Hatch‑Waxman Act Reshapes the US Drug Market
1984–1990sWhat Happened
The 1984 US Drug Price Competition and Patent Term Restoration Act, better known as Hatch‑Waxman, created data exclusivity for brand‑name drugs while allowing generics to rely on innovator data via abbreviated applications. It also formalised the ‘Bolar’ research exemption and 180‑day exclusivity for the first generic challenger, unleashing a wave of generic entry once patents and exclusivities expired.
Outcome
Brand‑name firms gained clearer protection and patent‑term restoration, while generic competition sharply cut prices after exclusivity ended.
Hatch‑Waxman became the template for balancing innovation and access, influencing later EU rules on data protection and Bolar exemptions.
Why It's Relevant Today
The EU’s pharma package is a new attempt at the same balancing act—rewarding innovation while turbo‑charging day‑one generic entry.
