About Patent Center

Patent Center

Patent Center is the new tool in development, which features a unified interface, with all of the capabilities from today's tools in a single place, and so much more. Patent Center will replace the Electronic Filing System - Web (EFS-Web), the current web-based patent application and document submission tool; and the Patent Application Information Retrieval (PAIR) system, the current web-based solution to retrieve and download information regarding patent application status. 


  • Updated infrastructure to enable more efficient system integration
  • Increased functionality and overall system usefulness
  • Enhanced user experience through improved interface
  • Improved processes for patent submission, review, and management
  • Revamped authentication process 
  • Increased accuracy of application processing and publication
