Supplemental examinations  provide a patent owner a procedure to request the Patent Office to consider, reconsider, or correct information believed to be relevant to the patent at issue.  Supplemental examinations are part of the America Invents Act, which became effective on September 16, 2012.

The information a patent owner may request to be considered is not as limited as the art that can be brought before an examiner as part of an ex parte reexamination. The information may include any information that the patent owner believes to be relevant to the patent.  Further, the grounds for supplemental examination include any ground of patentability, including patent eligible subject matter, anticipation, public use or sale, obviousness, written description, enablement, indefiniteness, and double-patenting.
