MPEP 2100 – Patentability (3)
Before conducting an enablement analysis, it is crucial for the examiner to construe the claims. The MPEP 2164.04 emphasizes this point:
“Before any analysis of enablement can occur, it is necessary for the examiner to construe the claims.“
For terms that are not well-known in the art or could have multiple meanings, the examiner must:
- Select the definition they intend to use when examining the application
- Base this definition on their understanding of what the applicant intends it to mean
- Explicitly set forth the meaning of the term and the scope of the claim when writing an Office action
This step is crucial because the enablement requirement is directly related to the scope of the claims, and a proper understanding of the claim terms is necessary to assess whether the disclosure enables the full scope of the claimed invention.

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.”

Transitional phrases play a crucial role in patent claim construction by defining the scope of the claimed invention. According to MPEP 2111.03, transitional phrases “define the scope of a claim with respect to what unrecited additional components or steps, if any, are excluded from the scope of the claim.”
The significance of transitional phrases includes:
- Determining claim scope: They indicate whether the claim is open-ended or closed, affecting what elements can be included in the claimed invention.
- Infringement analysis: The choice of transitional phrase impacts how potential infringement is evaluated.
- Patentability assessment: Examiners use transitional phrases to understand the boundaries of the claimed invention when comparing it to prior art.
For example, the phrase “comprising” in “A composition comprising X, Y, and Z” allows for additional, unrecited elements, while “consisting of” in “A mixture consisting of A and B” excludes any elements not specified.
Understanding and correctly using transitional phrases is essential for patent drafters, examiners, and litigators to accurately define and interpret the scope of patent claims.

MPEP 2164.04 – Burden On The Examiner Under The Enablement Requirement (1)
Before conducting an enablement analysis, it is crucial for the examiner to construe the claims. The MPEP 2164.04 emphasizes this point:
“Before any analysis of enablement can occur, it is necessary for the examiner to construe the claims.“
For terms that are not well-known in the art or could have multiple meanings, the examiner must:
- Select the definition they intend to use when examining the application
- Base this definition on their understanding of what the applicant intends it to mean
- Explicitly set forth the meaning of the term and the scope of the claim when writing an Office action
This step is crucial because the enablement requirement is directly related to the scope of the claims, and a proper understanding of the claim terms is necessary to assess whether the disclosure enables the full scope of the claimed invention.
