Internet auction site EBay has blocked retailer Perfumebay.com from using a Web site address ending with "ebay" after an appeals court ruled it was trademark infringement. Perfumebay, a seller of designer perfumes over the Internet, now is no longer able use the domain name "Perfumebay.com" because the presence of "ebay" in the address confuses consumers, a federal appeals court ruled Monday in Pasadena. San Jose-based eBay had earlier accused Huntington Beach-based Perfumebay of redirecting customers who did Internet searches for "Perfume eBay." Ultimately, the court rejected Perfumebay"s argument that the terms weren"t alike; "perfumebay.com" still goes to the company"s website but it looks like the company will soon need to find a new digital home.
