Patent Opposition & Revocation

Patent opposition is a process provided by some patent law systems in which a third party can oppose the grant of a patent in an attempt to prevent (or revoke) the grant of a patent. In the European Patent Office, for example, any person may file opposition to the grant of a European patent during examination of the patent application or within nine months from grant of the patent.
