Generative AI, which produces text, images, computer code and even music from existing information, is exploding with more than 50,000 patent applications filed in the past decade, according to the World Intellectual Property Organization (WIPO), which oversees a system for countries to share recognition of patents.

A quarter of them were filed in 2023 alone, it said.

"This is a booming area this is an area that is growing at increasing speed. And it s somewhere that we expect to grow even more," Christopher Harrison, WIPO Patent Analytics Manager, told reporters.

More than 38,000 GenAI inventions were filed by China between 2014-2023 versus 6,276 filed by the United States over the same period, WIPO said.

Harrison said the Chinese patent applications covered a broad area of sectors from autonomous driving to publishing to document management.

South Korea, Japan and India were ranked third, fourth and fifth respectively, with India growing at the fastest rate, the data showed.
