IAM Patent 1000 (2022)

Gold – Firms: litigation and transactions: “A premier patent litigation firm, GEISTWERT is led by five highly experienced and entrepreneurial partners and a client-oriented team set on achieving their clients’ business goals. Their collaboration is exceptional, both in terms of content and results, and they are always focused and driven in their approach.” The stellar group recently represented TeleTan, the holder of a core patent of authentication processes in online banking, in an infringement claim. “In contentious proceedings relating to software development, Rainer Schultes, Constantin Kletzer and Alexander Schnider are goldmines of information”, and they all brought their A-game to the TeleTan dispute. Also on deck, Max Mosing and Juliane Messner have been working closely with Kletzer on behalf of Österreichische Post, the company responsible for postal service in the country, in technology transfer, licensing and monetisation matters.
