What is the difference between a specification and claims in a patent application?

The specification and claims are distinct but related parts of a patent application:

• Specification: This is a detailed written description of the invention. According to MPEP 601.01, it must contain “a description pursuant to 35 U.S.C. 112(a).” The specification explains how to make and use the invention and provides the context for understanding the claims.
• Claims: These define the legal scope of patent protection. The MPEP states that an application must include “at least one claim pursuant to 35 U.S.C. 112(b).” Claims outline the specific elements of the invention that the applicant considers novel and seeks to protect.

The MPEP further clarifies: “The specification must include a written description of the invention or discovery and of the manner and process of making and using the same, and is required to be in such full, clear, concise, and exact terms as to enable any person skilled in the art or science to which the invention or discovery appertains, or with which it is most nearly connected, to make and use the same.”

While the specification provides a comprehensive description, the claims define the boundaries of the patent rights. Both are crucial for a complete and effective patent application.
