Patent Center has 100% of the functionality of EFS-Web, Public and Private PAIR, and is available to all users for electronic filing and management of patent applications.
Patents with an issue date on or after April 18, 2023 are issued as electronic patent grants (eGrants).
Filing a new non provisional 111(a) application? Starting January 17, 2024, specification, claims and abstracts not filed in DOCX format will incur a non-DOCX surcharge of up to $400 for this filing type. See the Federal Register notice for more information.
Extended until further notice, exclusively in Patent Center, applicants have the option to upload a backup (auxiliary) PDF version of their application with their DOCX version. There are no fees associated with this auxiliary PDF. See the Federal Register notice for more information.
Attend a DOCX training webinar or visit the DOCX information page to learn more about filing in DOCX format.
