Kevin leads Corporate Commercial and IP team and Intellectual Property and TMT and practice areas.

Kevin manages clients through the development stage and the lifespan of their businesses, from start-up (or acquisition) through to exit. In addition to advising clients local to the office in the South East (in Kent, the rest of the Home Counties and London), Kevin acts for clients throughout the UK and abroad, including listed companies, often advising on cross-border transactions and dealing internationally with lawyers both on the other side of the transaction and on the same side in association (often working closely with local counsel in other jurisdictions, many through the Alliance of Business Lawyers of which Warners is a member).

Although Kevin’s practice has a focus on IP and IT, his practice is diverse and is both transactional and advisory. It includes; forming companies (including LLPs), partnerships and joint ventures (corporate or otherwise); corporate advisory (general meetings, financing / security, equity investments, corporate governance to directors and company restructuring / reorganisations); buying, selling and merging and demerging companies and businesses; advising on commercial contracts (often cross-border) from procurement to the renegotiation and dispute / resolution stages (where required); and advising on the development, protection and exploitation of intellectual property rights.

On the contentious side, Kevin regularly advises on contractual, shareholder / owner and intellectual property disputes (particularly copyright, trade marks and passing off, and the misuse of confidential information on the IP side).

As mentioned above, Kevin has particular experience in the technology sector (particularly information technology (IT) and software), but he also has detailed experience in several other industry sectors including media, telecommunications, retail (particularly eCommerce), professional services, manufacturing and agriculture (particularly fruit).

News & Insights

Faced with the daunting prospect of taking legal action against my business partner, I met with Kevin Sullivan and Jonathan Booton to discuss the available options to achieve the best outcome while bearing in mind the need to keep costs to an absolute minimum. Their sound advice and the competent way in which they guided me through an unfamiliar process were instrumental in achieving a much better resolution than I could have wished for. Throughout what was an extremely unpleasant and stressful time I was greatly reassured by their manifest integrity and professionalism. If I ever need the services of a firm of solicitors in the future I will certainly go to Warners first.
