Though apparently not when it comes to suing for copyright infringement.  Earlier this week, the Ninth Circuit issued a ruling in a case involving photographs taken by a monkey on a camera left unattended by a nature photographer in Indonesia—aptly deemed the “Monkey Selfies.”  The copyright infringement case was filed by People for the Ethical Treatment of Animals, Inc. (PETA) as “Next Friends” of the monkey named Naruto against the photographer and entity that published the Monkey Selfies in a book that identified themselves as the copyright owners (although also noting that Naruto took the photographs).  After a lengthy dispute, the Ninth Circuit affirmed the district court’s ruling and held that animals like Naruto cannot sue for copyright infringement because, as nonhumans, they lack the required standing under the Copyright Act, which does not expressly authorize animals to sue.
