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

U.S. Patent No. 7,177,275 - Scheduling method and system for communication systems that offer multiple classes of service (Issued Feb. 13, 2007)

The Invention Explained

• Problem Addressed: The patent describes a challenge in communication systems where user bandwidth requests can exceed the available bandwidth ('275 Patent, col. 1:40-42). In systems that offer different "classes of service" (CoS) or "quality of service" (QoS)—such as for real-time voice versus best-effort web browsing—a simple first-come, first-served allocation is inadequate to meet performance expectations ('275 Patent, col. 1:45-52).
• The Patented Solution: The invention discloses a scheduling method to manage these competing demands. It prioritizes connections by first allocating bandwidth to meet the "minimum guaranteed rate" for high-priority service classes, and then allocates any remaining or "excess" bandwidth to lower-priority services or to fulfill demands that exceed the minimum guarantees of the high-priority classes ('275 Patent, Abstract; col. 2:36-55). This hierarchical approach is illustrated in the flowchart of Figure 7, which depicts selecting data for a first class of service (608), then a second (616), and subsequently linking and scheduling "excess demand" (626, 630).
• Technical Importance: This type of hierarchical scheduling allows network operators to sell and deliver tiered services with reliable performance for latency-sensitive applications while still making efficient use of all available network capacity for other traffic ('275 Patent, col. 1:16-24; col. 2:1-18).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to "Exemplary '275 Patent Claims" identified in an unprovided exhibit (Compl. ¶11, ¶16). For the purpose of this analysis, independent claim 1 is selected as a representative method claim.
• Independent Claim 1 elements:
  • A method of scheduling data from a plurality of connections for transmission in a frame-based communication system, where the connections are associated with multiple classes of service, comprising the steps of:
  • receiving data from the plurality of connections at a transmitting node;
  • selecting a first data group associated with a first class of service;
  • allocating bandwidth for the first data group to meet a minimum guaranteed data rate;
  • allocating bandwidth for a second data group associated with a second class of service to meet its minimum guaranteed data rate, subject to bandwidth availability after the first allocation;
  • allocating bandwidth for transmitting "excess demand," subject to bandwidth availability after the second allocation; and
  • transmitting the first data group, the second data group, and the excess demand to a receiving node.
• The complaint does not explicitly reserve the right to assert dependent claims, though such a reservation is standard practice.

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused products or services. It refers to them as "Exemplary Defendant Products" which are purportedly identified in charts within "Exhibit 2" (Compl. ¶11, ¶16). However, Exhibit 2 was not filed with the public complaint.

Functionality and Market Context

The complaint provides no details regarding the specific functionality, operation, or market context of the accused instrumentalities. It alleges in a conclusory manner that the accused products "practice the technology claimed by the '275 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant's "Exemplary Defendant Products" infringe the '275 Patent and incorporates by reference claim charts from an unprovided "Exhibit 2" (Compl. ¶16, ¶17). As this exhibit is not available, a detailed claim chart summary cannot be constructed. The narrative infringement theory is that Defendant makes, uses, sells, or imports products that satisfy all elements of the asserted claims (Compl. ¶11, ¶16).

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for analysis of specific claim construction disputes. However, based on the language of representative claim 1, the following terms may become central to the case.

• The Term: "minimum guaranteed data rate"

  • Context and Importance: This term appears in two key allocation steps of claim 1 and defines the threshold for prioritized service. The construction of this term will be critical to determining what level of service commitment the accused system must provide to infringe. Practitioners may focus on this term because the dispute could center on whether it requires a formal, contractual, or protocol-level guarantee (a narrow view) or if it can cover systems with a de facto, priority-based reservation of capacity (a broader view).
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent specification discusses this concept in relation to services like MGR ("Minimum Guaranteed Rate"), which has a "minimum committed rate" that is "guaranteed to be available when requested" ('275 Patent, col. 2:7-12). This language could support an argument that any system functionally reserving a certain amount of bandwidth for a service class meets the limitation.
    • Evidence for a Narrower Interpretation: The use of the word "guaranteed" may support a narrower construction that requires a strict, non-negotiable reservation of bandwidth, as opposed to a mere higher priority in a queuing system. The patent distinguishes services with such guarantees from "excess demand" and "Best Effort" traffic, suggesting a clear demarcation is intended ('275 Patent, col. 2:12-18).

• The Term: "excess demand"

  • Context and Importance: This term defines the third category of traffic to be allocated bandwidth in claim 1. Its definition is important because it dictates what type of "leftover" traffic handling falls within the claim scope.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification defines "excess demand" in one context as demand "greater than the committed rate but less than the peak rate" ('275 Patent, col. 2:12-14) and also discusses linking it with UBR ("User Bit Rate") or "Best Effort" traffic ('275 Patent, col. 17:6-14). This could support a broad reading where any traffic scheduled after guaranteed-rate queues are serviced constitutes "excess demand."
    • Evidence for a Narrower Interpretation: The structure of claim 1 recites a sequence of allocating for two groups with guaranteed rates, and then allocating for "excess demand." This could support an argument that the term is limited to additional requests from the first two service classes that are above their guaranteed minimums, rather than all other lower-priority traffic. The specification provides an example of "grouping excess demand from the first and second classes of service" ('275 Patent, col. 2:50-52), which may support this narrower view.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials" that instruct and encourage end users to operate the accused products in an infringing manner (Compl. ¶14).
• Willful Infringement: The complaint does not use the term "willful." It does, however, plead "Actual Knowledge of Infringement" arising from the service of the complaint itself (Compl. ¶13). The allegation that Defendant "continues to make, use, test, sell, offer for sale, market, and/or import" products despite this knowledge lays a foundation for a claim of post-filing infringement enhancement (Compl. ¶14).

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

• A primary threshold issue will be one of evidentiary sufficiency: As the complaint identifies the accused products and infringement theory only through an unprovided exhibit, a key question is what specific products will be accused and what evidence will be presented to show that they perform the multi-stage scheduling process recited in the patent claims.
• A central legal issue will be one of definitional scope: The case may turn on the construction of "minimum guaranteed data rate". A core question for the court will be whether this term requires a formally configured, explicit bandwidth reservation for a service class, or if it can be construed more broadly to cover any system that functionally prioritizes certain traffic types to consistently achieve a target data rate.
• A key technical question will be one of functional operation: Does the accused system's scheduling logic map to the specific, sequential three-stage allocation process of claim 1 (guaranteed rate group 1, then guaranteed rate group 2, then excess demand), or does it employ a different architecture, such as a single-pass weighted queuing model, that presents a potential mismatch with the claimed method steps?
