Why This Matters

Voice AI is rapidly becoming core infrastructure for global communication, powering contact centers, enterprise collaboration, and AI-driven applications. As the market matures, competition has intensified and legal disputes have begun to emerge, which is typical in rapidly developing technology categories. As the technology evolves, performance, reliability, and independent innovation matter.

This page provides factual background about Krisp's technology, its independent development history, and the current litigation so stakeholders can evaluate the facts directly.

Krisp Voice AI Innovation

Krisp develops real-time voice AI technologies that improve the quality and clarity of digital voice communication.

Our work focuses on solving some of the most difficult problems in speech processing, including:

real-time audio processing with extremely low latency

background noise cancellation and voice isolation

accent conversion and speech enhancement technologies

real-time translation and language accessibility

speech intelligence and productivity systems

emotion, age, gender, frustration, music detection systems

Krisp's approach is differentiated by its ability to perform high-quality speech processing in real time with extremely low latency, enabling deployment across live communications environments and supporting millions of conversations every day.

These capabilities require tightly integrated architectures optimized for performance, scalability, and real-world deployment constraints.

These metrics reflect both the scale and reliability of Krisp's technology in real-world, production deployment environments, including in the most regulated industries, where it is independently evaluated and vetted.

Independent Development

Krisp's voice AI technologies have been developed through years of internal research, engineering, and product iteration. The company began work on real-time speech enhancement and noise cancellation technology shortly after its founding in 2017, with patent filings and product releases reflecting early and sustained development in this space.

Krisp's Accent Conversion technology was developed through proprietary internal R&D, with a documented development roadmap reflecting independent internal development prior to any substantive technical discussions with Sanas.

This development history reflects a continuous and independent innovation trajectory across multiple areas of voice AI, including noise cancellation, accent conversion, voice translation, and speech processing systems, supported by internal R&D and proprietary model development. Krisp's patent portfolio, including issued patents for both noise cancellation and accent conversion technologies, reflects the company's investment in original, ground-up engineering.

As Krisp's technology has scaled and the voice AI market has matured, competitive and legal disputes have emerged within the industry as is common in evolving technology markets.

About the Litigation

The litigation between Krisp and Sanas involves competing claims related to certain speech processing technologies. Both companies have asserted claims against the other. Krisp disputes Sanas' allegations in their entirety and maintains that its voice AI technologies were independently developed through years of internal research and engineering. Krisp intends to vigorously protect its innovations and intellectual property through the legal process.

Krisp's Claims Against Sanas

Krisp has filed its own affirmative legal claims against Sanas, asserting that Sanas infringes Krisp's patented noise cancellation technology, a critical foundation for accent conversion, and has engaged in unfair competition practices.

Patent Infringement

Krisp alleges that Sanas infringes Krisp's patented noise cancellation technology (U.S. Patent No. 11,100,941), which Krisp developed and brought to market beginning in 2018, years before Sanas announced a competing noise cancellation offering in August 2024.

Unfair Competition

Krisp alleges that Sanas reproduced aspects of Krisp's patented technology and began offering it at no cost in an effort to divert Krisp's customers. Krisp's unfair competition claims survived Sanas's motion to dismiss and remain active in the case.

Krisp's Defense of Sanas's Allegations

Krisp denies all of Sanas's allegations of patent infringement, trade secret misappropriation, and co-inventorship. Krisp maintains that its voice AI technologies — including its accent conversion technology — were developed independently through Krisp's own research and engineering. The evidence supporting Krisp's position will be presented as the case proceeds.

As with many disputes in emerging technology sectors, the case will proceed through the normal legal process, including discovery, where the evidence and facts will be tested and evaluated in full. Krisp welcomes that process.

Procedural Status of the Case

What the Court Has Decided So Far

To date, the court has issued procedural rulings governing how the case will proceed, but has not made any determinations on the merits.

Some recent communications have suggested that Sanas has "won." That characterization is incorrect. Describing an early procedural ruling as a "win" reflects a misunderstanding of how these cases are decided. The rulings did not resolve any substantive issue.

Discovery is just starting, the court has not evaluated the underlying evidence, and it has not made any findings regarding:

  • the validity of Sanas' patents
  • whether Krisp infringes any patents
  • the accuracy of Sanas' allegations

The case is now in the discovery phase, where both parties will exchange evidence and the factual record will be developed. Future stages may include claim construction proceedings (where the court interprets patent terms), expert analysis, and potentially summary judgment motions and trial.

Krisp is confident in the strength of its technology, its patent portfolio, and the factual record that will emerge through the legal process.

A Note on External Communications

Commitment to Accuracy

Krisp is committed to transparent, factual communication about this litigation. We encourage stakeholders to evaluate the publicly available court filings and to contact us directly with any questions. Some communications circulating about this case have mischaracterized procedural rulings as substantive outcomes. Krisp believes that the facts should speak for themselves and that the legal process will resolve the competing claims based on evidence.
