NBCNews - "Led Zeppelin prevailed in a long-running copyright dispute after the 9th U.S. Circuit Court of Appeals upheld a jury verdict saying the rock band's 1971 megahit "Stairway to Heaven" did not illegally borrow from Spirit's 1968 track "Taurus." "The trial and appeal process has been a long climb up the 'Stairway to Heaven,'" read the judges' opinion, which was filed Monday and affirmed "that Led Zeppelin's 'Stairway to Heaven' did not infringe Spirit's 'Taurus.'" The copyright battle dates to 2014, when the estate of Spirit guitarist Randy Wolfe sued Led Zeppelin, alleging copyright infringement. [...] A jury ruled against the estate two years later, after which attorneys for the estate sought a new trial. In 2018, a three-judge panel of the 9th Circuit Court ruled in favor of the estate. In response, Led Zeppelin's attorneys sought a rehearing before the full 9th Circuit, which heard the case in September."
