This will certainly be the crux of intellectual property lawsuits in the future. It's striking that some of these examples have distinct features from specific, identifiable datasets: we can occasionally recognize specific characters (the old man from Pixar's UP is getting mentioned a lot), but it also reproduces more general aesthetic patterns. Even when I can't recognize the source data, I can distinctly see in some of these faces "the Pixar look", and in others "the DreamWorks look". Were I an IP lawyer, I would start thinking of arguments along the lines of "this technology simply obfuscates the source of plagiarisms". I would also start to think about trying to force anyone who uses this technology to disclose the sources of their training data, since a model trained largely on "the Pixar look" could be benefiting from Pixar's character design processes without having to hire any of Pixar's artists. And, if I were philosophically inclined, I would also start thinking about how this is any different from hiring a random artist and instructing them to "design characters that look like Pixar characters". I suspect that one key difference is that the human artist's success can't easily be measured, but the GAN's success can very easily be measured.
