James Cameron has won the fifth lawsuit against him for film Avatar in the space of less than two years.
The director of the Oscar-nominated movie was accused by artist William Roger Dean of taking the look of Avatar planet Pandora and its creatures from his artwork.
But according to Variety, US District Court Judge Jesse Furman in New York found there had been no copyright infringement and said that many of the images in the suit were taken from books about Avatar, and not the film itself.
Dean, best known for album cover artwork for bands Yes and Asia, had been seeking 50 million US dollars (£30.6 million) in damages from James, 20th Century Fox and Lightstorm Entertainment.
Previous cases James has also won involved Emil Malik claiming the film infringed his 1998 screenplay Terra Incognita, Bryan Moore saying his screenplays and drawings had been used to create Avatar, and two other claims by Gerald Marowski and Eric Ryder.
The next three Avatar films are set to be made in New Zealand and are expected to be released in December 2016, December 2017 and December 2018.
