Waterloo-based Research in Motion is having a roller-coaster day today, and not just because its two co-CEOs have just stepped down. Wi-Lan Inc. has announced it sued RIM for patent infringement in a Florida court on Friday. Wi-Lan, which holds over 3,000 technology patents, claims RIM has infringed two of them, one related to Bluetooth data transmission, the other to a button in the BlackBerry Torch, Bold, and Curve models. Late on Sunday evening, RIM announcedco-CEOs Jim Balsillie and Mike Lazaridis were being replaced by Thorsten Heins, formerly a chief operating officer at the company.
