What is the relationship between the detailed description and the claims in a patent application?

The detailed description and the claims in a patent application have a crucial interdependent relationship. According to MPEP 608.01(g):

“The description is a dictionary for the claims and should provide clear support or antecedent basis for all terms used in the claims.”

This relationship is characterized by several key aspects:

• Support for Claims: The detailed description must provide sufficient information to support all the elements mentioned in the claims.
• Antecedent Basis: Terms used in the claims should be introduced and explained in the description, establishing an antecedent basis.
• Illustration Requirement: As stated in MPEP 608.01(g), “Every feature specified in the claims must be illustrated.”
• Clarity and Enablement: The description should enable a person skilled in the art to understand and implement the claimed invention without undue experimentation.
• Consistency: The terminology used in the claims should be consistent with that used in the description.

For more information on the relationship between claims and the specification, refer to MPEP § 608.01(o) and § 2111.01. Maintaining a clear and supportive relationship between the description and claims is essential for a strong and enforceable patent.
