XEC - U.S. Well Services files e-frac patent lawsuit against Halliburton Cimarex

U.S. Well Services ([[USWS]] -9.1%) files a patent infringement lawsuit against Halliburton ([[HAL]] -1.5%) and Cimarex Energy ([[XEC]] -1.6%), alleging they infringed its electric fracking patents.The lawsuit, which seeks unspecified damages and costs, alleges Halliburton's all-electric fracturing fleet violates several U.S. Well Services patents for electric pumps and pumping systems, and monitoring and control systems.The action comes as electric fracking has won greater interest among oil and gas producers seeking to reduce carbon emissions; only a few oilfield service companies own and operate e-frac equipment, including U.S. Well Services.Halliburton CEO Jeff Miller had said the company would be slow to move on the technology because of its cost, but in January, Halliburton said it deployed the industry's first grid-powered fracturing system for Cimarex Energy in the Permian Basin.
