Case Timeline

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

U.S. Patent No. 5,768,508 - Computer Network System and Method for Efficient Information Transfer, issued June 16, 1998

The Invention Explained

• Problem Addressed: The patent addresses the underutilization of network bandwidth, noting that "no use is made of free space between information packets" and the "entire bandwidth of an idle link is wasted" when a user is not actively requesting data (’508 Patent, col. 1:31-36). This inefficiency makes it difficult for information providers to furnish targeted content to users without resorting to undesirable methods like "junk mail" (’508 Patent, col. 1:64).
• The Patented Solution: The invention proposes a computer network system that connects information providers with users to transfer "target information" (e.g., commercial content) by utilizing "otherwise idle bandwidth" (’508 Patent, Abstract; col. 2:12-16). A "master program" receives a unique "node ID" from a user, accesses a database to find profile information and a corresponding "target information reference," and then transfers the target information in the background, minimizing interference with the user's primary "non-target" network traffic (’508 Patent, col. 2:32-51).
• Technical Importance: The described technology provides a method for delivering background content to users in a way that is tailored to their interests and does not degrade the performance of their primary, interactive network activities (’508 Patent, col. 2:9-16).

Key Claims at a Glance

• The complaint asserts at least independent method claim 26 (Compl. ¶11).
• The essential elements of Claim 26 include:
  • A method, performed by a master program, of connecting an information provider and a user node.
  • Registering the user node at a master node.
  • Receiving a node ID from the user node.
  • Accessing a master database for profile information corresponding to the node ID.
  • Transmitting to the user node a "target information reference" which is a pointer to "target information" to be delivered "while transferring non-target information without additional communication delay."

III. The Accused Instrumentality

Product Identification

• The complaint identifies the accused instrumentalities as "Wi-Fi routers that prioritize Internet traffic," specifically including the "AC5300 Nighthawk X8 Tri-Band Wi-Fi Router" (Compl. ¶11).

Functionality and Market Context

• The complaint alleges that the accused routers perform the patented method by managing traffic on a user's network (Compl. ¶11). The routers are alleged to use a "Dynamic QoS" (Quality of Service) feature to "optimize data traffic management" by prioritizing certain types of data, such as streaming or gaming, over other types of data, such as large file transfers from BitTorrent (Compl. ¶13). This prioritization is alleged to ensure that high-priority "non-target information" is transferred "without additional communications delay" caused by the lower-priority "target information" (Compl. ¶13).

IV. Analysis of Infringement Allegations

No probative visual evidence provided in complaint.

’508 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question may be whether a home router's local network management functions fall within the scope of the claimed "master program" connecting an "information provider" and a "user node." The patent describes a system where the "master program" is a large server, distinct from the user's local equipment, that interacts with external "information providers" (’508 Patent, Fig. 1; col. 3:40-47). The complaint appears to map the claimed "master program," "master node," and "master database" all onto the single accused router (Compl. ¶11-13).
  • Technical Questions: The infringement analysis may turn on whether the accused router's "Dynamic QoS" feature, which prioritizes one type of user-initiated traffic over another, performs the same function as the claimed method. The patent teaches transferring "target information" by using "otherwise idle bandwidth" so as not to interfere with "normal network traffic" (’508 Patent, Abstract; col. 2:12-16). The complaint's theory characterizes different types of "normal network traffic" (e.g., BitTorrent vs. gaming) as "target" and "non-target," which raises a question of functional and technical correspondence.

V. Key Claim Terms for Construction

• The Term: "profile information"

  • Context and Importance: The infringement theory hinges on equating a router's technical device identifiers with the claimed "profile information." Practitioners may focus on this term because the patent's description of "profile information" appears different from the "profile information" identified in the complaint.
  • Intrinsic Evidence for a Broader Interpretation: The term itself is not explicitly defined, which could support an argument that it should be given its plain and ordinary meaning, potentially encompassing any information associated with a user or node.
  • Intrinsic Evidence for a Narrower Interpretation: The specification provides specific examples of "user profile information, such as age, gender, educational level, work status, items of interests, and hobbies" (’508 Patent, col. 4:1-4). This explicit list could be used to argue that the term requires demographic or interest-based data, not merely technical network identifiers like a MAC address, IP address, and device name (Compl. ¶12).

• The Term: "target information"

  • Context and Importance: The definition of this term is critical, as the complaint maps it to a specific category of user-initiated internet traffic (e.g., BitTorrent files) (Compl. ¶13). Whether this mapping is appropriate under the patent's teachings will be a key issue.
  • Intrinsic Evidence for a Broader Interpretation: The term is used generally throughout the patent, and one could argue it covers any information designated for background transfer.
  • Intrinsic Evidence for a Narrower Interpretation: The patent consistently frames "target information" as content furnished by "information providers" that is delivered to a user in the background, separate from the user's primary, active requests for "non-target information" (’508 Patent, col. 1:37-43; col. 2:36-41). This could support an argument that "target information" cannot be user-initiated traffic, but rather must be content pushed to the user by the system.

VI. Other Allegations

The complaint does not contain specific counts or factual allegations for indirect or willful infringement.

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

• A core issue will be one of architectural scope: can the patent’s distributed client-server architecture—which describes a remote "master program" and "master database" connecting separate "information providers" to users—be construed to read on the functions of a single, self-contained home Wi-Fi router managing traffic on a local network?
• A key question will be one of functional definition: does a router's Quality of Service (QoS) feature, which prioritizes one active stream of user-requested data over another, constitute the claimed method of transferring distinct "target information" into the "free space between information packets" or during "idle" link time to avoid delaying "normal network traffic"?
• The case may also turn on the interpretation of "profile information": does a router's internal table of technical network identifiers (MAC and IP addresses) meet the claim requirement for "profile information," which the patent specification exemplifies as user demographic and interest data?
