(Reuters) – Sweden's Ericsson has filed another set of patent infringement cases against Apple in the latest dispute between the two companies over royalty payments for the use of 5G wireless patents in iPhones.
Both companies have already sued each other in the US because Negotiations failed on the renewal of a seven-year telecommunications license agreement, which was first concluded in 2015.
Ericsson did not sue until October, claiming that Apple was wrongly trying to lower royalties while the iPhone maker filed a lawsuit in December accusing the Swedish company of to use "strong arms" to renew patents.
"Because the previous agreement has expired and we have not been able to reach an agreement on the terms and scope of a new license, Apple is now using our technology without a license," he said. a spokesman for Ericsson.
Apple did not immediately respond to a request for comment.
Patent litigation is fairly common among technology companies because each dollar saved can amount to significant amounts during the term of the agreement because companies like Ericsson charge between 2.5 and 5 dollars for each 5G phone.
The Swedish company invests about 5 billion dollars each year in research, has a portfolio of more than 57,000 patents, and royalties from its patent portfolio account for about a third of its operating profit.
Last year, Ericsson settled patent litigation with Samsung after several months of litigation that temporarily affected its quarterly profits. Outstanding fees are usually cleared after a settlement is reached.
