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

U.S. Patent No. 7,606,876 - "Media Key for Updateable Content Distribution", issued October 20, 2009

The Invention Explained

  • Problem Addressed: The patent identifies the problem of distributing content on fixed media like CDs, which quickly becomes outdated (e.g., a product catalog with changing prices). It notes that updating such media is impractical for both consumers and providers, as it would require returning the physical media or distributing new copies ('876 Patent, col. 1:12-32).
  • The Patented Solution: The invention proposes a system where a physical, portable medium (e.g., a CD) is encoded with a "Keying Application" and a unique "Source ID." When a user accesses the medium on a network-connected device, the Keying Application launches, connects to a remote "Content Server," and sends the Source ID. The server then uses this ID to deliver specific, customized, and up-to-date content to the user, effectively turning a static piece of media into a gateway for dynamic information ('876 Patent, Abstract; col. 2:57-67; Fig. 1).
  • Technical Importance: This technology provided a mechanism for content providers to leverage physical media distribution channels while overcoming the limitation of static content, enabling targeted and updateable user experiences. ('876 Patent, col. 2:3-7).

Key Claims at a Glance

  • The complaint asserts "one or more claims" without specifying them (Compl. ¶11). The independent claims are analyzed below.
  • Independent Claim 1 (System):
    • At least one network-connected content server for creating and updating information based on a user profile.
    • A "keying application" stored on an external storage medium.
    • The keying application selects a user ID and transmits the user ID and a "storage media identifier" to the content server.
    • A key limitation requires that 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."
  • Independent Claim 9 (Method):
    • Creating original information on a content server and storing it on a storage medium.
    • Identifying a user by associating a "media identifier" with a "user ID."
    • Transmitting the user ID and media identifier to the content server to access a user profile.
    • Creating updated information and transmitting it to the user's electronic device.
  • The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

  • The complaint does not name any specific accused products. It refers generally to "Defendant products identified in the charts incorporated into this Count" and the "Exemplary Defendant Products" (Compl. ¶11). These charts, designated as Exhibit 2, were not filed with the complaint.

Functionality and Market Context

  • The complaint does not provide sufficient detail for analysis of the accused products' functionality or market context beyond the conclusory allegation that they "practice the technology claimed by the '876 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint alleges that infringement is detailed in claim charts provided as Exhibit 2 (Compl. ¶16-17). As Exhibit 2 was not included with the public filing, a detailed claim chart summary cannot be constructed. The complaint’s narrative theory is that the "Exemplary Defendant Products" practice the claimed technology and "satisfy all elements of the Exemplary '876 Patent Claims" (Compl. ¶16).

No probative visual evidence provided in complaint.

  • Identified Points of Contention: Based on the patent language and the general nature of the allegations, the infringement analysis raises several questions:
    • Scope Questions:
      • What is the scope of a "keying application"? The patent describes a "self-contained, user interface" ('876 Patent, col. 3:37-39). A key question will be whether this term can be construed to cover modern software installers, authenticators, or web-based login portals that may be initiated from physical media.
      • What constitutes a "storage media identifier" as recited in the claims, and how does it relate to the "Source ID" described in the specification ('876 Patent, col. 3:1-6)? The relationship between these terms and their application to the accused products will be a central issue.
    • Technical Questions:
      • The complaint provides no facts explaining how the accused products perform the step of selecting a user ID "based on the storage media identifier and other indicia of user identification" as required by Claim 1.
      • What evidence demonstrates that the accused products perform the conditional function of Claim 1, where a server-generated user ID is recorded on the local device specifically "if said external storage media... is non-recordable"?

V. Key Claim Terms for Construction

  • The Term: "keying application" (Claim 1)

  • Context and Importance: This term is the central component of the claimed invention. Its definition will be critical to determining infringement, as Defendant will likely argue that its standard software does not meet the specific functional requirements of a "keying application." Practitioners may focus on this term because it appears to be more specific than a generic software application.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The patent states the keying application interacts with a content server "via the network connection" ('876 Patent, Abstract), which could be argued to cover any software on media that "calls home" to a server.
    • Evidence for a Narrower Interpretation: The specification describes the keying application as launching a "self-contained, user interface" that "eliminates the need for use of any other external programs (i.e., external to the Keying Application) to access the content" ('876 Patent, col. 3:37-44). This suggests the application is not merely a trigger for a standard web browser but is a distinct, standalone program, potentially narrowing its scope.

  • The Term: "storage media identifier" (Claim 1)

  • Context and Importance: This identifier is a core input to the claimed system, used to generate the user's profile. Clarifying its meaning is essential to understanding how the accused products could infringe.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The term itself is generic and could be argued to cover any unique number or code associated with a piece of media, such as a volume serial number.
    • Evidence for a Narrower Interpretation: The specification extensively uses the term "Source ID," which is described as identifying "the distribution point of the media, or the identity/profile of an end user" ('876 Patent, col. 3:1-3). This suggests the "storage media identifier" is not just any serial number but is a specific code imbued with information about the media's origin or intended user, linking it directly to the "keying" function.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that Defendant induces infringement by distributing "product literature and website materials" that instruct end users on how to use the accused products in a manner that allegedly infringes the '876 Patent (Compl. ¶14).
  • Willful Infringement: The complaint bases its willfulness allegation on Defendant's knowledge of the patent gained from the service of the complaint itself (Compl. ¶13, ¶15). The allegation is limited to post-suit conduct.

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

  1. A core issue will be one of definitional scope: can the term "keying application," which the patent describes as a "self-contained" program that connects to a server using a "storage media identifier," be construed broadly enough to read on modern software installation or authentication processes that may be initiated from physical media but operate through standard components like web browsers?

  2. A second key issue will be evidentiary. The complaint lacks any specific factual allegations detailing how the accused products operate. The case will likely depend on whether Plaintiff can produce evidence to show that Defendant’s products perform the specific, multi-step functions of the claims, particularly the creation of a user profile based on a "storage media identifier" and the conditional recording of a user ID on a local device when the source media is non-recordable.
