Welcome to Electronic Patent Filing for UNREGISTERED eFILERS
A submission has not been filed officially at the USPTO until the e-filer executes the Submit function and the documents are received at the USPTO Eastern Time. The Acknowledgement Receipt is evidence of this submission.
All items denoted by * are required.
ADVISORY 4AUG20: Due to a technical problem, the acknowledgement receipts for EFS-Web submissions filed between Aug 2, 9:40 p.m. and Aug 3, 10:25 a.m. (ET) are not yet available in Private PAIR. If you calculated and paid fees, your fee payment was successfully recorded in our payment system; however, the system generated fee transmittal was incorrect and needs to be corrected. Other generated PDFs have also been delayed, such as Web ADS, ePetition, eTerminal Disclaimer, and Web 85b. USPTO is working diligently to address this issue and estimates that the delayed system generated PDF documents will be available in Private PAIR in 7-10 days.
If you close or exit the eFiling portal you will lose your work.
For your convenience, all links in the left hand side of the eFiling portal will open in new windows to help prevent accidental loss of information during filing.
Context-sensitive help (information graphic links) will appear in a new window.
Why you should consider becoming a REGISTERED eFILER
What is a REGISTERED eFILER?
A Registered eFILER has both an assigned Customer Number and Digital Certificate for secure access to application documents both during and after the filing of a patent application.
Digital Certificates provide an e-Filer with the abillity to authenticate sessions by requiring positive identification of a customer using Public Key Infrastructure technologies.
Holders of Digital Certificates can take advantage of streamlined logins.
Registered e-Filers who authenticatecan save "in-progress" submissions and return to edit them prior to completing filing.
This ability to save "in-progress" submissions provides added protection against loss of data in the event of a localized internet or office equipment failure or in the event of an unplanned system outage during an online filing session.
Registered e-Filers can electronically process subsequent actions on electronically filed cases without delay.
Registered e-Filers can review their confidential Private PAIR records for most of their electronically filed cases.
