Stingray IP Solutions LLC v. Amazon Com Inc. et al.

Stingray IP Solutions LLC, a non-practicing entity (NPE) and an entity of Acacia Research Corporation, initiated a patent infringement lawsuit against Amazon.com Inc. and several of its subsidiaries: Immedia Semiconductor LLC (operating as Blink), Ring LLC, Eero LLC, and Amazon Com Services LLC. Amazon.com, Inc. is a multinational technology company known for its e-commerce, cloud computing, digital streaming, and artificial intelligence. Its subsidiaries, Immedia Semiconductor (Blink) and Ring, are prominent in the home security and smart home device market, offering products like security cameras and video doorbells. Eero LLC specializes in wireless mesh networking systems to provide comprehensive home Wi-Fi coverage. The specific accused products or services in this litigation are not detailed in the available public information, but given the defendants' businesses and Stingray IP's portfolio, they likely involve wireless networking technologies. Stingray IP Solutions has a history of asserting wireless networking patents against smart home products.

The asserted patent in this case is US Patent 6958986. A technical sketch of this patent, based on available information, describes an apparatus and method for conducting ultrasonic analysis of slurries, specifically adapted for use in high-temperature and high-pressure environments like autoclave reactors for measuring solid and gas concentrations and particle size distribution. This technical description appears to be incongruous with the smart home and wireless networking technologies typically associated with the defendants. This suggests a potential discrepancy in the provided patent number or its relevance to the accused products, as a direct link between "ultrasonic analysis of slurries" and Amazon's smart home devices or Wi-Fi systems is not immediately apparent from public records.

The case, 2:21-cv-00193, was filed in the U.S. District Court for the Eastern District of Texas and presided over by Judge J. Rodney Gilstrap. The Eastern District of Texas is historically a significant venue for patent infringement litigation, particularly favored by plaintiffs, including NPEs, due to its reputation as a "rocket docket" known for quick adjudication and plaintiff-friendly local rules, judges, and juries. While the Supreme Court's TC Heartland decision in 2017 aimed to restrict venue in patent cases to where the defendant is incorporated or has a regular and established place of business, the Eastern District of Texas, under judges like Judge Gilstrap, has developed a "roadmap" for evaluating what constitutes a "regular and established place of business," potentially allowing many cases to remain in the district. This case is notable due to Stingray IP Solutions' pattern of asserting wireless networking patents as an NPE against operating companies in the Eastern District of Texas, highlighting ongoing trends in patent assertion strategies and venue selection. Stingray IP Solutions is known to monetize wireless networking intellectual property through such assertions.

• Trial Events, Verdict, and Post-Trial Motions: The case did not proceed to trial.

Professor Robert Akl was identified in relation to this specific case, but his role was explicitly noted as "Noninfringement consulting," indicating an expert witness rather than legal counsel.

Based on available information, Fenwick & West LLP represented the defendants, Amazon Com Inc. et al., in Stingray IP Solutions LLC v. Amazon Com Inc. et al. (2:21-cv-00193).

While specific attorneys of record from Fenwick & West LLP for this particular case are not explicitly detailed in the search results, Fenwick & West LLP is identified as the firm that engaged an expert for "noninfringement consulting" for Amazon in this case.

In patent litigation in the Eastern District of Texas, it is common for out-of-state firms like Fenwick & West to work with local counsel. However, the provided search results do not explicitly name local counsel for Amazon in this specific case.

To provide a more comprehensive list, further detailed docket review would be necessary to identify specific attorneys who made appearances. Without direct access to the PACER docket for this specific case, identifying individual attorneys and their precise roles (lead, local, of counsel, in-house) based solely on these search results is not fully possible.

However, broadly, attorneys from Fenwick & West LLP involved in patent litigation for tech companies like Amazon often have extensive experience in intellectual property disputes. For instance, Fenwick & West LLP has represented Amazon in other patent infringement cases, such as TrackThings LLC v. Amazon.com, Inc. et al. in the Western District of Texas.

Given the nature of patent litigation in the Eastern District of Texas, it is highly probable that Amazon was also represented by a local counsel firm from the district, although none are specifically identified in the provided search results for this case.
