What level of detail is required in the ‘Detailed Description of Invention’ section?

The ‘Detailed Description of Invention’ section requires a comprehensive and precise level of detail. According to MPEP 608.01(g):

“This detailed description, required by 37 CFR 1.71, MPEP §§ 608.01, 2161, and 2162, must be in such particularity as to enable any person skilled in the pertinent art or science to make and use the invention without involving extensive experimentation and must clearly convey enough information about the invention to show that applicant invented the subject matter that is claimed.”

The level of detail should include:

  • Enablement: Sufficient information for a skilled person to make and use the invention without undue experimentation.
  • Complete Disclosure: All aspects of the invention claimed should be thoroughly described.
  • Clear Support: Provide clear support for all terms used in the claims.
  • Best Mode: The best mode contemplated by the inventor for carrying out the invention.
  • Drawings Reference: Detailed explanation of all parts referenced in the drawings.

While the description should be comprehensive, it’s important to note that grammatical perfection is not the primary focus. The key is to provide a clear, enabling disclosure of your invention that supports your claims and demonstrates your invention to the fullest extent.
