How does the USPTO determine if a disclosure lacks enablement?

The USPTO determines if a disclosure lacks enablement by evaluating the evidence related to the Wands factors. According to MPEP 2164.01(a):

“A conclusion of lack of enablement means that, based on the evidence regarding each of the above factors, the specification, at the time the application was filed, would not have taught one skilled in the art how to make and/or use the full scope of the claimed invention without undue experimentation.”

This determination is not a simple factual assessment but a conclusion reached by weighing all the Wands factors. The examiner must consider all evidence related to these factors, and any conclusion of nonenablement must be based on the evidence as a whole.
