Apple asks Chinese court to overturn patent ruling

US technology giant Apple today asked a Beijing court to strike down a patent ruling by state authorities, as it fights an intellectual property battle with a Chinese firm.
Shanghai-based Zhizhen Network Technology has sued Apple for allegedly infringing its Chinese patent with the "intelligent personal assistant" Siri.
Apple representatives had asked China's patent review board, which operates under the State Intellectual Property Office, to declare Zhizhen's original patent invalid.
The body rejected the request, and Apple went to Beijing's Number One Intermediate People's Court seeking a judicial review.
"Our side firmly believe that the ruling by the defendant was based on incorrect facts and laws that were inappropriately referred to," Apple said in its presentation to the court.

"We appeal to the court to revoke the defendant's ruling No. 21307," it said.

Its lawyers told the hearing that Zhizhen's technology was not original enough or innovative enough to deserve a patent.
The proceedings ended this afternoon and the chief of the five-judge panel said the court would send the parties its decision at a later date.
Outside court, Zhizhen's president said there was "nothing new" in Apple's arguments, adding he was not afraid of taking on the US giant.
"Those whose feet are bare do not fear those who wear shoes," Zhu Pinpin said, using a Chinese saying meaning that those who own little have nothing to lose.

Siri, which responds to a user's commands through voice recognition software, made its formal debut with the release of the iPhone 4S in 2011.
Zhizhen says its earlier "Xiao i Robot" product works in a similar way and has wide applications.
Zhizhen's lawyer Yuan Yang complained about the US firm's legal tactics. "It is a consistent strategy of Apple to tirelessly try to make your patent invalid and protract cases as long as possible to pressure you to give in," he said.
