MPEP 2100 – Patentability (5)
Mathematical concepts are one of the three main categories of abstract ideas identified in the MPEP. The MPEP states:
“The mathematical concepts grouping is defined as mathematical relationships, mathematical formulas or equations, and mathematical calculations.“
When evaluating whether a claim recites a mathematical concept, examiners consider the following:
- Does the claim recite a mathematical relationship, formula, equation, or calculation?
- Is the mathematical concept merely based on or involves a mathematical concept?
The MPEP clarifies: “A claim does not recite a mathematical concept (i.e., the claim limitations do not fall within the mathematical concept grouping), if it is only based on or involves a mathematical concept.“
Examples of mathematical concepts considered abstract ideas include:
- A formula for computing an alarm limit (Parker v. Flook)
- A method of hedging risk (Bilski v. Kappos)
- An algorithm for converting binary-coded decimal numerals into pure binary form (Gottschalk v. Benson)
It’s important to note that a claim is not automatically ineligible just because it involves a mathematical concept. The claim as a whole must be evaluated to determine if it integrates the mathematical concept into a practical application or provides an inventive concept.

The Alice/Mayo test, also known as the Mayo test, is a two-part framework established by the Supreme Court for determining patent subject matter eligibility. According to the MPEP:
“The first part of the Mayo test is to determine whether the claims are directed to an abstract idea, a law of nature or a natural phenomenon (i.e., a judicial exception). … If the claims are directed to a judicial exception, the second part of the Mayo test is to determine whether the claim recites additional elements that amount to significantly more than the judicial exception.”
This test helps examiners and courts evaluate whether a claimed invention is directed to a judicial exception and, if so, whether it includes additional elements that transform it into patent-eligible subject matter.

The Alice/Mayo framework, as discussed in MPEP 2106, has significant implications for software and business method patents. This framework, established by the Supreme Court decisions in Alice Corp. v. CLS Bank International and Mayo Collaborative Services v. Prometheus Laboratories, Inc., has made it more challenging to obtain patents for certain types of software and business methods.
Key implications include:
- Increased scrutiny: Software and business method patents face heightened scrutiny under the Alice/Mayo framework, particularly regarding abstract ideas.
- Focus on technical improvements: Claims that demonstrate a technical improvement or solve a technical problem are more likely to be found eligible.
- Importance of practical application: Software and business method inventions that integrate abstract ideas into practical applications are more likely to be patent-eligible.
- Detailed claim drafting: Claims must be carefully drafted to emphasize technical elements and avoid being characterized as merely implementing abstract ideas on generic computer components.
The MPEP notes: “The courts have found software and business method claims ineligible for patent protection under 35 U.S.C. 101 in some instances, but not in others. It is important to remember that a mathematical concept, an abstract idea, or other judicial exception in a claim does not automatically render the claim as a whole ineligible for patenting.“
Applicants and practitioners must carefully consider the Alice/Mayo framework when drafting and prosecuting software and business method patent applications to improve their chances of obtaining patent protection.

The use of a computer in a claim does not automatically disqualify it from being considered a mental process. The MPEP provides guidance on how to evaluate such claims:
“Claims can recite a mental process even if they are claimed as being performed on a computer. The Supreme Court recognized this in Benson, determining that a mathematical algorithm for converting binary coded decimal to pure binary within a computer’s shift register was an abstract idea.”
When evaluating computer-implemented claims, examiners consider whether the claim:
- Recites a mental process performed on a generic computer
- Recites a mental process performed in a computer environment
- Uses a computer as a tool to perform a mental process
The MPEP provides examples for each scenario, such as:
- Collecting information, analyzing it, and displaying results (Electric Power Group v. Alstom)
- Claiming a process of translating a functional description of a logic circuit into a hardware component description (Synopsys v. Mentor Graphics)
The key is to determine whether the claim is directed to an improvement in computer functionality or merely uses the computer as a tool to perform a process that could be done mentally. The mere recitation of computer implementation is not enough to transform a mental process into a patent-eligible invention.

The USPTO uses a two-step process to determine if a claim recites an abstract idea:
- Evaluate the claim language: Examiners analyze the claim to identify any concepts that may be abstract ideas.
- Compare to established abstract idea categories: The identified concepts are compared to the enumerated groupings of abstract ideas and previous court decisions.
According to MPEP 2106.04(a): “To determine whether a claim recites an abstract idea in Prong One, examiners are now to: (a) Identify the specific limitation(s) in the claim under examination (individually or in combination) that the examiner believes recites an abstract idea; and (b) determine whether the identified limitation(s) falls within the subject matter groupings of abstract ideas enumerated in Section I of the 2019 Revised Patent Subject Matter Eligibility Guidance.”
