Salman Ejaz agreed in 2007 to stop hawking Bose Corp. products intended for sale in the United States on the "gray market" in the European Union. So he turned to reselling Bose items through eBay in Australia, and that landed his attorneys before the U.S. Court of Appeals for the First Circuit on Thursday.

They were there to appeal a finding by U.S. District Judge Denise Casper in Boston on Bose’s trademark claim against Ejaz, an individual eBay reseller. Casper also upheld a clause in a disputed contract between the parties that would entitle Bose to $350,000, based on liquidated damages of $50,000 per item Ejaz sold in violation of the 2007 agreement.
