All Swiss courts

Over the past two years, patent owners have frequently limited patents in suit during infringement proceedings in Switzerland. Two recent Federal Supreme Court decisions have illuminated how and at what stage in the patent proceedings limitations are possible. While bringing some long-awaited clarity, the recent case law also raises new questions and issues for patent owners to consider in determining their litigation strategy.
Is an animated lung on the display of a ventilator machine merely an unpatentable display of information or a technical feature that can provide an inventive step? For the first time, the Federal Supreme Court recently addressed the issue of whether such graphical user interfaces can be technical and affirmed a Federal Patent Court's decision.
The Federal Council recently published a preliminary draft of a revised version of the Patent Act which would introduce a fully fledged patent system. As is well known, Switzerland is not a member of the planned unitary EU patent system comprising a European patent with unitary effect and the Unified Patent Court, so a revision of the Swiss patent system could make sense in this context.
