This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

While MPEP 715.01(d) doesn’t explicitly define a statutory bar, it mentions it as an exception to when certain rejections can be overcome. The section states:

“Unless it is a statutory bar, a rejection under pre-AIA 35 U.S.C. 102 or 103 based on an activity showing that the claimed invention was used or known prior to the filing date of the application may be overcome…”

A statutory bar refers to certain events or activities that, if they occur more than one year before the filing date of a patent application, will permanently bar the inventor from obtaining a patent. These are defined in pre-AIA 35 U.S.C. 102(b) and typically include:

  • Public use of the invention in the U.S.
  • Sale or offer for sale of the invention in the U.S.
  • Printed publication describing the invention anywhere in the world

If a statutory bar exists, the applicant cannot overcome the rejection using the methods described in MPEP 715.01(d), such as swearing behind the reference with an affidavit or declaration.
