Marie-Paule VANDEBERG attended the Union congress 2017 in Sicily, from May 31 to June 3. She had the opportunity to meet a lot of colleagues from different countries, mainly from Europe. Discussions were held on the forthcoming European Court of the Unified Patent (UPC) with a panel of European judges. The patentability criteria were compared between the US, China and Japan. The evolution of the EPO's case-law has been discussed, in particular in relation to a new criterion "lack of credibility", often put forward by the examiners.
