Back in December 2020, StratosAudio, Inc. filed separate cases against automakers Hyundai, Mazda, Subaru, Volkswagen, and Zhejiang Geely (Volvo). Infringement allegations centered on the provision of vehicle infotainment systems, but the campaign quickly ran into the issue of whether venue could lie in the Western District of Texas based on the presence of and relationships with car dealerships there. In a pair of September 2021 orders, District Judge Alan D. Albright ruled that venue tied to in-district dealerships can be proper, prompting Hyundai and Volkswagen to seek writs of mandamus from the Federal Circuit on the issue (2022-0108, 2022-0109), rulings now awaited in several other litigation campaigns in Texas.
