MPEP 2100 – Patentability (2)
The effect of the preamble on claim interpretation is determined on a case-by-case basis. As stated in MPEP 2111.02, “The determination of whether a preamble limits a claim is made on a case-by-case basis in light of the facts in each case; there is no litmus test defining when a preamble limits the scope of a claim.”
Generally, the preamble limits the claim if:
- It recites essential structure or steps
- It’s necessary to give life, meaning, and vitality to the claim
- It’s used to define the scope of the claimed invention
As the Federal Circuit stated in Bell Communications Research, Inc. v. Vitalink Communications Corp., “[A] claim preamble has the import that the claim as a whole suggests for it.”

How does the preamble affect claim interpretation in patent applications?
The preamble can significantly affect claim interpretation in patent applications. According to MPEP 2111.02, the effect of the preamble on claim scope can be summarized as follows:
- If the body of the claim fully and intrinsically sets forth the complete invention, and the preamble merely states the purpose or intended use, the preamble is generally not considered a limitation.
- However, if the preamble is “necessary to give life, meaning, and vitality” to the claim, it must be construed as a limitation.
- The determination of whether a preamble limits a claim is made on a case-by-case basis in light of the facts in each case.
The MPEP states: “Any terminology in the preamble that limits the structure of the claimed invention must be treated as a claim limitation.” This means that if the preamble introduces essential structure or steps, or if it’s necessary to understand the claim as a whole, it will be considered limiting.
