What should be included in the Brief Summary of Invention?

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.

According to MPEP 608.01(d) and 37 CFR 1.73, the Brief Summary of Invention should include:

• The nature and substance of the invention
• Optionally, a statement of the object of the invention
• One or more clear, concise sentences or paragraphs describing the subject matter of the invention
• The exact nature, operation, and purpose of the invention

The MPEP states, “The brief summary, if properly written to set out the exact nature, operation, and purpose of the invention, will be of material assistance in aiding ready understanding of the patent in future searches.” This emphasizes the importance of clarity and specificity in the summary.
