EFS-Web is the United States Patent and Trademark Office’s (USPTO’s) web-based patent application and document submission solution. Using EFS-Web, anyone with a web-enabled computer can file patent applications and documents without downloading special software or changing document preparation tools and processes.

EFS-Web utilizes standard web-based screens and prompts to enable you to submit patent application documents in PDF format directly to the USPTO within minutes. When creating your PDF documents, you choose the tool, process and workflow with which you author your documents; convert them to standard PDF files and then submit them to USPTO's secure servers. Additionally, EFS-Web 1.1 has expanded it's functionality to allow the submission of PCT EASY .ZIP compressed files to submit International PCT applications and ASCII text files (.TXT) to submit your bio-sequence listings, computer program listings, mega tables, etc. EFS-Web is safe, simple and secure and gives you all of the same benefits as paper filings, including an electronic receipt that acknowledges your submission date.

Full technical support is available through the Patent Electronic Business Center (EBC) at 866-217-9197 from 6 a.m. to 12 Midnight Eastern Time, Monday – Friday. Limited assistance is available at all other times through USPTO's Electronic Business Support (EBS) at 1 800 786-9199 or 571-272-1000.
