Marius Klötzer is Associate with our firm. He specialises in intellectual property law and, in particular, patent and trademark law.

The firm’s patent practice is recommended as a “well established and powerful team” with “strength and depth” in Legal 500, “in particular for difficult patent proceedings where the team meets highest standards in timing and quality” and “whose briefs are ‘a miracle of structure and precision and at that written to the point and a pleasure to read'”. The patent practice is further continuously recommended as one of the global top 1000 in IAM Patent 1000 (“The team does a wonderful and very detailed job. Its members are very meticulous and able to navigate complex scenarios and uncertain jurisprudence”). Chambers quote clients: “The lawyers are very good, with the experience to know what the real issues are in a case and focus their efforts there. They are creative and go the extra mile. You get quick responses and great answers.” and “It is a high-quality, successful firm with a very good track record. The partners are always on top of the case.”

The firm’s trademark practice is considered to be among the top 1000 worldwide by WTR 1000. ARNOLD RUESS is also listed for trademark and design law in “Germany’s Top Attorneys”, a ranking published by the news magazine FOCUS, for IP overall in Chambers Europe 2014 (“a respected player”) and in Managing Intellectual Property’s IP Stars Ranking.
