Case Timeline

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

• Patent Identification: U.S. Patent No. 7,606,876, “Media Key for Updateable Content Distribution,” issued October 20, 2009. (Compl. ¶9; ’876 Patent, front page).

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

The Invention Explained

• Problem Addressed: The patent describes a problem from the early 2000s: content distributed on physical media like CD-ROMs was static. Updating this content, such as a product catalog, was impractical because it required the provider to distribute entirely new physical media to every user. (’876 Patent, col. 1:15-40).
• The Patented Solution: The invention proposes a hybrid system that bridges physical media with dynamic online content. A portable storage medium (e.g., a CD) is pre-loaded with a "Keying Application" and a unique "Source ID." When a user places this medium into a network-connected computer, the Keying Application automatically launches, connects to a remote Content Server, and transmits the Source ID. The server then uses this ID to deliver customized, up-to-date content back to the user's device, effectively turning the static physical medium into a key for accessing dynamic information. (’876 Patent, Abstract; col. 2:11-23).
• Technical Importance: This system allowed content providers to use physical media for marketing and distribution while ensuring the end-user always received the most current information, solving the obsolescence problem inherent in pre-recorded media. (’876 Patent, col. 2:4-8).

Key Claims at a Glance

The complaint alleges infringement of "exemplary claims" identified in an external chart (Exhibit 2) that was not attached to the publicly filed complaint (Compl. ¶11). As such, the specific asserted claims are not identified in the provided document. Independent Claim 1 is representative of the system claimed by the patent.

• 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 a "processor readable portable external storage media."
  • The keying application is for launching on an electronic device, selecting a user ID, and transmitting 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 user indicia.
  • If the storage media is non-recordable, the keying application records the user ID (generated by the server) onto the local electronic device.

The complaint does not explicitly reserve the right to assert dependent claims, but generally alleges infringement of "one or more claims." (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products, methods, or services in the main body of the document. It refers to "Exemplary Defendant Products" that are purportedly identified in "the charts incorporated into this Count" via Exhibit 2. (Compl. ¶11, ¶16). This exhibit was not attached to the filed complaint.

Functionality and Market Context

The complaint provides no description of the relevant technical features or functionality of any accused instrumentality, deferring entirely to the unattached Exhibit 2. (Compl. ¶16). Similarly, no allegations regarding the commercial importance or market position of any accused product are made in the complaint's text.

IV. Analysis of Infringement Allegations

The complaint’s infringement allegations are made by incorporating by reference claim charts from an unattached Exhibit 2. (Compl. ¶17). The complaint narratively 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). Without the exhibit, a detailed, element-by-element analysis of the infringement allegations is not possible.

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  Based on the patent's focus and the likely nature of modern LG products (e.g., smart TVs, connected appliances), the infringement analysis may raise several key questions.
  • Scope Questions: A primary issue may be whether the term "processor readable portable external storage media," which the patent describes as a distributable item like a CD-ROM (’876 Patent, col. 1:28-32), can be interpreted to cover the internal, non-volatile memory of a modern, integrated smart device. The dispute would question whether software embedded in a device at a factory is equivalent to a distinct medium "distributed to... end users" post-sale as contemplated by the patent. (Compl. ¶11; ’876 Patent, col. 3:19-22).
  • Technical Questions: A factual question will be what component of an LG device constitutes the claimed "keying application stored on the external storage media." (’876 Patent, col. 7:55). Further, it may be disputed what data serves as the "storage media identifier" and whether the accused system uses it to create a "profile" for delivering updated information in the manner claimed.

V. Key Claim Terms for Construction

• The Term: "processor readable portable external storage media" (Claim 1)

  • Context and Importance: The construction of this term appears central to the dispute. The patent's viability against modern integrated electronics may depend on whether this term is limited to discrete, user-handled media or can be read more broadly to include embedded memory.
  • Intrinsic 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). The inclusion of "EEPROMS," a type of memory often integrated directly into electronic devices, may support an interpretation that is not strictly limited to media physically separate from the host device.
  • Evidence for a Narrower Interpretation: The patent’s background and detailed description consistently frame the invention in the context of solving a problem with physically distributed media, such as a "mail-order retail content provider" sending a "sales catalog onto a CD" to a consumer. (’876 Patent, col. 1:28-30). This context, along with examples like a "mini wallet-sized CD" (’876 Patent, col. 3:21), suggests the term refers to a discrete object a user receives and inserts into a device.

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

  • Context and Importance: The definition of this term is critical to identifying the infringing software component. Practitioners may focus on whether this term requires a standalone application, as opposed to an integrated function of a larger operating system.
  • Intrinsic Evidence for a Broader Interpretation: The patent describes the application's function—launching, connecting to a server, and exchanging identifiers—without imposing rigid structural limitations. The description of it as a potential "network browser or browser-like application" suggests a degree of flexibility. (’876 Patent, col. 4:41-43).
  • Evidence for a Narrower Interpretation: The patent states that "launching the Keying Application starts a self-contained, user interface" that is "external to the Keying Application." (’876 Patent, col. 4:37-43). This could support a narrower construction requiring a distinct, self-contained software module rather than a deeply embedded, non-user-facing system process.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials inducing end users... to use its products in the customary and intended manner that infringes the ’876 Patent." (Compl. ¶14). The specific materials are said to be referenced in the unattached Exhibit 2. (Compl. ¶14).
• Willful Infringement: The allegation of willfulness is based on knowledge acquired from the filing of the lawsuit. The complaint asserts that the "service of this Complaint... constitutes actual knowledge of infringement" and that Defendant's continued alleged infringement thereafter is willful. (Compl. ¶13-14).

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

• Definitional Scope: A central issue will be one of definitional scope: can the term "processor readable portable external storage media," rooted in the patent's context of distributable CD-ROMs, be construed to encompass the integrated, non-removable memory of a modern smart device? The outcome of this claim construction battle could be dispositive.
• Evidentiary Burden: A key question will be one of evidentiary mapping: given the complete reliance on an unattached exhibit, can the plaintiff produce sufficient factual evidence to demonstrate that the accused LG products contain a "keying application" and use a "storage media identifier" to perform the specific functions required by the asserted claims, or is there a fundamental mismatch in technical operation?
• Temporal Application: The case presents a classic question of temporal application. The court will need to determine whether the accused technology, operating in a modern ecosystem of internet-of-things devices, is merely an updated version of the 2003-era concept, or if it represents a different technological paradigm beyond the scope of the patent's claims.
