Moorcrofts LLP

Work Department



Andrew has over 25 years’ experience as a technology lawyer. He joined Moorcrofts in March 2000, shortly after the firm was founded.

He is one of the UK’s leading free and open-source lawyers, is a Fellow of the Free Software Foundation Europe and the Open Forum Academy, and is a visiting lecturer at Queen Mary, University of London, on Free and Open-Source Software. He has lectured on open issues globally at venues, including London, Paris, New York, Boston, Seoul, Helsinki, Stockholm, Dubai, Mangalia (Romania), Brussels, Amsterdam, Barcelona, Edinburgh, Oxford and Cambridge. He is also a visiting researcher at the University of Skövde, Sweden where he has co-authored papers whose findings have been adopted into Swedish government policy.

Andrew is on the core legal team for drafting the CERN Open Hardware licence, and has work has included some of the world’s leading free and open-source software companies and projects, including Canonical (Ubuntu) and CentOS (where he negotiated the business transfer to Red Hat).

He handles cloud computing and project agreements, including complex data protection issues, and has recently been involved in the rapidly expanding fields of open data and open hardware. As well as speaking on legal issues at the 2012 Open Hardware Summit in New York, he co-opened the 2014 Open Hardware and Data Conference in Barcelona (the world’s first legal conference specialising in open hardware and data).

Andrew’s skillsets cover Open Source Licensing, Technology Law, Commercial Law and Intellectual Property. He qualified as a barrister and was called to the bar (Inner Temple) in 1991, and has now re-qualified as practises as a solicitor in England and Wales. He is also an Irish solicitor (non-practising).


Andrew entered Churchill College at Cambridge University, on a scholarship to study Natural Sciences, and transitioned to the Law Tripos, so he has maintained a parallel interest in science and technology on the one hand and law on the other. Prior to studying for the Bar, he was a computer consultant (and accredited NeXT Developer), was involved in the original Statute Law Database Project and advised the Incorporated Council for Law Reporting on data storage on CD-ROM. After passing the bar finals, he was employed as a barrister by Winward Fearon & Co in London, a leading construction litigation firm, where he was one of the first lawyers to apply database technology to document indexing to large scale litigation. In 1993, after requalifying as a solicitor, he joined the long-established Midlands firm of Brethertons in their company-commercial department, and in 1996 he became the firm’s youngest ever partner. In 2000, after a brief stint at BP Collins in Buckinghamshire, he accepted an invitation to join the newly-founded Moorcrofts.
