Associated Press; UN agency finds US, Asian companies seek most AI patents

"The U.N.’s intellectual property organization says companies in Japan, South Korea and the U.S. are the top filers of patent applications involving artificial intelligence.

The World Intellectual Property Organization has issued a first report aiming to show trends in AI, seen as a growth area in coming years, although still a tiny fraction of all patent applications each year.

WIPO said Thursday that machine learning is the dominant AI technique disclosed in patents."
