"On August 10, 1988, the Pharmaceutical Manufacturers Associations (PMA) filed a petition complaining of Argentina's denial of product patent protection for pharmaceuticals and discriminatory product registration practices. PMA alleged these practices are unreasonable and discriminatory and burden or restrict US commerce.
"On September 25, 1988, USTR initiated an investigation (53 FR 37668), and requested public comments in order to request consultations with the Argentine government. Consultations were held in Buenos Aires in December 1988 and August 1989. Public comments on section 304 determinations were requested on August 16, 1989 (54 FR 33809). On September 23, 1989, the PMA withdrew its petition on the basis of Argentina's willingness to modify its pharmaceutical product registration procedures, and to address constructively the issue of patent protection for pharmaceutical products.
