From Visaepatetens: European Patent Court Not Compatible With European Union Law, says European Court of Justice http://www.visaepatentes.com/2011/03/european-patent-court-not-compatible.html "The Court observes, first, that, *under that agreemet, the European and Community Patent Court is an institution which is outside the institutional and judicial framework of the European Union*. [...] To that extent, the *courts of the Member States* are divested of that jurisdiction and accordingly *retain only those powers which do not fall under the exclusive jurisdiction of the European and Community Patent Court*."Patent Court: the Commission welcomes the delivery of the Court of Justice's opinion http://europa.eu/rapid/pressReleasesAction.do?reference=IP/11/269&format=HTML&aged=0&language=EN&guiLanguage=en
