A federal jury in the Western District of Texas returned a defense verdict on April 17, 2026, finding that Riot Platforms Inc. did not infringe two patents held by Green Revolution Cooling Inc. covering immersion cooling technology used in cryptocurrency mining operations [1]. The case, filed as case number 6:24-cv-00152, proceeded to trial in Waco on claims that Riot's bitcoin mining infrastructure violated U.S. Patent No. 9,992,914 and U.S. Patent No. 10,123,463 [1]. Both patents relate to liquid immersion cooling systems, a method of submerging computing hardware in thermally conductive fluid to manage heat loads at scale.
Green Revolution Cooling, which develops and licenses immersion cooling systems for data centers and high-density computing environments, alleged that Riot's large-scale bitcoin mining operations incorporated the protected technology without authorization [1]. Riot Platforms, one of the larger publicly traded bitcoin mining companies in the United States, denied infringement throughout the litigation. The jury rejected Green Revolution's claims on both patents, clearing Riot of all liability [1].
Because the jury found no infringement, the damages phase was not reached. Green Revolution's potential recovery had been estimated at more than $400 million had the jury found in its favor [1]. That figure made the case one of the higher-stakes patent disputes to reach a Western District of Texas jury in recent years, a court that has remained a preferred venue for patent plaintiffs despite procedural changes that reduced some of its caseload following the Federal Circuit's 2022 decisions on venue.
Post-trial motions or an appeal to the U.S. Court of Appeals for the Federal Circuit remain available to Green Revolution Cooling, and no immediate post-trial filings had been reported at the time of publication [1].
