A computer scientist who created an artificial intelligence system capable of generating original inventions is suing the US Patent and Trademark Office (USPTO) over its decision earlier this year to reject two patent applications which list the algorithmic system, known as DABUS, as the inventor.

The lawsuit is the latest step in an effort by Stephen Thaler and an international group of lawyers and academics to win inventorship rights for non-human AI systems, a prospect that raises fundamental questions about what it means to be creative and also carries potentially paradigm-shifting implications for certain industries.
