Case Timeline

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

U.S. Patent No. 8,856,221 - System and Method for Storing Broadcast Content in a Cloud-Based Computing Environment, issued October 7, 2014

The Invention Explained

• Problem Addressed: The patent describes a need for an on-demand media storage and streaming system that tailors costs to individual consumer needs, moving away from flat-rate subscription models or per-video fees that do not account for the content's duration or the consumer's actual usage patterns (’221 Patent, col. 2:12-18). It also notes the problem of consumers wanting to stream content that may not be currently stored on a provider's server, leading to fulfillment delays (’221 Patent, col. 2:3-12).
• The Patented Solution: The invention proposes a server-based system that receives and distinguishes between two types of user requests: a "storage request" to download and save specific media content for a designated period, and a "content request" to stream or access previously stored media (’221 Patent, FIG. 2; col. 5:21-36). The system first authenticates the user, processes the request type, verifies content availability for storage requests, and initiates delivery for content requests, creating a more flexible, user-driven storage and retrieval architecture (’221 Patent, col. 5:1-6:5).
• Technical Importance: This approach allows for a system where cloud storage resources are allocated based on explicit user requests for specific content and storage durations, potentially enabling more granular, usage-based pricing models (’221 Patent, col. 2:28-33).

Key Claims at a Glance

• The complaint asserts at least independent claim 7 of the ’221 Patent (Compl. ¶15).
• Independent Claim 7 recites a method with the following essential elements:
  • Receiving a request message including media data indicating requested media content and a consumer device identifier.
  • Determining whether the consumer device identifier corresponds to a registered consumer device.
  • If the user is registered, determining whether the request is a "storage request message" or a "content request message."
  • If it is a storage request, determining whether the requested media content is available for storage.
  • If it is a content request, initiating delivery of the requested media content to the consumer device.
• The complaint does not explicitly reserve the right to assert dependent claims but states infringement of "one or more claims, including at least Claim 7" (Compl. ¶15).

III. The Accused Instrumentality

Product Identification

• The Agora Cloud Recording platform and any similar products (Compl. ¶17).

Functionality and Market Context

• The complaint alleges the Accused Product is a component for developers to "record and save voice calls, video calls, and interactive streaming on your cloud storage" (Compl. ¶19, p. 4). A key feature highlighted is the ability for a user to "either attend an online course at the time of the course or watch the recorded course later" (Compl. ¶19, p. 4).
• The platform is alleged to require configuration of cloud storage buckets, use of user credentials for access, and generation of playlists (M3U8 files) to enable online playback of recorded content (Compl. ¶19, p. 4; Compl. ¶22, p. 6). The complaint includes a screenshot of a login page, suggesting a user authentication mechanism is part of the system (Compl. ¶20, p. 5).

IV. Analysis of Infringement Allegations

’221 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: Claim 7 recites distinct "storage request message" and "content request message" types. A central question will be whether the Accused Product's API calls or user interactions can be technically mapped to these two specific, distinguished message types as required by the claim's logic, or if the product uses a more unified or different request architecture.
  • Technical Questions: The complaint alleges the product "necessarily" performs several claimed steps (e.g., determining the request type) but provides limited detail on the underlying technical mechanism. For instance, the screenshot of a login page demonstrates an authentication function, but a key question for the court will be what evidence shows the system subsequently performs the specific branching logic of distinguishing between a "storage request" and a "content request" as separate determinations. (Compl. ¶20, p. 5).

V. Key Claim Terms for Construction

• The Term: "storage request message" / "content request message"
• Context and Importance: The entire logical flow of independent claim 7 depends on the system's ability to distinguish between these two message types. The definition of these terms and the evidentiary standard for proving the Accused Product makes this specific determination will be critical to the infringement analysis. Practitioners may focus on whether these terms require two structurally distinct message formats or can be met by a single message type with a flag or parameter indicating the user's intent.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent does not appear to define a rigid structure for these messages. One could argue that any message that results in the system performing a storage action is a "storage request message," and any message that results in a streaming action is a "content request message," regardless of their format. The specification refers to them based on their function, for example, a "storage request message may include media data indicating the consumer device is requesting that remote server 16 store specific media content" (’221 Patent, col. 5:22-26).
  • Evidence for a Narrower Interpretation: The flowchart in FIG. 2 depicts "Storage Request Message Received?" (S106) and "Content Request Message Received?" (S124) as two separate decision blocks. This could support an argument that the invention requires two distinct and separately identifiable message types that the system must check for sequentially or in parallel, not merely a single request type with a data field indicating intent.

VI. Other Allegations

• Indirect Infringement: The complaint does not contain specific allegations of indirect infringement (inducement or contributory).
• Willful Infringement: The complaint alleges knowledge of infringement "at least as of the service of the present complaint" (Compl. ¶14), which may form the basis for a post-filing willfulness claim but does not allege pre-suit knowledge.

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

• A core issue will be one of evidentiary sufficiency: The complaint makes several conclusory allegations that the accused product "necessarily determines" or "verifies" certain conditions. A key question will be whether discovery reveals specific, identifiable processes within the Agora Cloud Recording platform that map directly onto the distinct logical steps of authenticating a user, separately identifying a request as one for "storage" versus "content," and then performing the separate availability or delivery actions required by Claim 7.
• A second central issue will be one of claim construction: The case will likely turn on whether the terms "storage request message" and "content request message" can be construed broadly to cover any API call that results in a storage or streaming action, or if they will be construed more narrowly to require distinct, formally separate message types that the system must explicitly differentiate as shown in the patent's flowcharts. The outcome of this construction may determine whether the accused system's architecture falls within the scope of the claims.
