If both were created at the same time, it would be a far different court case. I was assuming the case where the logo clearly predates the algorithm, because in that case you would get enough expert witnesses to testify that the logo was itself clean and thus it is extremely likely the algorithm was developed to specifically produce that image given the input. If both were provably independently created at the same time, you would probably instead be having an uproar among scientists about the probability for such an event happening. It may still cause issues because the probability of such an event is so small, that the probability of the proof of their being independently created being wrong is the far more likely event.
