As of July 1, 1981, it became possible to request reexamination of already issued US patents. A number of other countries have what are called “opposition procedures” whereby third parties can oppose the patent within a defined time period. For example, a European patent can be opposed within nine months of its granting. The stated objectives of the reexamination laws are to provide an essentially ex parte proceeding, to minimize costs, to maximize the respect of the patent, and to maximize the speed in which a decision is made. It is intended that reexamination would provide assistance to the courts and to the public by giving the patent examiner’s view as to patentability in view of certain newly discovered information uncovered after grant of the patent.
