The blog of the European Patent Lawyers Association (EPLAW) is interesting in many respects. For example it was the only place were, during Summer 2010, the opinion of the Advocates General of the European Court of Justice (ECJ) on the incompatibility of the proposed European Patent Court System with European Treaty Law was leaked. Recently, it was also the first place where the "non paper" of the Commission services about proposed solutions for a Unified Patent Litigation System was published. But here we want to focus on a series of posts on this blog, an exchange of views between two prominent members of EPLAW. Beside the opportunity to benefit from the take of of professional legal analysts about the opinion of ECJ on the incompatibility of the envisaged unified patent litigation system with European Union (EU) Treaties, reviewing this series of posts helps to understand what kind of patent system the "patent microcosm" hopes for, and what kind of alternative is the deepest fear of its members. Finally, now that Commission and Council have discussed some options about a unified patent litigation system, we can weight influence of the patent microcosm on EU institutions.
