II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,396,886 - "Continuous processing language for real-time data streams," issued March 12, 2013
The Invention Explained
- Problem Addressed: The patent asserts that conventional relational databases are poorly suited for Complex Event Processing (CEP) applications, such as financial trading, which require analysis of high-volume, low-latency data streams. Databases, which store data on disk before querying, create a performance bottleneck, while custom-coded solutions are difficult to scale and maintain (’886 Patent, col. 1:52 - col. 2:51).
- The Patented Solution: The invention is a specialized computer language for expressing queries that operate directly on continuous data streams without first storing the data. This "Continuous Processing Language" is based on a "publish/subscribe" model, where queries subscribe to one or more input data streams and publish results to output data streams, enabling a scalable and efficient architecture for real-time analysis (’886 Patent, Abstract; col. 3:32-52).
- Technical Importance: The patented approach provides a structured, high-performance, and scalable alternative to traditional databases for building applications that must process and analyze massive, fast-moving data streams in real-time (’886 Patent, col. 1:36-44).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1 (Compl. ¶19).
- Essential elements of claim 1 include:
- A computer-implemented method in a continuous processing system.
- Subscribing to one or more continuous input data streams from one or more publishers, where each stream is published in a publisher-specific format via a publisher-specific protocol.
- Executing a query operation directly on the input data streams, without any pre-processing or storing of the streams in any data structure prior to execution.
- Executing the query on a continuous basis.
- Publishing, in real time, a result of the query to one or more output data streams in a subscriber-specific format via a subscriber-specific protocol.
- The publisher-specific communication protocol varies from the subscriber-specific communication protocol.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 8,549,035 - "Operational information providers," issued October 1, 2013
The Invention Explained
- Problem Addressed: In complex Enterprise Service Oriented Architectures (ESOA), applications must access data from numerous, disparate sources. Some data is static (e.g., from a data warehouse), while other "operational data" is dynamic and must be calculated by business processes. Accessing this data is difficult because each source may use a different interface (’035 Patent, col. 1:12-49).
- The Patented Solution: The invention proposes a standardized object called an "operational information provider" (OIP) to act as a unified interface for data retrieval. A front-end application generates a query and sends the OIP to a back-end system. The OIP itself describes the query and specifies the retrieval method, allowing the back-end to execute business operations, retrieve the requested real-time operational data, and return it in a standardized way (’035 Patent, Abstract; col. 2:20-27; FIG. 4).
- Technical Importance: This technology aims to standardize and unify data access within complex, distributed enterprise software systems, simplifying the development of applications that rely on both static and real-time data from varied sources (’035 Patent, col. 1:6-11).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1 (Compl. ¶33).
- Essential elements of claim 1 include:
- At a front-end unit, generating a query for retrieving operational data, including real-time data.
- Sending an operational information provider (OIP) from the front-end to a back-end unit, where the OIP serves as a query interface describing the query and specifying a retrieval method.
- At the back-end unit, receiving the OIP's data request and response operations.
- Executing at least one business operation (including analysis and data mining) at the back-end to generate the requested data.
- Receiving the requested operational data at the front-end unit.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
The accused instrumentality is Defendant's "AlphaX US," a US equity alternative trading system (Compl. ¶13).
Functionality and Market Context
AlphaX US is a trading venue for SEC-registered brokers and dealers (Compl. ¶13). The complaint alleges it operates by relying on access to continuous data streams, such as securities information processor (SIP) feeds, other market data, and active orders (Compl. ¶15). Subscribers can submit orders directly via protocols like Financial Information eXchange (FIX) or a binary protocol (Compl. ¶14). The system also provides real-time information back to participants regarding their orders, executions, and routing preferences (Compl. ¶16). The complaint alleges the system operates on servers and datacenters located in New Jersey (Compl. ¶17).
No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint alleges that infringement is detailed in Appendices A and B, which were not attached to the filed document (Compl. ¶21, ¶35). The following analysis is based on the narrative allegations in the complaint body.
’886 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| subscribing to one or more continuous input data streams from one or more publishers of data streams, wherein each of the one or more continuous input data streams is published in a publisher-specific data representation format via a publisher-specific remote communication protocol | The AlphaX US system allegedly relies on access to continuous data streams such as SIP data feeds and other market data feeds to execute trades. | ¶15 | col. 21:28-34 |
| executing a query operation directly on the one or more continuous input data streams, including any windows of data... without any pre-processing... including without storing the continuous input data streams in any data structure, prior to said executing... | The complaint alleges that AlphaX US executes trades and provides real-time information based on these data streams. The complaint does not provide specific facts regarding the "directly" or "without storing" limitations. | ¶15-16 | col. 21:35-42 |
| publishing, in real time and on a continuous basis, a result of the query operation... in a subscriber-specific data representation format via a subscriber-specific remote communication protocol... wherein the publisher-specific... protocol varies from the subscriber-specific... protocol | The AlphaX US system allegedly provides subscribers with real-time trading information and allows them to connect via specific protocols such as FIX or Binary, which differ from the incoming SIP data feed protocols. | ¶14, 16 | col. 21:43-52 |
- Identified Points of Contention:
- Technical Question: A central factual dispute may concern the negative limitations "without any pre-processing" and "without storing." The complaint alleges this on "information and belief." Discovery will be required to determine if the AlphaX US architecture includes any form of buffering, transformation, or temporary storage that might place it outside the claim's scope.
- Scope Question: The parties may dispute whether the accused system's function of matching trade orders and reporting status constitutes "executing a query operation" as that term is used in the context of the patent's specialized processing language.
’035 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| at a front-end unit, generating a query for retrieving requested operational data, including real-time operational data | Subscribers allegedly generate queries by submitting orders and setting parameters via the AlphaX Hub interface or directly through protocols like FIX. | ¶14, 16 | col. 8:7-9 |
| sending an operational information provider from the front-end unit to the back-end unit, wherein the operational information provider is sent as a query interface to describe the query to identify real-time operational data... and to specify a retrieval method... | An order submitted via the FIX protocol or a parameter change via the AlphaX Hub is alleged to function as the "operational information provider" sent from the subscriber's system to the AlphaX US back-end servers. | ¶14, 17 | col. 8:13-19 |
| executing at least one business operation at the back-end unit, wherein the at least one business operation performs analysis and data mining operations to generate the requested operational data | The AlphaX US back-end system allegedly performs the business operations of trade execution and generates real-time data about orders, executions, and routing preferences in response to subscriber inputs and market data. | ¶15-16 | col. 8:23-28 |
| receiving at the front-end unit from the back-end unit the requested operational data, including the real-time operational data | The system allegedly provides subscribers with real-time information regarding their trading activity. | ¶16 | col. 8:29-32 |
- Identified Points of Contention:
- Scope Question: A primary issue for claim construction may be whether a standard financial message, such as a FIX order, constitutes an "operational information provider" as defined by the patent. Defendant may argue the patent requires a specific, structured object as exemplified by the WSDL description, not just any data packet that requests an action.
- Technical Question: Does the accused system's core function of matching trades based on price and time priority qualify as "analysis and data mining operations"? The defense may argue this term implies more complex business intelligence analytics than the high-speed, rules-based logic of a trading engine.
V. Key Claim Terms for Construction
’886 Patent
- The Term: "executing a query operation directly on the one or more continuous input data streams... without any pre-processing... including without storing the continuous input data streams in any data structure, prior to said executing" (Claim 1)
- Context and Importance: This series of limitations is the technical core of the asserted invention, distinguishing it from conventional databases that must load and store data before processing. The viability of the infringement claim will depend heavily on how narrowly or broadly this "direct, no-storage" processing is defined.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent’s background criticizes systems where a "database stores everything on disk" and contrasts its invention with traditional databases that "implement triggers in a uniformly unscalable and unmanageable way" (’886 Patent, col. 2:8-9, 2:22-24). This context suggests "storing" could be interpreted to mean persistent, on-disk storage, potentially allowing for transient in-memory buffering.
- Evidence for a Narrower Interpretation: The claim language is restrictive, using the absolute terms "without any pre-processing" and "without storing...in any data structure" (’886 Patent, col. 21:38-41). The Abstract also states queries "operate directly on data streams." A defendant may argue this language prohibits even momentary buffering or data format transformations that are common in high-performance systems.
’035 Patent
- The Term: "operational information provider" (Claim 1)
- Context and Importance: Practitioners may focus on this term because the infringement theory depends on casting standard financial messages (like FIX orders) as this claimed entity. The case may turn on whether this term is construed as a functional descriptor or a specific structural object.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim describes the OIP's function: it is "sent as a query interface to describe the query" and "specify a retrieval method" (’035 Patent, col. 8:14-19). A plaintiff could argue that any data object performing this function, regardless of its specific format, meets the definition.
- Evidence for a Narrower Interpretation: The specification introduces the invention in the context of standardizing data access in complex architectures like ESOA and provides a detailed WSDL example of an OIP (’035 Patent, col. 1:6-11; col. 5:14-67). This may support an argument that an OIP is a specific, structured, service-oriented object, not just any generic data packet or protocol message.
VI. Other Allegations
- Indirect Infringement: For both the ’886 and ’035 patents, the complaint alleges induced infringement, stating that Defendant provides "instruction materials, demonstrations, and training services" that encourage customers to use AlphaX US in an infringing manner (Compl. ¶28, ¶42). It also alleges contributory infringement, claiming AlphaX US is "especially made or adapted for use in an infringement" and is not a staple article of commerce suitable for substantial noninfringing use (Compl. ¶30, ¶44).
- Willful Infringement: The complaint alleges willful infringement for both patents based on Defendant’s knowledge of the patents "at least as early as the filing of this Complaint" (Compl. ¶24, ¶38). This frames the willfulness claim as arising from post-suit conduct.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the patents’ specialized terms, such as the "’035 Patent’s" "operational information provider" and the "’886 Patent’s" "query operation," be construed broadly enough to read on the standard functions and communication protocols (e.g., FIX messages, trade execution) of the accused financial trading system?
- A key evidentiary question will be one of technical operation: does the accused AlphaX US system’s architecture align with the "’886 Patent’s" strict requirement for processing data "directly on...data streams...without...storing," or will discovery reveal a fundamental mismatch between the claimed method and the accused system's actual data handling, which may involve some form of buffering or pre-processing?
