Case Studies - Successful Defence of a Patent for an Irish SME against two Opponents

Marie Walsh acted for an Irish SME food manufacturer, the Patent Proprietor at an Opposition hearing before the EPO in October 2017, at which there were two Opponents, one of whom was a large Multinational company. Marie argued successfully against attacks on the patent based on alleged added subject matter, lack of sufficiency as well as novelty against both the product and the process claims which were separately challenged on the basis of different prior art documents; and inventive step.  The successful outcome for Marie’s client meant that the Patent was maintained in the same scope of claims as granted despite attack by the two Opponents.
