What is a statutory bar in the context of MPEP 715.01(d)?

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.
