Enablement, or sufficiency of disclosure, is the requirement that a patent allows a person skilled in the art to reproduce the claimed invention.

The legal requirement of enablement or sufficiency of disclosure*, states that a patent must describe the invention in sufficient detail so that a person skilled in the art would be able to reproduce the claimed invention without undue further experimentation.

In the United States, this requirement is established by 35 USC §112. There is an additional requirement that the inventor must present the “best mode” known to him, i.e. not withhold information that is relevant to carrying out the invention. In Europe, the requirement is disclosure according to article 83.
