Kümmerlein focuses on IT security issues as well as representing clients in disputes, most recently in connection with the defense against damages claims regarding a failed ERP implementation project; another core focus is on contractual support, such as software terms of use, hardware development and production contracts. The latter is a key strength of Kay Diedrich, who jointly heads the practice with Jens Nebel (IT law and data protection).
