According to the lawsuit, Krisp obtained access to Sanas’s protected data under a non-disclosure agreement (NDA) during discussions of a potential partnership or investment. Instead of pursuing the relationship in good faith, Sanas contends that Krisp used the insights to fast-track its own product, launching a feature that closely mimics Sanas’s accent conversion capabilities.
At the heart of the dispute are four patents held by Sanas covering core methods and systems in voice transformation, machine learning, and accent modulation. Sanas claims that Krisp’s current offerings directly violate these patents. The lawsuit seeks not only injunctive relief to halt further sales and use of Krisp’s product, but also monetary damages and a declaration naming Sanas as a rightful co-inventor of Krisp’s related patents.
This is a case about the theft of innovation. Our company invested years of research and millions of dollars to develop cutting-edge voice AI technology. They cannot allow another entity to profit from our inventions without accountability.
Krisp Technologies, a well-known player in noise cancellation and voice enhancement software, has yet to respond publicly to the complaint. However, legal experts say the case could be a landmark in the AI audio space, setting a precedent for how intellectual property is enforced as real-time voice transformation becomes more mainstream.
The lawsuit is also notable for its timing. The demand for accent-neutral communication tools has surged globally, particularly in customer service, remote work, and digital communication sectors. Both Sanas and Krisp have marketed their solutions as tools to remove linguistic bias and improve user experience — but now, they may face a courtroom showdown instead of a market one.
Filed under Case No. 3:25-cv-05666 and assigned to Judge Thomas Hixson, the legal proceedings could span months or even years, depending on the complexity of evidence and whether a settlement is pursued.
