For patent and trademark applications, where the failure to submit a priority document within the statutory time limit is due to causes not attributable to the applicant, the applicant may request reinstatement in accordance with Article 17, Paragraph 2 of the Patent Act and Article 12 of the Enforcement Rules of the Patent Act, or Article 8, Paragraph 2 of the Trademark Act and Article 9 of the Enforcement Rules of the Trademark Act, accompanied by the document(s) of proof.

Relevant documents of proof may include official documents issued by USPTO or emails sent from official USPTO email accounts. These documents must clearly state the reason for the delay (e.g., insufficient manpower or other causes) and specify the priority application number (or order number). TIPO will determine whether to grant reinstatement on a case-by-case basis.
