Patent notification Require patent information in drug registration applications Require publication of drug patent status information Certification process Require a generic applicant to certify in its drug registration its position on the listed patents relevant to its generic application Notice to the originator Reqire a generic applicant to notify the innovator of its application for drug registration and explain the reasons for claiming that the underlying patent will not be infringed or is invalid Allow for a reasonable period of time for the originator to file an infringement suit and inform the regulatory agency – the reasonable period of time depends on local legal procedures and review times Automatic stay of approval Require suspension of market approval of a generic drug until resolution of the patent dispute Back to Contents
