Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 7,606,876 - Media Keying for Updateable Content Distribution

The Invention Explained

• Problem Addressed: The patent addresses the limitations of distributing content on static physical media like CDs. Information pre-recorded on such media quickly becomes outdated (e.g., prices in a retail catalog), and updating it is impractical, requiring the user to be sent a new physical copy ('876 Patent, col. 1:20-39).
• The Patented Solution: The invention proposes a system where a physical, portable medium (e.g., a mini-CD) is provided to an end-user. This medium contains a "Keying Application" and a unique "Source ID." When the user accesses the medium on a network-connected computer, the Keying Application launches and contacts a remote content server, sending the Source ID. The server then uses this ID to deliver specific, customized, and up-to-date content to the user's device for display ('876 Patent, Abstract; col. 2:11-23). This process is illustrated in the system architecture of Figure 4, which shows the "Media with Keying Application" (420) connecting a "Local User System" (430) to a remote "Content Server" (450) ('876 Patent, Fig. 4).
• Technical Importance: This approach combines the marketing utility of a tangible promotional item with the flexibility of delivering dynamic, real-time information from a centralized server, overcoming the static nature of traditional physical media distribution ('876 Patent, col. 2:3-7).

Key Claims at a Glance

• The complaint asserts infringement of one or more "exemplary claims" without specifying them (Compl. ¶11). Independent claim 1 is representative of the system.
• Independent Claim 1 (System Claim) Elements:
  • At least one content server connected to a network, adapted for automatically creating and updating information according to a user profile.
  • A "keying application" stored on an external, portable storage medium for launching on an electronic device.
  • The keying application selects a user ID (user ID) and transmits the user ID and a "storage media identifier" to the content server.
  • The keying application selects the user ID based on the storage media identifier and other indicia of user identification.
  • If the external storage medium is non-recordable, the keying application records the user ID (generated by the content server) on the local electronic device running the application.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused products by name. It refers generally to "Defendant products identified in the charts incorporated into this Count below (among the 'Exemplary Defendant Products')" (Compl. ¶11). These charts, contained in a referenced Exhibit 2, are not attached to the filed complaint.

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the functionality or market context of any accused product. It alleges in a conclusory manner that the "Exemplary Defendant Products practice the technology claimed by the '876 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint incorporates its substantive infringement allegations by reference to claim charts in an external "Exhibit 2," which was not provided with the public filing (Compl. ¶17). The narrative alleges that the unspecified "Exemplary Defendant Products" satisfy all elements of the asserted claims (Compl. ¶16). Without the charts or specific product information, a detailed element-by-element analysis is not possible.

No probative visual evidence provided in complaint.

Identified Points of Contention

• Based on the patent's claims and the abstract nature of the allegations, the dispute may raise several core questions:
  • Technical Questions: A central evidentiary issue will be whether Defendant's products actually employ a physical "external storage media" containing a dedicated "keying application" that initiates the content delivery process. The court will need to determine if Plaintiff can provide evidence that Defendant's systems operate according to this specific architecture, as opposed to conventional content access methods (e.g., a user navigating to a website with a standard browser).
  • Scope Questions: The analysis may focus on whether the functionality of any accused software constitutes a "keying application" as claimed. A potential dispute is whether a standard software installer or a web wrapper application distributed on a physical medium meets the claim limitation of an application that "selects the user ID based on the storage media identifier" and records a server-generated user ID on the local device ('876 Patent, col. 7:56-64).

V. Key Claim Terms for Construction

• The Term: "keying application"

• Context and Importance: This term is the functional heart of the claimed invention. Its definition is critical because the infringement analysis will depend on whether software on Defendant's products performs the specific functions recited in the claims for the "keying application". Practitioners may focus on whether this term requires a standalone, purpose-built application or if it can read on more generic software that performs similar functions.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent describes the application in functional terms, such as its ability to check for a network connection, send identifiers to a server, and display returned content, suggesting any software performing these functions could qualify (Compl. ¶ '876 Patent, col. 4:39-62).
  • Evidence for a Narrower Interpretation: The specification describes the "keying application" as launching a "self-contained, user interface" that may be a "network browser or browser-like application, which eliminates the need for use of any other external programs" ('876 Patent, col. 3:37-44). This could support a narrower construction requiring an all-in-one application, distinct from a standard web browser or a simple launcher.

• The Term: "storage media identifier"

• Context and Importance: This identifier is the "key" that links the physical medium to the customized content. The dispute will likely turn on what kind of data in an accused system qualifies as this identifier and how it is used to generate a "profile" as required by the claim ('876 Patent, col. 7:49-54).

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claim language itself is broad, not specifying the format of the identifier. This could support an interpretation where any unique code or serial number on the media qualifies.
  • Evidence for a Narrower Interpretation: The specification states the "Source ID" (used synonymously) "may identify the distribution point of the media, or the identity/profile of an end user who will be given the media" (e.g., a customer who shopped in a specific store department) ('876 Patent, col. 3:1-6). This suggests the identifier is not merely a serial number but contains or points to specific profile information, potentially narrowing its scope.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials inducing end users and others to use its products in the customary and intended manner that infringes the '876 Patent" (Compl. ¶14).
• Willful Infringement: The willfulness allegation is based on knowledge of infringement acquired "at least since being served by this Complaint," establishing a basis for potential post-filing willful infringement (Compl. ¶13, ¶15).

VII. Analyst’s Conclusion: Key Questions for the Case

• A primary issue will be one of evidentiary sufficiency: Given that the complaint lacks specific product identifications and omits the referenced infringement charts, a threshold question is whether Plaintiff can produce concrete evidence demonstrating that any of Defendant's products actually practice the specific system architecture recited in the claims, particularly the use of a physical medium as a "key."
• The case will also likely involve a core question of definitional scope: Can the term "keying application", described in the patent as a "self-contained" and "browser-like" interface, be construed to cover potentially more generic software functionalities in Defendant's products? The outcome of this construction could be dispositive for infringement.
• A third key question will be one of functional mapping: Does any accused system actually use a "storage media identifier" to create and update a user "profile" for delivering customized content, as required by claim 1, or is there a fundamental mismatch between the patent's specific data-handling method and the operation of Defendant's technology?
