Patent Trial and Appeal Board Finds All Claims of a Patent Owned by LiquidPower Specialty Products Unpatentable


On November 1, 2017, the Patent Trial and Appeal Board issued the public version of its final written decision in favor of firm client Baker Hughes, a GE Company LLC, finding that all claims of a patent owned by LiquidPower Specialty Products (“LSPI”) are unpatentable on all three grounds asserted in the Baker Hughes petition for inter partes review.

LSPI had sued Baker Hughes in Texas district court alleging infringement of four patents covering drag reducing agents. In response, petitions for inter partes review were filed against all four patents. The PTAB instituted trials on all four petitions, and the three additional trials remain in progress at the PTAB. As a result of the successful institution of inter partes review trials as to all four patents, the district court has stayed its proceedings pending a final resolution of the four PTAB trials.

Baker Hughes was represented by Herbert D. Hart III, George Wheeler, Aaron Barkoff, and Peter Lish.
