Intellectual Property Disputes

Allen & Overy is well known for its precedent-setting intellectual property disputes advice. We represent clients worldwide, at the highest level, in the many different courts and tribunals key to IP matters.

A&O’s global IP team understands how to exploit the procedural and tactical possibilities that different forums offer, coordinating regional and global litigation and settlement strategies to achieve the right business outcomes for clients.

A firm technical understanding of underlying IP assets is crucial. Many of our team members have technical backgrounds and industry experience to advise with confidence in cases involving the most complex science and technology.

Antitrust issues and arbitration considerations are also increasingly important in IP disputes: we work with our top-tier antitrust and arbitration practices to deliver a seamless service.

Our multi-jurisdictional litigation experience covers all areas of IP, including:

  • Major patent litigation, including in the life sciences and technology sectors
  • Trade mark litigation at all levels
  • Trade secrets litigation, particularly in the finance and telecoms fields
  • Design and copyright litigation, often with an emphasis on digital rights

Our experience

on a claim in relation to the McDonald’s “I’m Lovin’ It” jingle, song and trade mark where we advised three McDonald’s companies, as well as EMI, Pharrell Williams and Sony.
