What makes a patent claim invalid under the enablement requirement?
A patent claim can be deemed invalid if it fails to meet the enablement requirement. The MPEP states:
“A patent claim is invalid if it is not supported by an enabling disclosure.“
This means that if the specification does not provide sufficient information for a person skilled in the art to make and use the invention as claimed, without undue experimentation, the claim may be invalid. The enablement requirement ensures that the public receives meaningful disclosure of the invention in exchange for the granted patent rights.
It’s important to note that enablement is assessed based on the knowledge available at the time of filing and considers the entire disclosure, including the specification, drawings, and any incorporated references. Courts will consider various factors, known as the Wands factors, to determine if undue experimentation would be required to practice the invention.
