A defensive publication, or defensive disclosure, is an intellectual property strategy used to prevent another party from obtaining a patent on a product, apparatus or method for instance. The strategy consists in disclosing an enabling description and/or drawing of the product, apparatus or method so that it enters the public domain and becomes prior art.[1] Therefore, the defensive publication of perhaps otherwise patentable information may work to defeat the novelty of a subsequent patent application.[2] Unintentional defensive publication by incidental disclosure can render intellectual property as prior art.[3]
One reason why companies decide to use defensive publication over patents is cost. In the United States, for example, to obtain a published patent application, one must incur at least filing fee, examination fee, search fees, and early publication fees (currently $530,[when?] minimum plus $300 for early publication), and meet the filing requirements for a proper patent application.
- "The defensive publication route is especially useful for innovations that do not warrant the high costs incurred in patent applications but to which scientists do want to retain access."[4]
