This patent infringement litigation, Case No. 2:26-cv-00810, is an active case in the Washington Western District Court, having been transferred from the Texas Western District Court. The plaintiff is Dialect LLC, identified as a Patent Assertion Entity (NPE), also commonly referred to as a patent troll. Dialect LLC's patent acquisition history, involving transfers from an operating company (VoiceBox Technologies Corp., later acquired by Nuance Communications, Inc.) to shell entities like Voice Inventions, LLC and then to Dialect LLC, is indicative of an NPE strategy. The defendant is Meta Platforms Inc., a major technology operating company known for its social media platforms (Facebook, Instagram, WhatsApp) and its ventures into virtual and augmented reality.

The core of the dispute revolves around U.S. Patent No. 8,447,607, titled "Mobile systems and methods of supporting natural language human-machine interactions." This patent generally describes mobile devices equipped with speech and/or non-speech interfaces designed to facilitate natural language interactions between humans and machines. It enables mobile users to submit natural language questions or commands across various domains, with the system presenting responses in a natural manner, leveraging context, prior information, domain-specific knowledge, and individual user profiles to create an intuitive user experience. While the specific accused product is not explicitly detailed in the available public information, given Meta's portfolio and the patent's scope, it is likely that the infringement allegations target Meta's voice-controlled features, AI assistants, or natural language processing capabilities integrated into its various platforms or devices.

The procedural posture shows that the case was initially filed by Dialect LLC against Meta Platforms Inc. in the Texas Western District Court (7:25-cv-00060) on February 7, 2025, before being transferred to the Washington Western District Court as 2:26-cv-00810. The Western District of Washington is notable for having its own Local Patent Rules, which govern the procedures for patent cases. This transfer from the Western District of Texas, a popular venue for patent plaintiffs, to the Western District of Washington, where Meta may have a stronger presence or preferred venue, highlights the strategic considerations in patent litigation regarding forum selection. The case is notable as a classic example of an NPE asserting patents against a large operating technology company, a common trend in the patent litigation landscape, especially concerning broadly applicable technologies like natural language processing.

The patent infringement lawsuit filed by Dialect LLC against Meta Platforms Inc. concerning U.S. Patent No. 8,447,607 has seen several key developments since its initial filing.

Filing & Initial Pleadings

The case was initially filed by Dialect LLC against Meta Platforms Inc. in the Texas Western District Court (Case No. 7:25-cv-00060) on February 7, 2025. On June 9, 2025, Dialect LLC and Meta Platforms, Inc. filed a Joint Notice of Voluntary Dismissal of certain pre-suit indirect and willful infringement claims from the complaint, without prejudice. This allowed Dialect to re-plead these allegations with specificity after fact discovery, if supported by a good faith basis. Meta was granted until June 16, 2025, to respond to Dialect's complaint.

Pre-Trial Motions of Substance

The case was transferred from the Western District of Texas to the Western District of Washington, where it was opened as case number 2:26-cv-00810 on March 2, 2026. This transfer occurred 388 days after the initial filing and before any final merits ruling, damages award, infringement finding, or validity ruling in the Texas court. The case remains active in the Washington Western District Court.

Discovery Milestones

On September 17, 2025, while the case was still in the Western District of Texas, Meta Platforms, Inc. submitted its Preliminary Invalidity Contentions.

Parallel PTAB IPR Proceedings

U.S. Patent No. 8,447,607 has been the subject of multiple Inter Partes Review (IPR) petitions at the Patent Trial and Appeal Board (PTAB):

• IPR2024-00751: Filed by Google LLC against Dialect LLC on April 5, 2024. This IPR was "Not Instituted - Merits" with a termination date of October 11, 2024.
• IPR2025-00656: Filed by Microsoft Corp. against Dialect LLC on March 7, 2025. This IPR was "Not Instituted - Procedural" with a termination date of August 14, 2025.
• IPR2025-01332: Filed by Meta Platforms Inc. against Dialect LLC on July 25, 2025. This IPR was "Not Instituted - Procedural" with a termination date of November 20, 2025.

The fact that all IPRs related to U.S. Patent No. 8,447,607 were not instituted suggests that the PTAB found the petitioners did not meet the threshold for review, which could strengthen Dialect's position in the ongoing district court litigation.

The plaintiff, Dialect LLC, is represented by a team of experienced patent litigators. Based on available information, key counsel include:

• Jonathan K. Waldrop - Lead Counsel

  • Firm: Kasowitz Benson Torres LLP (New York, NY and Silicon Valley, CA office)

He has represented clients like Google, LG, ASUS, Uber, Adobe, and Cox Communications.

  • Firm: Fitch, Even, Tabin & Flannery (and previously Mischcon de Reya New York LLP)
  • Experience: Mark Raskin focuses on intellectual property litigation and licensing matters, with experience in patent, trademark, trade secret, and copyright disputes.

It is important to note that the specific roles (e.g., lead counsel, local counsel) may evolve as the case progresses and can sometimes be inferred from firm locations relative to the court's jurisdiction. John D. Vandenberg's admission in Washington and the firm's Oregon location suggest a local counsel role for Klarquist in the Western District of Washington. Justin Constant and Garland Stephens' presence on correspondence related to the Texas case and IPRs indicate their ongoing involvement. Mark S. Raskin's and Jonathan K. Waldrop's extensive patent litigation backgrounds position them as key players in Dialect's overall litigation strategy.
