----------------------------
United States copyright regulators are agreeing with Wikipedia's conclusion that a monkey's selfie cannot be copyrighted by a nature photographer whose camera was swiped by the ape in the jungle. The animal's selfie went viral.
The US Copyright Office, in a 1,222-page report discussing federal copyright law, said that a "photograph taken by a monkey" is unprotected intellectual property.
Wikipedia says the public, not the photojournalist, owns the rights to ape's pic.
"The Office will not register works produced by nature, animals, or plants. Likewise, the Office cannot register a work purportedly created by divine or supernatural beings, although the Office may register a work where the application or the deposit copy state that the work was inspired by a divine spirit," said the draft report, "Compendium of US Copyright Office Practices, Third Edition."

Personally, I think the monkey should get paid....
