Assisting companies from all fields of technology, from pharmaceutical and medical devices to software and telecommunications, Christopher is an experienced litigator on strategic, cross-border patent disputes (including opposition work before the European Patent Office). He also litigates and arbitrates other types of intellectual property (trade mark, copyright, and designs), antitrust (including follow-on damages claims), pharmaceutical regulation, European Union law and commercial disputes. He is a creative and efficient problem-solver who thinks laterally across the breadth of his practice. He has taken cases before the First Tier Tribunal, the Upper Tribunal, the Patents County Court, the High Court, the Court of Appeal, the House of Lords, the Supreme Court, the European Patent Office, and the European Court of Justice.

Christopher is a Visiting Professor in Intellectual Property and Competition Law at University College London, and his 2007 practitioner textbook, "Parallel Trade in Europe: Intellectual Property, Competition and Regulatory Law," has been cited by the UK Supreme Court. He is committed to pro bono matters, including cases on recognition of change of gender for social security and tax purposes. Christopher is also chair of the firm's Diversity Committee for the London office.
