controller (¶043 includes a recording indicator 658 located at image side of camera aperture. recording indicator 658 may include two or more light sources (e.g., LEDs) arranged around the outer edge of a glass or plastic element 659 (e.g., a glass or plastic plate) located at the image side of the camera aperture, also see LED recording indicators ¶047-¶049) is configured to: control one or more light emitting diodes (LEDs) to provide a visual output to indicate initiation of the collection of the first dataset (¶057-¶062 and ¶077-¶079). and terminate, responsive to an amount of time exceeding a predetermined threshold, the visual output to indicate an end to the collection of the first dataset (¶055; Conventional video recording systems (e.g., conventional handheld video cameras) may include indicators (e.g., red or green LED lights) that are turned on when the cameras are recording video, and turned off when the cameras are not recording video. These recording indicators signal to persons in the environment that the video recording system is (or is not) recording video of the environment in front of the camera. Therefore, it would have been obvious for one of ordinary skill in the art at the time of filing the invention to combine the door/lock system of Fu with the concept of controlling one or more light emitting diodes (LEDs) to provide a visual output to indicate initiation of the collection of the first dataset, as taught by Casarez in order to visually indicate to users an active state of a collection of data. Fu and Casarez are both silent on being responsive to an amount of time exceeding a predetermined threshold. Whitley teaches the concept of responsive to an amount of time exceeding a predetermined threshold terminating an LED (¶107; a visual indicator, (e.g., an LED light, or other indicator) may provide a visual indication to the user that the threshold period of time has been exceeded and that a status of the host device has been changed. Therefore, it would have been obvious for one of ordinary skill in the art at the time of filing the invention to further combine the door/lock system of Fu and Casarez with the concept of being terminating an LED output after a specific amount of time has passed, as further taught by Whitley in order to provide user’s a limited time for their input in order to reduce power usage in the system. Regarding claim 17, Fu teaches the door lock system of claim 11, and Fu is silent on the features in claim 17. Casarez from an analogous visual indicator art teaches wherein the controller (¶043 includes a recording indicator 658 located at image side of camera aperture. recording indicator 658 may include two or more light sources (e.g., LEDs) arranged around the outer edge of a glass or plastic element 659 (e.g., a glass or plastic plate) located at the image side of the camera aperture, also see LED recording indicators ¶047-¶049) is configured to: control one or more light emitting diodes (LEDs) to provide a visual output to indicate initiation of the collection of the audio input (¶057-¶062 and ¶077-¶079) and terminate, responsive to an amount of time exceeding a predetermined threshold, the visual output to indicate an end to the collection of the audio input (¶055; Conventional video recording systems (e.g., conventional handheld video cameras) may include indicators (e.g., red or green LED lights) that are turned on when the cameras are recording video, and turned off when the cameras are not recording video. These recording indicators signal to persons in the environment that the video recording system is (or is not) recording video of the environment in front of the camera. Therefore, it would have been obvious for one of ordinary skill in the art at the time of filing the invention to combine the door/lock system of Fu with the concept of controlling one or more light emitting diodes (LEDs) to provide a visual output to indicate initiation of the collection of the audio input, as taught by Casarez in order to visually indicate to users an active state of a collection of data. Fu and Casarez are both silent on being responsive to an amount of time exceeding a predetermined threshold. Whitley teaches the concept of responsive to an amount of time exceeding a predetermined threshold terminating an LED (¶107; a visual indicator, (e.g., an LED light, or other indicator) may provide a visual indication to the user that the threshold period of time has been exceeded and that a status of the host device has been changed. Therefore, it would have been obvious for one of ordinary skill in the art at the time of filing the invention to further combine the door/lock system of Fu and Casarez with the concept of being terminating an LED output after a specific amount of time has passed, as further taught by Whitley in order to provide user’s a limited time for their input in order to reduce power usage in the system. Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Fu et al. (U.S. Patent 10,750,128) in view of Casarez et al. (U.S. Patent Application Pub. 2021/0191236). Whitley. (U.S. Patent Application Pub. 202/30162549). Regarding claims 10, Fu discloses the door system of claim 1, and Fu further discloses comprising one or more non-transitory computer-readable storage media storing instructions thereon that, when executed by one or more processors ( col 31:65 – col 32:2; may also include a computer product which may be a storage medium or media and/or a transmission medium or media including instructions which may be used to program a machine to perform one or more processes or methods in accordance with the invention; also see col 32:2-17) of the external device (col 2:18-36; elements of the invention may form part or all of one or more devices, units, components, systems, machines and/or apparatuses). The remainder of the claim is interpreted and rejected the same as claim 19 above, including all the claimed features except for the specific reference made to the device being an “external device”. However, since Fu explicitly further teaches that elements of the invention may form part or all of one or more devices, units, components, systems, machines and/or apparatuses and that the devices may include, but are not limited to, servers, workstations, storage array controllers, storage systems, personal computers, laptop computers, notebook computers, palm computers, cloud servers, personal digital assistants, portable electronic devices and that those skilled in the relevant art(s) would understand that the elements of the invention may be implemented in other types of devices, as well, to meet the criteria of a particular application (col 2:18-36). A person of ordinary skill in the art, upon reading the reference, would also have recognized the desirability of improved methods and/or systems whereby an external smart device with a memory means can functionally perform the same functions as an internal smart device with like memory in a given system since elements of the system may form part or all of one or more devices, units, components, systems, machines and/or apparatuses and that the devices may include, but are not limited to, servers, workstations, storage array controllers, storage systems, personal computers, laptop computers, notebook computers, palm computers, cloud servers, personal digital assistants, portable electronic devices. Likewise, a controller may be installed in a finite number of solutions where the controller is either mounted remotely away from the door, on the outside of the door, or partially dispersed/shared within/amongst different components mounted remotely away and on the outside of the door. One of ordinary skill in the art would have had good reason to position a non-transitory computer-readable storage media storing instructions thereon that, when executed by one or more processors in the external device simply as a physical means of structural protection and also protection from environmental factors. It would require no more than "ordinary skill and common sense," to utilize the non-transitory computer-readable storage media of the external device. Thus it would have been obvious for one of ordinary skill in the art at the time of filing the invention to try using the non-transitory computer-readable storage media of the external device, as a person with ordinary skill would have good reason to pursue known options within his or her technical grasp.
