What is the role of the specification in patent claim analysis?
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.
The role of the specification in patent claim analysis is to provide context and support for the claims. According to MPEP 904.01:
The specification may be used to learn the meaning of terms and in interpreting the coverage of a claim, but limitations from the specification may not be read into the claims.
This means that while the specification helps understand the claims, examiners should not import limitations from the specification that are not explicitly stated in the claims themselves. The specification serves as a guide but does not override or modify the actual claim language.
