Patent Law FAQ

The interpretation of “wherein” and “whereby” clauses in patent claims depends on their specific context and effect on the claim. According to MPEP 2111.04:

“The determination of whether each of these clauses is a limitation in a claim depends on the specific facts of the case.”

For “wherein” clauses, they can be limiting if they give “meaning and purpose to the manipulative steps” as noted in Griffin v. Bertina.

For “whereby” clauses, the Hoffer v. Microsoft Corp. case provides guidance:

• If a “whereby” clause states a condition that is material to patentability, it cannot be ignored.
• However, in a method claim, a “whereby” clause that simply expresses the intended result of a process step positively recited is not given weight.

Patent attorneys and examiners should carefully analyze these clauses to determine if they add limitations to the claim or merely state the intended result of other claim elements.

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.
