How detailed should the Brief Summary of Invention be in a patent application?
The Brief Summary of Invention should be concise yet informative. MPEP 608.01(d) provides guidance on the level of detail required: “That is, the subject matter of the invention should be described in one or more clear, concise sentences or paragraphs.” The summary should provide enough information to understand the nature and substance of the invention without delving into excessive technical details. It should focus on the key aspects that distinguish the invention from prior art and align with the claims. The MPEP also notes that “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 suggests that while being concise, the summary should be comprehensive enough to facilitate future patent searches and understanding of the invention.
