  • Whipstock Services Inc. vs. Key Energy Services Inc.

    Whipstock, a Baytown-based corporation, claims to have the rights to U.S. Patent No. 5,769,166. The '166 Patent was issued June 23, 1998 to inventor John Duke for a Wellbore Window Milling Method. Duke assigned the patent to Whipstock on May 24, 2004.

    The plaintiff alleges that Key Energy had actual notice of the '166 Patent and has been and is now infringing on claims of the patent without Whipstock's consent. Specifically, the original complaint states, Key Energy is using, offering for sale or selling a method that provides whipstock and milling services covered by the '166 Patent.

    Whipstock Services is seeking actual damages in an amount no less than reasonable royalty. Because the plaintiff believes that Key Energy's infringement is willful, Whipstock claims it is entitled to enhanced damages in an amount equal to treble the actual damages.

    The plaintiff is asking for a permanent injunction and for the court to schedule a Markman hearing regarding interpretation of the scope of the claims of the '166 Patent.

    Whipstock wants Key Energy to account for all sales, revenues and profits derived from the infringement and is seeking attorney fees and other relief as may be just and appropriate.

    Guy Matthews of Matthews, Lawson, Bowick PLLC in Houston is lead attorney for the plaintiffs with assistance from Andy Tindal of Provost Umphrey Law Firm LLP-Tyler Office.

    The case has been assigned to U.S. District Judge Leonard E. Davis.
