Chris de Mauny

I am a patent litigation specialist based in San Francisco. I advise clients from a range of industries including tech, life sciences and sustainable technologies. I am licensed to practise law in England & Wales and registered as a Foreign Legal Consultant with the State Bar of California.

I advise on all forms of intellectual property litigation, principally patent litigation. In 2018 I was identified as a 'rising star' for patent litigation by Managing Intellectual Property and again in 2019. In 2019 I was referred to as a 'key lawyer' within Bird & Bird's London patent litigation team by Legal 500. In 2020 I was recognised as a 'Rising Star' for patents by Expert Guides, a peer-nominated international guide to lawyers, Legal 500 and MIP. Since becoming a partner in 2021 I have been ranked or recommended by IAM, MIP and Legal 500.

I was called to the English Bar in 2006 and practised in specialist intellectual property chambers until early 2011 when I joined Bird & Bird, known for its focus on technology clients. Bird & Bird is one of only two firms in the top ranking for IP by Chambers Global. In April 2024 I relocated to San Francisco to co-head Bird & Bird's office which brings our European and Asia-Pac expertise to US soil. Bird & Bird does not – and I do not - provide legal advice on Californian or any other US law.

I have represented a range of clients from multinational corporations to individual traders in disputes involving patents, trade marks and passing off, design rights, copyright, and rights in confidential and/or private information. My recent work has focused primarily on patent litigation in the life sciences, electronics and sustainable technologies.

I am a member of EPLAW, the UK's IP Bar Association, Chartered Institute of Patent Attorneys and AIPPI.
