Information Not Limited to Patents and Publications in Supplemental Exam
Note:
Patent owners can submit any relevant information, not just patents, publications, or written statements, during a supplemental examination.

Unlike ex parte reexamination practice, the information that the patent owner may request to be considered, reconsidered, or corrected in a supplemental examination proceeding is not limited to patents, printed publications, and patent owner written statements under 35 U.S.C. 301. The “information” may include any information that the patent owner believes to be relevant to the patent. For example, the information may include not only a patent or a journal article, but also a sales invoice, or a transcript of an audio or video recording. In addition, the information submitted as part of a request for supplemental examination may involve any ground of patentability, such as, for example, patent eligible subject matter, anticipation, public use or sale, obviousness, written description, enablement, and indefiniteness.

Patent Owner Can Request Office to Reconsider Information
Note:
A patent owner may file a request for supplemental examination to have the Office consider, reconsider, or correct information believed relevant to the patent.

Where a patent owner desires that the Office consider, reconsider, or correct information, including prior art and incorrect or inconsistent positions, believed to be relevant to the patent, the patent owner may file a request for supplemental examination. See 37 CFR 1.601 – 1.625 and MPEP Chapter 2800. Supplemental examination became available on September 16, 2012, as a result of section 257 of Title 35, United States Code, which was added by Public Law 112-29, enacted on September 16, 2011, known as the Leahy-Smith America Invents Act (AIA). In particular, 35 U.S.C. 257(c)(1) states that “[a] patent shall not be held unenforceable on the basis of conduct relating to information that had not been considered, was inadequately considered, or was incorrect in a prior examination of the patent if the information was considered, reconsidered, or corrected during a supplemental examination of the patent.” Therefore, a patent owner may insulate the patent from being held unenforceable based on information submitted in a properly filed supplemental examination request.
