II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,615,233 - "Apparatus and Method for Transmitting Documents Between a Server Computer and a Client Computer"
- Patent Identification: U.S. Patent No. 6,615,233, "Apparatus and Method for Transmitting Documents Between a Server Computer and a Client Computer," issued September 2, 2003.
The Invention Explained
- Problem Addressed: The patent’s background section describes the then-current process for testing web browser and server software as involving the manual and repetitive downloading of numerous web pages, a process noted to be costly and time-consuming (’233 Patent, col. 2:37-52).
- The Patented Solution: The invention proposes a system to automate this process. A server maintains a "document list" of document identifiers (e.g., URLs). Upon receiving an initial download request from a client, the server sends the first document from the list and also embeds a "controller" within it. This controller, exemplified by a "META REFRESH" tag, automatically commands the client computer to make a subsequent download request after a predetermined time, thus triggering the download of the next document in the sequence without further manual user action (’233 Patent, Abstract; col. 3:1-17).
- Technical Importance: This method provided a way to automate sequences of data transmission in a client-server environment, which could reduce the manual labor and associated costs of software testing and other repetitive download tasks (’233 Patent, col. 2:48-52).
Key Claims at a Glance
- The complaint alleges infringement of "one or more claims" but does not identify any specific claims, either independent or dependent (Compl. ¶8).
- An Inter Partes Review Certificate (IPR2015-00732) indicates that claims 1-3, 6-13, 15-17, 27, 31, 49, and 59 have been cancelled. This includes several key independent apparatus and method claims.
- For illustrative purposes, the elements of the now-cancelled independent apparatus Claim 1 are:
- an input that receives download request messages from the client computer;
- a selector that, in response to receipt of a download request message, selects one of the set of documents based upon information not in the download request, the download request message including no address information identifying the selected one of the set of documents;
- an output that forwards both a controller and the selected one of the set of documents to the client computer;
- wherein the controller, when executing on the client, commands the client computer to generate and transmit a subsequent download request to the server.
III. The Accused Instrumentality
Product Identification
- The complaint identifies "Apple iCloud" as an infringing product/service (Compl. ¶8).
Functionality and Market Context
- The complaint describes the accused instrumentality only as "online storage and synchronization products/services" (Compl. ¶8). No specific technical details regarding the operation of iCloud's synchronization protocols, data handling, or client-server communication methods are provided in the complaint.
IV. Analysis of Infringement Allegations
The complaint alleges direct infringement but provides no specific factual basis, claim chart, or mapping of any claim elements to the features of Apple iCloud (Compl. ¶¶8-9). The analysis below is therefore a hypothetical construction of potential infringement theories based on the patent's disclosure and the general nature of the accused service.
No probative visual evidence provided in complaint.
’233 Patent Infringement Allegations (Illustrative, based on cancelled Claim 1)
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a selector that...selects one of the set of documents based upon information not in the download request... | The complaint does not detail this functionality. A potential theory may be that an iCloud server selects a file to synchronize to a client device based on a server-side list of pending updates. | ¶8 | col. 7:3-9 |
| the download request message including no address information identifying the selected one of the set of documents | The complaint does not detail this functionality. A potential theory may be that a client's "sync" request is a generic request, not one for a specific, user-selected file. | ¶8 | col. 7:7-9 |
| an output that forwards both a controller and the selected one of the set of documents to the client computer | The complaint does not detail this functionality. A potential theory may be that in transmitting a synced file, the iCloud server also sends a command or data that controls subsequent sync behavior. | ¶8 | col. 7:10-12 |
| ...the controller commanding the client computer to generate and transmit a download request message to the server computer. | The complaint does not detail this functionality. A potential theory may be that the aforementioned command from the server instructs the client device to automatically request the next file or update. | ¶8 | col. 7:12-14 |
- Identified Points of Contention:
- Evidentiary Questions: The central issue is the complete lack of factual allegations in the complaint. Plaintiff would need to present evidence demonstrating that iCloud's synchronization protocol operates using the specific server-driven, controller-based mechanism claimed in the patent, as opposed to more common client-polling or push-notification models.
- Scope Questions: A potential dispute may arise over whether the term "document," which the patent describes in the context of a "web page," can be interpreted to read on the arbitrary user files and data managed by a cloud storage service like iCloud (’233 Patent, col. 2:24-27).
- Technical Questions: A key technical question is whether iCloud's synchronization architecture includes a "controller" sent from the server that "commands" the client to make a subsequent request, as required by the claims. The defense may argue that modern sync clients operate with more autonomy, managing their own state and initiating requests independently, which may not align with the claimed invention.
V. Key Claim Terms for Construction
Because the complaint asserts no specific claims and provides no infringement theory, the following analysis identifies terms from the illustrative (and cancelled) Claim 1 that would likely be central to the dispute.
The Term: "controller"
Context and Importance: The definition of "controller" is fundamental to the claim, as it is the mechanism that automates the download sequence. The dispute would hinge on what technical structures meet this definition. Practitioners may focus on this term because its scope determines whether the claim is limited to simple web-page refresh mechanisms or can cover modern, complex software protocols.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests the controller is not limited to a single embodiment, stating that "a Java applet may be...utilized" or it could be an "independent, freely operating program" on the client computer (’233 Patent, col. 5:24-31).
- Evidence for a Narrower Interpretation: The patent's most prominent and detailed example of a controller is the "META REFRESH tag," a specific HTML feature (’233 Patent, col. 3:5-6; col. 4:46-56). A party could argue the invention is centered on this web-specific technology.
The Term: "download request message including no address information identifying the selected one of the set of documents"
Context and Importance: This limitation defines the nature of the client's automated request, distinguishing it from a standard request for a specific, known resource. Infringement requires the client request to be generic. Practitioners may focus on this term to distinguish between a user-directed file download and an automated, system-level "check for updates" message.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: This language could be argued to cover any generic "sync" or "update" request that does not specify a file by name or path, but instead asks the server to determine what, if anything, to send next.
- Evidence for a Narrower Interpretation: The specification describes an embodiment where the client is directed to request the "control script" itself, which is a specific target, rather than a file from the document list. A party could argue the "download request message" must be a request for this specific type of intermediary script, not simply a generic "sync" command (’233 Patent, col. 4:63-66).
VI. Other Allegations
The complaint does not provide sufficient detail for analysis of indirect or willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
- Case Viability Post-IPR: The primary and potentially dispositive question is one of claim survival. Given the IPR certificate cancelling a significant number of claims, including multiple independent claims, the case may turn on whether any asserted (or assertable) valid claims remain that are broad enough to read on the accused technology.
- Evidentiary Sufficiency: Assuming a valid claim remains, a key question will be one of factual proof. Can the Plaintiff produce evidence to show that Apple's iCloud service—a modern cloud synchronization platform—actually operates using the specific, sequential, "controller"-driven architecture described in a patent from the late 1990s, or is there a fundamental mismatch in technical operation?
- Definitional Scope: The case may hinge on a question of claim construction: can the term "controller," rooted in the patent's examples of a "META REFRESH" tag, be construed to cover the sophisticated, state-aware communication protocols likely used by a modern cloud service, or is the technology accused simply outside the scope of the patented invention?
