Sanas asserts the following claims against Krisp in the lawsuit:

• Infringement by Krisp of six of Sanas’ issued United States patents (Patent Nos. 11,948,550, 12,125,496, 12,131,745, 11,715,457, 12,412,561 and 12,417,756);

• Misappropriation of Sanas’ trade secrets in violation of the United States Defend Trade Secrets Act (18 U.S.C. § 1836) and the California Uniform Trade Secrets Act (Cal. Civ. Code § 3426 et seq.) and

• A legal declaration that Sanas is a co-inventor and co-owner of two United States Patents (U.S. Patent Nos. 12,205,609 and 12,223,979) that were improperly issued to Krisp alone, but were based in part on information disclosed by Sanas to Krisp under an NDA—a fact Krisp was obligated, but failed, to disclose to the United States Patent Office.

• Making false and misleading statements concerning Sanas’ accent translation and noise cancellation products in their advertisements and marketing materials, which constitute false advertising in violation of § 43(a) of the Lanham Act, 15 U.S.C. § 1125(a).

Sanas Fights to Keep Free Noise Cancellation Technology

In response to the above-described lawsuit filed by Sanas against Krisp alleging that Krisp infringes multiple Sanas patents, misappropriated Sanas’ trade secrets, improperly filed for patents claiming to be the sole inventor of technology that was actually developed by Sanas engineers, and engaged in false advertising related to the comparison of its products to Sanas’ products, Krisp filed counterclaims against Sanas.  Through its counterclaims, Krisp primarily seeks to force Sanas to pull its free noise cancellation product from the market and to start charging money for it.  In other words, Krisp says Sanas should be liable not because it charges too much—but because it charges too little, in fact, because Sanas charges nothing at all for its noise cancellation product.

But Sanas is fighting back.  On September 29, 2025, Sanas filed a legal motion defending its right to provide its noise cancellation technology to the public for free and seeking to dismiss Krisp’s counterclaims.  More than that, Sanas’ lawsuit against Krisp is about defending fair competition.  Just as Krisp should not be able to steal Sanas’ innovations and sell a knock-off accent translation technology, Krisp should not be able to force the market to pay for noise cancellation technology which was developed at minimal cost, and which meaningfully improves the quality of communication for everyone.

As explained in Sanas’s recent filing:

Sanas.AI Inc. (“Sanas”) brought this case because Krisp Technologies, Inc. (“Krisp”) brazenly misappropriated Sanas’ cutting-edge accent translation machine learning model, claimed inventorship over patents whose purported basis in fact came from Sanas, and engaged in advertising that even Krisp has all but admitted is false.  To deflect from its own clear wrongdoing, Krisp filed counterclaims focused on the California Unfair Practices Act (“UPA”) because Sanas—like Zoom, Microsoft, Krisp, and virtually every other company in the market—allows customers to use its noise cancellation software for free.  In other words, Krisp is suing to force Sanas to charge for something that Sanas (and everyone else) gives away for free.  Under the UPA’s plain text and common sense, Krisp’s UPA claims are legally barred.

When Sanas launched free noise cancellation last year, it said it was in reflection of the company’s “commitment to breaking down communication barriers and enhancing the experience of . . . customers and agents” and to “set a new standard of empowerment in the industry.”  It continued, “[w]e believe that this fundamental tool should be accessible to everyone, which is why we’re offering it for free. This move helps contact centers save on operational costs and ensures that all customer calls are noise-free, stress-free, and cost-free forever.”  Simply put, Sanas believes that everyone has a right to clear communication, and it is willing to fight for that.

Sanas looks forward to defending its position in court.  In the meantime, Sanas’ cutting-edge noise cancellation will remain available to customers for free, as it has promised since day one.
