RIM Files Two Inter Partes Re-exam Requests over Bluetooth Technologies
On January 25, 2013, Research in Motion (RIM) filed two inter partes re-examination requests for U.S. Patent Nos. 5,515,369 and 6,240,088 related to adaptive frequency hopping for Bluetooth-enabled devices. The requests stem from a January 2012 lawsuit filed by Canadian patent licensing company Wi-LAN against RIM alleging that RIM’s tablets and mobile phones infringe three patents, including the ‘369 and ‘088 patents, and one other U.S. Patent No. 6,232,969. According to the complaint, RIM’s “Bluetooth-Compliant Products,” including the Blackberry PlayBook, Bold, Torch, Curve, Style, Pearl and others, utilize technology that infringes on its patents. Wi-LAN, which has asserted its Bluetooth-technology related patents in over 25 prior suits, currently has 15 active cases against other makers of mobile phones, tablets, and PCs. Judge Patricia A. Seitz of the Southern District of Florida has ordered a Markman hearing to be set for April 2013.
