Proof of Commerce Filing Extension

File Your Extension Request

Formally petition the USPTO for a 6-month Filing Extension Protocol to file your Proof of Commerce Filing (SOU). Under 37 C.F.R. Sec.2.89, applicants may request subsequent extensions to preserve their priority filing date while finalizing commerce verification. Our automated system ensures your request meets all statutory requirements and is submitted within the critical filing window to prevent abandonment of your trademark application.
