How can I submit prior art or written statements under 37 CFR 1.501?

Prior art patents, printed publications, and/or written statements under 37 CFR 1.501 can be submitted to the USPTO via:

  • Mail
  • Hand-delivery
  • The Office’s Electronic Filing System (EFS, currently EFS-Web)

The MPEP states, “Both registered and unregistered eFilers may make a submission for a patent under 37 CFR 1.501 via EFS.” However, it’s important to note that “A submission under 37 CFR 1.501 cannot be filed via EFS for design or plant patents.
