Philip Mansfield is a UK-qualified partner in the firm's London antitrust group, who splits his time between the London and Brussels offices. On recent matters he has actively participated in meetings with the EU Commission, the US Department of Justice (DoJ), the US Federal Trade Commission (FTC), the US Court of North California, South Korea's Fair Trade Commission (KFTC), the Japan Fair Trade Commission (JFTC) and China's Ministry of Commerce (MOFCOM) on merger, cartel and behavioural matters for various clients.

As part of his mergers practice, he regularly obtains regulatory approval for complex mergers and joint venture arrangements, particularly in the high-tech sector. Recent cases include advising Seagate on all non-US filings relating to its complex and high-profile acquisition of the HDD business of Samsung (complicated by Western Digital's attempted acquisition of HGST), which was named GCR "Matter of the Year 2012"; Sun Microsystems on its sale to Oracle, which was named GCR "Matter of the Year 2011"; and advising a third party on a successful intervention against Intel's acquisition of McAfee.

In terms of behavioural cases, he has an established track record of representing companies in successfully raising and defending behavioural complaints before the European Commission relating to interoperability (Sun Microsystems/Microsoft, PSI/IBM), bundling (Microsoft/Opera, Microsoft/Vista), patent pools (DVD6C/iODRA) and patent ambush (Micron/Rambus).

In cartels work, he is a regular speaker at the signature IBA/ABA cartel conference. Recent matters include advising Micron in its first EU settlement case (DRAM); advising parties in each of the rubber chemicals, EPDM, heat stabilisers, GIS, power transformer, LCD, CRT and auto parts investigations. OFT cases include the criminal and civil truck manufacturers investigation.

In antitrust litigation, 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.
