In 1996, Bose sued two subsidiaries of Harman International Industries—JBL and Infinity Systems—for violating a Bose patent on elliptical tuning ports on some loudspeaker products. In 2000, the court determined that Harman was to cease using elliptical ports in its products, and Harman was to pay Bose $5.7 million in court costs. Harman stopped using the disputed port design but appealed the financial decision. At the end of 2002, the earlier judgment was upheld but by this time Bose's court expenses had risen to $8 million, all to be paid by Harman.
