UNDER THE WORLD TRADE ORGANIZATION AGREEMENTS
AND THE NORTH AMERICAN FREE TRADE AGREEMENT
INTRODUCTION
Prior to the
Uruguay Round of the General Agreement on Tariffs and Trade (GATT) multinational trade
negotiations, the GATT did not cover intellectual property rights. The Uruguay Round,
which resulted in the creation of the World Trade Organization (WTO), also produced the
Agreement on Trade-Related Aspects of Intellectual Property Rights, including Trade in
Counterfeit Goods (TRIPS). Among other things, TRIPS contains provisions dealing with
patents, trademarks, copyright and industrial design.
Similarly, the
Canada-United States Free Trade Agreement did not at first cover intellectual property
rights; however, these rights were subsequently protected in Chapter 17 of the North
American Free Trade Agreement (NAFTA).
These notes
will outline the provisions of TRIPS and NAFTA that have implications for the protection
of patent rights for pharmaceutical products in Canada. Since the texts of the relevant
provisions of both agreements are similar, references will be made to the relevant NAFTA
provisions with the corresponding TRIPS reference following in parentheses.
PROVISIONS OF NAFTA AND TRIPS
Among other
things, Article 1709(7) of NAFTA provides that patents shall be available and enjoyable
without discrimination as to the place of invention, the fields of technology or whether
the products are imported or produced locally (TRIPS Article 27(1)).
Under Article
1709(2) of NAFTA, a country can exclude from patentability those inventions: (i) whose
commercial exploitation must be prevented so as to protect public order or morality
(including the protection of human, animal or plant life or health) or to avoid serious
prejudice to nature or the environment; (ii) that involve diagnostic, therapeutic and
surgical methods for the treatment of humans or animals; and (iii) that are of plants and
animals or that are essentially biological processes for the production of plants and
animals (TRIPS Article 27(2)).
Article
1709(5) of NAFTA provides that the owner of a patent has the right to its exclusive use
and the right to prevent other persons from making, using or selling a patented product
without the owners consent (TRIPS Article 28). The term of protection of a patent is
to be at least 20 years from the date a patent application is filed or 17 years from the
date a patent is granted (NAFTA Article 1709(12)). Article 33 of TRIPS provides for a term
of protection of at least 20 years from the date of a patent application. Article 1709(12)
of NAFTA also provides that the term of a patent may be extended to compensate for delays
caused by regulatory approval processes.
Under both
NAFTA and TRIPS, a country may provide limited exceptions to the exclusive rights
conferred by a patent, provided the exceptions do not unreasonably conflict with the
normal exploitation of the patent and do not unreasonably prejudice the legitimate
interests of the patent owner (NAFTA Article 1709(6), TRIPS Article 30). In addition,
NAFTA Article 1709(10) (TRIPS Article 31) states that a country can allow for the use of a
patent, other than the use allowed under Article 1709(6) (TRIPS Article 30), without the
consent of the patent owner, provided the conditions set out in the Agreement apply. Some
of these conditions are:
TRIPS, NAFTA AND COMPULSORY LICENSING OF PHARMACEUTICAL
PATENTS IN CANADA
Compulsory
licensing is a mechanism to curb the monopoly power of a patent. A compulsory licence
forces the patent owner to license the invention to which the patent applies to others, in
return for a royalty fixed by the government.
In 1969, the Patent
Act was amended to permit compulsory licences to import medicines into Canada. Among
other things, the amendment provided that the Commissioner of Patents was to issue
compulsory licences to import medicines and to fix the royalty for such licences unless
there was good reason to deny the application. The Commissioner had little discretion in
granting licences. In arms length purchases, royalty rates were set at 4% of the
selling price of a drug in its final dosage form.
Compulsory
licensing has been used extensively in Canada for pharmaceuticals. The ability to obtain
licences to import and to sell copies of patented medicines fostered the establishment of
a number of generic drug manufacturers who produced and sold lower-priced alternatives to
the drugs produced by brand-name companies. The generic sector also advanced after
provincial programs were set up to cover senior citizens and recipients of social
assistance for drug costs and after certain legislation began to permit pharmacists to
fill prescriptions with the generic equivalents of higher-priced patented medicines.
Pressure from
pharmaceutical manufacturers and a desire to make disparate intellectual property laws
more uniform have fostered a world-wide trend to restrict the use of compulsory licensing.
While they do not completely prohibit compulsory licensing, NAFTA and TRIPS restrict its
use. As noted above, WTO and NAFTA member countries are permitted to provide limited
exceptions to the exclusive rights conferred by a patent, provided that such exceptions do
not unreasonably conflict with the normal exploitation of the patent and do not
unreasonably prejudice the legitimate interests of the patent owner. In addition, where
the laws of a member country allow the subject matter of a patent to be used without the
authorization of the patent owner, there must have been efforts to obtain the
authorization of the owner on reasonable commercial terms and the patent must be used
predominantly to supply the domestic market of the member country authorizing the use. The
requirement for authorization, however, can be waived in the event of a national emergency
and both the authorization and the domestic market requirements can be waived where the
use of a patent is permitted to remedy an anti-competitive practice.
In January
1992, the federal government endorsed proposals emanating from the Uruguay Round of the
GATT multinational trade negotiations that eventually resulted in TRIPS. Because these
proposals envisaged a compulsory licensing system that was much more restrictive than the
regime operating in this country at the time, Canada was obliged to end that regime.
In June 1992,
the federal government moved to implement the TRIPS provisions on intellectual property by
introducing Bill C-91, which became the Patent Act Amendment Act, 1992.(1) Passed by Parliament in 1993, the Act eliminated the
general compulsory licensing of pharmaceutical products and thus ensured that the owners
of pharmaceutical patents would be protected from generic competition until their patents
had expired.
Under Article
1720(6) of NAFTA and Article 70(6) of TRIPS, a country was not required to apply the
conditions for the issuance of compulsory licences contained in Article 1709(10) and
Article 31 (restrictions on the issuance of compulsory licences) or the requirement that
there be no discrimination in the enjoyment of patent rights to compulsory licences issued
before 20 December 1991 -- the date on which the draft version of TRIPS became public.
This ensured that all compulsory licences issued prior to 20 December 1991 would continue
after TRIPS and NAFTA became effective.
Canadas
ability to treat pharmaceutical patents differently from patents for other inventions and
its freedom to reinstate the pre-Bill C-91 compulsory licensing regime for pharmaceuticals
are restricted by the provisions of TRIPS and Chapter 17 of NAFTA. Compulsory licensing is
permitted, however, provided the licences are issued in accordance with the conditions
outlined in NAFTA and TRIPS.
