Since the headline-grabbing merger between Haseltine Lake and Kempner & Partners in 2019, the resulting powerhouse has been earning rave reviews for its comprehensive patent offering. “Rarely does a firm put out such high-quality work product so consistently for such good value,” reports one client. “Haseltine Lake Kempner is creative, responsive and demonstrates the utmost professionalism, legal knowledge and attention to detail. In addition, the practitioners are wizards when working with specifications written for the US.” Global head of client services and former EPO examiner Simon Rees makes it his mission to build enduring relationships with clients and boasts wide-ranging technical capabilities spanning telecommunications, electronics and computer architecture. He has lately been serving the IP protection needs of new client UK Atomic Energy Authority alongside his colleague David Hammond, a versatile and client-focused attorney who spends the majority of his time handling innovative medical patents. His dual academic qualifications in chemistry and DNA technology mean he is always on top of the details in even the most complex cases. Other life sciences stars include Alex Rogers – a thorough and persuasive EPO oppositions ace; and the “dynamic and driven” Joseph Lenthall, a judicious manager of chemical and pharmaceutical portfolios who is likewise a familiar face at the EPO. Meanwhile, “brilliant and focused litigator” Richard Kempner routinely brings home the wins in court and provides bespoke, highly specialised advice.
