What is the difference in enablement requirements between predictable and unpredictable arts?
The enablement requirements differ significantly between predictable and unpredictable arts. According to MPEP 2164.03:
- Predictable arts (e.g., mechanical or electrical elements): A single embodiment may provide broad enablement. The MPEP states, “A single embodiment may provide broad enablement in cases involving predictable factors, such as mechanical or electrical elements.”
- Unpredictable arts (e.g., chemical reactions or physiological activity): More detailed disclosure is typically required. The MPEP notes, “In applications directed to inventions in arts where the results are unpredictable, the disclosure of a single species usually does not provide an adequate basis to support generic claims.”
This distinction is based on the ability of a person skilled in the art to extrapolate from the disclosed embodiments to other variations within the scope of the claims. In unpredictable arts, this extrapolation is more challenging, necessitating more comprehensive disclosure to satisfy the enablement requirement.
