About

Provided by ARNOLD RUESS

Our team of dedicated specialists has worked on a multitude of cases, including several groundbreaking decisions which have been widely reported. Our patent litigation experience includes the following highlights:

  • Representing a leading pharmaceutical corporation in patent litigation in Germany
    and coordinating proceedings with 15 other countries. Our global network
     enables us to provide a one-stop-shop solution with IP specialists
    individually hand-picked for our every client’s unique needs;   
  • Shaping FRAND case law by, among other things, obtaining the first two FRAND
    judgments from the German Federal Court of Justice following the
    decision of the Court of Justice of the European Union (CJEU) in Huawei v ZTE (Sisvel/Haier); we contributed to shaping the courts’ awareness of hold-out tactics by only purportedly willing licensees; 
  • Being the tip of the spear in the ‘connected car wars’ by representing a
    global telecommunications client in multiple trial and appeals court
    cases including a CJEU referral against a global car manufacturer; we
    gained in-depth knowledge of the automotive industry, its self-image and
     common negotiation tactics of car original equipment manufacturers and
    suppliers;
  • Levelling the international playing field by obtaining the first-ever German anti-anti suit injunction (AASI) against  an attempted foreign anti-suit injunction; this AASI, which was copied in several other jurisdictions within a couple of months
