!19950929 TRW: should the PTO allow orbits to be patented?
One of my readers is an expert in outer/aerospace patent law, which
because of the communications industry and satellites, is not a trivial
legal area. He has graciously written an article for the patent news
service, which follows below. Please direct any questions by email to him.
====================
TRW SATELLITE CONSTELLATION CLAIM
Some Space Law Considerations
Sa'id Mosteshar
Few people involved in patent issues can be unaware of the
unusual history of the TRW patent Claim. TRW asserts that
its patent has in effect reserved to it the exclusive right
to use the medium earth orbit, MEO, for mobile satellite
communication systems. This would inhibit and prevent the
development of competing MEO systems.
The question that arises is whether the United Stares Patent
Office, PTO, can exercise its jurisdiction in a way that
grants a monopoly over certain uses of the relevant part of
outer space.
The TRW patent Claim relates to the provision of satellite-
based communications between low-powered handsets with omni-
directional antennae, using as a gateway a satellite forming
part of a constellation. TRW claims that its patent is not
limited to any individual element or step involved in the
formation or the operation of the constellation of
satellites. The Claim involves:
1 Launch of a constellation of satellites to between
5,600 and 10,000 nautical miles above the earth;
2 At least one satellite to have a reduced antenna field
of view, FOV, less than full earth coverage;
3 The satellites to be oriented in a plurality of
predetermined orbital planes;
4 Receiving radio frequency signals by at least one
satellite from a plurality of mobile handsets with omni-
directional antennae;
5 Overlapping of a portion of the coverage region of a
departing satellite with a portion of the coverage
region of an arriving satellite;
6 Predetermined criteria for the assignment of calls to
or from users within the coverage overlap region from a
departing satellite to an arriving satellite (call hand-
over).
Clearly, TRW could secure a patent in respect of
implementation of some individual steps, if they are novel
and unobvious. There is much prior art in relation to many
of these elements.
But TRW asserts that the use of the MEO for mobile satellite
communications requires that the system have all the
characteristics outlined in the Claim. An essential element
of the TRW patent is the location of the satellite
constellation at MEO of between 5,600 and 10,000 nautical
miles. The attraction of the MEO is the reduced number of
(admittedly more powerful) satellites necessary for global
communications. The patent granted to TRW is in reality a
narrow one for a particular use of the MEO. However, TRW
asserts that it has achieved its broader objective.
United States Patent Law Extension to Objects in Outer Space
The United States amended its patent legislation in 1990 to
extend its jurisdiction to objects in outer space. Acts on
a "space object or component thereof under the jurisdiction
or control of the United States" are treated as taking place
within the United States.
Under this part of the legislation it is necessary to show
an act on a specific space object, such as a satellite or
the Space Shuttle which is carried on the registry of the
United States. An example of such an act would be carrying
out a patented manufacturing process within the Shuttle.
However, the legislation does not purport to and does not
have the effect of extending the patent jurisdiction of the
United States to any part of outer space per se, merely to
the space object itself.
United States Patent Infringement Provisions
Even prior to 1990, United States patent legislation
provided that in some circumstances, a person arranging for
implementation outside the territory or jurisdiction of the
United States, of certain actions specified in a US patent,
that person is infringing the US patent.
Even though the relevant actions take place outside the
United States, infringement is deemed to occur inside the
United States. It is therefore arguable that if the
satellites for an MEO system are made in the United States,
but the launch takes place elsewhere, the provider of the
satellites has infringed the TRW patent in the United
States. An attempt by someone other than TRW to circumvent
the patent by launching a US-made cluster of satellites from
another country would fail under these provisions.
Implications of the TRW Claim
Communications is still the most significant activity in
outer space. Mobile satellite communications is growing in
significance more rapidly than any other single use of outer
space. Even at this early stage of the game there are three
systems designed for operation in MEO and 13 systems
intending to use LEO. There are certain technical and
economic features that make MEO systems more desirable [See
"Big and Small", Aerospace America, September 1995].
If the grant has the effect claimed by TRW, the PTO has
made the MEO substantially unavailable for use by any other
entity. To the extent that most of the capital and the
satellites for such systems will originate in the United
States, the TRW patent would preclude MEO use by the
majority of other countries that might desire to establish
MEO systems
International Law of Outer Space
The United States is Party to the Outer Space Treaty 1967 ,
OST. Two fundamental principles of Outer Space Law are:
"Outer space, including the moon and other celestial
bodies, shall be free for ... use by all States without
discrimination of any kind ... ", and
that "Outer space, including the moon and other
celestial bodies, is not subject to national
appropriation by claims of sovereignty, by means of use
or occupation, or by any other means".
If the TRW assertion is correct, by its grant the PTO has
appropriated to the United States' patent sovereignty a part
of outer space, in breach of the United States' obligations
under the OST. Such an exercise of sovereignty by the PTO
is clearly beyond what the United States recognizes as the
limits of its patent jurisdiction, as permitted under the
OST, and evidenced in the 1990 amendment.
Furthermore, the TRW patent would de facto preclude other
States from free use of a part of outer space, contrary to
the OST. This also contravenes the principle that "the ...
use of outer space ... shall be the province of all
mankind".
Conclusion
This is a much abbreviated argument based on the
international law obligations of the United States and its
impact on patents relating to the use of parts of the outer
space. Nevertheless, it should be apparent that there are
serious issues that need to be addressed. If the PTO grant
has the effect asserted by TRW, then the PTO has exceeded
its jurisdiction in granting the Claim of TRW as it relates
to the MEO.
