WWL says

Nicolas Mosimann is “a well-regarded practitioner” among peers who rate him as “particularly adept at advising tech-driven start-ups”.


Nicolas Mosimann is partner at Kellerhals Carrard. His practice focuses on technology and intellectual property law (in particular copyright, trademarks and design rights), M&A, venture capital, corporate law and commercial law. He advises both Swiss and international companies and institutions on transactions (outsourcing, acquisitions, joint ventures, financing rounds) and technology projects (including IoT and blockchain-based platforms), research and cooperation agreements, commercial contracts and data protection. In addition to this, Nicolas specialises in advising and representing software providers and customers (from development to protection and licensing, including SaaS and open-source software). He is as dedicated to his clients in a transactional capacity as he is in his role as a litigator.
