Abstract: An electronic meeting tool and method for communicating arbitrary media content from users at a meeting comprises a node configuration means adapted to operate a display node of a communications network, the display node being coupled to a first display. The node configuration means is adapted to receive user selected arbitrary media content and to control display of the user selected arbitrary media content on the first display. A peripheral device adapted to communicate the user selected arbitrary media content via the communications network is a connection unit comprising a connector adapted to couple to a port of a processing device having a second display, a memory and an operating system, and a transmitter. A program is adapted to obtain user selected arbitrary media content, said program leaving a zero footprint on termination. The user may trigger transfer of said user selected arbitrary media content to said transmitter.

Independent Claims Overview:

• Claim 1 (Method for communicating media content): This claim describes a method for facilitating the sharing of user-selected media content during a meeting. It involves a display node managing a primary display, and receiving content from a peripheral device. This peripheral device connects to a user's computer (processing device) and runs a temporary program to capture the computer's screen content ("screen scrape"). The program is designed to leave no trace after it finishes running (zero footprint). The user initiates the transfer of their screen content to the peripheral device, which then sends it to the display node for presentation on the main display. Audio data is captured through a virtual sound card interface on the peripheral device, using generic, pre-installed drivers on the user's computer. The captured audio and video are time-stamped for synchronization.
• Claim 11 (Electronic meeting tool system): This claim outlines an electronic meeting tool system including a display node connected to a main display, and at least one peripheral connection unit. The display node receives user-selected media content and manages its display. The peripheral unit connects to a user's processing device (e.g., laptop), which has its own display, memory, and operating system. The peripheral unit contains a program that, when run on the processing device, captures screen content and transmits it to the display node. This program is "zero footprint," meaning it leaves no permanent installation or configuration changes on the processing device. The system also captures audio data via a virtual sound card interface on the peripheral device using generic audio drivers, with audio and video streams being synchronized via time stamps.
• Claim 13 (Peripheral device): This claim describes a peripheral device designed to provide communication connectivity for a processing device (e.g., computer). The peripheral device contains memory storing executable software code. This code sets up communication using generic, pre-installed drivers on the processing device, connects the processing device to a network via the peripheral device's transceiver, and routes screen-scraped data between the processing device and the network. A key feature is that the software uses the generic communication protocol to transfer the screen-scraped data. The peripheral device also incorporates a virtual sound card interface to capture audio data using generic sound drivers, and the audio and video capturing processes are synchronized using time stamps.

Proceedings overview

One Inter Partes Review (IPR) proceeding has been filed against US Patent 10,762,002, which has reached a Final Written Decision. This proceeding resulted in the invalidation of several claims, significantly narrowing the patent's scope. This gives a defendant a strong defensive posture, as any infringement theories relying on the invalidated claims are no longer viable.

IPR2024-01436 — Yealink (USA) Network Technology Co., Ltd. et al. v. Barco N.V.

• Type: Inter Partes Review
• Filed: 2024-09-16
• Status: Final Written Decision
• Judge panel: Judge Stephen C. Siu, Judge Brian D. Green, and Judge Jennifer S. Meyer.
• Petition grounds: The petition challenged claims 1-20 of U.S. Patent No. 10,762,002 under 35 U.S.C. § 102 and § 103, relying on various combinations of prior art references including U.S. Patent Publication No. 2009/0198839 (Leibovich), U.S. Patent Publication No. 2011/0115689 (Leppanen), U.S. Patent Publication No. 2007/0233816 (Rao), U.S. Patent Publication No. 2007/0055743 (Chitrapu), and others.
• Institution decision: Instituted on 2025-03-20. The Board found that Petitioner demonstrated a reasonable likelihood of prevailing with respect to claims 1-20 over various combinations of prior art.
• Final Written Decision (issued 2026-03-19): Claims 1-20 of U.S. Patent No. 10,762,002 were found unpatentable. The panel determined that claims 1-20 were unpatentable under 35 U.S.C. § 103 as obvious over various combinations of prior art, including Leibovich, Leppanen, and Rao, among others. For instance, the Board found that "Petitioner has shown by a preponderance of the evidence that claims 1–20 are unpatentable as obvious."
• Settlement / termination: Not indicated in the available public records as terminated by settlement. The proceeding concluded with a Final Written Decision.
• Appeal: No Federal Circuit appeal has been docketed as of the current date in relation to this IPR.
• Defensive value: All claims (1-20) of US10762002 have been canceled by a Final Written Decision in IPR2024-01436. Any assertion of this patent today, particularly if it relies on these claims, is significantly weakened and potentially frivolous.

Strategic summary

All twenty claims (claims 1-20) of US10762002 are now CANCELED as a result of the Final Written Decision in IPR2024-01436. There are no remaining sustained or untested claims in this patent, as all claims challenged were found unpatentable.

The estoppel landscape is now very favorable for defendants. Under 35 U.S.C. § 315(e)(2), the petitioner, Yealink (USA) Network Technology Co., Ltd. et al., and their privies, are estopped from asserting in a civil action or another USPTO proceeding that claims 1-20 are invalid on any ground that they raised or reasonably could have raised in IPR2024-01436. However, for other defendants, all claims of the patent have been invalidated, meaning the patent can no longer be asserted against them for these claims.

There are no apparent pattern signals of multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner beyond this single IPR. The fact that Unified Patents is involved as a petitioner indicates a defensive aggregator's activity, which often targets patents being asserted in litigation to benefit its members.

Recommended next steps

As a defendant, given that claims 1-20 of US10762002 have been found unpatentable in IPR2024-01436, you should explicitly refer to the Final Written Decision in any response to assertion. This FWD effectively negates the patent's enforceability for all its claims.

You can access the full details of the Final Written Decision on the Unified Patents portal: https://portal.unifiedpatents.com/ptab/case/IPR2024-01436.

Specifically, the disposition states: "For the foregoing reasons, we determine that claims 1–20 of U.S. Patent No. 10,762,002 are unpatentable." This outright cancellation of all claims means that if a demand letter or complaint cites claims 1-20, the asserted patent claims are legally invalid, rendering the assertion baseless.

There are no other active PTAB proceedings pending for this patent. The lack of further appeals to the Federal Circuit suggests that the Patent Owner has either accepted the Board's decision or is still evaluating options, but the current status is that all claims are canceled.

  • Claims 9-12 and 21-24: If the wireless USB solution also handled audio transmission via generic drivers, these claims related to audio capture and synchronization could also be implicated. A key distinction for US10762002, as stated in its description, is its reliance on pre-installed generic drivers without requiring special, proprietary drivers, which might not be fully met by this prior art.

6. US Patent Application Publication 2002/0196378 A1

• Full Citation: US 2002/0196378 A1, System and method for enabling a remote presentation, to Slobodin, David; Smith, Robert A., and assigned to Avistar Systems Corporation.
• Publication/Filing Date: Filed on 2001-05-30, published on 2002-12-26.
• Brief Description (from US10762002): "Screen scraping for presentations is described in US2002/0196378 to Slobodin et al." This patent directly addresses the technique of screen scraping for presentation purposes.
• Potentially Anticipates (35 U.S.C. § 102): This patent directly anticipates the "screen scraping" element of US10762002.
  • Claim 1(e): "wherein the executable software code is adapted to obtain the user selected arbitrary media content by screen scraping content of the second display of the host processing device."
  • Claim 13(e): The corresponding system claim for obtaining content via screen scraping.
    The novelty of US10762002 in this context would likely reside in the combination of screen scraping with the specific peripheral device characteristics (e.g., portable, zero-footprint software, generic drivers, physical form factor, and integrated audio capture/synchronization) within a meeting tool.

The patent US10762002 describes an electronic meeting tool and method for communicating arbitrary media content, including audio, from multiple users to a central display. The invention focuses on a peripheral device that leverages pre-installed generic drivers on a processing device, runs a "zero footprint" screen-scraping application, and captures audio via a virtual sound card interface using generic USB audio drivers, with audio/video synchronization. The goal is to provide an easy-to-use, scalable, and secure solution for collaborative meetings, addressing issues like complex networking, firewall problems, and diverse audio hardware.

Under 35 U.S.C. § 103, an invention is obvious 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."

Here are combinations of prior art references that would render the claims of US10762002 obvious, along with the motivation for a person having ordinary skill in the art (POSITA) to combine them:

Combination 1: US2002/0196378 (Slobodin et al.) + US 2011/0115689 + General Knowledge of Portable Applications and Plug-and-Play USB Devices

References:

• US2002/0196378 to Slobodin et al.: This reference explicitly describes "screen scraping for presentations" [cite: "Screen scraping for presentations is described in US2002/0196378 to Slobodin et al which is included herein by reference."]. This addresses the core method of capturing display content.
• US 2011/0115689: This patent discloses a "USB solution for wireless connection to a projector" [cite: "US 2011/0115689 discloses a similar USB solution for wireless connection to a projector."]. This teaches the use of a USB interface to wirelessly connect a computer to a display device (projector).
• General Knowledge of Portable Applications and Plug-and-Play USB Devices: The US10762002 patent itself defines a "portable application" as a program designed to run without installation and leave a "zero footprint" on the target machine [cite: "a “portable application” (portable app), sometimes also called standalone, is a computer software program designed to run without installation on the target machine."]. It also defines "Plug and play" as facilitating hardware discovery without physical configuration or user intervention, citing USB devices as an example of auto-configuring devices [cite: "Plug and play is a term used to describe the characteristic of a computer bus, or device specification, which facilitates the discovery of a hardware component in a system, without the need for physical device configuration, or user intervention in resolving resource conflicts.", "An example of auto-configuring devices USB devices."]. This indicates that the concepts of portable applications and plug-and-play USB devices, leveraging generic drivers (like mass storage device drivers or human interface device (HID) drivers), were well-known in the art.

Motivation for Combination:
A POSITA, confronted with the "cumbersome process" and "wasted valuable meeting time" associated with traditional cable-based projector connections (Method 1) [cite: "This is not only not scalable but also can be and often is quite a cumbersome process that typically wastes valuable meeting time and takes the dynamism out of the meeting."], and the challenges of network configurations, passwords, and firewalls in LAN-based solutions (Method 2) [cite: "If the connection is made to a corporate LAN there is a danger of virus, malware or spyware transfer in either direction, there is danger of copying of confidential information, and there is the difficulty of making the connection, e.g. entry of a user code and password, as well the administration of such passwords and user codes."], would be motivated to seek a simpler, more user-friendly, and secure presentation system.

• Combining US2002/0196378 with US 2011/0115689: A POSITA would recognize that to achieve a wireless connection for displaying a computer's content on a projector via USB (as taught by US 2011/0115689), efficiently capturing the display content is necessary. Screen scraping, as disclosed in US2002/0196378, provides a direct and effective method for this capture, overcoming the "use of many different video adapters" and "cable length" problems of Method 1 [cite: "The use of many different video adapters, such as VGA, DVI, DP, HDMI . . . . Reach depends on cable length: too long leaves a tangled cable “salad” in the meeting room, too short reduces flexibility, often necessitating people to move around in the meeting room when they want to present something. Cable connection is either point to point or requires tedious and extensive cabling and the use of complex and expensive video switches."].
• Integrating Portable Applications and Plug-and-Play USB: To further simplify the user experience and address security concerns (viruses, malware, confidential information copying, firewalls) [cite: "If the connection is made to a corporate LAN there is a danger of virus, malware or spyware transfer in either direction, there is danger of copying of confidential information, and there is the difficulty of making the connection, e.g. entry of a user code and password, as well the administration of such passwords and user codes.", "Typical problems can occur with firewalls."], a POSITA would be motivated to leverage a plug-and-play USB peripheral device that contains and launches a portable application. This portable application would perform the screen scraping and transmit the content wirelessly via the peripheral, utilizing generic, pre-installed drivers (e.g., as a mass storage device to launch the application, and possibly as an HID for user input). This approach avoids the need for software installation, administrator rights, and direct interaction with the host PC's potentially incompatible network settings or firewalls for the presentation data stream, thus achieving the "zero footprint" and ease-of-use goals.

Combination 2: Combination 1 + General Knowledge of Generic USB Audio Devices (UAC1/UAC2) and Audio-Video Synchronization Techniques

References:

• Combination 1 (US2002/0196378 + US 2011/0115689 + General Knowledge of Portable Applications and Plug-and-Play USB Devices): Provides a wireless, zero-footprint screen-sharing solution via a USB peripheral.
• General Knowledge of Generic USB Audio Devices (UAC1/UAC2): The US10762002 patent states, "on every PC-like platform, there is standard built-in support for a USB audio device" and "a generic sound driver such as a USB sound driver is required which is generally standard on any modern processing devices such as a PC (UAC1 or UAC2)" [cite: "For example, on every PC-like platform, there is standard built-in support for a USB audio device.", "a generic sound driver such as a USB sound driver is required which is generally standard on any modern processing devices such as a PC (UAC1 or UAC2)."]. This acknowledges that the capability to handle USB audio devices using generic, pre-installed drivers (like Universal Audio Class 1 or 2) is a standard feature on modern processing devices.
• General Knowledge of Audio-Video Synchronization: The patent identifies "the need for synchronization of the captured audio with the captured video to provide lip synchronization" as a problem [cite: "the present invention addresses the problems caused by the many different audio cards in use for commercial PC's, a lack of a standard way for capturing audio that works on all PC platforms (Windows, Mac, Linux, Android) and the need for synchronization of the captured audio with the captured video to provide lip synchronization."]. Time-stamping individual audio and video packets/frames to maintain synchronization (lip sync) at the receiving end is a well-established technique in real-time multimedia streaming and processing.

Motivation for Combination:
A POSITA, having developed a wireless screen-sharing solution (as in Combination 1) and recognizing the "Lack of standards for audio, Need to install proprietary drivers for audio Large number of different, non-standardised sound cards in use" [cite: "Lack of standards for audio Need to install proprietary drivers for audio Large number of different, non-standardised sound cards in use"] as significant problems in meetings, would be motivated to integrate audio capture seamlessly into the existing system.

• Integrating Generic USB Audio: Given the ubiquitous support for generic USB audio devices and drivers (UAC1/UAC2), it would be an obvious design choice for a POSITA to configure the peripheral device (already connected via USB for video sharing) to also act as a "virtual sound card" or USB audio device. This would allow the host PC's audio output to be routed through the peripheral device using existing generic drivers, thereby eliminating the need for proprietary audio drivers and addressing the compatibility issues across different sound cards and operating systems. The peripheral device could be implemented as a composite USB device to present multiple functionalities (e.g., mass storage, HID, and audio device) through a single physical connection.
• Implementing Audio-Video Synchronization: Once both video (screen-scraped) and audio (captured via the virtual USB sound card) are being processed and streamed by the same peripheral device, a POSITA would be motivated to employ standard audio-video synchronization techniques, such as time-stamping, to ensure "lip synchronization" at the central display. This is a fundamental requirement for any effective multimedia presentation system.

Conclusion

The elements of US10762002, specifically the wireless transmission of screen-scraped arbitrary media content (both video and audio) via a plug-and-play, zero-footprint USB peripheral that utilizes generic drivers, and the synchronization of audio and video, appear to be combinations of known technologies and readily apparent design choices to a person having ordinary skill in the art. The motivation to combine these elements stems from persistent, well-documented problems in meeting efficiency, ease of use, security, and compatibility that existed in the prior art. Therefore, the claimed invention would likely have been obvious under 35 U.S.C. § 103.
