The patent document itself and the Unified Patents search results do not directly provide plaintiff and defendant for this district court case. The snippet from the patent text says "US case filed in Texas Eastern District Court" and links to https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/4%3A25-cv-00200.
