The U.S. Patent and Trademark Office and the South Korean Intellectual Property Office are expanding cooperation in patent classification activities, they said in a news release Thursday (http://1.usa.gov/1kGlqxy).

PTO said the change will make it easier to find existing South Korean patents and apply for new patents in South Korea.
