Michael Skidmore accused songwriters Jimmy Page and Robert Plant and their publishers of stealing the song's famous opening guitar riff from an instrumental written by the late Randy Wolfe, whose estate he oversees.

A jury ruled the defendants were not liable for infringing the Spirit song Taurus in June (16), and Zeppelin's publishers at Warner/Chappell later requested over $613,000 (£473,000) in attorneys' fees, plus costs.

However, Judge R. Gary Klausner dismissed their bid on Monday (08Aug16), explaining that the legal fees would only have been awarded back to the band's songwriters, record label and other associated companies if the copyright claim against them was frivolous - which Skidmore's was not.

He added there was no evidence that Skidmore "harbored nefarious motives."
