Research In Motion (RIMM -9.3%), hammered thanks to bearish comments from Doug Kass and Gene Munster, is also being sued for patent infringement by chipmaker NXP (NASDAQ:NXPI). NXP alleges RIM's phones and tablets infringe patents related to design and data transmission, and is seeking royalties and triple damages. An IP consultant speculates RIM might try to settle quickly to keep the suit from complicating sale talks.
