The procedure under
the PCT has great advantages for you as an applicant, for
the patent Offices and for the general Public.
Use of the PCT
saves effort—time, work, money—for any person or
firm (“the applicant”) seeking protection for an
invention in a number of countries.
Use of the PCT also helps
the applicant to make decisions about the prosecution of the
application before the various national Patent Offices in the
national phase of processing.
The saving arises primarily
from the fact that, under the PCT, the applicant files one application—the
international application—in one place, in one language
and pays one initial set of fees, and that this international
application has the effect of a national or regional application,
which, without the PCT, he would have to file separately for
each country or region.
You have up to 18 months more
than if you had not used the PCT to reflect on the desirability
of seeking protection in foreign countries, to appoint local
patent agents in each foreign country, to prepare the necessary
translations and to pay the national fees
You can rest assured that,
if your international application is in the form prescribed
by the PCT, it cannot be rejected on formal grounds by any PCT
Contracting State patent Office during the national phase of
the processing of the application
on the basis of the international
search report and the written opinion, you can evaluate with
reasonable probability the chances of your invention being patented
You have the possibility during
the optional international preliminary examination to amend
the international application and thus put it in order before
processing by the various patent Offices
The search and examination
work of patent Offices can be considerably reduced or eliminated
thanks to the international search report, the written opinion
and, where applicable, the international preliminary report
on patentability that accompany the international application
Since each international application
is published together with an international search report, third
parties are in a better position to formulate a well-founded
opinion about the potential patentability of the claimed invention
For you as an applicant, international
publication puts the world on notice of your application, which
can be an effective means of advertising and looking for potential
licensees.
