  • Wi-Lan Inc. vs. Conexant Systems Inc.

    Plaintiff Wi-Lan claims to be the owner by assignment of U.S. Patent No. 5,956,323 issued Sept. 21, 1999, for a Power Conservation for POTS and Modulated Data Transmission.

    Wi-Lan alleges defendant Conexant has infringed, directly and indirectly the '323 Patent by making, using or selling Digital Subscriber Line (DSL) products compliant with the ITU G.992 and/or G.993 standards that fall within the scope of at least one claim of the patent.

    "Wi-Lan has no adequate remedy at law against Defendant's acts of infringement and, unless Defendant is enjoined from its infringement of the Patent-in-Suit, Wi-Lan will suffer irreparable harm," the complaint states. "Defendant had knowledge of the Patent-in-Suit and did not cease its infringing activities. Defendant's infringement of the Patent-in-Suit has been willful and deliberate."

    The plaintiff is seeking a permanent injunction, compensatory damages, treble damages, costs, attorneys' fees, interest and other relief to which it may be entitled.

    Sam Baxter of McKool Smith PC in Marshall is representing the plaintiff.

    The case has been assigned to U.S. District Judge T. John Ward.
