After scoring a couple of overseas wins, the Artificial Inventor Project has lost its latest bid to force the U.S. Patent and Trademark Office to name artificial intelligence machines as inventors on patents.

“As technology evolves, there may come a time when artificial intelligence reaches a level of sophistication such that it might satisfy accepted meanings of inventorship,” U.S. District Judge Leonie Brinkema of the Eastern District of Virginia wrote in a Sept. 2 opinion. “But that time has not yet arrived, and, if it does, it will be up to Congress to decide how, if at all, it wants to expand the scope of patent law.”
