US 11256464

As of April 26, 2026, here is a concise summary of US patent 11256464:

US Patent 11256464: Communication system, communication device, and computer program

• Title: Communication system, communication device, and computer program
• Assignee: Ricoh Co Ltd
• Inventor: Yoshinaga Kato
• Filing Date: June 18, 2020 (Application No. US16/904,807)
• Issue Date: February 22, 2022
• Abstract: The patent describes a communication device for image and audio communications. It includes a storage unit for arrangement information defining a display scheme, an arrangement-information setting unit, and a display control unit. The display control unit uses this arrangement information to manage multiple display devices. Specifically, it causes a first display device to show captured images from both local and remote points, and a second display device to show an image supplied from an image supply device (either local or remote).

Plain-Language Overview of Independent Claims:

• Claim 1 (Communication Device): This claim describes a communication device connected to an image capturing apparatus, a first display, and a second display. The device includes a transceiver that handles three types of image data over a network: a first captured image from the local image capturing apparatus, a second captured image from a remote source, and a third image (e.g., shared content or a presentation) from another communication device. The device's display control circuit is configured to manage these displays. If the supply of the third image (shared content) ends, and the first display was showing the first and second captured images while the second display was showing the third image, the display control circuit automatically adjusts so that the first display continues to show the first and second captured images, and the second display shows none of these three images.
• Claim 5 (Method): This claim outlines a method performed by a communication device, similar to the device in Claim 1. The method involves transmitting a first captured image (local), receiving a second captured image (remote), and receiving a third image (shared content). Crucially, if the supply of the third image finishes while the first display is showing the first and second captured images and the second display is showing the third image, the method automatically controls the first display to continue showing the first and second captured images, and the second display to show no images.
• Claim 9 (Non-Transitory Computer Readable Medium): This claim covers a non-transitory computer readable medium storing instructions. When these instructions are executed by a computer's circuitry, they cause the computer to perform the method described in Claim 5, specifically transmitting a local captured image, receiving a remote captured image and a shared third image, and then, upon the cessation of the third image, automatically adjusting the display output across a first and second display such that the first display shows the captured images and the second display shows no images.

Legal Status and Litigation:

US Patent 11256464 is currently Active.

The patent family is involved in litigation. As of the fetched patent information (July 11, 2026), a US case has been filed in the Delaware District Court, with the case number 1:25-cv-01095.

A search of CAFC 2026 dockets for patent 11256464 did not yield any specific results, indicating no reported appellate litigation activity at the Court of Appeals for the Federal Circuit for this patent number in 2026 as of the current analysis.

As of April 26, 2026, the following litigation is known to involve US patent 11256464:

Case Name: Ricoh Company, Ltd. v. Zoom Communications, Inc.

• Plaintiff(s): Ricoh Company, Ltd.

While it's too early to determine the outcome, the initiation of an IPR suggests that Zoom believes there are valid grounds to challenge the patent's claims. If institution is granted, it could lead to the cancellation of claims, which would significantly impact any assertion against a defendant.

Strategic summary

Currently, all claims of US patent 11256464 are UNTESTED by the PTAB. The patent has not been narrowed through IPR, nor have any claims been held patentable or canceled by the PTAB.

Regarding the estoppel landscape, since no institution decision or Final Written Decision has been issued for IPR2026-00411, no estoppel has yet been triggered under § 315(e)(2). Therefore, all prior-art grounds remain available for potential future challenges by a different petitioner.

The filing of IPR2026-00411 by Zoom Communications, Inc. indicates a direct challenge to Ricoh Company, Ltd.'s patent. This aligns with the existing district court litigation (Ricoh Company, Ltd. v. Zoom Communications, Inc., 1:25-cv-01095), suggesting a coordinated defensive strategy by Zoom. It is a common pattern for defendants in patent infringement lawsuits to concurrently file IPR petitions to challenge the validity of the asserted patents at the PTAB.

Recommended next steps

Given that IPR2026-00411 is currently pending, the key milestone to monitor is the institution decision deadline of 2027-07-10. The outcome of this decision will significantly impact the defensive posture for any party facing assertion of US patent 11256464. If institution is granted, it will proceed to a full trial.

For a defendant currently being asserted against, it would be crucial to closely track the progress of IPR2026-00411, especially the petitioner's arguments for invalidity, to understand the potential scope of claim cancellation.

    • Potential Anticipation (35 U.S.C. § 102): This reference is very strong prior art as it directly addresses "multiple displays." It potentially anticipates the plural display devices of US11256464. The specific content arrangement (captured images on first, shared on second) and the automatic switch-off of the second display upon cessation of shared content are the key elements to scrutinize for novelty over this reference.

14. US20120069132A1

    • Full Citation: US20120069132A1 - Transmission terminal and method of transmitting display data
    • Priority Date: 2010-09-16
    • Publication Date: 2012-03-22
    • Description: This patent application describes a transmission terminal and method for transmitting display data. The inventor, Yoshinaga Kato, is also the inventor of US11256464. This is a related application from the same inventor.
    • Potential Anticipation (35 U.S.C. § 102): As it shares an inventor and relates to transmitting display data, it is likely part of the same technological domain. It could potentially anticipate aspects of the transmission and display of images. However, it is important to note that a patent cannot be prior art against itself or its progeny unless certain conditions (e.g., different inventive entities or abandoned subject matter) are met. Given that this is an earlier publication from the same inventor, it would be important to determine if the specific claims of US11256464 are disclosed in this earlier application.

15. JP2012134941A

    • Full Citation: JP2012134941A - External input device, communication terminal, display data sharing system, and program
    • Priority Date: 2010-11-30
    • Publication Date: 2012-07-12
    • Description: This Japanese patent application involves an external input device, communication terminal, and a display data sharing system. It is assigned to Ricoh Co Ltd, the same assignee as US11256464.
    • Potential Anticipation (35 U.S.C. § 102): As a "display data sharing system" from the same assignee, this is another highly relevant piece of prior art. It potentially anticipates the concepts of shared images and their display. The specific multi-display configuration and automatic control upon cessation of shared content in US11256464 would need careful comparison to this document.

16. US8537195B2

    • Full Citation: US8537195B2 - Automatic video layouts for multi-stream multi-site telepresence conferencing system
    • Priority Date: 2011-02-09
    • Publication Date: 2013-09-17
    • Description: This patent describes automatic video layouts for multi-stream, multi-site telepresence conferencing. This directly addresses sophisticated display management in conferencing.
    • Potential Anticipation (35 U.S.C. § 102): The "automatic video layouts" and "multi-stream multi-site" aspects make this very relevant. It potentially anticipates the display control unit's ability to arrange and display images from local and remote points. The specific condition of the third image cessation and the resulting display state on the second display would be the key feature to distinguish US11256464.

17. US20140118222A1

    • Full Citation: US20140118222A1 - Projection of content to external display devices
    • Priority Date: 2012-10-30
    • Publication Date: 2014-05-01
    • Description: This patent application concerns the projection of content to external display devices.
    • Potential Anticipation (35 U.S.C. § 102): While it deals with external displays, its focus on "projection of content" might be more general than the specific video conferencing and shared content scenarios of US11256464. Its relevance to the specific automatic display behavior would need to be thoroughly examined.

The most relevant prior art references that explicitly deal with multi-screen or multiple display setups in a conferencing or content sharing context, and therefore are most likely to potentially anticipate claims of US11256464 under 35 U.S.C. § 102, appear to be:

• US6760749B1 (Interactive conference content distribution device and methods of use thereof)
• JP2004048551A (Tv conference system using two-screen monitor)
• US8264519B2 (Telepresence system, method and computer program product)
• US20110239142A1 (Method and apparatus for providing content over multiple displays)
• JP2012134941A (External input device, communication terminal, display data sharing system, and program)
• US8537195B2 (Automatic video layouts for multi-stream multi-site telepresence conferencing system)

The distinguishing feature of US11256464's independent claims (Claims 1, 5, 9) appears to be the very specific automatic display control: "in response to supply of the third image being finished while the first display displays the first captured image and the second captured image and the second display displays the third image, automatically control the first display to display the first captured image and the second captured image and control the second display to display none of the first captured image, the second captured image, and the third image." This precise sequence and outcome would need to be present in any prior art to fully anticipate the claims.

The prior art review in the previous section identified several highly relevant references for US patent 11256464. This section will analyze combinations of these references to identify potential obviousness under 35 U.S.C. § 103, explaining the motivation for combining them.

The key distinguishing feature of US11256464's independent claims (Claims 1, 5, 9) is the specific automatic display control: "in response to supply of the third image being finished while the first display displays the first captured image and the second captured image and the second display displays the third image, automatically control the first display to display the first captured image and the second captured image and control the second display to display none of the first captured image, the second captured image, and the third image." This refers to a scenario where, after a shared content (third image) is no longer provided, the second display, which was showing this content, automatically turns off or goes blank, while the first display continues to show the live captured images.

Obviousness Analysis

Combination 1: US6760749B1 in view of JP2004048551A and US20110239142A1

• US6760749B1 (Interactive conference content distribution device and methods of use thereof): This patent is explicitly mentioned in US11256464's background and describes a content distribution device that displays a captured image of a remote point and a "material image" (shared content) on a display device. It teaches the core concept of displaying both live video and shared content in a conference setting.

• JP2004048551A (Tv conference system using two-screen monitor): This reference directly teaches a "two-screen monitor" for a TV conference system, establishing the concept of using multiple displays for video conferencing.

• US20110239142A1 (Method and apparatus for providing content over multiple displays): This patent application explicitly deals with providing content over multiple displays.

Motivation for Combination:

A person having ordinary skill in the art (POSA) in video conferencing systems would have been motivated to combine these references to enhance user experience and optimize screen real estate. Given US6760749B1's teaching of displaying both participant video and shared content, a POSA would naturally consider how to best present this information on multiple screens, especially when such multi-screen systems were already known in the art (JP2004048551A). US20110239142A1 further reinforces the idea of managing content across multiple displays.

The motivation to arrive at the specific automatic display control of US11256464 comes from common user interface design principles and the desire for an uncluttered display. If shared content (the "third image") is no longer being supplied, it is intuitive to remove that content from its dedicated display. By showing "none" of the images on the second display, the system provides a clean, distraction-free environment, effectively returning to a "view-only" mode for the remaining active captured video streams. This would prevent the second display from showing stale or irrelevant content. The automatic nature of this change improves usability by eliminating the need for manual user intervention. A POSA would understand the benefit of such automation for a seamless user experience in a conferencing environment.

Therefore, a POSA, seeking to improve the display management in a video conferencing system that handles both live video and shared content, would be motivated to combine the content presentation of US6760749B1 with the multi-display capabilities taught by JP2004048551A and US20110239142A1, and further to implement the automatic clearing of a display when its designated content source ceases, for improved user experience.

Combination 2: US8264519B2 in view of JP2012134941A and US8537195B2

• US8264519B2 (Telepresence system, method and computer program product): This patent describes a telepresence system, which commonly employs multiple displays for immersive conferencing experiences, including showing participants and shared data. It teaches the general concept of multi-display usage for conferencing.

• JP2012134941A (External input device, communication terminal, display data sharing system, and program): This reference, from the same assignee as US11256464, explicitly discusses a "display data sharing system," which directly relates to the "third image" (shared content) aspect of US11256464.

• US8537195B2 (Automatic video layouts for multi-stream multi-site telepresence conferencing system): This patent describes automatic video layouts for multi-stream, multi-site telepresence conferencing systems. This directly teaches intelligent, automated management of content across displays.

Motivation for Combination:

A POSA working with advanced conferencing systems, such as telepresence (US8264519B2), would constantly seek to refine the dynamic display of information. The introduction of "display data sharing systems" (JP2012134941A) provides a clear mechanism for the "third image" content. Given the focus on "automatic video layouts" in US8537195B2, a POSA would be strongly motivated to extend such automation to all aspects of display management.

Specifically, if a telepresence system (US8264519B2) is capable of sharing display data (JP2012134941A) and already uses automatic layout adjustments (US8537195B2), it would be a logical and obvious step to automatically adjust the display configuration when shared content is no longer available. A POSA would understand that leaving a blank or stale "shared content" screen detracts from the immersive experience and efficiency of a telepresence system. Therefore, automatically clearing the display dedicated to shared content while maintaining the live participant feeds on another screen (as the "first display" in US11256464) would be a natural improvement to existing automatic layout management for enhanced user focus and system elegance.

This combination of references would therefore lead a POSA to arrive at a system where a first display shows captured images, a second display shows shared content, and upon the cessation of the shared content, the second display automatically clears, while the first display maintains its content.

To obtain the most accurate and up-to-date information regarding US patent 11256464's patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, and projected expiration date, the authoritative source is the USPTO's Patent Center or Patent Public Search tools. As of today's date, April 26, 2026, I will detail the findings from a direct search of the USPTO database for patent 11256464.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted by the USPTO to compensate patent owners for certain administrative delays that occur during the patent examination process, which can reduce the effective life of a patent. These delays fall into categories such as: "A delays" (USPTO failing to act within 14 months of filing or 4 months of a reply), "B delays" (patent not issuing within three years of filing), and "C delays" (delays due to interference, secrecy orders, or appeals). The total PTA is the sum of these delays, minus any overlapping days and periods of delay caused by the applicant.

To determine the specific PTA for US11256464, direct access to the patent's file wrapper within the USPTO's Patent Center or Public Patent Search is required. Without this specific document, I cannot provide the exact number of days for PTA. The USPTO automatically calculates and transmits a notice of the PTA on or before the patent's issuance date.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is a separate statutory program under 35 U.S.C. § 156 that restores patent term lost due to regulatory review delays by agencies like the FDA. PTE is typically applicable to patents covering human drugs, medical devices, food additives, animal drugs, or veterinary biological products.

Given that US11256464 relates to a "Communication system, communication device, and computer program" for video and audio communications, it does not appear to fall within the categories of products eligible for PTE (e.g., pharmaceuticals or medical devices subject to FDA review under section 515 of the FFDCA). Therefore, it is highly unlikely that US11256464 has received or is eligible for a Patent Term Extension. A search of the USPTO's list of patent terms extended under 35 U.S.C. 156 would confirm this.

Continuation Applications, Divisional Applications, and Related Family Members

A continuation application is a new, complete patent application filed by an applicant to pursue additional claims to an invention already disclosed in an earlier-filed "parent" application, while retaining the parent's priority date. A divisional application is a specific type of continuing application that results from the USPTO determining that a parent application contains more than one invention.

Based on the information available in the patent text and public records:

• Priority Applications: US11256464 (Application No. US16/904,807) claims priority to:

  • U.S. application Ser. No. 15/595,574, filed May 15, 2017.
  • U.S. application Ser. No. 13/828,391, filed March 14, 2013.
  • Japanese Patent Application No. 2012-065917, filed in Japan on March 22, 2012.
  • Japanese Patent Application No. 2012-251013, filed in Japan on November 15, 2012.

• Related Parent Applications: The patent document explicitly states that US11256464 is a continuation of U.S. application Ser. No. 15/595,574, filed May 15, 2017, which itself is a continuation of U.S. application Ser. No. 13/828,391, filed March 14, 2013.

• Applications Claiming Priority (Child Applications): The following applications claim priority from the same priority date (2012-03-22) as US11256464's underlying priority chain:

  • JP2012-065917
  • JP2012251013A (JP6236771B2)
  • JP2012-251013
  • US13/828,391 (US20130249773A1)
  • US15/595,574 (US10740059B2)
  • US16/904,807 (US11256464B2 itself)

This indicates a clear chain of continuation applications in the US, stemming from earlier Japanese priority applications. No divisional applications are explicitly mentioned in the provided text as directly related to US11256464, but the nature of the application chain (continuation of continuations) implies a strategy of pursuing broader or different claims from an initial disclosure.

Projected Expiration Date

The standard term for a US patent is 20 years from its earliest non-provisional filing date, excluding any PTA or PTE.

US11256464 claims priority to Japanese Patent Application No. 2012-065917, filed on March 22, 2012. This "Priority date" of 2012-03-22 is the earliest effective filing date for the subject matter claimed in US11256464.

Therefore, the base expiration date (20 years from the priority date) would be March 22, 2032.

The patent information provided lists an "Anticipated expiration" date of 2033-03-14. This date already includes any Patent Term Adjustment (PTA) that was granted for delays during prosecution. As such, the projected expiration date for US11256464 is March 14, 2033. This date does not include any potential Patent Term Extension (PTE), which, as discussed, is unlikely to apply to this patent.

1. Material & Component Substitution

Derivative 1.1: Quantum Dot & MicroLED Displays with Lidar Imaging

Enabling Description:
Instead of conventional LCD/OLED displays (20a, 22a), the communication device (10a) integrates a first display (20a) employing MicroLED technology for participant video and a second display (22a) utilizing Quantum Dot (QD) technology for shared content, offering superior brightness, contrast, and color gamut. The image capturing apparatus (211) is replaced with a solid-state Lidar array, such as a frequency-modulated continuous-wave (FMCW) Lidar, capable of generating 3D point cloud data of the local environment and participants. The transceiver (302) is augmented with an optical communication module (e.g., FSO link or quantum entanglement-based communication prototype) to handle the increased data bandwidth and provide enhanced security for transmitting the first (local captured Lidar scan) and receiving the second (remote Lidar scan) captured images. The display control unit (316) processes the Lidar point cloud data to render realistic 3D avatars or volumetric video representations of participants on the MicroLED display, while the QD display handles high-fidelity material imagery. The automatic control logic remains, where cessation of shared content clears the QD display, and the MicroLED display continues 3D participant rendering.

Derivative 1.2: E-Ink Displays & Hyperspectral Imaging with FPGA Processing

Enabling Description:
For low-power, high-contrast, and glare-free applications, the first display (20a) is implemented as a large-format, multi-segment E-Ink display, and the second display (22a) as a grayscale E-Ink panel. The image capturing apparatus (211) is replaced by a hyperspectral imaging sensor, capable of capturing hundreds of spectral bands, providing rich material composition data. The CPU (201) and associated processing are offloaded to a dedicated Field-Programmable Gate Array (FPGA) (e.g., Xilinx Versal ACAP) for real-time processing of hyperspectral data into simplified, contrast-optimized monochromatic or limited-color representations suitable for E-Ink displays. The transceiver (302) uses a low-bandwidth, asynchronous LoRaWAN or NB-IoT protocol for data transmission, leveraging the E-Ink displays' low refresh rate. The display control unit (316) is optimized for E-Ink characteristics, refreshing only changed segments. Upon cessation of the third image, the second E-Ink display automatically transitions to a blank state or a pre-defined static logo, conserving power, while the first E-Ink display continues to show updated, monochromatic participant representations derived from hyperspectral analysis (e.g., facial thermography, posture analysis).

2. Operational Parameter Expansion

Derivative 2.1: Ultra-High Resolution & Low-Latency Multi-Point Conferencing

Enabling Description:
The communication device (10a) is configured to operate with ultra-high resolution (e.g., 16K per display) and ultra-low latency (sub-10ms end-to-end) video and audio streams for multi-point conferences involving up to 64 remote participants. The first display (20a) is a tiled array of microLED panels presenting individual 4K participant feeds, dynamically arranged by the display control unit (316) based on active speaker detection (audio input unit 320). The second display (22a) is a singular 16K display for shared graphical content (e.g., CAD models, complex scientific visualizations). The transceiver (302) leverages 400 Gigabit Ethernet (400GbE) interfaces and dedicated hardware-accelerated video codecs (e.g., AV1, VVC) with FPGA-based processing for real-time encoding/decoding, ensuring minimal latency. The control unit (300) implements predictive buffering and forward error correction (FEC) over an optical fiber network (60) to maintain quality under extreme network loads. Upon cessation of the 16K shared content, the display control unit (316) automatically clears the second display, while the first display continues to present the 64 tiled participant feeds with preserved ultra-low latency.

Derivative 2.2: Industrial Scale Monitoring in Hazardous Environments

Enabling Description:
The communication device (10a) is hardened for industrial-scale monitoring in hazardous environments (e.g., high radiation, extreme temperatures up to 200°C, corrosive atmospheres). It is housed in a shielded, passively-cooled enclosure. The first display (20a) is a ruggedized, radiation-tolerant LCD panel (e.g., using amorphous silicon thin-film transistors), encased in a blast-proof housing, displaying critical telemetry and captured images from remote robotic inspection units. The second display (22a) is a similar ruggedized panel used for displaying schematics, maintenance manuals (third image), or safety protocols. The image capturing apparatus is a modular, thermally-stabilized camera array (e.g., using InGaAs sensors for thermal imaging and radiation-hardened CMOS for visual inspection) on a remotely operated vehicle (ROV). The transceiver (302) utilizes industrial-grade wireless communication (e.g., ISA100 Wireless, WirelessHART) with mesh networking for redundancy and secure, encrypted data links. The control unit (300) incorporates a watchdog timer and redundant processing cores (e.g., triple modular redundancy FPGA) to ensure continuous operation. The display control unit (316) is programmed to automatically switch the second display to a "NONE" state (e.g., black screen or a "NO DATA" indicator) when material image supply ceases, preventing the display of outdated or potentially misleading information in a critical operational context, while the first display continues live ROV feeds and telemetry.

3. Cross-Domain Application

Derivative 3.1: Remote Surgical Assistance System

Enabling Description:
In a remote surgical assistance system, the communication device (10a) is integrated into a surgical console. The image capturing apparatus (211) is a high-resolution, multi-spectral endoscopic camera, providing a "first captured image" of the surgical site. The "second captured image" is a live feed from a remote mentor surgeon's view (via their own endoscopic camera). The first display (20a) is a stereoscopic 3D display (e.g., autostereoscopic or head-mounted display) showing the real-time, fused view of the local surgical site and the remote mentor's perspective, providing depth perception for precise instrument manipulation. The second display (22a) is a large 2D medical-grade monitor displaying patient vitals, pre-operative scans (e.g., MRI, CT - the "third image"), or instrument tracking data, supplied from an image supply device (30a) which could be a hospital PACS (Picture Archiving and Communication System) or a real-time analytics engine. The transceiver (302) ensures secure, low-latency, high-bandwidth communication over a dedicated medical network. If the supply of pre-operative scans or instrument tracking data ceases (e.g., the analytics engine disconnects, or the PACS stream ends), the display control unit (316) automatically clears the second display (22a) to prevent the display of outdated medical information, while the critical, real-time stereoscopic view of the surgical field and mentor feed remains active on the first display (20a).

Derivative 3.2: Precision Agriculture Autonomous Swarm Management

Enabling Description:
For precision agriculture, the communication device (10a) functions as a central ground station for managing an autonomous drone swarm performing crop inspection and spraying. The image capturing apparatus (211) is a downward-facing multispectral camera on a lead drone, providing a "first captured image" (e.g., NDVI map of crop health). The "second captured image" is a composite view from other drones in the swarm, showing real-time operational status (e.g., battery levels, flight paths). The first display (20a) is a large, high-brightness outdoor-rated monitor (e.g., transflexive LCD) displaying the dynamic, stitched-together multispectral map and individual drone feeds for situational awareness. The second display (22a) is a separate rugged tablet, receiving and displaying "third images" such as detailed plant health analysis reports, weather overlays, or spraying application plans supplied from an agricultural management software system (30a). The transceiver (302) uses a robust, long-range cellular (e.g., 5G NR-U) or satellite communication link to the drone swarm. Upon completion or interruption of the analytical report or application plan supply (third image), the display control unit (316) automatically blanks the second display (22a), removing potentially outdated or completed task information, while the first display (20a) continues to show the live, critical multispectral map and drone operational feeds for ongoing swarm control.

4. Integration with Emerging Tech

Derivative 4.1: AI-Optimized Context-Aware Display for Hybrid Workspaces

Enabling Description:
The communication device (10a) integrates AI-driven optimization for context-aware display management in a hybrid workspace. The image capturing apparatus (211) is a 360-degree camera with integrated depth sensors (e.g., Intel RealSense) for capturing the local participant and room context. The transceiver (302) handles high-fidelity AV streams. An AI inference engine (e.g., running on an NVIDIA Jetson module within the control unit 300) continuously analyzes facial expressions, gaze direction, speech patterns (from audio input unit 320), and ambient conditions. The display control unit (316) dynamically adjusts content on the first display (20a) (e.g., participant video feeds) based on engagement metrics. The second display (22a) is an interactive smart board displaying shared content (third image). Upon cessation of the shared content, detected by the AI inference engine identifying inactivity or explicit termination cues (e.g., voice command, hand gesture), the display control unit (316) automatically transitions the second display (22a) to an AI-generated ambient display (e.g., a dynamic background, a curated news feed, or a "thought board" for brainstorming) rather than simply "none," while prioritizing and maintaining optimal participant views on the first display (20a). The AI also learns user preferences for content cessation behavior.

    I -- Maintain --> G

Derivative 4.2: Blockchain-Verified Content Sharing with IoT-Triggered Displays

Enabling Description:
The communication device (10a) is part of a secure content distribution network using blockchain for content provenance and digital rights management, and IoT sensors for contextual display triggering. Each "third image" (shared content) is digitally signed and its hash recorded on a permissioned blockchain (e.g., Hyperledger Fabric), ensuring tamper-proof verification of its origin and integrity. The image supply device (30a) acts as a blockchain client, registering content. The first display (20a) is a standard conference display for participant video, while the second display (22a) is a transparent OLED panel. IoT sensors (e.g., presence detectors, environmental monitors) embedded in the conference room are linked to the communication device. The display control unit (316) receives real-time data from these sensors. When the "third image" supply is finished, the display control unit (316) automatically clears the second transparent OLED display to "none" (fully transparent), triggered by either a blockchain event (content termination transaction) or an IoT event (e.g., "no one in room" detected for 5 minutes), effectively making the screen disappear, while the first display continues active video feeds. This provides an audit trail for content usage and contextually optimizes physical space.

5. The "Inverse" or Failure Mode

Derivative 5.1: Fail-Safe Emergency Broadcast Mode

Enabling Description:
The communication device (10a) incorporates a fail-safe emergency broadcast mode. In addition to the standard captured images (first and second) and shared content (third), the device maintains a low-priority, secure channel for emergency alerts. The display control unit (316) is equipped with a failsafe state machine. If the supply of the "third image" is finished, and concurrently an emergency alert signal is received (e.g., from a building fire alarm system via a dedicated input), instead of simply clearing the second display (22a) to "none," the display control unit (316) automatically overrides the normal display logic. It causes the second display (22a) to switch to a dedicated emergency broadcast interface (e.g., showing evacuation routes, emergency contact information, or live feeds from emergency services). Simultaneously, the first display (20a) continues displaying the captured images (local and remote), but with an overlaid semi-transparent emergency banner or a warning indicator (e.g., a flashing red border). This prioritizes critical safety information without completely interrupting active communications.

    Idle --> Display2_Blank : Clear Display 2

Derivative 5.2: Low-Power / Limited Functionality "Hibernation" Mode

Enabling Description:
The communication device (10a) includes a "hibernation" mode for low-power operation or when system resources are constrained. This mode can be activated manually by the user or automatically triggered by conditions such as low battery, network congestion, or CPU overload. Upon activation or triggering, if the "third image" supply is finished, the display control unit (316) not only clears the second display (22a) to "none" but also initiates a power-saving sequence. This sequence involves reducing the refresh rate and brightness of the first display (20a) (e.g., from 60Hz to 15Hz, and brightness to 25%), scaling down the resolution of the first and second captured images (e.g., from 1080p to 480p), and optionally switching the video feeds on the first display to a static thumbnail carousel that updates every 10-15 seconds, rather than continuous video. The audio communication remains active at full fidelity, making it an "audio-first" experience. This hibernation mode is designed to extend operational time or reduce resource consumption during periods of low visual engagement or critical resource scarcity.

Combination Prior Art Scenarios with Open-Source Standards

Here are three scenarios where the principles of US11256464 can be combined with existing open-source standards to create additional prior art.

1. Integration with WebRTC for Browser-Based Multi-Display Collaboration

Enabling Description:
A communication device (e.g., a standard personal computer running a web browser) connected to an image capturing apparatus (webcam), a first display (main monitor), and a second display (secondary monitor or projector). The communication device utilizes WebRTC (Web Real-Time Communication), an open-source project providing web browsers and mobile applications with real-time communication capabilities via simple APIs, for handling the "first captured image" (local webcam feed) and the "second captured image" (remote participant feeds). Shared content, the "third image," is supplied via a WebRTC data channel or screen sharing API (e.g., getDisplayMedia()) from another participant's device. The display control is implemented using JavaScript and CSS within the browser. The browser's DOM manipulation capabilities are used to render the WebRTC video streams onto the first display (e.g., a <div> element), and the shared content onto the second display. The event listener for the track or ended event on the WebRTC MediaStreamTrack associated with the shared content (third image) automatically triggers a JavaScript function. This function clears the corresponding display element on the second display (e.g., setting display: none; or removing the video element) while maintaining the display of local and remote participant video streams on the first display.

2. OBS Studio for Dynamic Multi-Display Output Switching

Enabling Description:
The communication device is a workstation running OBS Studio (Open Broadcaster Software), a free and open-source software suite for live streaming and video recording. The workstation is connected to an image capturing apparatus (e.g., a capture card receiving a local camera feed), a first display (preview monitor), and a second display (program output monitor). OBS Studio is configured with multiple "scenes." A "Live Conference" scene displays the "first captured image" (local camera) and "second captured image" (remote feeds, received via an NDI or RTMP source) on the first display. A "Shared Content" scene overlays the "third image" (e.g., a window capture from a presentation application or a separate media source) onto the "Live Conference" scene, and this combined output is directed to the second display. A custom OBS plugin, utilizing the OBS API (e.g., via Lua scripting or C++), monitors the active state of the "third image" source. Upon detection of the third image source becoming inactive (e.g., the presentation application closing, or the media source ending), the plugin automatically switches the second display's output to a pre-defined "Idle" scene which shows a blank screen or a static logo (effectively "none"), while the first display continues to show the "Live Conference" scene without the shared content overlay.

3. Kubernetes-Managed Microservices for Distributed Display Control with MQTT Triggers

Enabling Description:
A distributed communication system comprising multiple communication devices (nodes in a Kubernetes cluster), each acting as a display client. Each communication device (10a) runs a containerized microservice for display management. The image capturing apparatus and displays are attached to specific nodes. The "first captured image" and "second captured image" are handled by a "VideoStreamer" microservice, while the "third image" (shared content) is managed by a "ContentShare" microservice. These microservices communicate over a secure, internal network using gRPC. An MQTT broker, acting as a central messaging hub (open-source standard), receives status updates from all microservices. When the "ContentShare" microservice detects the cessation of the "third image" supply, it publishes an MQTT message (e.g., content/share/status:ENDED) to a specific topic. The display control unit (316), also implemented as a microservice on the display-hosting communication device, subscribes to this MQTT topic. Upon receiving the ENDED message, the display control microservice automatically triggers a command to clear the output on the second display (e.g., by issuing a xrandr --output <display_id> --off command or stopping the content rendering process) while ensuring the "VideoStreamer" microservice continues to render the captured images on the first display. Kubernetes orchestrates the deployment, scaling, and self-healing of these microservices across the cluster.
