A Taiwanese university has sued Apple (AAPL) for allegedly infringing upon its voice recognition patents, Reuters reported. Taiwan’s National Cheng Kung University claims the technology found in the iPhone-maker’s Siri voice assistant infringes on two of the school’s U.S. patents dealing with speech recognition technology. The suit was filed on Friday in the United States District Court for the Eastern District of Texas.

“We filed that lawsuit in the Texas court because it processes faster and its rulings are usually in favor of patent owners and the compensations are usually higher,” said Yama Chen, legal manager of National Cheng Kung.

The university is seeking undisclosed damages, although Chen noted that it would be based on Apple’s U.S. sales of devices that incorporate Siri. The school has also asked the court for an injunction on Apple’s use of its voice assistant in the company’s iPhones and iPads.

National Cheng Kung University is currently investigating whether Google (GOOG) and Microsoft ‘s (MSFT) voice-to-text features infringe upon its technology as well.
