Intellectual Property

United Kingdom

Our market-leading intellectual property team is the largest dedicated IP team in the UK. CMS was Awarded ‘Best Law Firm in IP, IT & TMT’ at the Trends Legal Awards in 2019. We house one of London’s most experienced and formidable IP litigation practices. Uniquely among large law firms, we also offer a significant patent, trade mark and design attorney team with true technical and legal expertise. And of course we help our clients in complex licensing and exploitation in the world’s most highly regulated sectors. Our team has earned multiple Band 1 ratings from legal directories.

Our team includes 130 lawyers, patent attorneys, trade mark attorneys, and specialist IP administrators and paralegals. This means our team is qualified to file complex patents in cutting-edge technologies at the European Patent Office; manage and enforce portfolios for some of the world’s biggest brand owners; and handle the most complex and technically demanding IP disputes.

We handle the full life-cycle of IP assets, including finding the best strategy for the creation, identification, registration and capture of assets, their realisation through commercial agreements and licensing, and their protection and enforcement through litigation and other dispute resolution.

A cohesive IP strategy, including both commercialisation and enforcement, will ensure that maximum value is obtained from your IP portfolio. Our team understands your business needs and objectives and has worked with some of the world’s best known brands. Our clients include organisations from banks to technology companies, pharmaceuticals to FMCG, and we help them realise their commercial goals.

We also advise on IP enforcement at all levels of UK courts (civil and criminal) and have experience litigating before the CJEU as well as many national courts of the EU and beyond in multi-jurisdictional disputes. Our patent and trade mark teams are experienced in dealing with proceedings before UKIPO, EUIPO and European Patent Office.  Costs can quickly escalate in contentious proceedings, so project management is key to our service, driving forward cases, narrowing issues, and managing other service providers.
