Law - Revival of Unintentionally-Abandoned Application
An applicant's failure to prosecute a patent application will result in its abandonment. If the failure to prosecute is unintentional, the applicant can file a petition for revival of the application as a pending application. The petition must be filed either within 1 year of the date on which the application became abandoned or within 3 months of the date of the first decision on a petition to revive an unavoidably-abandoned application. (The petition to revive an unavoidably-abandoned application must have been filed within 1 year of the date on which the application became abandoned.)
