  • Case Identification: 1:24-cv-06027, S.D.N.Y., 08/08/2024
  • Venue Allegations: Venue is alleged to be proper based on Defendant Fastly, Inc. maintaining a regular and established business presence in the Southern District of New York.
  • Core Dispute: Plaintiff alleges that Defendant’s Content Delivery Network (CDN) service infringes a patent related to systems and methods for distributing high-bandwidth content over a network using a distributed architecture of core and node servers.
  • Technical Context: The technology concerns Content Delivery Networks (CDNs), a foundational internet infrastructure for efficiently distributing data-intensive content, such as streaming video and web applications, to geographically dispersed users.
  • Key Procedural History: The complaint details a lengthy prosecution history for the asserted patent, including multiple rejections over prior art (e.g., "Kenner") and applicant arguments distinguishing the invention based on its unique architecture for identifying and using node servers, and its use of an incentive model. Notably, the complaint was filed on or near the patent's expiration date, which appears to include a significant Patent Term Adjustment. A subsequent Ex Parte Reexamination Certificate (US 7,650,376 C1), requested on June 21, 2024, and issued on July 28, 2025, cancelled all asserted independent claims, including exemplary claims 37 and 57, a development that raises fundamental questions about the continued viability of this action.

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: At the time of the invention, distributing high-bandwidth content like video over the internet was severely limited by network bandwidth, server capacity, and cost (Compl. ¶¶34-37; ’376 Patent, col. 1:57-63). Conventional client-server models, where a central provider served all users directly, could not scale efficiently, leading to poor user experiences, system crashes, and an inability to offer on-demand content to large audiences (Compl. ¶¶39, 43; ’376 Patent, col. 1:59-2:4).
  • The Patented Solution: The patent describes a distributed architecture to solve this problem. The system uses a central "core server" that acts as a coordinator rather than the sole distributor of content (Compl. ¶51). The core server recruits an "army" of third-party "node servers" (e.g., personal computers or other network devices) to store and serve content to end-users ("clients") (Compl. ¶58; ’376 Patent, col. 2:15-19). When a client requests content, the core server identifies a suitable node server—based on factors like network proximity—and communicates that node server's identity to the client, which then retrieves the content directly from the node server (Compl. ¶¶62-65; ’376 Patent, Fig. 2). The system also proposes offering an "incentive" to the owners of node servers as compensation for their participation (Compl. ¶17; ’376 Patent, col. 4:35-48).
  • Technical Importance: This distributed, incentivized model for content delivery was presented as an unconventional solution to the scaling problems of the early internet, providing a blueprint for the architecture of modern Content Delivery Networks (CDNs) that are now essential for global internet services (Compl. ¶¶48, 51).

Key Claims at a Glance

  • The complaint identifies independent claims 37 (computer readable medium) and 57 (method) as exemplary (Compl. ¶¶82-83). The primary infringement count focuses on Claim 37 (Compl. ¶119).
  • The essential elements of independent claim 37 are:
    • 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;
    • enabling the client to request transmission from that node server; and
    • ascertaining that the node server transmitted the content, wherein the node server's owner is offered an incentive as compensation for the transmission.
  • The complaint alleges infringement of "one or more claims, including at least Claim 37," suggesting the right to assert other claims, including dependent claims, is preserved (Compl. ¶119).

III. The Accused Instrumentality

Product Identification

The accused instrumentality is Defendant’s "CDN (content delivery network), which is a globally distributed HTTP network of cache servers for delivering content, such as webpages, videos, and files to the users, stored in cache servers" (Compl. ¶7).

Functionality and Market Context

The complaint describes the accused CDN at a high level, framing its function within the patented architecture (Compl. ¶7). The complaint alleges that this type of distributed network is the backbone of modern "streaming" and represents a technological improvement over the prior art systems that the patent sought to replace (Compl. ¶¶89, 97). The complaint does not, however, provide specific technical details on the operation of Fastly's CDN, instead relying on the patent's framework to describe its alleged function.

IV. Analysis of Infringement Allegations

The complaint references a claim chart in "Exhibit B" to detail its infringement allegations; however, this exhibit was not included with the filed complaint provided for analysis (Compl. ¶¶119, 122). In the absence of the chart, the infringement theory is summarized from the complaint's narrative allegations.

The complaint alleges that Defendant’s CDN practices the patented method for distributing content. The narrative theory suggests that Fastly's CDN operates as the claimed distributed system, with its central control plane functioning as the "core server" and its global edge servers functioning as the "node servers" (Compl. ¶¶7, 51). The complaint contains a system diagram, reproduced from the patent as Figure 1, to illustrate this alleged architecture of a core server (101) coordinating distributed node servers (102) and clients (103) (Compl. ¶56, p. 18).

The infringement theory follows the process described in the patent and depicted in the complaint's Figure 2 flowchart (Compl. ¶60, p. 20). This allegedly includes receiving a content request from a user (client), identifying an optimal edge server (node server) to serve the content, communicating that server’s identity to the client so it can connect directly, and subsequently verifying that the content was delivered to provide a basis for compensation (Compl. ¶¶69-70, 80). The complaint asserts these steps provide a "more reliable and scalable system" than what existed previously (Compl. ¶70). The allegations concerning the "ascertaining" and "incentive" elements are framed in general terms based on the patent's disclosure, without providing specific facts about how Fastly's commercial CDN implements these particular functions.

V. Key Claim Terms for Construction

  • The Term: "node server"

    • Context and Importance: The definition of this term is critical to determining the scope of the claims. Practitioners may focus on this term because the patent specification and the complaint's arguments repeatedly characterize "node servers" as devices owned by third parties and recruited as "volunteers," which may be distinct from the integrated, proprietary server network of a modern commercial CDN (Compl. ¶¶41, 48, 58).
    • Intrinsic Evidence for a Broader Interpretation: The claims themselves do not explicitly require third-party ownership. The specification defines a node server functionally as any "network site that assists a core server in distributing content on behalf of the core server to one or more clients" (’376 Patent, col. 10:17-20).
    • Intrinsic Evidence for a Narrower Interpretation: The Abstract describes the invention as "recruiting network site(s) to act as volunteer server(s)" (’376 Patent, Abstract). The complaint itself heavily emphasizes the use of "distributed, scalable third-party-owned node server-based systems" as a key inventive aspect (Compl. ¶48). This language could support an interpretation limiting "node servers" to entities separate from and not owned by the core server operator.

  • The Term: "incentive as compensation for transmission"

    • Context and Importance: This limitation in claim 37 requires not just an "incentive," but one offered specifically "as compensation for transmission." The case may turn on whether the commercial arrangements between a CDN provider like Fastly and its partners or customers meet this specific requirement.
    • Intrinsic Evidence for a Broader Interpretation: The specification provides a non-exhaustive list of potential incentives, including "premium content," "loyalty program credits," "cash, or some combination," suggesting the term is not limited to a single form of payment (’376 Patent, col. 4:38-44).
    • Intrinsic Evidence for a Narrower Interpretation: The phrasing "compensation for transmission" could be argued to require a direct quid-pro-quo payment tied to a specific delivery act, rather than a general business agreement, peering arrangement, or a customer's subscription fee. The patent discusses varying the incentive based on performance, such as bandwidth and time of day, reinforcing a direct link between the compensation and the specific act of transmission (’376 Patent, col. 22:20-55).

VI. Other Allegations

  • Indirect Infringement: The complaint does not plead specific facts to support claims for induced or contributory infringement, and no separate count for indirect infringement is included.
  • Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. It alleges that Defendant has knowledge of its infringement "at least as of the service of the present complaint," which could form a basis for seeking enhanced damages for any post-filing infringement but does not allege pre-suit willfulness (Compl. ¶118).

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

  • A foundational issue for the case is procedural and existential: Given that the asserted independent claims (37 and 57) were cancelled in an ex parte reexamination proceeding requested before the complaint was filed, the primary question is whether the lawsuit has any viable basis to proceed. The cancellation of the asserted claims appears to render the infringement allegations moot.

  • Assuming the case were to proceed, a core substantive issue would be one of definitional scope: Can the term "node server", which the patent repeatedly describes in the context of recruited third-party "volunteers," be construed to cover the integrated, proprietary edge servers of a modern commercial CDN? Similarly, can the commercial terms of a CDN service satisfy the claim requirement of an "incentive as compensation for transmission" offered to the node server owner?

  • A key evidentiary question would be one of factual proof: The complaint details the patented method but provides no specific facts about how the accused CDN performs the claimed "ascertaining" and "incentive" steps. A central challenge for the plaintiff would be to produce evidence demonstrating that the internal operations of Defendant's system map onto these specific claim limitations.
