After finishing his PhD, Dr. Wolfgang Losert worked for two years at Degussa AG as a chemist before joining Hoechst AG. First as patent administrator and team leader and later as senior manager, he was responsible for the company’s patents, trademarks and licenses. Following Hoechst AG’s break-up, Wolfgang became manager for patents and licenses at Aventis GmbH and later joined Merck KGaA, where he was senior manager for patents and scientific services worldwide and coordinated teams in DE, CH, JP, CN, USA and IL.
Nach Auflösung der Hoechst AG folgte ein Station bei Aventis GmbH, ebenfalls als Leiter für den Bereich Patente/Lizenzen. Zuletzt war Dr. Losert bei der Merck KGaA als Leiter der weltweiten Konzernfunktion Patente und Scientific Services für Mitarbeiter in DE, CH, JP, CN, USA und IL zuständig.

Given his longtime experience as in house counsel, Wolfgang is particularly apt in negotiating and drafting technical contracts such as licensing, R&D, joint venture and joint development agreements as well as in matters of M&A and due diligence. His clients especially value his extensive know-how when it comes to linking IP with business strategy. In addition, Wolfgang also counsels on general questions of patent law as well as employees’ inventions.
