Case Timeline

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

U.S. Patent No. 7,606,876 - “Media Key for Updateable Content Distribution”

• Patent Identification: U.S. Patent No. 7,606,876, “Media Key for Updateable Content Distribution,” issued October 20, 2009.

The Invention Explained

• Problem Addressed: The patent addresses the limitations of traditional content distribution on static media like pre-recorded CDs or DVDs, which quickly become outdated (e.g., with price changes or new inventory) and are impractical to recall for updates (ʼ876 Patent, col. 1:21-38).
• The Patented Solution: The invention proposes a hybrid system where a "processor readable, portable apparatus" (e.g., a CD) is pre-loaded with a "Keying Application" and a unique "Source ID." When a user accesses the media on a network-connected device, the application launches and interacts with a remote "Content Server." This interaction allows the server to deliver specific, updateable content to the user, effectively using the physical media as a "key" to unlock dynamic, customized information (ʼ876 Patent, Abstract; col. 2:10-23).
• Technical Importance: The technology aimed to bridge the gap between the wide-scale distribution model of physical media and the real-time content benefits of the internet, allowing content providers to deliver "live" experiences through a familiar medium (ʼ876 Patent, col. 2:3-9).

Key Claims at a Glance

• The complaint alleges infringement of "one or more claims" and references "Exemplary '876 Patent Claims" in an unprovided exhibit (Compl. ¶11). Independent claim 1 is representative of the asserted system.
• Independent Claim 1 (System Claim) requires:
  • At least one network-connected content server adapted to create and update information for a user profile.
  • A "keying application stored on the external storage media" for launching on an electronic device to select a user ID and transmit it to the server.
  • The profile is generated from factors including a "storage media identifier," a user ID, and transaction histories.
  • A specific mechanism wherein if the external storage media is "non-recordable," the keying application records the server-generated user ID onto the "local electronic device" running the application.

III. The Accused Instrumentality

Product Identification

• The complaint does not name any specific accused products in its main body. It refers generally to "Exemplary Defendant Products" that are identified in charts within an "Exhibit 2" (Compl. ¶11, ¶16). This exhibit was not filed with the complaint.

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused instrumentality's specific functionality or market context. It alleges in general terms that the "Exemplary Defendant Products practice the technology claimed by the '876 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint incorporates by reference claim charts from an unprovided "Exhibit 2" rather than detailing its infringement theory in the pleading itself (Compl. ¶16-17). The following summary is based on the structure of representative claim 1 and the general allegations made. No probative visual evidence provided in complaint.

'876 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central issue may be whether the term "external storage media," which the patent specification exemplifies with physical media like CDs and floppy disks (ʼ876 Patent, col. 6:65-67), can be construed to cover the hardware and software architecture of the unspecified "Exemplary Defendant Products." The complaint does not explain how a modern device or downloaded application meets the "external storage media" limitation.
  • Technical Questions: The complaint does not provide facts explaining how the accused products use a "storage media identifier" from the "media" itself to access a profile, as distinct from using device-generated identifiers or user-provided credentials. It also does not specify how the accused system performs the claimed step of recording a user ID on a local device when the "media" is "non-recordable."

V. Key Claim Terms for Construction

• The Term: "external storage media"

• Context and Importance: The definition of this term appears critical. The case may turn on whether this term is limited to the portable physical media described in the patent (CDs, memory cards) or if it can be interpreted to read on modern hardware configurations, such as a smartphone that downloads an application which then interacts with a peripheral device.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification refers to "any type of processor readable, portable apparatus" ('876 Patent, col. 2:12-13), and the dependent claims list a wide variety of media types, suggesting the term was not intended to be limited to a single format like optical discs ('876 Patent, col. 10:29-32).
  • Evidence for a Narrower Interpretation: The patent’s background is rooted in solving the problem of distributing static physical media ('876 Patent, col. 1:12-38). The detailed description and figures consistently depict a workflow that begins with physical media being provided to an end user ('876 Patent, Fig. 1; col. 3:18-24).

• The Term: "storage media identifier"

• Context and Importance: Practitioners may focus on this term because infringement requires the accused system to use this specific type of identifier to generate a user profile. A key question will be whether the accused products use an identifier from the media as taught, or if they use other identifiers (e.g., device serial number, user login) that fall outside the claim's scope.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent does not narrowly define the term, which could allow for arguing that any unique identifier associated with the initial software/hardware combination meets the limitation.
  • Evidence for a Narrower Interpretation: The specification describes a "Source ID" that is "preinstalled" or "encoded onto the media" to identify a distribution point or user profile, distinct from the user or the electronic device ('876 Patent, Abstract; col. 3:1-9). This suggests the identifier is intrinsic to the "media" itself, not generated by the user's device.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by asserting that Defendant provides "product literature and website materials" that instruct end users on how to use the products in an infringing manner (Compl. ¶14). The knowledge element for inducement is pleaded as arising "[a]t least since being served by this Complaint" (Compl. ¶15).
• Willful Infringement: The complaint alleges Defendant obtained "actual knowledge" of the '876 patent upon service of the complaint and continued to infringe thereafter (Compl. ¶13-14). While the word "willful" is not used, this forms a basis for post-filing willful infringement. The prayer for relief asks for the case to be declared "exceptional" under 35 U.S.C. § 285 (Compl. ¶19.E.i).

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

1. Definitional Scope: A core issue will be whether claim terms rooted in the early 2000s physical media paradigm—specifically "external storage media" and "storage media identifier"—can be construed to encompass the technology of the accused modern consumer electronics, whose specific nature is not yet detailed in the pleadings.

2. Pleading Sufficiency: A threshold question will be whether the complaint, which omits the names of the accused products and the specific factual basis for infringement in favor of incorporating an unprovided exhibit, meets the plausibility pleading standards required by federal court rules to provide Defendant with adequate notice of the claims against it.

3. Factual Correspondence: Beyond claim construction, a key evidentiary question will be whether Plaintiff can demonstrate that the accused system performs the specific functions claimed, particularly the use of an identifier from the "media" to differentiate content and the conditional recording of a user ID on a local device when the "media" is "non-recordable."
