A new monkey may have to bring a test case to get a definitive answer on whether animals can be “authors” under copyright law. Naruto, the crested macaque from Indonesia, is talking settlement.

People for the Ethical Treatment of Animals, which has been advocating on behalf of the monkey in federal court, on Friday joined photographer David Slater and publisher Blurb in asking the U.S. Court of Appeals for the Ninth Circuit to hold off deciding the celebrated monkey selfie case while they pursue settlement discussions.
