Bose Corp., maker of the "Wave" radio, persuaded a federal appeals court to block QSC Audio Products Inc. from registering as a trademark an amplifier system under the "PowerWave" name.
In opposing the Costa Mesa firm's application, Bose said consumers would think the QSC product was made by Bose, which also sells the Acoustic Wave loudspeaker system. The U.S. Patent and Trademark Office's Trademark Trial and Appeal Board had rejected Bose's complaint, saying confusion was unlikely.
Reversing the board's ruling, the U.S. Court of Appeals for the Federal Circuit said the Wave name should be given added protection under trademark laws, because it's famous even when not directly linked to the Bose name.
"We're going to evaluate what our options are," said John Andrews, chief operating officer of QSC. "We don't have any intention of stopping use of the mark."
