Why you should consider becoming a REGISTERED eFILER

  • What is a REGISTERED eFILER?

A Registered eFILER has both an assigned Customer Number and Digital Certificate for secure access to application documents both during and after the filing of a patent application.

  • Digital Certificates provide an e-Filer with the abillity to authenticate sessions by requiring positive identification of a customer using Public Key Infrastructure technologies.
  • Holders of Digital Certificates can take advantage of streamlined logins.
  • Registered e-Filers who authenticate can save "in-progress" submissions and return to edit them prior to completing filing.
  • This ability to save "in-progress" submissions provides added protection against loss of data in the event of a localized internet or office equipment failure or in the event of an unplanned system outage during an online filing session.
  • Registered e-Filers can electronically process subsequent actions on electronically filed cases without delay.
  • Registered e-Filers can review their confidential Private PAIR records for most of their electronically filed cases.
