Kim & Chang’s Intellectual Property Practice successfully represented Pharmbio Korea Inc. (“Pharmbio Korea”), a domestic pharmaceutical company, in two patent invalidation lawsuits related to bowel cleanser tablets. The team secured victories at both the Intellectual Property Trial and Appeal Board (the “IPTAB”) and the Intellectual Property High Court (the “IP High Court”) by demonstrating that the two patents in question (the “Subject Patents”) could not have been easily developed by a person of ordinary skill in the art based on the prior art inventions.
