II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 4,706,121 - TV Schedule System and Process
- Patent Identification: U.S. Patent No. 4,706,121 (“TV Schedule System and Process”), issued November 10, 1987 (as modified by Reexamination Certificate B1 4,706,121, issued December 14, 1993).
The Invention Explained
- Problem Addressed: The patent identifies the growing difficulty for viewers to navigate an expanding number of television channels using static, printed program guides. It also highlights the complexity and error-prone nature of programming a video cassette recorder (VCR) for unattended recording, a feature many users found too difficult to use effectively (’121 Patent, col. 1:44-2:24).
- The Patented Solution: The invention proposes a system where a television receiver or a connected device electronically receives schedule data. This data is then displayed on the TV screen as an interactive menu-driven guide, allowing a user to browse listings and select programs for immediate viewing or future recording using simple remote-control commands. The system is designed to simplify VCR programming and allow for filtering programs by user-defined criteria, such as theme or time of day (’121 Patent, Abstract; Fig. 3; col. 4:36-60). A block diagram in the patent illustrates the overall system architecture, showing a CPU (110) controlling a programmable TV tuner (132) and a video display generator (136) based on user inputs from a remote control (116) (’121 Patent, Fig. 3; Compl. Ex. 1, p. 10).
- Technical Importance: The technology represented a significant shift in user interface design for television, moving program selection from a passive, paper-based process to an interactive, on-screen experience that integrated viewing and recording functions (’121 Patent, col. 2:5-10).
Key Claims at a Glance
- The complaint does not assert any specific claims, instead alleging infringement of the "’121 patent" generally (Compl. ¶12). For analytical purposes, reexamined independent claim 1 is presented below.
- Reexamined Independent Claim 1: A system for controlling a television receiver, with the following essential elements:
- A data processor.
- A first input for receiving schedule information and a second input for receiving user selections.
- A storage means connected to receive a "reminder calendar list" containing information for programs selected by the data processor.
- A programmable tuner that receives control signals from the data processor to tune to selected programs at the broadcast time.
- The data processor is configured to actuate a program recorder and supply the broadcast signal to it.
- The system is configured to allow the television to receive a different program than the one being recorded.
- The user inputs include a "plurality of user program selection criteria" (e.g., theme, channel) which the data processor can "combine" to present a filtered list of programs.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
The accused instrumentalities are "direct broadcast satellite ('DBS') receivers" and the associated "interactive electronic program guide" that are part of the service offered by Defendant EchoStar (Compl. ¶6).
Functionality and Market Context
- The complaint provides minimal detail on the specific functionality of the accused products. It alleges that EchoStar's DBS service "includes an interactive electronic program guide" (Compl. ¶6). A patent holder would likely allege that this guide allows users to view on-screen listings of television programs and select them for viewing or recording.
- The complaint alleges significant commercial importance, stating that EchoStar has sold its DBS receivers to "over 3.4 million subscribers throughout the United States" (Compl. ¶6).
- The patent depicts a remote control layout with keys for navigating a "Master Guide" (MG) and "Program Guide" (PG), illustrating the type of user interaction central to the invention (’121 Patent, Fig. 5; Compl. Ex. 1, p. 13).
IV. Analysis of Infringement Allegations
The complaint alleges infringement in general terms and does not contain a claim chart or map specific features of the accused products to elements of any particular claim (Compl. ¶12). The following chart summarizes the likely infringement theory for reexamined Claim 1, based on the complaint's general description of the accused instrumentality.
’121 Patent Infringement Allegations

- Identified Points of Contention:
- Scope Questions: The reexamination of the ’121 patent introduced the term "reminder calendar list." A central question will be whether the data structure used by the EchoStar EPG to manage scheduled recordings or viewings constitutes a "reminder calendar list" as required by the amended claim, or if it is functionally and structurally different.
- Technical Questions: Does the accused EchoStar guide "combine" a "plurality of user program selection criteria" as claimed? The infringement case may depend on whether the guide performs a specific logical combination of distinct criteria (e.g., theme and channel) or merely allows for sequential, single-category filtering, which may not meet the claim limitation. The complaint provides no evidence on this point.
V. Key Claim Terms for Construction
The Term: "reminder calendar list"
- Context and Importance: This term was added to Claim 1 during reexamination and is not defined in the original specification. Its construction is critical because it likely represents a key distinction over prior art that enabled the claim to be confirmed. The infringement analysis will likely turn on whether the accused product's list of scheduled recordings meets the definition of this term.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A plaintiff may argue the term should be interpreted broadly to cover any stored list of user-selected future programs. The specification describes a "weekly reminder calendar" function that can be programmed to respond to a series of programs and can set an alarm or start a VCR, suggesting the "list" is a functional collection of scheduled events (’121 Patent, col. 15:19-31).
- Evidence for a Narrower Interpretation: A defendant may argue the term requires a specific data structure or user interface explicitly presented to the user as a "calendar" or "reminder" list, distinct from a simple list of VCR timers. The reexamination certificate amends the specification to refer to the "PG+Schedule Setup" as a "reminder calendar schedule," which a court might see as tying the claim term to that specific embodiment (’121 Patent Reexam. Cert., col. 1:47-2:10; Compl. Ex. 2, p. 38).
The Term: "combine said plurality of user program selection criteria"
- Context and Importance: This phrase defines the required functionality of the program guide's search and filtering capabilities. Whether the accused product infringes will depend on how its filtering mechanism operates compared to the "combining" required by the claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent's objective is to simplify selection from a large volume of programs. Plaintiff may argue that any feature allowing a user to apply more than one filter (e.g., selecting a "theme" and then separately a "prime time" restriction) satisfies the "combining" limitation.
- Evidence for a Narrower Interpretation: The detailed description of the "Master Guide" mode explains how a user can activate filters for prime time, theme, and channel group simultaneously, with a status line showing which are active (’121 Patent, col. 10:45-65, col. 13:20-44). A defendant may argue this implies a requirement for a system that can apply multiple, independent categories of criteria concurrently in a single search operation, not just in sequence.
VI. Other Allegations
- Indirect Infringement: The complaint includes boilerplate allegations of induced and contributory infringement but provides no specific supporting facts, such as references to user manuals or advertisements that would instruct users to infringe (Compl. ¶12).
- Willful Infringement: Plaintiff alleges that EchoStar's infringement has been willful and deliberate, based on alleged "full knowledge of StarSight's rights" (Compl. ¶16). The complaint does not, however, plead any specific facts to support this assertion, such as evidence of pre-suit notification.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope defined by reexamination: Can the term "reminder calendar list," added during reexamination, be construed to read on the functionality for scheduling future recordings in EchoStar's accused program guide, or does the term require a more specific structure and interface that the accused product lacks? The outcome may depend heavily on the prosecution history of the reexamination, which is not in the record.
- A key evidentiary question will be one of functional operation: Given the complaint's lack of technical detail, the case will depend on whether discovery reveals that the accused EchoStar system actually performs the specific "combining" of multiple search criteria as required by Claim 1, or if its filtering mechanism operates in a technically distinct manner.
