The Federal Court of Justice recently addressed the scope of the so-called principle of concentration pursuant to sec. 145 Patent Act. If the patentee has filed an action, a second action based on a different patent against the same defendant is inadmissible in relation to the same or similar embodiments. The FCJ has now clarified that this does not apply to a second action based on the same patent.
