Intellectual property law in Romania has developed significantly in the period since the Romanian Revolution of 1989 because of the need to enforce various regional and international treaties and agreements, such as the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), the European Directives on Biotechnological Inventions, on Trademarks and Geographical Indications, and on Supplementary protection certificates, the Trademark Law Treaty, the Patent Law Treaty, and the European Union regulation on the Community Trademark, and the need to harmonize domestic patent law with the European Patent Convention (EPC) and with the European Union.
