How are mathematical concepts evaluated as abstract ideas?

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:

  1. Does the claim recite a mathematical relationship, formula, equation, or calculation?
  2. 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.
