pronounced of late. For one thing, while the utility requirement is generous, it
has its limits.
118
An invention must actually work to be considered useful, even
if it need not work especially well.
119
Moreover, the mere possibility, and
perhaps even likelihood, that some use for an invention will later be discovered
is insufficient to support a patent grant.
120
In addition, the invention must have
some demonstrated benefit, however slight. Significantly, the Supreme Court
has held that a substance cannot be considered useful merely because it is an
object of active research by scientists, who suspect it may have beneficial
properties.
121
This restriction, too, has been expanded upon and given more teeth
in recent cases.
122
So while patent law does award rights at an earlier stage in the
overall developmental process than it might, it also contains rules that limit early
awards. The utility requirement thus serves as a doctrinal tool that draws the line
between information that is and is not subject to individual ownership.
Other features of patent law also limit the availability of patents at very early
stages of the inventive process. Under a set of long-standing judge-made
exceptions to the statutory provision governing patentable subject-matter,
abstract ideas and laws of nature, though often very valuable, are categorically
excluded from patent protection.

only utility requirement is particularly useful in determining how far removed research is from
commercial end product to explain that strict interpretation of usefulness can be limiting).

See Newman v. Quigg, 877 F.2d 1575, 1581-82 (Fed. Cir. 1989) (rejecting patent for
perpetual motion device because it was inoperable and therefore lacked utility).

not be granted on speculation of future usefulness).

specific benefit exists in currently available form—there is insufficient justification for
permitting an applicant to engross what may prove to be a broad field.”).
