Market seems to be tough for Apple in China as recently, a technology firm has filed a suit against Apple on the charges of patent infringement. The company has claimed that Apple has infringed patent rights by copying its software Siri in its iPhone.

Apple was caught again in the dispute after overcoming its previous dispute in China over the use of name iPad. It paid $60 million for settling down the dispute. Now again, it has caught in the patent dispute over the software Siri.

It has been informed that Siri was first invented in 2004 by Shanghai Zhizhen Network Technology Co Ltd and was patented by the name Xiao i Robot software. However, Apple’s Siri was introduced in 2007. It has come to light that the Chinese version of Siri is similar to that of Apple’s.

Si Weijiang is the lawyer of the firm. Si Weijiang informed that the firm tried to contact Apple two months back but it was all in vain. Si Weijiang said, “We sent legal notices to Apple in May, but no one contacted us. We filed the lawsuit in late June to the Shanghai number one intermediate people's court”.
