Patent litigation between Motorola and Research In Motion is heating up, with Motorola filing a complaint with the U.S. International Trade Commission.
In the complaint, filed Friday, Motorola alleges that RIM engages in unfair trade practices by importing and selling products that infringe five Motorola patents. The patents cover technologies related to Wi-Fi access, application management, user interface and power management, Motorola said.
The U.S. International Trade Commission has extended an investigation against Nvidia and others until May 26, according to Rambus.
