| The Patent Cooperation Treaty
(PCT) |
|
|
During the late 1970s,
several international agreements were reached which allow a single application
to be recognized in a number of countries. The ARS Patent Culture Collection
is recognized as a depository for all of these agreements. The Patent
Cooperation Treaty (PCT) became effective in 1970 and was amended in 1978
and 1979, and has been signed by all industrially important countries.
The treaty allows an applicant to file a single application in a standard
format through the applicant's national patent office and have the application
recognized as a valid filing in as many PCT countries as selected. The
European Patent Convention (EPC), which is restricted to European countries,
became effective on October 7, 1977.

An implementation
of the concept on a worldwide basis, the Budapest
Treaty on the International Recognition of the Deposit
of Microorganisms for the Purposes of Patent Procedure
(more simply designated as The Budapest Treaty) signed
on April 28, 1977, provided that a single deposit
in an approved culture collection satisfies the patent
application disclosure requirements of all member
countries of the Union established by the treaty.
To date, 139 countries are signatories of this treaty
and 37 International Depositary Authorities, including
the ARS Patent Culture Collection, have been designated
throughout the world.
