Title: Signal processing apparatus and methods
Assignee: CONTENTNEXUS LLC
Inventors: John Christopher Harvey, James William Cuddihy
Filing Date: June 2, 1995
Issue Date: December 31, 2019
Abstract:
The invention relates to an integrated system for programming communication that encompasses computer processing, television, radio, and other electronic communications. It includes methods and apparatus for automating the handling, recording, and retransmitting of various forms of programming. The system also has capabilities for regulating, metering, and monitoring the availability and usage of such programming. A key feature is the ability to embed signals within the programming to control and personalize the content for individual subscribers. This allows for features like user-specific information overlays on television broadcasts and automated control of various subscriber station apparatus. The system is designed to be flexible, allowing for variations in individual station equipment and the ability to update and modify the system through transmitted software.
Plain-Language Overview of Independent Claims:
This patent contains numerous independent claims, each defining a different aspect of the invention. Below is a simplified explanation of each independent claim. It is important to note that the legal scope of a patent claim is determined by its exact language, and this summary is for informational purposes only.
Claim 1: This claim describes a method for generating and transmitting a signal. The method involves creating a first signal that includes both programming content and an instruction. This first signal is then transmitted to a receiving station. At the receiving station, a second signal containing station-specific information is generated. The instruction from the first signal is then used to combine the station-specific information from the second signal with the programming content from the first signal, creating a personalized output.
Claim 26: This claim outlines a method for creating a television signal with personalized information. It involves generating a standard television signal that includes both video programming and an embedded instruction. This signal is sent to a subscriber's television equipment. The subscriber's equipment, in response to the embedded instruction, generates a video graphic containing information specific to that subscriber. This graphic is then overlaid onto the original video programming, and the combined video is displayed on the subscriber's television.
Claim 49: This claim focuses on a method for processing a television signal at a subscriber's location. The subscriber's equipment receives a television signal that has an instruction embedded within its non-viewable portion (the vertical blanking interval). The equipment is pre-programmed with a set of operating instructions. The received embedded instruction is then used to select a specific operating instruction from the pre-programmed set, and the equipment operates according to that selected instruction.
Claim 63: This claim details a method for controlling a subscriber's equipment using an incoming television signal. The television signal contains an embedded instruction. The subscriber's equipment receives this signal and, in response to the instruction, generates a control signal. This control signal is then used to operate an external device that is separate from the television receiver itself.
Claim 80: This claim describes a method for creating a personalized television program for a subscriber. A television signal is received that includes both programming content and an instruction. Separately, information specific to the subscriber is received from a different source. The instruction in the television signal is then used to create a new, "hybrid" signal by combining the programming content with the subscriber-specific information. This hybrid signal is then used to create the personalized television program.
Claim 95: This claim outlines a method for creating a combined media presentation. It involves receiving a television program and, at the same time, operating a computer program at the subscriber's location. An instruction embedded in the television program causes the computer to generate a video message. The system then combines this computer-generated video message with the television program to create the final presentation.
Claim 102: This claim describes a method for displaying personalized information on a television screen. A television signal is received that contains both video programming and an instruction. At the subscriber's station, a second signal is generated that contains information unique to that subscriber. The instruction from the television signal is then used to combine the subscriber-specific information with the video programming, and the resulting combined video is shown on the television.
Claim 112: This claim details a method for controlling a television receiver. The receiver is tuned to a specific channel. A television signal is received on that channel which contains an instruction. In response to this instruction, the receiver automatically performs a specific operation.
Claim 120: This claim describes a method for creating a personalized display at a subscriber's station. A broadcast signal containing both programming and an instruction is received. A separate set of information specific to the subscriber is stored at their station. The instruction in the broadcast signal is used to process this subscriber-specific information. The result of this processing is then combined with the broadcast programming to create the final display.
Based on a search of the CAFC dockets for 2026, there is no publicly available information indicating that US Patent 10,523,350 is currently involved in any litigation before the Court of Appeals for the Federal Circuit. However, this does not preclude the possibility of litigation at the district court level or other legal proceedings.

Litigation summary
Past and pending lawsuits — plaintiffs, defendants, jurisdictions, outcomes, and notable rulings.
As a patent analyst, I have conducted a thorough search for litigation involving US Patent 10,523,350. As of today, May 1, 2026, there is one known case involving this patent.
It is important to note that the original assignee, Personalized Media Communications, LLC (PMC), has been involved in other significant patent litigation, including a notable case against Apple involving a different patent (U.S. Patent No. 8,191,091). In that case, a jury awarded PMC $308.5 million, but the patent was later found unenforceable due to prosecution laches. This history of assertive patent enforcement by the original assignee may be relevant context for any litigation involving patents now held by CONTENTNEXUS LLC.
Here are the details of the known litigation for US Patent 10,523,350:
ContentNexus LLC v. Red Bull GMBH
- Plaintiff(s): ContentNexus LLC
- Defendant(s): Red Bull GMBH
- Jurisdiction: United States District Court for the Eastern District of Texas
- Case Number: 2:26-cv-00323
- Filing Date: April 22, 2026
- Status: This case was recently filed and is currently in its early stages. No significant developments or outcomes have been reported. This case appears to be part of a broader litigation campaign by ContentNexus LLC, which filed several lawsuits against different companies on the same day, asserting various patents.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Proceedings overview
As of May 31, 2026, there are no publicly available records from the USPTO Open Data Portal or general web searches indicating any AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method review) against US Patent 10,523,350. Therefore, all claims of the patent remain untested by PTAB challenges.
Strategic summary
Currently, all claims of US 10,523,350 are UNTESTED by AIA trial proceedings. This means that a potential defendant has full flexibility in bringing any available prior art grounds, including those that were or could have been raised in a PTAB petition, without facing estoppel under 35 U.S.C. § 315(e)(2). The absence of PTAB activity can be a signal, as well-asserted patents often become targets for IPRs. Given the recent litigation filing by ContentNexus LLC in April 2026, it is possible that PTAB petitions may be filed in the near future.
Recommended next steps
If facing assertion of US 10,523,350, a potential defendant should consider initiating an AIA trial proceeding (e.g., an Inter Partes Review) to challenge the patentability of the asserted claims. The prior art analysis provided previously, particularly the U.S. Patent No. 4,025,851 to Haselwood et al., suggests strong grounds for challenging claims related to embedding instructions in the vertical blanking interval to trigger operations (e.g., Claim 49 and Claim 112). A detailed analysis of the patent claims against known and newly discovered prior art would be crucial to identify the strongest grounds for a petition.

This strongly suggests the transfer was arranged to enable assertion.
Bankruptcy fire-sale — not present. No indication of bankruptcy in the assignment records or general patent information.
Privateering — unclear. While Personalized Media Communications, L.L.C. was the original assignee and ContentNexus LLC is now asserting the patent, there is no explicit evidence from SEC filings or other public coverage to definitively establish a privateering arrangement where an operating company transfers to an NPE to assert on its behalf against competitors.
Defensive aggregator (anti-NPE) — not present. The chain does not end at a known defensive aggregator.
Verdict
NPE — high confidence
This verdict is based on multiple strong signals: the presence of a known asserter (Personalized Media Communications, L.L.C.) as the original assignee, the transfer to another entity (CONTENTNEXUS LLC) which has immediately initiated litigation, and the clear pre-litigation transfer on 2025-06-09 (Reel 063063/0187) occurring less than a year before the first known infringement suit (2:26-cv-00323) was filed. The current assignee, CONTENTNEXUS LLC, also exhibits characteristics of a shell entity, further supporting this conclusion.

Prior Art Analysis for U.S. Patent No. 10,523,350
As a senior U.S. patent analyst, I have reviewed the prior art cited during the prosecution of U.S. Patent No. 10,523,350. Below is an analysis of each reference, detailing its content and its potential relevance to the claims of the '350 patent under 35 U.S.C. § 102 (Anticipation).
This analysis is based on the "References Cited" section of the issued patent and my interpretation of the claims. The '350 patent has a very early priority date of November 3, 1981, based on its parent application, US06/317,510. This early date is critical, as any prior art must have been published before this date to be considered anticipatory.
Cited U.S. Patent Documents
U.S. Patent No. 3,845,391: "Broadcast signal identification system" (Crosby)
- Publication Date: October 29, 1974
- Filing Date: June 18, 1973
- Brief Description: The Crosby patent discloses a system for identifying broadcast programs by embedding an inaudible identification code within the audio signal of the program. A monitoring device at a remote location can detect this code to verify program transmission. The primary purpose is for broadcast monitoring and verification for advertisers.
- Potential Anticipation Analysis: This reference teaches embedding an identification signal within a broadcast.
- Claim 49: Potentially anticipates the concept of receiving a signal with an embedded instruction. Crosby's "identification code" could be interpreted as a form of "instruction" that directs the monitoring equipment to perform an operation (i.e., record the presence of the code).
- Claim 112: Could be argued to anticipate this claim if the "identification code" is considered an "instruction" and the monitoring device is considered a "television receiver" performing an "operation" (logging the broadcast). However, the '350 patent's claims are generally directed toward personalizing content at the subscriber end, whereas Crosby is focused on broadcast verification.
U.S. Patent No. 4,025,851: "Automatic monitoring of television programs" (Haselwood et al.)
- Publication Date: May 24, 1977
- Filing Date: October 2, 1975
- Brief Description: Haselwood describes a system for automatically monitoring television programs to determine audience viewing habits. It involves embedding an identification code in the video signal (specifically, in the vertical blanking interval, or VBI) that is imperceptible to the viewer. A special monitoring unit at the television receiver detects this code and records which channel is being watched and when.
- Potential Anticipation Analysis: This is a significant prior art reference as it explicitly discloses embedding data in the VBI of a television signal to trigger an operation in a receiving unit.
- Claim 49: This claim appears to be strongly anticipated by Haselwood. Haselwood teaches receiving a television signal with an instruction embedded in the vertical blanking interval (a non-viewable portion) that causes the receiver-side equipment to operate according to pre-programmed instructions (i.e., to record viewing data).
- Claim 112: Haselwood also teaches a receiver being tuned to a channel, receiving an instruction (the identification code), and automatically performing an operation (recording the event).
- Claims 1, 26, 80, 95, 102, 120: While Haselwood discloses the core mechanism of embedding instructions, it does not appear to describe the second key step in these claims: combining the broadcast programming with station-specific or user-specific information to create a personalized output. Haselwood's system is for monitoring, not for augmenting the displayed content with local data.
U.S. Patent No. 4,264,925: "Multi-channel television program simulation system" (Freeman et al.)
- Publication Date: April 28, 1981
- Filing Date: July 26, 1978
- Brief Description: Freeman discloses a system that allows a user to switch between different but related video streams broadcast simultaneously on multiple channels. For example, a user watching a sporting event could switch between different camera angles. The system provides a way for a user to interact with the broadcast to select from pre-determined, centrally-broadcast options.
- Potential Anticipation Analysis: This reference deals with user choice but not with the automatic combination of broadcast data with locally-stored, user-specific data.
- No direct anticipation: Freeman's system relies on the user making a manual selection between multiple, fully-formed broadcast streams. It does not teach using an embedded instruction to automatically combine a primary broadcast with locally-generated, user-specific information as required by claims like 1, 26, 80, and 102.
U.S. Patent No. 4,337,480: "Dynamic interconnection system for television peripheral units" (Bourassin et al.)
- Publication Date: June 29, 1982
- Filing Date: February 28, 1980
- Brief Description: Bourassin describes a centralized switching system for managing various television peripherals (VCR, video game console, etc.). It allows for features like picture-in-picture, where a secondary image from one peripheral can be superimposed on the main image from another. The control is local to the user.
- Potential Anticipation Analysis: The '480 patent was filed before the '350 patent's priority date but published after. Under the pre-AIA "first-to-invent" system that applies here, it could be prior art if the invention date of Bourassin predates that of the '350 patent. Assuming it is valid prior art for the sake of analysis:
- Claims 26, 95, 102: Bourassin teaches combining two video sources into a single display. However, it does not teach that this combination is triggered by an instruction embedded in the broadcast signal. The user manually controls the combination via the interconnection system. Therefore, it does not anticipate these claims, which require the combination to be initiated by a broadcast instruction.
U.S. Patent No. 4,381,522: "Interactive television program and distribution system" (Lambert)
- Publication Date: April 26, 1983
- Filing Date: October 24, 1980
- Brief Description: Lambert discloses an interactive cable TV system where a central computer generates a program schedule based on viewer requests sent over telephone lines. The system then automatically plays and transmits pre-recorded programs according to this schedule.
- Potential Anticipation Analysis: Like Bourassin, this patent was filed before the '350 priority date but published after. Assuming it qualifies as prior art:
- No direct anticipation: The control mechanism in Lambert is a two-way system where users "pull" content by making requests. The '350 patent describes a one-way broadcast system that "pushes" instructions to the user's equipment to act on local information. Lambert's system does not involve embedding instructions in the broadcast signal to trigger a combination with user-specific data at the receiver.
U.S. Patent No. 4,547,804: "Multiplex television monitoring system and method" (Greenberg)
- Publication Date: October 15, 1985
- Filing Date: November 22, 1982
- Brief Description: Greenberg describes a system for monitoring multiple television channels by sequentially tuning to them and identifying embedded codes. It also includes the capability to monitor the audio and visual quality of the broadcast.
- Potential Anticipation Analysis: This patent was filed after the '350 patent's priority date and is therefore not prior art under 35 U.S.C. § 102. It was likely cited by the examiner to show the state of the art during prosecution.
Summary of Prior Art Analysis
The most relevant prior art cited against US 10,523,350 is U.S. Patent No. 4,025,851 to Haselwood et al. This reference clearly discloses the foundational concept of embedding machine-readable instruction codes into a non-viewable portion of a television signal (the VBI) to cause a receiver-side apparatus to perform a pre-programmed function automatically. This appears to anticipate the core ideas of independent claims 49 and 112.
However, Haselwood's system is for monitoring and data collection, not for creating a personalized media experience. It does not teach the key inventive step present in the other independent claims (1, 26, 63, 80, 95, 102, 120), which is the use of the embedded instruction to combine the broadcast program with locally-stored or locally-generated user-specific information to create a hybrid, personalized output for the user. The distinction lies in modifying the presented content for the user, rather than simply monitoring the user's activity. The other references, while related to interactive or enhanced television, also fail to disclose this specific combination of a broadcast-embedded instruction acting on local data for content personalization.

Obviousness Analysis for U.S. Patent No. 10,523,350 under 35 U.S.C. § 103
This analysis examines whether the claims of U.S. Patent No. 10,523,350 (the '350 patent) would have been obvious to a person having ordinary skill in the art (PHOSITA) at the time of its priority date, November 3, 1981. The analysis considers combinations of the cited prior art references and the motivations a PHOSITA would have had to combine them.
Independent Claims 49 and 112: Basic Control by Embedded Instruction
- Claim 49: A method for processing a television signal at a subscriber's location, where an instruction embedded in the non-viewable portion of a television signal causes the equipment, pre-programmed with operating instructions, to select and operate according to a specific instruction.
- Claim 112: A method for controlling a television receiver, where the receiver, tuned to a channel, receives a television signal with an embedded instruction and automatically performs a specific operation in response.
Combination and Rationale:
These claims appear to be rendered obvious by U.S. Patent No. 4,025,851 to Haselwood et al. (Haselwood) alone. Haselwood discloses a system for automatically monitoring television programs by embedding an identification code in the vertical blanking interval (VBI), a non-viewable portion, of a television signal. A monitoring unit at the receiver detects this code and records viewing data.
A PHOSITA would recognize that Haselwood's "identification code" functions as an "instruction" embedded in a non-viewable portion of the signal. The monitoring unit is "pre-programmed with a set of operating instructions" to detect and react to this code (e.g., to log viewing activity). Therefore, the system "selects a specific operating instruction from said set" (the instruction to record viewing data) and "operates according to that selected instruction" (Claim 49). Similarly, Haselwood describes a receiver automatically performing an operation (recording which channel is being watched) in response to the embedded code (Claim 112). The primary distinction in the '350 patent's claims, if any, would be the nature of the instruction and the type of operation, but the fundamental mechanism of an embedded, non-viewable instruction triggering an automatic, pre-programmed operation at the receiver is explicitly taught by Haselwood.
Independent Claim 63: Controlling an External Device
- Claim 63: A method for controlling a subscriber's equipment where a television signal with an embedded instruction is received, and in response, a control signal is generated to operate an external device separate from the television receiver.
Combination and Rationale:
This claim appears obvious by combining Haselwood with general knowledge of controlling external devices.
A PHOSITA in 1981, familiar with Haselwood's system for triggering receiver-side operations via embedded signals, would have been motivated to apply this proven mechanism to control other devices. Given the common practice of connecting various external devices (e.g., VCRs, stereo systems) to television receivers, it would have been an obvious extension to use the embedded instruction, rather than manual input, to automate the control of such devices. For example, if an embedded signal could instruct a monitoring unit to log viewing (Haselwood), a PHOSITA would foreseeably adapt this to instruct a VCR to start recording, or a stereo system to change volume, in synchronization with broadcast content. The patent itself notes a deficiency in prior art VCRs for lacking capacity for "controlling the connection or actuation or tuning of external apparatus" based on embedded signals, implicitly suggesting this was a desirable and logical next step for automation.
Independent Claims 1, 26, 80, 95, 102, and 120: Personalized Content Generation and Overlay
- Claim 1: Method for generating and transmitting a signal including programming content and an instruction, wherein a second signal containing station-specific information is generated at a receiving station, and the instruction causes the combination of station-specific information with the programming content.
- Claim 26: Method for creating a television signal with personalized information, involving a standard television signal with video programming and an embedded instruction, causing subscriber equipment to generate a video graphic with subscriber-specific information and overlay it onto the video programming for display.
- Claim 80: Method for creating a personalized television program, where a television signal with programming content and an instruction is received, separate subscriber-specific information is also received, and the instruction creates a "hybrid" signal by combining the programming content with the subscriber-specific information.
- Claim 95: Method for creating a combined media presentation, involving receiving a television program, simultaneously operating a computer program at the subscriber's location, where an instruction in the television program causes the computer to generate a video message, and combining this message with the television program.
- Claim 102: Method for displaying personalized information, where a television signal with video programming and an instruction is received, a second signal with subscriber-specific information is generated, and the instruction combines the subscriber-specific information with the video programming for display.
- Claim 120: Method for creating a personalized display, where a broadcast signal with programming and an instruction is received, stored subscriber-specific information is processed according to the instruction, and the result is combined with the broadcast programming.
Combination and Rationale:
These claims, which represent the core personalization aspect of the '350 patent, would likely have been obvious by combining Haselwood, U.S. Patent No. 4,337,480 to Bourassin et al. (Bourassin), and general knowledge of microcomputers and graphics display technologies around 1981.
- Haselwood provides the trigger: Haselwood clearly teaches embedding machine-readable instructions in the VBI of a broadcast television signal to trigger an automatic operation at the receiver. A PHOSITA would readily understand that this mechanism could be used to initiate actions beyond simple monitoring.
- Bourassin provides the overlay mechanism: Bourassin discloses an interconnection system for television peripheral units that enables features like "image-within-image," where a secondary image from a peripheral unit can be superimposed upon a primary image on a television display. This demonstrates the technical feasibility of combining and overlaying different video sources at a subscriber's location.
- General knowledge of microcomputers and data processing (circa 1981): By 1981, personal computers (microcomputers) were available, capable of storing local data (e.g., on floppy disks, as described in the '350 patent for a stock portfolio), running programs, and generating graphics. The '350 patent itself refers to "graphic overlay techniques, well known in the art," indicating that the concept of overlaying computer-generated graphics onto video signals was understood.
Motivation for Combination:
A PHOSITA, aiming to enhance the utility and interactivity of broadcast television for individual subscribers, would have been highly motivated to combine these known elements. Seeing Haselwood's ability to automate responses to embedded broadcast signals, and Bourassin's demonstration of video overlay capabilities, the motivation would be to move beyond simple monitoring or manual selection to offer dynamic, personalized content.
Specifically, a PHOSITA would consider using Haselwood's embedded instruction mechanism to automatically:
- Trigger a local computer program: Instead of just logging an event, the instruction could "command microcomputer, 205, (and all other subscriber station microcomputers simultaneously) to interrupt the operation of its central processor unit..." and then "load... and run the information of a particular set of instructions" received from the broadcast.
- Process locally-stored, user-specific data: The local computer could then access and process data unique to that subscriber (e.g., a stock portfolio stored on a disk, as described in the '350 patent), generating a personalized graphic or message.
- Overlay the personalized output onto the live broadcast: Leveraging techniques similar to Bourassin's image superposition, or other known graphics overlay hardware and software (as the '350 patent refers to "graphic overlay techniques, well known in the art"), the computer-generated, user-specific graphic could be overlaid onto the incoming television programming. The "GRAPHICS ON" command described in the '350 patent as being executed by the microcomputer to perform this overlay illustrates this precise integration.
The overall motivation would be to create a more engaging and valuable television experience by intelligently integrating local, personalized information with mass broadcast content, without requiring explicit manual intervention by the user for each personalization event. This would be a natural progression from basic broadcast monitoring and local video switching technologies.
