  • Wi-Lan Inc. vs. Research In Motion Corp. et al

    Plaintiff Wi-Lan, a Canadian corporation, claims to own the rights to U.S. Patent Nos. RE37,802 and 5,282,222.

    The '802 Patent was issued July 23, 2002, for a Multicode Direct Sequence Spread Spectrum.

    The '222 Patent was issued Jan. 25, 1994, for a Method and Apparatus for Multiple Access Between Tranceivers in Wireless Communications Using OFDM Spread Spectrum.

    Wi-Lan alleges that defendants Research In Motion Corp., Research In Motion Ltd., Motorola Inc. and UTStarcom have infringed the '802 and '222 Patents by making, using, importing or selling mobile handsets and/or other products compliant with the CDMA2000 standards or the 802.11 standards.

    "Wi-Lan has no adequate remedy at law against defendants' acts of infringement, and unless defendants are enjoined from their infringement of the '802 Patent and the '222 Patent, Wi-Lan will suffer irreparable harm," the original complaint states.

    The plaintiff also alleges that defendants had knowledge of the '802 and '222 Patents, but "have not ceased their infringing activities" which are willful and deliberate.

    Wi-Lan is seeking a permanent injunction against defendants, compensatory damages, treble damages for willful infringement, attorneys' fees, costs, interest and other relief to which it may be entitled.

    Sam Baxter of McKool Smith PC in Marshall is lead attorney for the plaintiff.
