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.

Examiners conduct prior art searches for plant patent applications using various resources. The MPEP § 1608 outlines the process: The prior art considered by the examiner is developed by a search of appropriate subclasses of the United States patent classification system as well as patent and nonpatent literature data bases.

This comprehensive approach ensures that examiners consider a wide range of relevant prior art, including:

  • Existing patents in related plant classifications
  • Scientific literature on plant varieties
  • Databases containing information on known plant species and cultivars

Additionally, examiners may consult with other government agencies for specialized knowledge: Where appropriate, a report may be obtained from the Agricultural Research Service, Horticultural Research Branch, Department of Agriculture.
