He continues: “Volkmar Henke and Tilman Müller have longstanding experience in ambitious international high-profile proceedings, particularly in SEP and FRAND cases from the perspective of plaintiffs. We consider the fact that two top-class litigation experts from the first ranks of the sector both chose us and our market strategy right before the start of the UPC a distinctly lucky development for our firm.”
