STOCKHOLM: Swedish mobile telecom gear maker Ericsson is suing Apple Inc for patent infringement after Apple refused Ericsson's offer to have a court determine fair licensing terms, Ericsson said on Friday.

Ericsson said it filed a complaint with the US International Trade Commission (ITC) requesting an exclusion order against Apple's products for infringing Ericsson patents that are essential to the 2G and 4G/LTE standards.

It also filed a second ITC complaint seeking an exclusion order and multiple complaints in the US District Court for the Eastern District of Texas requesting damages and injunctions for infringement of patents "critical to many other aspects of Apple's devices".

Gustav Brismark, head of patent strategy at Ericsson, said Apple's previous licence agreement with Ericsson had expired around mid-January. Ericsson filed a complaint in mid-January against Apple over mobile technology licence payments, responding to a lawsuit from the iPhone maker.

Apple filed its suit on January 12, alleging the LTE wireless technology patents were not essential to industry cellular standards and that Ericsson was demanding excessive royalties.

If the dispute with Apple went Ericsson's way, the US firm would have to pay it between ($250-750 million annually, analysts said after Ericsson's complaint in January, based on estimates of levels of handset sales and royalty payments per phone. Ericsson had IPR revenues of $1.2 billion in 2014.
