- Claims that cover a vast class that is defined by its function while only being enabled for a small number of species of that class via a method requiring elaborate experimentation do not meet the enablement requirement of §112 of the Patent Act.
- For enablement, a specification need not describe how to make and use every single embodiment within a claimed class, but should disclose some general quality running through the class that gives it a “peculiar fitness for the particular purpose.”
- A specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of theinvention and the underlying art.
