Intellectual property: patents (contentious and non-contentious) in London

Allen & Overy LLP

Leveraging its significant global footprint, Allen & Overy LLP’s London IP litigation practice has been making an impact in expansive, multijurisdictional patent litigation for global telecoms and technology clients. Neville Cordell ('an extremely sophisticated and astute lawyer'), Mark Heaney ('a ferocious appetite to ensure the best outcome for his clients'), 'class act' Mark Ridgway and the 'bright, extraordinarily charming and tactically astute' senior associate James Fox continue to be instructed on big-ticket FRAND and SEP litigation for household-name companies. Marjan Noor and senior associate Rafi Allos have secured numerous wins in the life sciences sector relating to UK patent revocation actions. The firm's dedicated transactional IP offering includes co-head Jim Ford, who acts for cutting-edge AI companies, and Nigel Parker, who is noted for handling strategic collaborations and M&A deals for pharmaceuticals and biotechnology clients. Bespoke in-house technology tools such as the A&O Collaborate platform — which senior associate Zoe Grant advised on the development of — assist with multijurisdictional patent coordination projects. Marc Döring has retired from the firm.

Les références

I can say without hesitation that Allen & Overy should undoubtedly be listed amongst the top three firms in this category. They have a whole suite of young, hard-working and strategically astute partners who have lifted the firm to the summit of IP litigation in this country.

Mark Ridgway – A class act from start to finish and everything in between. From initial advice through to conclusion of the trial, Mark should be your first port of call for any patent litigation.

Neville Cordell – An extremely sophisticated and astute lawyer.

Mark Heaney – Combines his incredible technical knowledge with a ferocious appetite to ensure the best outcome for his clients. You want Mark on your side for any high-tech litigation, you definitely don’t want him against you.

James Fox – Bright, extraordinarily charming and tactically astute. An outstanding associate who is destined not to be one for much longer!

The outstanding features of Allen & Overy are its multidisciplinary capabilities on an international scale.  A&O really do have direct access to specialists in all areas of the law on an international scale. This makes the firm outstanding in handling cases which have an international dimension and/or those which engage a range of legal issues outside of TMT/IP.

Marjan Noor is a stand out partner. She gets very involved in the case and manages at the right level. She is also very good at providing realistic budgets, which is refreshing and helpful for in-house counsel.

Friendly and responsive. Willingness to help. Sticking to timelines. Billing transparency – good information given in advance and then keeping to the costs given – this is important when the bills are relatively high.

Charlotte Tillett is very responsive and friendly with a can-do attitude – if she can’t help, she will direct me to a colleague that can.

Tom Collins is very thorough. Good input which my client found very helpful on a collaboration/MTA agreement where IP was an issue.
