Defensive publication is an intellectual property strategy whose aim is to place details of an innovative product or process in the public domain as “non-patent prior art”. The object is to prevent anybody from patenting the innovation in question. By publishing enabling details of a new product or process, the discloser ensures that any subsequent patent application (whether by the discloser himself or a third party) will fail for want of “novelty”.

A defensive publication is used to save the cost of filling and maintaining a patent and at the same time strategically hinder other parties from obtaining a patent for the disclosed invention.
