What information is considered material to patentability?

Information material to patentability is broadly defined in 37 CFR 1.56. It includes:

  • Prior art such as patents and publications
  • Information on enablement
  • Possible prior public uses, sales, or offers to sell
  • Derived knowledge
  • Prior invention by another
  • Inventorship conflicts
  • Litigation statements

As stated in the MPEP, “Materiality is not limited to prior art but embraces any information that a reasonable examiner would be substantially likely to consider important in deciding whether to allow an application to issue as a patent.” This broad definition ensures that examiners have access to all relevant information when making patentability determinations.
