A Taiwan-based university has filed suit against Apple for infringing on two speech-recognition patents with its Siri mobile app.
According to the suit, filed in Texas district court, National Cheng Kung University (NCKU) owns the rights to two voice-recognition patents: one for a "method and system for matching speech data" and another for a "speech recognition system."
NCKU claims that all Apple products that include voice-activated assistant capabilities infringe on its patents. At this point, that only includes the iPhone 4S, but Siri is coming to the iPad with the launch of iOS 6 and the feature will likely be included on the next-gen iPhone, rumoured to be making its debut in September.
"As a result of Apple's infringement ... NCKU has suffered monetary damages in an amount not yet determined, and will continue to suffer damages in the future unless Apple's infringing activities are enjoined by this court," NCKU argued.
NCKU said it filed for the first patent in October 2005 and it was issued in April 2010. It filed for the second patent in December 2002 and it was issued in September 2007. Apple acquired Siri in 2010 and introduced the iPhone 4S with Siri in late 2011.
NCKU is asking for a permanent injunction that bans Apple from infringing on its patents, as well as damages and costs.
The lawsuit comes shortly after a Chinese company filed suit against Apple for infringing on one of its patents with Siri. Zhizhen Network Technology sued Apple and Shanghai-based subsidiary Apple Computer Trading for infringing on a patent that covers "a type of instant messaging chat bot system," dubbed Xiaoi Bot, via Siri.
In March, meanwhile, a New York man sued Apple for false advertising regarding Siri.
