Dean had said in his complaint that the similarities between his work and the paintings used in the film were 'substantial, continuing, and direct so as to rule out any accidental copying or similarity in scenes common to the genre' but US District Court Judge disagreed and dismissed the case.
The judge said Dean's allegations were misguided, noting that the images the artist included as evidences were taken from "books about or derived from Avatar," rather than the film, said The Hollywood Reporter.
Since 'Avatar' was released, Cameron has faced multiple copyright infringement lawsuits including the one filed by sci-fi writer Bryant Moore and another by screenwriter Elijah Schkeiban. The Oscar-winning helmer won them all so far.
