Partner, Patent Attorney


Robert handles patent work in our chemistry team. His work is focused in the pharmaceutical chemistry sector, where he applies his over 25 years’ experience in providing commercially focussed strategic advice. His work spans the product and IP lifecycle, including invention capture, drafting, global prosecution, opposition and freedom-to-operate.

Robert drafted and globally prosecuted the patent portfolios related to two marketed oncology drugs, one of which is a blockbuster – six patents he has drafted and prosecuted are listed in the FDA Orange Book. His experience in working with new clinical entities right from discovery to patient and the associated commercial milestones makes him passionate about helping others with IP protection in the drug discovery journey. Robert particularly enjoys advising start up and spin out companies alongside his longstanding relationships working with patent attorneys at pharmaceutical giants.
