The Doobie Brothers have filed a trademark lawsuit against The Doobie Decibel System. Billboard reports that the classic rockers are arguing that the duo—which includes Jason Crosby and Moonalice’s Roger McNamee—is using a name that is “confusingly similar” to theirs.

The lawsuit claims that the Doobie Brothers trademarked the words “Doobie Brothers” and “Doobies” for music performance in 1982. The group argues that Doobie Decibel System, is a cover band, is a direct competitor because they play music from same era as the Doobie Brothers. They also say that the duo’s name is “highly phonetically and visually similar” and they note that the word Doobie appears larger than the following Decibal System on the logo and art that the band uses to advertise their concerts. The Doobie Brothers argue that these things constitute proof of “willful intent to trade on the fame and reputation, or to cause confusion, or to cause mistake, or to deceive consumer.”

While The Doobie Brothers do not claim ownership of the word “doobie,” they do say that the word “has no meaning in the music industry other than to identify” them. The band wants Doobie Decibel System to cease using the name immediately, and they are seeking damages for trademark infringement, unfair competition and false designation of origin, as well as an accounting of all earnings for the duo.
