Taiwan chip designer Elan Microelectronics is suing Apple over the infringement of two US patents.

The company is asking a US court to prohibit Apple from producing, using and selling iPhones, iPod touches and MacBooks, over the patent violation.

The company filed the lawsuit in the US District Court for the Northern District of California, Elan said in a statement to the Taiwan Stock Exchange.

Apple could not immediately be reached for comment.
