Intellectual Property

United Kingdom

Our market-leading intellectual property team is the largest dedicated IP team in the UK. 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 prosecution team with true technical 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.

Brexit and CMS UK’s EU trade mark and designs practice/EU Regulatory life sciences

CMS has moved its EU trade mark and designs practice to Poland, with all of CMS UK’s trade mark partners holding continuing representation and audience rights before the EUIPO and the Court of Justice of the European Union, as Irish qualified lawyers operating their EU trade mark business from our Polish office. This ensures that we are able to continue servicing our client’s EU trade mark needs and grow the practice further.

As a result, we will update the representation for all EU trade marks we manage to CMS Poland, (CMS Cameron McKenna Nabarro Olswang Pośniak i Sawicki sp.k). All other non-EU trade mark work will continue to be provided by CMS UK.

If you have any questions or require further information, please contact Sarah Wright, Louise Gellman or your regular CMS contact in our trade mark team.

In addition, Gareth Morgan and his team will provide EU regulatory advice in the life sciences sector from our Polish office. Please contact him if you have any questions.
