When Gilles Rubens founded Landmark at the end of 2003, he had already made a career as a professional trademark attorney.After finishing his studies in History and Dutch Law at the University of Utrecht, he started to work at the inhouse trademarks department of the pharmaceutical company Duphar.
Part of his professional career he worked at IP firm Markgraaf (now Novagraaf), where he gained experience in handling trademark portfolios of multinational companies like Speedo and Campina. During the last years at Markgraaf, he was not only working as an IP attorney but also as one of the Directors. Before he decided to start his own firm, he worked a few years for Knijff & Partners.
At Landmark Gilles can better put his ideas into practice about anticipation of the client’s needs, practical solutions of legal problems, transparency and cost-consciousness.
Already in his student years, Gilles devoted most of his free time to travelling around the world. He has not made a career as a historian, but history has become one of his other big hobbies, which is easy to combine with his passion for travelling.
