Research In Motion (NASDAQ: RIMM) has filed a patent cash against Motorola (NYSE: MOT) claiming that the US company infringed on several of its patents. It also alleged that Motorola was trying to collect excess license fees on some of the technology which RIMM uses.
According to The Wall Street Journal "RIM is asking the court to find that Motorola has violated an agreement that it says required it to license those patents on reasonable terms and to determine that Motorola has infringed several of its own patents, including a patent for a mobile device "with a keyboard optimized for use with the thumbs."
Motorola is in the process of deciding whether or not to sell its handset unit. The suit will probably not make that process any easier.
