How does the USPTO determine if a claim falls within a statutory category?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The USPTO determines if a claim falls within a statutory category through Step 1 of the eligibility analysis. As described in MPEP § 2106, Step 1 asks: Is the claim to a process, machine, manufacture or composition of matter?

The MPEP provides guidance on this process:

  1. The claim should be evaluated using its broadest reasonable interpretation (BRI).
  2. The examiner should determine whether the claim as a whole falls within one or more statutory categories.
  3. If the claim falls within one or more categories (Step 1: YES), it proceeds to further analysis for eligibility.
  4. If the claim does not fall within any statutory category (Step 1: NO), it is non-statutory and should be rejected under 35 U.S.C. 101.

Importantly, “A claim whose BRI covers both statutory and non-statutory embodiments embraces subject matter that is not eligible for patent protection and therefore is directed to non-statutory subject matter. Such claims fail the first step (Step 1: NO) and should be rejected under 35 U.S.C. 101, for at least this reason.
