Benefits of using the Electronic Filing System (EFS-Web)
- EFS-Web is safe. Filings made with EFS-Web provide you with the same legal protection as paper-based filings. You receive an electronic receipt and confirmation, as well as the ability to print the receipt for your records, affirming your receipt date.
- EFS-Web is simple. Even the largest and most complex patent applications can be submitted by attaching PDF files and filling out a few simple web screens.
- EFS-Web is secure. EFS-Web submissions are protected through state-of-the-art security methods, including Transport Layer Security (TLS), and if you sign up as a registered filer, Digital Certificates, one of the most secure methods now available.
- EFS-Web is fast. In just a few minutes and using a few web screens, you can submit a patent application, pay for your filing and receive an acknowledgment receipt.
- EFS-Web is flexible. EFS-Web requires you to make no changes to the tools, processes or workflows you use to author patent applications and documents. Filing with EFS-Web does not require you to learn how to use new authoring tools.
EFS-Web is forgiving. EFS-Web validates whether the PDF files and data you're trying to file can be accepted before they are submitted. If there's a problem, EFS-Web will tell you why the document can't be submitted - allowing you to take corrective action quickly.
