Defensive Publication is method to establish prior art by publishing details of an invention into the public domain, with the purpose to stop others obtaining a patent on the same invention. The end goal is to ensure the right to practice the published invention. Studies have revealed that up to two thirds of patenting organisations are using this method actively within their IP strategy. Learn more
