The licensing firm has also sued Apple, HTC and Sierra Wireless' US subsidiary unit over infringing its LTE mobile technology
Patent licensing firm Wi-LAN has filed a patent infringement lawsuit at the Southern District of Florida against BlackBerry maker Research In Motion (RIM) alleging violation of patent relating to its bluetooth technologies.
Wi-LAN, which has licensed its intellectual property to 255 global firms, claims that RIM's PlayBook tablet and several smartphones that include the Bold, Torch, Pearl and Storm, use technology which infringes on its patent.
RIM spokeswoman said: "RIM will vigorously defend itself against patent infringement."
The licensing firm has also launched a series of patent lawsuits at Southern District of Florida against firms including Apple, HTC and Sierra Wireless' US subsidiary unit, over infringing its LTE mobile technology.
In another court in Eastern District of Texas, Wi-LAN has filed a suit against Apple and Sierra Wireless, alleging that firms have infringed its patent related to 3G HSPA handset products.
Wi-Lan had also accused LG of infringing its patent for V-chip technology in March 2012 that allows parents to block inappropriate television content, while the US Court of Appeals for the Federal Circuit (CAFC) has affirmed a lower court's dismissal of a patent infringement lawsuit.
