takes legal action against patent violators is often
faced with the burden of proof of ownership. The
failure to obtain a patent encourages active infringe-
ment, and increases the subsequent legal costs and
difficulty of proving a case.The legal costs incurred
in a single court can easily exceed the registration
costs in several countries.
In the process of filing for patent protection, it is
a good idea to make a distinction between common
law countries and statute law countries.A common
law country determines patent ownership by pri-
ority in use. In comparison, the ownership in a
statue law country is determined by priority in
registration; that is, the first-to-file is granted a
patent even if an innovation was actually created or
used earlier by someone else. Europe, Japan, China,
and most countries have the first-to-file patent
system, and they make patent applications public
eighteen months after filing.The USA, as a common
law country, relies on the first-to-invent system.
The US system’s first-to-invent standard is different
because it awards patents to the original inven-
tor even though someone else may have got to
the patent office first. Based on the US system, the
person who had the idea first receives a patent, and
patent applications are kept secret – sometimes for
years – until a patent is granted. It is true that
the European and Japanese systems, by publishing
patent information early, encourage imitators, but
at the same time, this practice alerts other inventors
early enough to avoid redundant research.
The USA was not consistent in treating American
and foreign inventors.Although the USA insisted on
giving ownership to the first-to-invent, that rule did
not protect overseas inventors. US patent law made
it clear that research efforts taking place outside the
USA could not be used to prove when an invention
was conceived. Thus an American inventor would
still get ownership if he or she started working on
a certain concept before a foreigner’s application for
a US patent – even though the foreigner actually
discovered that idea earlier overseas. After decades
of favoritism, the US Patent & Trademark Office, as
mandated by GATT, began giving equal treatment
to overseas inventors in 1996.
The Japanese patent practices appear to discrim-
inate against foreign applicants who have to wait
longer than their Japanese counterparts for a patent
to be granted. In contrast, the US, German, and
British practices may discriminate against foreign
applicants with lower patent grant ratios than for
domestic applicants. The USA and Japan seem to
have different philosophies concerning patents. In
the USA, patents are one’s property. In Japan,
patents are regarded as public good, and that is why
such practices as compulsory licensing and early
publication are encouraged.

The USA has complained about other countries’
systems, while those countries have urged the USA
to become more efficient and consistent with the
rest of the world by adopting the system of award-
ing a patent to the first inventor who applies on an
invention. The rationale of the USA is that it
attempts to provide a balance between innovation
and competition. However, the current practice can
and does result in redundant research since other
inventors have no knowledge whether someone has
filed a patent application on the same idea.
Companies have to put up with the US system
because, without US patents, they may be excluded
from the world’s largest market. Most big com-
panies favor the international first-to-file system due
to certainty. One benefit is in terms of the reduc-
tion of the threat of “submarine patents” or those
applications for major innovations which the Patent
Office has kept secret for decades because of inde-
cision about patent approval.When such patents are
granted to obscure inventors who claim to have
an idea first, they can torpedo other firms which
do not know that a patent on the same idea is
pending. As in the case of the microprocessor
patent, it took the Patent Office twenty years to
award a patent to Gilbert P. Hyatt in 1990. As a
result, North American Philips Corp. and others
had to scramble to obtain a license. Critics feel that
some inventors have manipulated the process by
continually filing revisions to the original patent
applications so as to extend such applications for
years or decades. These inventors then suddenly
claim patent rights to a widely used technology and
