Press release dated January 11, 2023

BARDEHLE PAGENBERG is delighted about the development of the talent among its patent attorneys and attorneys-at-law and, at the beginning of the new year, appoints three former senior associates counsels at the Munich office.

Johannes Heselberger, Managing Partner: “Dr. Dominik Woll, Sebastian Horlemann, and Dr. Humphrey Morhenn have developed to become fundamental pillars of our firm thanks to their long-standing professional competence, passion, and commitment. We acknowledge this development by appointing them counsels, which consistently continues our growth.”

Dr. Dominik Woll

Dr. Dominik Woll advises German and international clients on issues of patent litigation and technology-related copyright law, competition law and antitrust law. He is involved in proceedings relating to patent and copyright infringements as well as competition law, frequently on a transnational level.

Dr. Dominik Woll primarily advises on various technical areas, especially in the fields of mechanical engineering, electrical engineering, and telecommunications. He has comprehensive experience in standard-essential patents (SEP) and their enforcement and/or defense against their enforcement, including FRAND issues. Additionally, he is an expert on comprehensive damages proceedings.

Dr. Dominik Woll additionally focuses on legal matters related to contractual copyright law, especially employee-related copyright law.

Sebastian Horlemann

Sebastian Horlemann is an attorney-at-law and commercial mediator who has been advising national and international clients in complex cross-border patent litigation for several years. His work includes both advising clients out of court and representing clients in patent infringement proceedings pertaining to various technological fields. Additionally, he conducts invalidity and opposition proceedings, asserting his clients’ interests.

Sebastian Horlemann has special experience in the fields of mechanical engineering, semiconductor technology, network technology, and medical devices. Another focus of his work is on telecommunication technology. Since he has contributed to various proceedings on FRAND licenses, Sebastian Horlemann also has comprehensive knowledge on standard-essential patents and their implications under antitrust law.

Additionally, Sebastian Horlemann advises clients in licensing negotiations, draws up expert opinions on infringement matters, and advises on contractual agreements, for example in the area of technology transfer by means of R & D agreements.

Dr. Humphrey Morhenn
German and European Patent Attorney

Dr. Humphrey Morhenn practices as a patent attorney on broad fields of mechanics, robotics, telecommunications, telecommunications engineering, think-film deposition technology, and physics. Due to his academic background, he has profound knowledge in the areas of semiconductor physics, photovoltaics, polymer physics, electron microscopy as well as x-ray and neutron technology. He contributes this knowledge to the prosecution and enforcement of patents as a member of our expert team.

A focus of his work is on patent infringement proceedings, especially regarding telecommunications (mobile communications, xDSL), cross-border proceedings included. In this context, he substantially handles the validity proceedings conducted in parallel, including nullity and nullity appeal proceedings before the German Federal Court of Justice. He benefits from this litigation experience when drafting and prosecuting patent applications, allowing him to obtain strong and valuable IP rights for our clients.
