Michael Skidmore, a trustee for the late Spirit guitarist Randy California, has lodged the appeal against the decision after the rockers were found not guilty of stealing part of their classic song from Spirit's 'Taurus' last month.
According to The Wrap, the notice read: "Please take notice that Plaintiff Michael Skidmore, Trustee for the Randy Craig Wolfe Trust, hereby appeals to the United States Court of Appeals for the Ninth Circuit from the final judgment entered on June 23, 2016, as well as any and all interlocutory rulings, decisions, and orders that gave rise to the judgment and are merged therein."
Skidmore's lawyer Francis Malofiy insists there are "many appealable issues".
Last month, the jury found Led Zeppelin did have access to 'Taurus', but it was decided the songs are not substantially similar.
The group - which was comprised of Jimmy Page, Robert Plant, John Paul Jones and the late John Bonham - were accused of lifting the music from the 1968 instrumental track for their own song, which they co-wrote and released in 1971.
However, Jimmy denied allegations that he and Robert penned the classic rock song after hearing 'Taurus'.
He said in court: "Something like that would stick in my mind. It was totally alien to me."
Page admitted he owned three Spirit albums and that Led Zeppelin used a riff from another of the band's track in a medley played during their first tour of Scandinavia.
