  Philip Mansfield

Partner

London

Philip Mansfield is a UK-qualified partner in Allen & Overy LLP's London antitrust group, who splits his time between the London and Brussels offices. He has led meetings with agencies around the world on merger, cartel and behavioural matters for various clients, including with the European Commission, UK agencies, U.S. Department of Justice, U.S. Federal Trade Commission, U.S. Court of North California, South Korea's Fair Trade Commission, Japan Fair Trade Commission and China's Ministry of Commerce.

Philip regularly obtains approval for complex mergers and joint venture arrangements, particularly in the high-tech sector and was a winner of the Global Competition Review Matter of the Year in both 2011 and 2012 for merger-related cases. His experience includes advising: Sun Microsystems on its acquisition by Oracle; Symantec Corporation on the antitrust issues of its USD13 billion merger with Veritas Software Corporation and its acquisition of Verisign; Micron on the acquisition of a joint controlling interest in Inotera and various other acquisitions; Seagate on its acquisition of Samsung HDD and Xyratex; and Github on its sale to Microsoft.

Philip has extensive cartel experience and is a regular speaker at the signature IBA/ABA cartel conference. In 2016 Philip won Global Competition Review Behavioural Matter of the Year for the firm’s role on the European Commission’s credit defaults swap investigation. Matters include advising a party in the first EU settlement case (DRAM); as well as advising parties in each of the Fx, Rubber Chemicals, EPDM, Heat Stabilisers, GIS, Power Transformer, LCD, CRT and Auto Parts investigations. More recently Philip has developed extensive experience in advising financial institutions on a number of cartel investigations and Financial Conduct Authority market studies, including strategies surrounding the merits of making immunity/leniency applications to the UK Competition and Markets Authority and the EC and engaging in settlement discussions with the EC. Philip is currently guiding a major financial institution through the Financial Conduct Authority’s first ever investigation brought using its competition enforcement powers. He is currently advising clients on their defences to several separate follow-on damages actions before the English and German courts and has represented claimants in the English courts.

Philip has an established track record of representing companies in successfully raising and defending behavioural complaints before the EC and the UK courts relating to interoperability (Sun Microsystems/Microsoft, PSI/IBM), bundling (Microsoft/Opera, Microsoft/Vista), patent pools (Premaitha, DVD6C/iODRA) and patent ambush (Micron/Rambus).
