インディアナポリス・モーター・スピードウェイ
In 1996, Indianapolis Motor Speedway President Tony George launched a new national championship racing series, the USAC sanctioned Indy Racing League. This resulted in a legal battle over the "IndyCar" trademark: In March 1996, CART filed a lawsuit against the Indianapolis Motor Speedway in an effort to protect their license to the "IndyCar" mark after the Indianapolis Motor Speedway had attempted to terminate it. In April, the Indianapolis Motor Speedway filed a separate lawsuit against CART to prevent them from further use of the mark.
