VB Assets, LLC v. Amazon.com Services LLC et al.

VB Assets, LLC, a non-practicing entity (NPE) operating as Voicebox Tech, initiated this patent infringement lawsuit against various Amazon entities, including Amazon.com Services LLC, Amazon.com, Inc., and Amazon Web Services, Inc.. VB Assets was formed by former employees and investors of VoiceBox Technologies, an early pioneer in speech recognition and natural language processing technologies that developed voice-control software for companies like Toyota and Chrysler, after its acquisition by Nuance Communications in 2018. The plaintiff's core business revolves around licensing and enforcing its portfolio of patents related to innovations in voice assistants and conversational AI. Amazon, a major operating company, was accused of infringing these patents through its widely popular Alexa virtual assistant and Echo smart speakers.

The litigation, filed in the U.S. District Court for the District of Delaware (Case No. 1:19-cv-01410-MN), was presided over by Judge Maryellen Noreika. Delaware is a prominent venue for patent litigation, particularly following the Supreme Court's TC Heartland decision, which often directs cases to states where corporate defendants are incorporated. The District of Delaware is known for its experienced patent bench and rigorous procedural demands, making it a significant forum for such disputes. Four U.S. Patents were asserted in the trial: US Patent Nos. 8,073,681, 9,626,703, 7,818,176, and 9,269,097. Patent 8,073,681 broadly describes a "system and method for a cooperative conversational voice user interface" that uses shared knowledge to generate user intent hypotheses and adaptive responses. Patent 7,818,176 details a "system and method for selecting and presenting advertisements based on natural language processing of voice-based input". One-line technical sketches for US Patents 9,626,703 and 9,269,097 are not readily available from the provided search results.

This case garnered significant attention due to a jury finding Amazon liable for willful infringement and awarding VB Assets $46.7 million in damages. The lawsuit highlighted allegations that VoiceBox had engaged in discussions with Amazon in 2011 regarding its voice technology, only for Amazon to later launch its Alexa and Echo products, which VoiceBox claimed were "strikingly similar" to its patented technology, and to allegedly poach "dozens" of VoiceBox employees. These factors framed the case as a "David vs. Goliath" battle over intellectual property and talent in the rapidly expanding voice AI market. The litigation also involved arguments related to patent eligibility under Section 101, a frequently litigated area of patent law. Furthermore, VB Assets' recent patent assertions against other major technology companies, including Google and Apple, indicate a consistent and broad strategy to enforce its voice AI patent portfolio.

The patent infringement litigation of VB Assets, LLC v. Amazon.com Services LLC et al. (1:19-cv-01410-MN) in the District of Delaware has progressed through trial and is currently in the appellate phase following a jury verdict. The case involves U.S. Patent 8,073,681, among others, relating to speech recognition and natural language processing in systems like Amazon's Alexa.

Here's a chronological overview of the key legal developments:

1. Filing & Initial Pleadings

• Complaint Filed: VB Assets, LLC initiated the lawsuit against Amazon.com Services LLC and several other Amazon entities on July 29, 2019, alleging patent infringement. The complaint specifically asserted infringement of multiple patents, including U.S. Patent Nos. 8,073,681; 9,626,703; 7,818,176; and 9,269,097.
• Defendants: The defendants included Amazon.com Services LLC, Amazon.com, Inc., Amazon Web Services, Inc., A2Z Development Center, Inc., AMZN Mobile LLC, AMZN Mobile 2 LLC, Rawles LLC, and Amazon Digital Services LLC.

2. Pre-trial Motions of Substance

• The docket indicates various pre-trial activities, including discovery requests and status reports. An omnibus motion hearing was scheduled for August 20, 2020. However, specific outcomes of motions to dismiss, transfer, or stay pending IPR are not explicitly detailed in the provided snippets.
• Mediation efforts were also undertaken, with the parties ordered to jointly hire a mediator by the end of July 2023.

3. Claim Construction (Markman)

• The court issued a Memorandum Order regarding Claim Construction on June 23, 2021, signed by Judge Maryellen Noreika. This indicates that the claim terms of the asserted patents were construed by the court.

4. Discovery Milestones

• The docket shows VB Assets, LLC filed requests for production to Amazon entities in June 2021. Beyond standard discovery, no specific "strategic milestones" are readily apparent from the provided information.

5. Trial Events, Verdict, and Post-Trial Motions

• The case proceeded to a jury trial.
• Jury Verdict: On November 8, 2023, the jury returned a verdict. The jury found that Amazon infringed valid claims of VB Assets' patents and also found the infringement to be willful. Final jury instructions were filed on November 8, 2023.
• Post-Trial Motions: Following the verdict, the parties engaged in post-trial briefing. An oral order dated November 16, 2023, granted the parties' proposed briefing schedule for post-trial motions, with deadlines for opening, answering, and reply briefs extending into January 2024.
• Royalty Rate Adjustment: In January 2025, the court addressed VB Assets' request to increase ongoing royalty rates. The court agreed to increase the rate for infringement of the '681 patent to $0.45 and the rates for the '176 and '097 patents from $0.22 to $0.25, noting increased costs and inflation.

6. Settlement, Dismissal, Judgment, or Appeal

• Judgment: A Judgment Following Jury Verdict was signed by Judge Maryellen Noreika on November 8, 2023.
• Appeal: The case is currently on appeal. Amazon.com Services LLC filed multiple appeals (2025-1113, 2025-1142, 2025-1357) to the Federal Circuit. VB Assets, LLC also filed a cross-appeal.
• Appeal Dismissal (for lack of finality): On March 10, 2025, the Federal Circuit dismissed these initial appeals for lack of jurisdiction, explaining that the district court had not yet entered a "final decision" as some claims (specifically related to U.S. Patent Nos. 8,886,536 and 9,015,049) had not been fully adjudicated or dismissed, preventing a final judgment on all claims for all parties. This suggests the appeal process is pending a truly final judgment from the district court on all asserted claims.

7. Parallel PTAB IPR/PGR Proceedings

• IPR2020-01367 (U.S. Patent 8,073,681): Amazon.com, Inc. and other Amazon entities filed an Inter Partes Review (IPR) petition against U.S. Patent 8,073,681 on July 28, 2020. An IPR Certificate for this proceeding was issued on December 21, 2022. The outcome of this specific IPR regarding institution or final decision on patentability is not explicitly detailed in the provided snippets, beyond the issuance of a certificate.
• Subsequent IPRs: In 2025, [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) and Samsung Electronics America, Inc. filed several IPR petitions against patents owned by VB Assets LLC, including IPR2025-00866 against U.S. Patent 8,073,681 on April 25, 2025. Other IPRs were filed by Amazon.com Services LLC and Samsung against different VB Assets patents, though these were noted as "Not Instituted - Procedural." The existence and outcomes of these later IPRs would potentially influence ongoing or future litigation, though their direct effect on the main district court case's trial verdict for the identified asserted patents is not detailed.

News outlets have extensively covered the patent infringement lawsuit VB Assets, LLC v. Amazon.com Services LLC et al., primarily focusing on the significant jury verdict. In November 2023, a Delaware jury ordered Amazon to pay VB Assets $46.7 million in damages for willfully infringing four of its patents related to speech recognition and natural language processing used in Amazon's Alexa and Echo product range. This verdict was a unanimous decision where the jury found that Amazon had not proven the patents invalid and that the claims were patent eligible. The case was recognized as one of Law.com's "Top 100 Verdicts of 2023".

The lawsuit, filed in 2019, detailed allegations that VoiceBox Technologies, the predecessor to VB Assets, had engaged in discussions with Amazon in 2011 about licensing its voice software. VoiceBox claimed Amazon subsequently launched its Alexa and first-generation Echo products in 2014, which were "strikingly similar" to the technology presented, and accused Amazon of poaching "dozens" of its employees. Analysts noted the significance of the jury's findings on patent eligibility under Section 101, a frequently litigated area of patent law, and highlighted that the jury ultimately found the claims eligible. The court also subsequently increased ongoing royalty rates for continued infringement, with the '681 patent seeing an increase to $0.45 per net new Alexa user and the '176 and '097 patents to $0.25 per net new Alexa shopping user.

However, Amazon's initial appeal to the Federal Circuit was dismissed in March 2025 for lack of jurisdiction, meaning the appellate court did not rule on the merits of infringement or validity. This dismissal, which consolidated three separate appeals, occurred swiftly, leaving the underlying patent claims unresolved and allowing VB Assets' patents to remain enforceable. PatSnap Insights noted that while Amazon avoided a merits adjudication at this appellate stage, the dismissal does not extinguish VB Assets' patents or bar future enforcement if the jurisdictional defect is corrected. A second complaint was also filed by VB Assets against Amazon in July 2024, alleging infringement of five more natural language processing patents, further indicating ongoing litigation efforts by VB Assets related to its voice AI portfolio.
