How do you help clients?

I engage with clients early to discuss their IP, and provide thorough pre-filing assessments and strategic advice, advising not only whether protection is available but what will be the likely scope of protection, whether this is commercially attractive and whether the client position can be improved. 

My work involves drafting and successfully prosecuting patent applications across the life sciences sector in multiple jurisdictions, with a good filing strategy leading to robust IP positions.   

I have a proven track record in co-ordinating large global patent portfolios for the firm’s clients, including a number of large academic portfolio’s spanning multiple territories.

I am regularly invited to give talks about intellectual property adapting and tailoring the advice to suit my clients’ needs. This includes providing talks for University Technology Transfer Offers as part of their structured training programmes, as well as regularly being on-site at universities to provide advice.
