Case Timeline

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

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

• Issued: October 20, 2009

The Invention Explained

• Problem Addressed: The patent describes the problem of content distributed on physical media, such as a sales catalog on a CD, becoming outdated. Traditional methods for updating this content were impractical, as they required either returning the media for rewriting or distributing an entirely new physical copy. (’876 Patent, col. 1:23-35).
• The Patented Solution: The invention is a system where a physical, portable storage medium (e.g., a CD) contains a "Keying Application" and a unique "Source ID." When a user accesses this medium on a network-connected device, the Keying Application launches and interacts with a remote "Content Server." The application sends the Source ID to the server, which in turn delivers specific, up-to-date content back to the user's device for display, effectively linking a static physical object to a dynamic online experience. (’876 Patent, Abstract; col. 2:11-23).
• Technical Importance: The technology provided a mechanism to bridge the gap between physically distributed media and live, customizable online content, a notable challenge in the era before the widespread adoption of QR codes or mobile application stores.

Key Claims at a Glance

• The complaint asserts infringement of "exemplary claims" identified in an external chart, without specifying them in the complaint's body (Compl. ¶11). The patent’s independent claims are 1, 9, 12, and 22.
• Independent Claim 1 (System Claim) requires:
  • A system for distributing and updating information on a "processor readable portable external storage media."
  • At least one "content server" connected to a network.
  • A "keying application" stored on the media for launching on an electronic device.
  • The keying application selects a user ID and transmits both the user ID and a "storage media identifier" to the content server.
  • The keying application records a user ID (generated by the content server) on the local electronic device if the external storage media is non-recordable.
• The complaint does not explicitly reserve the right to assert dependent claims, but refers generally to "one or more claims of the '876 Patent" (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

• The complaint refers to the accused instrumentalities as the "Exemplary Defendant Products" but does not identify any specific product by name (Compl. ¶11).

Functionality and Market Context

• The complaint does not describe the features or functionality of the accused products. Instead, it states that this information is contained within "charts incorporated into this Count" via an external exhibit, which was not filed with the complaint (Compl. ¶11, ¶16). The complaint makes no allegations regarding the products’ commercial importance or market position.

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint incorporates infringement allegations by reference to claim charts in "Exhibit 2," which was not provided with the filed complaint (Compl. ¶16, ¶17). Therefore, a detailed claim chart summary cannot be constructed from the provided documents. The complaint alleges that the "Exemplary Defendant Products practice the technology claimed by the '876 Patent" and "satisfy all elements of the Exemplary '876 Patent Claims" (Compl. ¶16).

• Identified Points of Contention:
  • Scope Questions: A potential issue is how the claim term "processor readable portable external storage media" (Claim 1) reads on the accused product. The dispute may center on whether the accused product involves a distinct, physically distributed object as described in the patent's embodiments, or if Plaintiff will argue for a broader interpretation.
  • Technical Questions: A central evidentiary question will be what proof exists that the accused product includes a "keying application" that performs the specific functions recited in Claim 1. This includes selecting and transmitting both a "user ID" and a "storage media identifier" and, critically, recording a server-generated user ID on the local device when the originating media is non-recordable (’876 Patent, col. 8:55-68).

V. Key Claim Terms for Construction

• The Term: "keying application"

• Context and Importance: This term is central to the invention, as it describes the software that enables the patented functionality. Its construction will be critical to determining whether the accused software performs the specific, multi-step process required by the claims.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes the application as potentially being a "network browser or browser-like application, which eliminates the need for use of any other external programs" to access the content (’876 Patent, col. 3:41-44).
  • Evidence for a Narrower Interpretation: Claim 1 requires the "keying application" to perform a specific sequence of actions: selecting a user ID, transmitting it with a media identifier, and recording a user ID on the local device if the media is non-recordable (’876 Patent, col. 8:55-68). A narrow construction might require all of these functions to be present.

• The Term: "processor readable portable external storage media"

• Context and Importance: This term defines the physical component that initiates the patented process. The nature of the accused product will determine whether this term is a point of contention.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification states that "any type of media, volatile or non-volatile, can be used (e.g., floppy disk, magnetic tape, EEPROMS, CD, DVD, memory card, etc.)" (’876 Patent, col. 2:63-67).
  • Evidence for a Narrower Interpretation: The patent’s background and embodiments consistently describe a physically distinct object that is distributed to an end user to "key" the system, such as a "mini wallet-sized CD" (’876 Patent, col. 3:21-23). An argument could be made that the term requires a discrete physical item separate from the user's primary computing device.

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). Knowledge is alleged to exist at least from the date of service of the complaint (Compl. ¶15).
• Willful Infringement: The complaint alleges that service of the complaint constitutes "actual knowledge of infringement" and that Defendant's continued infringing activities despite this knowledge are ongoing (Compl. ¶13, ¶14). This provides a basis for alleging post-filing willfulness. The prayer for relief seeks a finding that the case is "exceptional" under 35 U.S.C. § 285 (Compl. ¶ E.i).

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

• An Evidentiary Question: Given the complaint’s complete reliance on an unattached exhibit to identify the accused products and detail the infringement theory, a primary hurdle for the Plaintiff will be to produce evidence demonstrating that any of Defendant's products actually perform the specific combination of functions recited in the asserted claims.
• A Question of Definitional Scope: The case may turn on the construction of "keying application." A core legal issue will be whether this term can be construed to cover general-purpose software or if it is limited to an application that performs the specific sequence of operations recited in Claim 1, including the selection and transmission of multiple identifiers and the conditional recording of a user ID on a local device.
• A Question of Technical Operation: A key factual dispute will likely be whether the accused system meets the claim limitation requiring the "keying application" to record a user ID on the local device if the originating media is non-recordable, a specific fallback mechanism that may not be present in modern software architectures.
