LICENSING OF FUTURE INVENTIONS

Introduction and problem addressed[i]
Creative people and creative organizations are, well,
creative. A creative person does not turn off his or her brain
just because he or she has created an invention and licensed the
rights to that invention to someone else. The creative person
likely will create new inventions, including new inventions that are
improvements to the licensed invention. Those new inventions
may compete in the marketplace with the licensed invention.
A tension exists in the interests of the parties to a
license agreement relating to future inventions by the inventor.
In a license transaction, it generally is in the interest of the
inventor to retain and not to license the rights to future
inventions to maintain maximum flexibility on the part of the
inventor and to allow the inventor to realize the benefit of his or
her creativity.
In a license transaction, the licensee has a real interest
in developing and marketing the licensed invention without
interference from the inventor. If the inventor patents an
improvement to the licensed invention, the new patent will block the
licensee from practicing that improvement without an additional
license and additional royalties. If the inventor invents and
patents a new invention that will compete with the original
invention in the marketplace, the value of the license is diminished
because the value of the original invention is diminished.
Licensing unrelated future inventions
The courts frown on indefinite licenses of future
inventions; that is, of inventions that are unrelated to the
original licensed invention. As a result, the license
should not include a license of future inventions unrelated to the
original invention.
Common practice
A common practice is to include the term “and
improvements” to define the scope of the licensed subject matter.
The purpose of the “and improvements” language is to bring future
inventions by the inventor on the subject matter of the licensed
invention within the scope of the license.
The ‘and improvements’ language may introduce ambiguity
into the licensing agreement and may not accomplish the result
desired by the licensee or the licensor. The courts generally
find that the “improvement” licensed along with the underlying
issued patent is limited to any improvement the practicing of which
would infringe a claim of the patent. In other words,
inclusion of the phrase “and improvements” prevents the licensor
from enforcing a blocking patent against the licensee preventing
development of the patented invention.
Matters to be negotiated between the parties
Three categories of subject matter to be licensed should
be discussed in every license: the “licensed patent,” the
“improvement patent” and the “field of the invention patent.”
The “licensed patent” is the underlying issued patent that is the
subject of the license. The “improvement patent” is a future
patent the practicing of which would violate the claims of the
licensed patent. The “field of the invention patent” is a
future patent that would compete in the marketplace with the
licensed patent but would not infringe the claims of the licensed
patent. Licensors and licensees should specifically negotiate
and agree to licensing terms for any “improvement patent” and any
“field of invention patent.” Separate recitation in the
agreement of the terms on each, even if that agreement is to exclude
one or both categories of future patent rights from the license.
Consideration should be stated for each such future invention right.
