Cerence Files Patent Infringement Suit Against Apple Over Text and Voice Recognition Technologies

Cerence has filed a patent infringement lawsuit against Apple in the US District Court for the Western District of Texas. The lawsuit covers certain Cerence technologies, including text input and recognition, and voice. Cerence is a provider of AI and machine learning technologies for the automotive and IoT industries.

Cerence, a leading provider of AI and machine learning technologies for the automotive and IoT industries, has filed a patent infringement lawsuit against Apple in the US District Court for the Western District of Texas. The lawsuit, which was announced on September 4, 2025, alleges that Apple has infringed on several of Cerence's patents related to text input and recognition, as well as voice command recognition [1].

Cerence, which has a portfolio of patents developed over decades of research and development, claims that Apple has infringed on its intellectual property rights. The company has not revealed specific details about which patents are central to the lawsuit, but it is believed to be related to Apple's voice assistant, Siri, and possibly CarPlay [1].

Cerence's lawsuit is not the first time Apple has been sued over voice recognition technology. In the past, Apple has faced similar legal battles, including a dispute over the Apple Watch blood oxygen sensor [1]. However, the specifics of this new lawsuit remain unclear, and it is difficult to ascertain the validity of Cerence's claims without knowing the key patented technology at issue.

The lawsuit comes at a time when Cerence is experiencing strong financial performance. The company reported robust Q3 FY2025 results, exceeding guidance with revenue of $62.2 million and Adjusted EBITDA of $9.0 million [2]. Cerence expects revenue between $53-58 million for Q4 FY2025, maintaining a strong market position with its AI technology serving 52% of worldwide auto production [2].

The legal action highlights the growing importance of intellectual property in the tech industry, particularly in the realm of AI and conversational interfaces. As companies continue to innovate and develop new technologies, the protection and enforcement of patents will remain a critical aspect of business strategy.

Apple is expected to respond to the lawsuit, and a lengthy court battle may follow. The outcome of this dispute could have significant implications for both companies and the broader tech industry.
