Bronze - Firms

Prinz & Partner’s history on the German trademark scene stretches back to 1928. Today, it stands out for its proficiency in litigation, though it also tends to an enviable collection of portfolios for players such as Rolex and Volvo. Head honcho Adrian Kleinheyer matches international portfolio management skill with contentious nous, and has been charged with all of Orange’s trademark matters both in and out of court. Equally versatile, Werner Sulzbach “is able to think very quickly and to envisage potential obstacles one might face in the process of getting trademarks. He is patient, cost-conscious and approachable whenever we have questions. The level of service is extremely high and Werner is extremely competent in both dimensions: knowledge and customer service”.
