The European Commission has published a Communication highlighting the need to improve the EU’s patent system, most notably by intstituting a European patent. At the moment, patents are protected at a national level, which makes patent protection in Europe considerably more expensive than in the US or Japan. The existing system of patent litigation in the EU also entails the risk of multiple patent litigation in several countries, leading to high costs for companies and lower levels of legal certainty. The Commission calls for the institution of a European patent – an idea recently abandoned due to disagreement regarding the applicable language regime – as well as improvement of the existing system of patent litigation.
