Neil’s portfolio has evolved over his time at D Young & Co to be one that primarily concentrates on EPO oppositions and appeals, the provision of validity and infringement opinions, due diligence and litigation support, all in the field of pharmaceuticals. He still maintains expertise in advising small pharmaceutical companies in portfolio development and strategy, in particular in conjunction with due diligence for funding and stock market flotations. 

Neil has been successful in many oppositions and appeals in the pharmaceutical area, mainly acting for Teva Pharmaceuticals on patents concerning the second medical use of approved drugs, formulations, polymorphs and synthetic processes. In many cases, these cases have been linked to litigation in EU member states. He has additionally advised other pharmaceutical clients completing IP due diligence for mergers, project acquisitions and flotations. 

Neil’s background in biochemistry and pharmacology and his 20 years experience in patents, including time in-house at BTG and at Teva Pharmaceutical Industries Ltd in Israel, provide an ideal basis for this portfolio. 


"Neil is on top of his game. I cannot fault him," says a client in IP Stars, where Neil is recommended in his field (Managing IP).

Neil has featured as a leading UK patent attorney in the Managing IP 'Guide to the Leading Patent Law Practitioners'.
