EFS-Web Online Filing System: Features

Registered and Unregistered Filers

While anybody can submit patent applications and documents using EFS-Web, filers can gain more benefits from the system by registering, such as the option to file follow-up papers and save the package before submitting it. It’s simple to register by sending paper forms to the USPTO’s Patent Electronic Business Center (EBC), which will subsequently provide a Digital Certificate that verifies your identity.

Web Access

To file electronically, all you need is a computer, a Web browser, and an Internet connection. Click on the “File Online” link on the USPTO homepage at http://www.uspto.gov/ to access EFS-Web. After selecting Launch EFS-Web as a Registered or Unregistered e-Filer, you will be requested to submit your documents through a series of windows.

Filing Accepted

At the US Receiving Office, EFS-Web receives new:

  • Utility (reissues, requests for reexaminations);
  • Provisional;
  • Design;
  • National Stage Applications under 35 USC 371; and
  • PCT International Applications.

Further, registered e-filers can also submit Pre-Grant Publication papers and follow-up documents for previously filed applications.

Built-in File Validation

EFS-Web verifies documents automatically and tells you whether your application fits USPTO criteria before you submit it. If it fails to meet these requirements, you will be notified so that you can remedy the problem before final submission.

Online Payment of Fees

You can pay your filing fees online using EFS-Web. You have the choice of paying with a credit card, a deposit account, or an electronic funds transfer.

Acceptable File Formats

Standard PDF documents, text files (for specific application elements like sequence listings and computer program listings), and PCT-EASY ZIP files up to 25 gigabytes are all accepted by EFS-Web. Text files containing sequence listings can be up to 100 gigabytes in size. When properly set up, most versions of PDF writer software operate with EFS-Web.

Valid Electronic Receipts

EFS-Web generates an Acknowledgement Receipt with the following information:

  • Time and date stamp;
  • Application number; and
  • Confirmation number.

Further, the security and authority of the postcard receipt offered with paper applications are carried over to this electronic receipt.

Private PAIR Integration

The Private Patent Application Information Retrieval (PAIR) system may access EFS-Web submissions. Your patent applications and documentation are accessible to view in Private PAIR shortly after filing if you are a registered filer. With a single login, you can access both EFS-Web and Private PAIR.

Auto-process E-Petitions

Allows e-Filers to file e-Petitions that are automatically processed and approved if the petition criteria are met.


Whether a registered or unregistered filer, EFS-Web forms a secure hosted application. Your documents will undergo transmission via the Transport Layer Security (TLS) or Secure Socket Layer (SSL) protocol if you file as an unregistered filer. If you want to register, your filings remain handled through a Public Key Infrastructure system that ensures authentication and encryption.
