Dai Davis, Partner, Percy Crow Davis & Co and Chartered Engineer
Telephone: 07785 771 721


Dai Davis has been a specialist Information Technology lawyer for thirty years.  Having started his career at the Leeds precursor to international law firm Eversheds Sutherland, he became a partner and rose to become national Head of Intellectual Property law and subsequently national Head of Information Technology law at Eversheds.  He then headed the Intellectual Property and Information Technology Group at Nabarro in the North for over eight years.  He now works in his own specialist practice, Percy Crow Davis & Co.  Dai has a reputation as an Information Technology Lawyer both nationally and internationally.  Indeed, Dai has been consistently recommended in Chambers & Partners and Legal 500 directories for most of the last three decades.

Dai is a Freeman of the City of London through the WCIT (Worshipful Company of Information Technologists) and a non-executive director of FAST (The Federation Against Software Theft).

Dai specialises in non-contentious IT projects and advisory work.  He is involved in preparing standard terms and conditions, distribution, agency and other types of collaboration agreements, as well as web based trading terms.  Dai gives strategic advice as well as undertaking work that is of a more transactional nature.  He is involved in transactions of all sizes, including some major transactions, particularly IT outsourcing transactions in which the transaction value is high.

Dai acts for many suppliers of Information Technology solutions as well as buyers of Information Technology systems.  While most buyers for whom Dai acts are larger quoted and unquoted companies, or at least organisations of equivalent size, many of Dai’s IT supplier clients are owner managed businesses or privately owned.

He works with litigators on IT litigation matters.  Although he works with clients who are involved with all types of technology, Dai has super-specialist knowledge in two niche areas of Information Technology law: safety critical systems (such as those in the transport and chemical sectors) and IT security.  He has advised on cutting edge technology including the Internet of Things, Smart Meters, Digital Currency and Bring Your Own Device.

Dai has the added benefits of masters degrees: one in Physics and the other in Computer Science.  He is also an active member of the Institution of Engineering and Technology (“IET”).  His expert knowledge of technology has led Dai to become a sought-after speaker on technology law subjects.  He has chaired an International Standards legal advisory committee for over a decade and is a recipient of the International Electrotechnical Commission’s 1906 award.  He is a past Council member of the Society for Computers and Law.
