A federal judge has denied Led Zeppelin around £616,242 (800,000 US dollars) in legal fees and other costs in their defence against claims that they stole a riff for the intro to Stairway To Heaven.
Judge R Gary Klausner ruled in Los Angeles federal court that the lawsuit against the band was not frivolous and they were not entitled to recoup their costs.
The trust for the late Randy Wolfe failed to prove that Led Zeppelin's songwriters lifted a passage from an obscure instrumental tune he wrote in the late 1960s.
A jury found guitarist Jimmy Page and singer Robert Plant did not violate Wolfe's copyright to the song Taurus because it wasn't similar enough to Stairway.
Led Zeppelin's lawyers said they deserved legal fees because they won and to deter frivolous litigation.
