What are examples of predictable and unpredictable arts in patent law?

In patent law, the predictability of an art affects the level of disclosure required for enablement. MPEP 2164.03 provides examples:

Predictable arts typically include:

  • Mechanical devices
  • Electrical devices

Unpredictable arts often include:

  • Chemical arts
  • Biotechnology

The MPEP states: “In cases involving unpredictable factors, such as most chemical reactions and physiological activity, more may be required.”

This distinction is important because inventions in unpredictable arts generally require more detailed disclosure to satisfy the enablement requirement, while those in predictable arts may require less detailed guidance.
