Apple this week filed a lawsuit against Ericsson alleging the Swedish company is asking too high of royalties for use of its LTE technology in Apple’s products. Apple also claims that Ericsson’s LTE patents don’t cover technology essential to standards within the wireless industry, according to Reuters.
Apple asked the United States District Court for Northern California to find that it doesn’t infringe on the patents in question.
Ericsson responded with a suit of its own, filed in the US District Court for Eastern Texas, in order to find if its global licensing agreement with Apple is fair, reasonable, and non-discriminatory.
The legal action comes after two years of negotiations with no new arrangements made. Apple and Ericsson originally entered a patent agreement in 2008 and that has since expired.
“Our goal is to reach a mutually beneficial resolution with Apple. They have been a valued partner for years and we hope to continue that partnership,” Kasim Alfalahi, Chief Intellectual Property Officer at Ericsson, said in a statement.
Ericsson says it pours $5 billion each year into research and development in order to keep growing its patent portfolio. Ericsson claims that every Apple smartphone and tablet with cellular connectivity uses Ericsson technology.
Apple did not immediately respond when reached for comment.
