Establishing Permanent Electronic Filing for Patent Term Extension Applications

To further advance the United States Patent and Trademark Office's (USPTO or Office) information technology strategy of achieving complete beginning-to-end electronic processing of patent-related submissions, the USPTO is revising the Rules of Practice in Patent Cases to require that patent term extension (PTE) applications, interim PTE applications, and any related submissions to the USPTO be submitted electronically via the USPTO patent electronic filing system (Patent Center or EFS-Web). The rule changes reduce the administrative burden on PTE applicants and improve administrative efficiency by facilitating electronic file management, optimizing workflow processes, and reducing processing errors.
