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

U.S. Patent No. 7,650,376 - Content Distribution System for Distributing Content Over a Network, with Particular Applicability to Distributing High-Bandwidth Content

  • 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’s background section describes the problem of delivering high-bandwidth content, such as full video streams, to large online audiences in a "satisfactory manner," which it notes was considered nearly "impossible" at the time due to network bandwidth limitations and the high cost of centralized server infrastructure (’376 Patent, col. 1:28-34, 1:59-63; Compl. ¶¶ 36-38).
  • The Patented Solution: The invention proposes a distributed content delivery architecture to solve this problem. As described in the abstract and detailed description, a central 'core server' controlled by the content provider recruits an 'army' of 'node servers' (e.g., third-party or volunteer computers) to dispense content to end-user 'clients' (’376 Patent, Abstract, col. 10:21-23). The core server acts as a traffic director, identifying which node servers hold the requested content and are topologically best-suited to serve a requesting client, and then facilitates a handoff for the actual content delivery to occur between the node server and the client (’376 Patent, Fig. 1, col. 2:8-24).
  • Technical Importance: This decentralized model presented a method to scale content delivery by leveraging distributed, third-party computing resources, thereby avoiding the significant capital investment required to build and maintain massive, wholly-owned server farms (’376 Patent, col. 4:34-47; Compl. ¶¶ 39, 47).

Key Claims at a Glance

  • The complaint asserts infringement of "one or more claims, including at least Claim 37," and also presents Claim 57 as an exemplary claim subject to the allegations (Compl. ¶¶ 82, 119).
  • Independent Claim 37 (a computer readable storage medium with instructions for):
    • receiving a request from a client for specified content;
    • 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
    • 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 comprising the steps of):
    • 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 AMC+ application and its associated streaming platform (Compl. ¶6).

Functionality and Market Context

The complaint alleges that AMC+ is a streaming platform that functions as a virtual multichannel video programming distributor (v-MVPD), providing on-demand video content to users over the internet (Compl. ¶6). The complaint includes a screenshot from the AMC+ website describing it as a "premium streaming bundle" and a key destination for popular content like "The Walking Dead Universe" (Compl. p. 1, Fig. 1). The complaint asserts that this service necessarily involves "effecting the provision of content over a network" but does not provide specific technical details regarding the architecture of AMC+'s backend content delivery infrastructure (Compl. ¶6).

IV. Analysis of Infringement Allegations

The complaint references a claim chart in an external exhibit that was not provided with the filing (Compl. ¶119, Exhibit 2). The infringement theory is therefore summarized below in prose based on the complaint's narrative allegations.

The complaint alleges that the AMC+ service infringes the ’376 Patent by operating a content delivery system that practices the claimed invention (Compl. ¶¶ 119-122). The infringement theory appears to be that any large-scale video streaming service, like AMC+, must necessarily use a distributed architecture that maps onto the patent's claims. This architecture is depicted in the complaint as a system with a central "Core Server" (101) that coordinates numerous "Node Servers" (102) to deliver content to "Clients" (103) (’376 Patent, Fig. 1, reproduced at Compl. p. 18).

The alleged infringement process follows the patented method illustrated in the complaint, which outlines a specific sequence of communications (’376 Patent, Fig. 2, reproduced at Compl. p. 20). According to this theory, when a user on the AMC+ app (the "client") requests a video, AMC+'s backend system (the "core server") identifies a delivery server within its network (the "node server") that stores the video and is optimally positioned to stream it. The system then allegedly enables the user's app to connect to that node server to receive the content, and later verifies the successful delivery to trigger compensation for the network partner (Compl. ¶¶ 68-69, 79).

  • Identified Points of Contention:
    • Scope Questions: A central dispute may arise over whether AMC+'s CDN infrastructure, which likely consists of commercially operated servers from major providers, qualifies as the "node server" architecture described in the patent. The patent specification discusses recruiting "volunteer server(s)" and using "personal computers of individuals or families," which raises the question of whether the claims are limited to such non-commercial, peer-to-peer arrangements (’376 Patent, col. 2:17, col. 10:42-43).
    • Technical Questions: The complaint does not provide evidence on the specific technical implementation of the AMC+ service. This raises the question of how Plaintiff will prove that the accused system performs the explicit claim step of "communicating to the client the identity of a node server." Modern CDNs may use alternative methods, such as DNS redirection or anycast routing, that do not map directly to this claimed step.

V. Key Claim Terms for Construction

  • The Term: "node server"

  • Context and Importance: This term is fundamental to the claimed distributed architecture. Its construction will be critical in determining whether the claims read on modern commercial CDNs or are confined to the peer-to-peer or "volunteer" computing context described in parts of the specification.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification provides a broad definition, stating node servers are "network sites that are not part of core server 101" and serve as an "'army' enlisted by core server 101 to aid in distributing content" (’376 Patent, col. 10:17-23). This language may support an interpretation that includes any third-party server.
    • Evidence for a Narrower Interpretation: Specific embodiments emphasize recruiting "volunteer server(s)" and using "personal computers of individuals or families" as node servers (’376 Patent, col. 2:17, col. 10:42-43). Arguments made during prosecution to distinguish prior art may also be used to argue for a narrower definition (Compl. ¶¶ 16, 19).

  • The Term: "incentive as compensation"

  • Context and Importance: This term was highlighted during prosecution to overcome prior art, suggesting it is a limitation of potential significance (Compl. ¶16). The dispute will likely focus on whether a standard fee-for-service payment to a commercial CDN provider meets this limitation, or if it requires a more specific inducement arrangement.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The patent lists "cash" as one possible incentive, which could be argued to encompass any form of monetary payment for services rendered (’376 Patent, col. 4:42).
    • Evidence for a Narrower Interpretation: The specification provides numerous non-monetary examples, such as "access to premium content," "free software," and "frequent flyer miles," in the context of inducing network site owners to participate (’376 Patent, col. 4:37-42). This context may support an interpretation that the "incentive" is a specific tool for recruitment, distinct from a standard commercial contract.

VI. Other Allegations

  • Willful Infringement: The complaint does not allege willful infringement. It alleges that the Defendant has knowledge of its infringement "at least as of the service of the present complaint" (Compl. ¶118). This allegation may support a claim for enhanced damages for any infringement that occurs after the filing of the lawsuit but does not establish pre-suit willfulness.

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

  • A dispositive threshold issue will be one of claim viability: what is the legal effect of the Ex Parte Reexamination Certificate that cancelled the asserted claims? The court will need to determine if this action, which occurred after the complaint was filed, renders the plaintiff's infringement claims moot.
  • Assuming the claims remain viable, a core issue will be one of definitional scope: can the term "node server," which is described in key patent embodiments in the context of "volunteer" or personal computers, be construed to cover the professionally managed, commercial servers that constitute the modern Content Delivery Networks used by services like AMC+?
  • A key evidentiary question will be one of technical proof: what evidence can the plaintiff produce to demonstrate that the AMC+ platform performs the specific functions recited in the claims, such as "communicating to the client the identity of a node server," as opposed to using other, more modern and technically distinct content delivery mechanisms?
