Rock band the Red Hot Chili Peppers are suing a US network over the name of its TV show, Californication.
The Chili Peppers single Californication was released in 2000
The band says the title is "immediately associated in the mind of the consumer" with its 1999 album and single release.
It has filed a lawsuit against Showtime Network - the makers of the TV show, which stars David Duchovny as a writer going through a mid-life crisis.
"For some TV show to come along and steal our identity is not right," said the band's singer, Anthony Kiedis.
He described Californication as "the signature CD, video and song of the band's career".
The legal action seeks a permanent injunction barring Showtime from using the title of the show and "disgorgement of all profits derived by the defendants".
The TV show is a dark comedy featuring graphic sex scenes
It says the programme also features the character, Dani California, which is also the title of a Red Hot Chili Peppers song which was released in 2006.
Tom Kapinos, the show's creator and executive producer, was unavailable for comment.
In July, he told reporters that he first heard the term "Californication" in the state of Oregon.
"Apparently in the 70s there were bumper stickers that said 'Don't Californicate Oregon', because Californians were coming up there, and I just thought it was a great, great title for this show," he said.
