Taiwan University Sues Apple for Patent Infringement Related to Siri

The National Cheng Kung University, a school based in Taiwan, filed a lawsuit against Apple recently alleging that the Cupertino, California-based firm infringed on a patent owned by the university. Nation Cheng Kung University believes that Apple’s Siri technology, specifically, infringes on two of its patents that cover how a computer interprets, and executes, voice commands.

The patent, granted by the USPTO is titled “Method and system for matching speech data,” and was originally granted on April 27, 2010, according to information obtained by PatentlyApple. “First, the input speech data is segmented into a plurality of input speech frames and the sample speech data is segmented into a matrix, wherein the matching matrix comprises the distance values between each of the input speech frames and each of the sample speech frames,” one patent says. “Next, the distance values are used to calculate a matching score. Finally, the similarity between the input speech data and the sample speech data is determined according to this matching score.” In other words, a user speaks a command, the system recognizes the command and then executes it. A second patent, titled “Speech recognition system,” is also part of the suit.

The complaint was originally filed last Friday, July 27th, in the United States District Court for the Eastern District of Texas.

This isn’t the first time a company has filed a lawsuit alleging that Siri infringes on patented technology. Zhizhen filed a similar lawsuit against Apple in early July.
