TUFTONBORO, N.H. - A small New Hampshire coffee producer that operates out of a barn has prevailed in a trademark infringement case brought by Starbucks over a blend called "Charbucks." "We're just a mom-and-pop little roastery," said Annie Clark, who with her husband, Jim, owns Black Bear Micro Roastery in Tuftonboro. They were sued in 2001 in federal district court in New York by Starbucks, which alleged Black Bear's use of the name "Charbucks" infringed, blurred and tarnished its famous trademarks. Starbucks appealed to the 2nd U.S. Court Circuit Court of Appeals after Black Bear prevailed in district court. The appeals court agreed with the district court in a decision Friday, saying Starbucks didn't prove its case. Charbucks, introduced in 1997, is Black Bear's darkest roast coffee. The appeals court noted that "one of the reasons Black Bear used the term 'Charbucks' was the public perception that Starbucks roasted its beans unusually darkly."
