The U.S. International Trade Commission has decided to investigate Apple after two complaints from Ericsson that the iPhone maker violated its patents.
The companies have been fighting since the start of the year when a license agreement covering Apple’s use of Ericsson patents on LTE high-speed wireless technology expired. Apple complained that Ericsson had asked too much money for the patents during negotiations.
Apple sued Ericsson in January, arguing the patents are not essential for LTE technology and that the price was excessive. Ericsson counter-sued two days later, alleging Apple had infringed the patents and that the price was fair, reasonable and non-discriminatory—the requirement for patents used in industry standards.
