Topic overview

Start with the big picture

IP provides time-limited protection for intangible creations to encourage pharmaceutical research and development. A patent generally requires novelty, non-obviousness, utility, and sufficient disclosure; pharmaceutical patents may cover an active ingredient, its forms, manufacturing methods, formulations, uses, or devices. Patent protection is distinct from regulatory data exclusivity, and both can affect when generic products enter a market. The topic introduces mechanisms such as the Hatch–Waxman framework, patent linkage, the Bolar exemption, and compulsory licensing under TRIPS. It also examines patent-term adjustments, evergreening, and the patent cliff. These mechanisms raise practical and ethical questions: how can systems support innovation while enabling timely access to essential medicines?
