Daniel Sizer Email & Phone Number

I am passionate about technological innovation, in particular in the energy sector. I am a Patent Attorney and I am lucky to be able to work with innovators all over the world, both domestic and international, from individual inventors to multi-national corporations. I advise on a range of aspects of IP and enjoy the challenge of providing commercially-useful advice for my clients. I have extensive experience of patent drafting, prosecution, portfolio management, due diligence and managing third party IP risks. I also represent my clients before the Opposition Division and Appeal Boards of the European Patent Office.Marks & Clerk LLP is one of the world’s leading patent and trade mark attorney firms operating in 15 locations across the globe.
