Generic manufacturers operating in Ireland will welcome the recent introduction of legislation which enables them to conduct necessary pre-approval experiments without infringing the patent rights of the original manufacturer. The exemption is contained in new Irish regulations in the form of the European Communities (Limitation of Effect of Patent) Regulations, 2006 (the Irish Regulations) which implement certain sections of Directive 2004/27/EC (with respect to medicinal products for human use) and Directive 2004/28/EC (with respect to veterinary medicinal products).
