It's a little more complicated, and I would argue that the court got it wrong, but you cannot patent a gene as it exists and rests in nature. You can patent the cDNA (reverse-transcribed mRNA) genetic code after intron removal, which they argue is not a natural thing, but I think they misunderstood the science, really the triviality of the "invention".
