Case Timeline

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

• Patent Identification: U.S. Patent No. 7,650,376, "Content Distribution System for Distributing Content Over a Network, with Particular Applicability to Distributing High-Bandwidth Content," issued January 19, 2010.

The Invention Explained

• Problem Addressed: The patent addresses the technical challenge of delivering high-bandwidth content, such as video streams, over the internet to large, geographically dispersed audiences using the limited network capabilities of the time (Compl. ¶¶37, 40; ’376 Patent, col. 1:28-34). Centralized server-client models were prone to bottlenecks and failure when faced with many asynchronous user requests, resulting in a poor user experience ('376 Patent, col. 1:57-66).
• The Patented Solution: The invention describes a distributed content delivery system. A central "core server" acts as a directory and coordinator, enlisting an "army" of third-party "node servers" to store and serve content on its behalf ('376 Patent, col. 10:20-23). As illustrated in Figure 1 of the patent, when a "client" requests content, the core server identifies an appropriate node server (e.g., one that is topologically proximate) and communicates its identity to the client, which then retrieves the content directly from that node server (Compl. ¶¶57, 59; ’376 Patent, Abstract). The system also proposes offering an "incentive" to the owners of node servers as compensation for distributing the content ('376 Patent, col. 4:35-49).
• Technical Importance: This architecture provided a solution to the scalability and reliability problems of early internet content delivery, forming a conceptual basis for modern Content Delivery Networks (CDNs) that are essential for today's video streaming services (Compl. ¶¶43, 92).

Key Claims at a Glance

• The complaint asserts independent claims 37 and 57 ('376 Patent; Compl. ¶123).
• Independent Claim 37 (a computer readable storage medium):
  • instructions for receiving a request from a client for specified content;
  • instructions for communicating to the client the identity of a node server having the specified content stored thereon, thereby enabling the client to request transmission of the specified content from the node server; and
  • instructions for ascertaining that the node server transmitted the specified content to the client, wherein an owner of the node server is offered an incentive as compensation for transmission of the specified content to the client.
• Independent Claim 57 (a method):
  • identifying at a core server a network site that will act as a node server for distribution of specified content;
  • providing from the core server the specified content to the node server;
  • receiving at the core server a request from a client for the specified content;
  • communicating from the core server the identity of the node server to the client to enable the client to request transmission of the specified content from the node server; and
  • ascertaining at the core server that the node server transmitted the specified content to the client, wherein an owner of the node server is offered an incentive as compensation for transmission of the specified content to the client.

III. The Accused Instrumentality

Product Identification

• The "Crackle Application system" and the "PCF Application system," which collectively include the Crackle and Popcornflix websites, as well as associated mobile, smart device, console, and streaming device applications (Compl. ¶¶123, 136).

Functionality and Market Context

• The complaint alleges the accused systems provide on-demand streaming of video content to users (Compl. ¶127). The core of the infringement allegation is that these systems operate on a distributed architecture where Defendants' central servers ("core server") direct a user's device ("client") to retrieve video content from "third-party servers" ("node servers") (Compl. ¶¶126-127). The complaint includes a screenshot of the Crackle website's user interface, which allows users to browse and select from a library of movies and TV shows for streaming (Compl. p. 51). Another included visual, a flowchart from the patent's Figure 2, illustrates the multi-step communication process between the core server, node servers, and clients that the complaint alleges the accused systems perform (Compl. p. 22).

IV. Analysis of Infringement Allegations

'376 Patent Infringement Allegations (Claim 37)

'376 Patent Infringement Allegations (Claim 57)

• Identified Points of Contention:
  • Scope Questions: A central dispute may arise over whether the "third-party servers" used by modern streaming services like Crackle (likely commercial CDNs) meet the definition of a "node server" as taught in the patent. The patent specification includes examples of "volunteer server(s)" and "personal computers of individuals or families" acting as node servers ('376 Patent, col. 2:18-19; col. 10:40-42), which may support a narrower construction than the commercial arrangement alleged in the complaint (Compl. ¶132).
  • Technical Questions: The complaint's allegation for the "ascertaining...for...incentive" limitation is based on the assertion that using third-party servers "necessitates" payment (Compl. ¶132). The court will need to determine if the accused system performs the specific feedback loop recited in the claim—verifying transmission for the purpose of triggering compensation—or if the defendants simply have a standard commercial hosting contract that does not map onto this claim element.

V. Key Claim Terms for Construction

The Term: "node server"

• Context and Importance: This term's construction is fundamental to the infringement analysis. If the "third-party servers" used by Defendants are not "node servers" as defined by the patent, the infringement claims may fail. Practitioners may focus on this term because the patent's examples differ from the likely commercial reality of the accused systems.
• Intrinsic Evidence for a Broader Interpretation: The patent defines a node server as a network site that "assists a core server in distributing content" ('376 Patent, col. 10:17-19), language that could arguably cover any third-party server in a CDN.
• Intrinsic Evidence for a Narrower Interpretation: The specification repeatedly refers to node servers as "volunteer server(s)" and provides explicit examples of "personal computers of individuals or families" participating in the network, suggesting a non-commercial, peer-to-peer-like model ('376 Patent, col. 2:18-19; col. 10:40-42).

The Term: "ascertaining that the node server transmitted the specified content to the client, wherein an owner of the node server is offered an incentive as compensation"

• Context and Importance: This limitation was a key point of distinction over prior art during prosecution (Compl. ¶¶20, 23). Proving that the accused system performs this specific two-part function—verifying delivery for the purpose of providing compensation—is critical for the Plaintiff.
• Intrinsic Evidence for a Broader Interpretation: The patent describes the incentive broadly, including "cash, or some combination of such incentives" ('376 Patent, col. 4:42-43), which could support an argument that any payment to a third-party server owner qualifies.
• Intrinsic Evidence for a Narrower Interpretation: The specification details a system where incentives can be made variable based on performance, such as bandwidth, latency, or time of day ('376 Patent, col. 22:1-25). A defendant may argue that a flat-rate commercial contract with a CDN does not meet the specific, performance-based incentive structure taught and claimed.

VI. Other Allegations

Indirect Infringement

• The complaint focuses on direct infringement by Defendants for making and using the accused systems (Compl. ¶133). While there is no separate count for indirect infringement, it alleges that any direct infringement by end-users occurs "under the direction or control of Crackle" (Compl. ¶¶133, 146).

Willful Infringement

• Willfulness is alleged based on post-suit conduct. The complaint asserts that Defendants had constructive notice of the ’376 Patent since its issuance and will have actual notice upon service of the complaint, making any subsequent infringement knowing and willful (Compl. ¶¶134-135, 147-148).

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

1. A core issue will be one of definitional scope: can the term "node server," which the patent describes using peer-to-peer examples like "volunteer server(s)" and personal computers, be construed to cover the commercial, third-party Content Delivery Network (CDN) servers likely used by the accused streaming services?
2. A key evidentiary question will be one of functional proof: what evidence can Plaintiff produce to demonstrate that Defendants' systems perform the specific claimed step of "ascertaining" content delivery for the express purpose of providing a performance-based "incentive," as opposed to merely engaging in a standard commercial relationship with a CDN provider?
3. A significant background issue will be the patent’s validity: given that the asserted claims were cancelled in an ex parte reexamination proceeding that concluded after the complaint was filed, the underlying strength of the patent is in question, which may heavily influence the trajectory and potential resolution of the case.
