FRAND/SEP litigation and licensing is of utmost practical importance in an increasingly connected world and grabbing the headlines globally. So, a good time for LESI’s Dispute Resolution Committee to provide a study comparing the current state of play (July 1, 2021) in the major jurisdictions for such disputes, namely Germany, the UK, The Netherlands, France, the United States, China and Japan. We are very grateful and thankful to all of our authors, being extremely busy top-tier patent litigators in their respective jurisdictions to have delivered a very practical and hands-on guide to Fair Reasonable and Non-discriminatory/Standard-Essential Patent (FRAND/SEP) litigation and licensing within a short time frame. Namely, many thanks to Prof. Dr. Tilman Müller-Stoy and Alexander Haertel, Bardehle Pagenberg, Germany, to Mary Foord-Weston and David Wilson, Carpmaels & Ransford, UK, to Rien Broekstra, Boukje van der Maazen and Daan de Lange, Brinkhof, The Netherlands, to Marie-Ange Pozzo di Borgo and Jean-Hyacinthe de Mitry, Gide Loyrette Nouel, France, to Doug Lumish and Alan Devlin, Latham & Watkins, USA, to Nongfan Zhu, KWM, China, and to Yasufumi Shiroyama, Anderson Mori & Tomotsune, Japan.
