To accomplish the study, the Commission subpoenaed documents and information from brand-name and generic drug manufacturers, and examined instances since 1992 in which generic applicants filed an application with FDA seeking to enter the market with a generic version of a drug product prior to expiration of the brandname drug products’ patents. An increasing number of generic applicants have sought entry prior to patent expiration. During the 1980s, only 2 percent of generic applications sought entry this way, but from 1998 to 2000, approximately 20 percent of the generic applications sought entry prior to patent expiration. ”
