The legal team at Qualcomm is gearing up for a battle on multiple fronts. On one hand, the San Diego-based mobile communications group has filed yet another lawsuit Monday against Finland's Nokia with the U.S. International Trade Commission, alleging that the company has violated a number of patents. Over the past eight months, Qualcomm has taken legal action against Nokia a total of three times, and the company had already pressed similar charges against Nokia in Britain.
