As Head of Trade Marks & Copyright, Abigail has been involved in the resolution of many disputes and remains committed to resolving conflicts by agreement rather than taking a purely contentious line.  She is also able to provide strategic advice on all elements of IP and how it can be used to grow a business, from funding, through due diligence and sale/acquisition.
