MPEP 2100 – Patentability (5)
Antecedent basis is crucial for maintaining clarity in patent claims. The MPEP 2173.03 emphasizes its importance:
“Claim terms must find clear support or antecedent basis in the specification so that the meaning of the terms may be ascertainable by reference to the specification.”
Antecedent basis serves several important functions:
- Ensures clarity and definiteness of claim terms
- Provides a link between the claims and the specification
- Helps avoid indefiniteness rejections under 35 U.S.C. 112(b)
- Facilitates proper interpretation of claim scope
To maintain proper antecedent basis:
- Introduce elements in the claims with “a” or “an”
- Refer back to previously introduced elements with “the” or “said”
- Ensure that all claim terms have support in the specification
By maintaining proper antecedent basis, you can improve the overall quality and clarity of your patent application.

Yes, a claim preamble can provide antecedent basis for claim limitations, but this depends on the specific circumstances and the nature of the invention. The MPEP 2173.05(e) states:
“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.”
While this statement is not specifically about antecedent basis, it underscores the importance of the preamble in claim interpretation. In practice:
- If the preamble is considered to give life, meaning, and vitality to the claim, it can provide antecedent basis for later claim elements.
- Elements introduced in the preamble can be referred to later in the claim body using “the” or “said” if they are essential to the invention.
- However, if the preamble merely states the intended use or field of use, it may not provide proper antecedent basis for claim limitations.
For example, in a claim starting with “A method of treating diabetes comprising…”, the term “diabetes” could potentially provide antecedent basis for later references to “the disease” or “said condition” in the claim body, if diabetes is central to the invention.
It’s important to note that while preambles can provide antecedent basis, it’s often clearer and safer to introduce key elements in the body of the claim to avoid any ambiguity.

If the specification doesn’t provide adequate support or antecedent basis for claim terms, an examiner can take several actions. According to MPEP 2173.03:
“If the specification does not provide the needed support or antecedent basis for the claim terms, the specification should be objected to under 37 CFR 1.75(d)(1).”
The examiner’s actions may include:
- Objecting to the specification under 37 CFR 1.75(d)(1)
- Requiring the applicant to make appropriate amendments to the description
- Asking the applicant to amend the claims
The MPEP further states:
“Applicant will be required to make appropriate amendment to the description to provide clear support or antecedent basis for the claim terms provided no new matter is introduced, or amend the claim.”
It’s important to note that any amendments to the specification must not introduce new matter, as this would violate 35 U.S.C. 132(a).

“Lack of antecedent basis” refers to a situation in patent claims where a term is used without proper introduction or reference to a previously mentioned element. As stated in MPEP 2173.05(e):
“The lack of clarity could arise where a claim refers to ‘said lever’ or ‘the lever,’ where the claim contains no earlier recitation or limitation of a lever and where it would be unclear as to what element the limitation was making reference.”
This issue can lead to indefiniteness in claims, potentially rendering them unclear and therefore invalid under 35 U.S.C. 112(b).
To learn more:
What is the significance of the ‘the’ vs. ‘a’ or ‘an’ in patent claim language?
The use of ‘the’ versus ‘a’ or ‘an’ in patent claim language is significant for establishing proper antecedent basis. According to MPEP 2173.05(e):
“Obviously, however, the failure to provide explicit antecedent basis for terms does not always render a claim indefinite. If the scope of a claim would be reasonably ascertainable by those skilled in the art, then the claim is not indefinite.”
Generally, ‘a’ or ‘an’ is used when introducing an element for the first time, while ‘the’ is used for subsequent references to that element. However, the MPEP acknowledges that the absence of explicit antecedent basis doesn’t always make a claim indefinite. The key is whether the scope of the claim remains reasonably clear to those skilled in the art.
