Alan has advised on all aspects of intellectual property across a broad spectrum of industry sectors in a career with Bristows of more than 35 years.

His experience also extends to standard essential patents and the consequent FRAND issues.

Alan has advised many prestigious clients in technically complex disputes. He has a particular interest in chemical matters but has advised on a broad range of technologies from small molecule pharmaceuticals to telecoms. Many of his cases involve an international element, and he is experienced in dealing with the relationship between UK and EPO litigation..
