Auto-Dril, Inc. v. National Oilwell Varco, L.P. & Canrig Drilling Technology, Ltd.
On April 20, 2018, U.S. District Judge Lee H. Rosenthal entered a Final Judgement in B&L’s clients favor invalidating Auto-Dril’s asserted patent-in-suit (U.S. Patent No. 6,994,172) following a claim construction hearing. Judge Rosenthal found that Auto-Dril’s patent was indefinite (35 U.S.C. § 112, ¶2) for failing to disclose the necessary algorithm to perform the claimed patented steps.
