In its Solvay/Honeywell judgment (C-616/10) of 12 July, the CJEU decided on several important issues regarding the Brussels I Regulation. Those active in international commercial litigation, particularly patent infringement proceedings, will be interested in this case. The questions in Solvay concern the application of several ‘Brussels I’ rules of jurisdiction to cross-border patent infringement proceedings. The CJEU gets the chance to clarify some questions-left-open related to the 2006 cases GAT v. LuK (C-4/03 ) and Roche v. Primus (C-539/03). Unfortunately, the ruling in Solvay itself also leaves several questions unanswered. I wonder especially whether it was necessary for the CJEU to ‘reformulate’ the questions put before it. I’m afraid it looks like the ‘reformulation’ has obscured the view of what is really going on here.
