A plaintiff calling itself “Querytron-Heggem LLC” has filed separate lawsuits against Alibaba (2:24-cv-00848) and Fiverr (2:24-cv-00850) in the Eastern District of Texas, as well as a complaint against Redfin (6:24-cv-00558) in the Western District of Texas. All three concern a single patent generally related to refining Internet search results, with infringement allegations targeting the defendants’ platforms, as advertised for facilitating business-to-business (B2B) purchasing. Records in the plaintiff’s identified state of formation apparently do not contain an entity named “Querytron-Heggem LLC” but do contain a “Querytron LLC”.
