Wi LAN Inc v. LG Electronics Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: WI-LAN INC. (Canada)
- Defendant: LG Electronics, Inc. (Korea) and LG Electronics USA., Inc. (Delaware)
- Plaintiff’s Counsel: Menz Bonner & Komar LLP; Townsend and Townsend and Crew LLP
- Case Identification: 1:10-cv-00432, S.D.N.Y., 08/23/2010
- Venue Allegations: Venue is alleged based on Defendants' continuous and systematic business activities in New York and a prior license agreement between the parties that reportedly agreed to venue in the court.
- Core Dispute: Plaintiff alleges that Defendant’s digital television receivers infringe a patent related to dynamically configurable "V-Chip" parental control technology, and further alleges that Defendant fraudulently induced Plaintiff's predecessor into a license agreement for the patent.
- Technical Context: The technology concerns a method for selectively blocking television programming by interpreting content rating data that is embedded in the broadcast signal, a feature whose "flexible" implementation was mandated by the U.S. Federal Communications Commission (FCC) for digital televisions.
- Key Procedural History: The complaint alleges a complex history preceding the litigation. Plaintiff's predecessor and LG entered a license agreement for the patent-in-suit in 2006, following negotiations in which LG allegedly acknowledged the patent's necessity for complying with new FCC "flexible" V-Chip regulations. The suit was filed after LG allegedly failed to report any sales or pay any royalties under the license, claiming its products used a "fixed" V-Chip system not covered by the patent. The complaint also notes that LG entered into a consent decree with the FCC in 2008 for failing to comply with V-Chip regulations. Plaintiff states it terminated the license agreement in April 2010.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 5,828,402 - "Method and Apparatus for Selectively Blocking Audio and Video Signals"
The Invention Explained
- Problem Addressed: The patent describes that prior art video blocking systems were rigid, assuming a single, consistent content rating scheme would be used for all programs. These systems would need to be "rewired or reprogrammed" if moved to a different geographical region with a different rating system, or if new rating schemes were introduced, making them expensive and difficult to adapt (ʼ402 Patent, col. 2:15-34).
- The Patented Solution: The invention is a field-configurable blocking apparatus. It is designed to receive not only program-specific rating data (e.g., "this movie is rated PG-13") but also "configuration information" that defines the rating system itself. This configuration data can specify the number of rating categories (e.g., violence, language), the levels within each category, and descriptive names for them (ʼ402 Patent, col. 13:1-12). This allows a single device to learn and adapt to multiple, different, or evolving rating systems transmitted by broadcasters without requiring physical modification (ʼ402 Patent, Abstract; col. 13:55-63).
- Technical Importance: This flexible approach enabled a single hardware design to comply with differing rating systems across markets (e.g., the U.S. and Canada) and to accommodate future changes to those systems, a key capability for meeting evolving regulatory mandates like those from the FCC (ʼ402 Patent, col. 17:51-18:20).
Key Claims at a Glance
The complaint does not specify which claims it asserts. Independent claim 7 is representative of the "flexible" system at the heart of the dispute.
- Independent Claim 7 (Method):
- Receiving and storing first configuration information describing a first informational (rating) scheme.
- Receiving and storing second configuration information describing a second, different informational scheme.
- Storing user preference information for both the first and second schemes.
- Receiving a video signal with embedded data that specifies which of the informational schemes is being used and the program's rating levels within that scheme.
- Extracting the embedded data and comparing it with the stored user preferences for the specified scheme.
- Blocking or allowing the video signal based on the outcome of the comparison.
III. The Accused Instrumentality
Product Identification
The complaint accuses LG's "infringing television receivers," including digital television sets, digital converter boxes, digital video recorders, and set-top boxes (Compl. ¶55). Specific accused models include the 37LB5D, 42LB5D, 47LB5D, 52LB5D, 32LB4D, 37LB4D, and 42LB4D (Compl. ¶55).
Functionality and Market Context
The complaint alleges these products are required to incorporate "flexible V-Chip technology" to comply with FCC regulations (Compl. ¶30). The relevant functionality is the ability to block programming based on parental settings. The complaint alleges that LG engineers admitted that its products "parse the rating system for changes and additions" to enable users to "block programs based on a new ... rating system" (Compl. ¶37). This alleged functionality directly relates to the patent's teaching of a system that can adapt to new or modified rating schemes. No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint is a notice pleading and does not contain a detailed claim chart. The following table summarizes the infringement theory for representative Claim 7 based on the narrative allegations.
’402 Patent Infringement Allegations
| Claim Element (from Independent Claim 7) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a) receiving first configuration information ... describing a first informational scheme... c) receiving second configuration information ... describing a second informational scheme | The accused products are alleged to be required to incorporate "flexible V-Chip technology" to comply with FCC rules, which mandate that receivers "must respond to changes in the content advisory system" (Compl. ¶17). This implies the capability to receive and process information defining or modifying a rating scheme. | ¶17, ¶30 | col. 13:1-12 |
| b) storing said first configuration information... d) storing said second configuration information | To use the received configuration information, the system must store it. The complaint alleges LG engineers admitted their products "store" rating system information (Compl. ¶37). | ¶37 | col. 13:20-27 |
| f) receiving a first video signal comprising embedded information specifying at least, either one of said first or second informational schemes... | The accused products are television receivers designed to receive broadcast signals containing V-Chip data (Compl. ¶16, ¶55). | ¶16, ¶55 | col. 1:64-2:4 |
| g) extracting said embedded information and comparing said extracted information with said stored preference information | LG engineers allegedly admitted that the accused products "parse the rating system for changes and additions" to allow blocking based on a "new ... rating system," which requires extracting and processing the embedded data (Compl. ¶37). | ¶37 | col. 11:39-49 |
| h) if the result of said comparison indicates that said first video signal should not be displayed, blocking said first video signal... | This is the core function of the V-Chip. The complaint alleges the accused products have the "ability to block programs" based on user-defined settings (Compl. ¶16, ¶37). | ¶16, ¶37 | col. 3:5-15 |
Identified Points of Contention
- Scope Questions: The central dispute may turn on the definition of the claimed system versus the system LG allegedly implemented. The complaint notes LG's defense was that it used a "fixed V-Chip rating system" instead of a "flexible" one (Compl. ¶35). This raises the question: Does the accused system's functionality meet the claim limitations requiring receipt and implementation of different "informational schemes," or does it only read data according to a single, hard-coded scheme?
- Technical Questions: What is the precise mechanism, if any, within the accused LG products for receiving and processing updates or changes to the rating system itself, as distinct from merely processing rating data for individual programs? The complaint alleges this capability must exist to comply with FCC rules but provides no specific evidence of its implementation.
V. Key Claim Terms for Construction
- The Term: "configuration information"
- Context and Importance: This term appears to be the core of the patented invention's novelty over prior art. The entire dispute, as framed by the complaint, hinges on whether LG's products implemented a "flexible" system (which would process "configuration information") or a "fixed" one. The construction of this term will be critical to determining infringement. Practitioners may focus on this term because its scope will define whether simply responding to minor updates in a rating system is sufficient to infringe, or if the claims require the ability to download and implement entirely new and distinct rating schemes.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent specification suggests the term is not limited to complete, new schemes, stating that "the configuration information may specify only additions to a basic informational scheme, such as the scheme specified by EIA-608" (’402 Patent, col. 14:1-4). This may support an argument that even minor, dynamic updates fall within the claim scope.
- Evidence for a Narrower Interpretation: The patent also describes a more comprehensive process where "configuration information" includes the names of categories, descriptive labels for rating levels, and is transmitted in a separate channel, such as a "barker" channel (’402 Patent, col. 13:28-54). This could support a narrower construction requiring the system to be capable of learning and displaying a full, human-readable rating scheme, not just processing abstract codes.
VI. Other Allegations
Indirect Infringement
The complaint alleges both contributory and active inducement, asserting LG makes, uses, sells, and imports the infringing receivers (Compl. ¶55). The factual basis for inducement would likely rely on LG's sale of products with the infringing feature and the provision of user manuals instructing customers on how to use the parental control functionality.
Willful Infringement
The complaint alleges that LG had actual notice of the '402 patent since at least November 3, 2004, as a result of extensive licensing negotiations (Compl. ¶56). It further alleges that during these negotiations, LG acknowledged that implementing the FCC-mandated "flexible V-Chip" functionality would require using the patented technology, but then proceeded to sell products without paying royalties (Compl. ¶24, ¶25, ¶35).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central question will be one of technical implementation: Does the V-Chip feature in LG’s accused products possess the capability to receive and process "configuration information" to adapt to new or modified rating systems, as claimed in the patent? Or does it operate on a "fixed" system that only recognizes a predefined set of rating codes, potentially placing it outside the scope of the claims?
- A key legal and factual issue will be the effect of the parties' pre-litigation conduct: The complaint alleges that LG's own statements during license negotiations acknowledged the patent's relevance to the "flexible" V-Chip technology mandated by the FCC. The court will have to consider how this extensive history of negotiation and alleged admissions impacts subsequent arguments regarding claim construction and infringement.
