A years'-long struggle ended Tuesday when the European Parliament overwhelmingly backed the creation of a unitary EU patent and patent litigation court system. The vote followed Monday's approval by the Council of Ministers. But hard feelings over a last-minute government compromise, and continuing concerns about whether the new regime will make patenting in Europe cheaper and more accessible to smaller enterprises, continued to rankle. The European Court of Justice (ECJ), meanwhile, appears headed toward rejection of a legal challenge by Italy and Spain, who have refused to join the unitary patent system.
