eMod - Patent Center

eMod: eCommerce Modernization 

eMod is an exciting project to improve the electronic patent application process by modernizing its filing and viewing systems. 

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
