INTRODUCTION
Field of use limitation refers to a provision in a patent license
that limits the scope of a patent owner to authorize a
manufacturing licensee who manufactures a patented product
or performs a patented process to do in relation to the patent,
by specifying a defined field of use.
Field of use limitation also specifies those fields of use from
which a licensee is excluded.
A licensee’s act amounts to patent infringement if the licensee
exceeds the scope of license granted.

FIELD-OF-USE LICENSING –
WHEN DO WE NEED IT??
• When more than one company is needed to fully develop a
technology’s potential.
• When different licensees are needed to address different markets.
• When field-of-use licensing has the potential to significantly
increase the financial return from a technology.
• In all of these situations, field-of-use licensing can produce
better results for everyone involved.

• A license might authorize a licensee to manufacture patented
engines only for incorporation into trucks, or to manufacture a
chemical only for sale to farmers (as contrasted with home
gardeners).
• If the licensee exceeded the scope of the license, he would
commit patent infringement.
• The license permits the licensee to use the patented invention in
some, but not all, possible ways in which the invention could be
exploited.

• General Talking Pictures Corp. v. Western Electric Co
• a license might authorize a licensee to manufacture patented
engines only for incorporation into trucks (the "truck field"), or
to manufacture such engines only for sale to farmers (the "field
of distribution to farmers").
• The doctrine of the General Talking Pictures case does not
apply to a patent owner’s sale (or its licensee's sale) of a
product to a customer that imposes a restriction on what the
customer may subsequently do with the product.

• A licensor might grant one licensee the right to practice the
patent solely to manufacture and sell a particular product and
grant a second licensee the right to practice the patent to
manufacture and sell a different product.
• However, a restriction on field of use imposed by a potential
licensor can reduce the motivation of a potential licensee, so a
balance must be struck between the needs and motivations of
each party to the license.

FIELD OF USE – STRENGTHENS THE PATENT
HOLDER AS AGAINST THE LICENSEE
• The licensee’s right to use the technology is limited in scope.
• Field of use limitation is powerful - electrical engineering,
computer, chemical, and health care areas.
• Biochemistry/Biotechnology industry runs by strategizing the
field of use in licensing.
• A company that develops therapeutics may not be interested in
performing DNA-based diagnostic tests as a service.

• License it to one company with no limitations.
• License it to one company with the requirement that it
develop all uses, either directly or through sublicensing.
• License it to multiple companies with field-of-use licenses.
• Most importantly, a patent holder must ascertain the possible
fields of use.

APPROACHES IN
LICENSING PATENTS
• Like any legal contract, the more rigid the licensing agreement is,
the better is the IP strategy.
• Make the “grant clause” as specific as possible.
•Define the Licensed Field of Use to prevent any possiblities of
Infringement.
• Limit the field of use of a license by limiting the grant of rights to

CONCLUSION
Field of Use is a grey area in a country like India. While we are
concentrating on securing patents, adequate importance should be
given to applying intelligent strategies for monetizing the same.
Field of Use Limitation is undoubtedly a boon for the strategizing
departments for individual and giant patent holders to push the
scope of their patents to higher levels.
