A work of art created by artificial intelligence without any human input cannot be copyrighted under United States law, a U.S. court in Washington has ruled.

Only works with human authors can receive copyrights, U.S. District Judge Beryl Howell said on Friday, affirming the U.S. Copyright Office's rejection of an application filed by computer scientist Stephen Thaler on behalf of his DABUS system.

The Friday decision follows losses for Thaler on bids for U.S. patents covering inventions he said were created by DABUS, short for Device for the Autonomous Bootstrapping of Unified Sentience.
