Intelligent Protection Management Corp v. Cisco Technology Inc
1. Case Identification
- Case #: IPR2025-01588
- Patent #: 8,830,293
- Filed: October 6, 2025
- Petitioner(s): Intelligent Protection Management Corp.
- Patent Owner(s): Cisco Technology, Inc.
- Challenged Claims: 1-20
2. Patent Overview
- Title: Video Superposition for Continuous Presence
- Brief Description: The ’293 patent describes methods and systems for combining multiple real-time video streams into a single display for videoconferencing. The technology aims to create the appearance that all participants are in the same room by scaling subject images, removing their original backgrounds, and superimposing them in an anterior-posterior arrangement (e.g., like stadium seating) within a combined video frame.
3. Grounds for Unpatentability
Ground 1: Obviousness over Tysso - Claims 1-20 are obvious over Tysso.
- Prior Art Relied Upon: Tysso (Patent 8,345,082).
- Core Argument for this Ground:
- Prior Art Mapping: Petitioner argued Tysso discloses all limitations of the challenged claims. Tysso teaches a "dynamic layering" videoconferencing system that receives video streams from multiple endpoints and processes them to make participants appear to be in the same room. Specifically, Tysso discloses receiving video streams with subject and background images, extracting participant images from their backgrounds, scaling the images to a uniform size, and merging them in an overlapping, layered fashion on a single monitor. Petitioner contended this layering inherently creates an "anterior" and "posterior" arrangement as required by claim 1.
- Motivation to Combine (for §103 grounds): As a single-reference ground, Petitioner argued that Tysso alone renders the claims obvious because it teaches a complete system that performs the claimed steps. For any minor variations, Petitioner asserted that implementing Tysso’s system would have involved predictable design choices, such as the order of scaling and background removal, which would have been obvious to a Person of Ordinary Skill in the Art (POSITA).
- Expectation of Success (for §103 grounds): A POSITA would have had a high expectation of success in implementing the claimed method using Tysso’s teachings, as Tysso's primary purpose is to achieve the same visual effect as the ’293 patent.
Ground 2: Obviousness over Tysso in view of GIMP - Claims 1-20 are obvious over Tysso in view of GIMP.
- Prior Art Relied Upon: Tysso (Patent 8,345,082) and GIMP (User Manual for GNU Image Manipulation Program, dated May 1, 2007).
- Core Argument for this Ground:
- Prior Art Mapping: This ground built upon the disclosures of Tysso, supplementing it with the teachings of GIMP, which Petitioner presented as analogous art for image processing. GIMP explicitly describes manipulating images using a layer-based system, including tools to scale entire layers (analogous to scaling the entire video frame) or just selections within a layer (analogous to scaling only the subject image). GIMP also teaches making backgrounds transparent to reveal underlying layers (e.g., using a "Color to Alpha" filter), which corresponds to the claimed "removing the background" step. The combination of Tysso’s videoconferencing framework with GIMP’s specific, well-known layer manipulation techniques was argued to teach every element of the claims.
- Motivation to Combine (for §103 grounds): A POSITA, seeking to implement the video composition described in Tysso, would combine it with the fundamental and widely known image manipulation techniques detailed in GIMP. GIMP provided a well-understood toolkit for achieving the layering, scaling, and background removal central to Tysso's system. Using GIMP’s methods to scale an entire video frame as a layer or to extend a background by resizing a layer to fit a larger canvas were presented as obvious and predictable implementation details.
- Expectation of Success (for §103 grounds): A POSITA would have reasonably expected success in applying GIMP's established digital image processing techniques to the video frames in Tysso’s system, as video is essentially a sequence of digital images.
4. Key Claim Construction Positions
- Petitioner argued for an implicit order of operations in claim 1 and related claims. The language "scaling the video frames ... to produce a first sequence of scaled video frames" followed by "removing the background image in the first sequence of scaled video frames" requires that scaling must occur before background removal. Petitioner asserted that even under this construction, which it deems the correct interpretation, the prior art renders the claims obvious because performing scaling before background removal was merely one of a limited number of predictable design choices available to a POSITA.
5. Arguments Regarding Discretionary Denial
- Petitioner asserted that discretionary denial would be unwarranted. It stated its intent to address any discretionary denial factors raised by the Patent Owner, including those under 35 U.S.C. §325(d), in subsequent briefing as instructed by the Board. This position was presented in the context of a co-pending district court litigation involving the ’293 patent.
6. Relief Requested
- Petitioner requests the institution of an inter partes review and the cancellation of claims 1-20 of the ’293 patent as unpatentable under 35 U.S.C. §103.
