    Also, according to the complaint, defendant's acts of infringement have been willful, deliberate and in reckless disregard of plaintiff's patent rights.

    CMC claims it has been and continues to be injured and has sustained and will continue to sustain substantial damages as a direct and proximate cause of defendant's acts of patent infringement.

    CMC is seeking a preliminary and permanent injunction, compensatory damages, costs and other general relief the court may deem proper.

  • Cedric R. Emanuel dba Just Wheels vs. SPX Corp./OTC Tools Division

    Plaintiff Cedric Emanuel is a Texas citizen residing in Crosby. He claims he is the inventor and owner of two patents for inventions to replace wheel studs.

    The patents-in-suit are:

  • U.S. Patent No. 6,505,390 issued Jan. 14, 2003, for a Method for Replacing Wheel Studs; and

  • U.S. Patent No. 6,618,920 issued Sept. 16, 2003, for a Wheel Stud Installation Too.

    Plaintiff's business, Just Wheels, is a wheel stud replacement and tire repair service which offers for sale an automotive tool called the Heavy Duty Stud Press, which is used for the removal and/or installation of wheel studs.

    Plaintiff markets the Stud Press and offers it for sale through his Web site

    Upon information and belief, defendant SPX Corporation is in the business of making, distributing, offering for sale and selling – directly through the Internet at its Web site, and through distributors, wholesalers and automotive tools and equipment retailers – various types of truck and automotive specialty tools.

    According to the plaintiff's complaint, the defendant has been marketing and selling the OTC Wheel Stud Remover/Installer Master Kit No. 5195 (OTC-5195) since at least as early as 2007 and continues to market and sell that product to the present time.

    The OTC-5195 Master Kit comes in a storage case and comprises a C-frame/Forcing Screw Assembly, two removing adapters, a receiving cup, a removing pin, an installing adapter and a lube packet. The product comes with instructions for use in both installing and removing wheel studs.

    The plaintiff alleges that defendant has infringed and is continuing to infringe one or more claims of each of the patents-in-suit by offering for sale and selling the OTC-5195 tool, among others.

    As a result of defendant's infringing activities, the plaintiff claims it has been irreparably damaged to an extent not yet determined and will continue to be irreparably damaged by such acts in the future unless the defendant is enjoined by this court.

    The plaintiff also alleges that the defendant has actively induced infringement of one or more claims of the patents-in-suit by offering to sell and selling the OTC-5195 tool.

    Just Wheels is seeking a permanent injunction, compensatory damages, interest, attorneys' fees and other just and proper relief.

    Andy Tindel, Provost Umphrey in Tyler and attorneys from Meredith & Keyhani PLLC in New York, N.Y., are representing the plaintiff.
