This page summarizes the essential requirements for patent drawings, based on the Manual of Patent Examining Procedure (MPEP) and the United States Code (35 U.S.C.).

🔍 When Are Drawings Required?

  • Drawings are required in utility and design patent applications when necessary to understand the invention.

  • Legal Basis:

    • 35 U.S.C. § 113 – Drawings must be included where necessary for understanding.

    • MPEP § 608.02 – Explains when drawings are required and acceptable substitutes.
