It seems The Doobie Brothers really do take the band name quite seriously, case in point: the band is suing the group The Doobie Decibel System over trademark usage claiming the band’s name is “confusingly similar” to theirs, according to Billboard.

On Friday, Doobie Brothers Corp. and Doobro Entertainment sued the Northern California folk-rock cover duo-which consists of musicians Jason Crosby and Roger McNamee. The band said it successfully trademarked the words “Doobie Brothers” and “Doobies” for musical performances in 1982.

The band is arguing that Crosby and McNamee’s use of “Doobie” in their band’s name exhibits “willful intent to trade on the fame and reputation, or to cause confusion, or to cause mistake, or to deceive consumers.” They want the group to stop using the name DDS immediately and are seeking punitive damages for trademark infringement, false designation of origin and unfair competition. They also are requesting a full accounting of the group’s earnings.

Crosby and McNamee are far from novice musicians. Crosby has played with Bob Weir, Eric Clapton and Carlos Santana while McNamee performs in the jam band, Moonshine and is the co-founder of prominent venture capital firms Silver Lake Partners and Elevation Partners, the latter he founded with U2‘s Bono.
