Validity

In most systems, a patent is valid for 20 years from the filing date of the patent application. Patents are granted with a presumption of validity but no patent is safe from being challenged and declared (partially) invalid by national courts or, in the case of European patents, revoked by the European Patent Office. Often, a claim of invalidity of a patent is a reaction to an action of the patentee, in particular an infringement action.
