The disclosure in a patent specification must enable others to make an
d use the claimed invention. In the competitive biotechnology industry
, companies often seek broad claims to protect contemplated embodiment
s of their inventions that have not yet been reduced to practice. In I
n re Wright, the Federal Circuit recently challenged this approach whe
n it upheld the rejection, for lack of enablement, of all but the narr
owest claims to a vaccine genetically engineered to protect against re
troviruses. This decision unreasonably elevates the established standa
rd for enablement by limiting biotechnological patent protection to on
ly those embodiments of a claimed invention whose success can be demon
strated by working examples. This Note critiques that decision and pro
poses a limited policy-based approach to guide consistent determinatio
ns of enablement for patent claims.
