Understanding the Machine or Transformation Test in Patent Law

The Machine or Transformation Test is a key standard used to determine whether a claimed process qualifies as patent-eligible subject matter.

What Is the Machine or Transformation Test?

The test asks whether the process is:

• Tied to a Specific Machine or Apparatus
• Transforms an Article or Object

Why Is the Test Important?

It plays a critical role in assessing patent eligibility under 35 U.S.C. Section 101, particularly for software, business methods, and abstract ideas.
