Intellectual Property


The law for a new Digital Republic, the creative freedom law, general data protection rules, the “trademark package”: the regulatory framework governing intellectual property law is changing at the national and EU level in line with new technologies and the extent of their impact on the issues in question. From contracts to patents via software and domain names, all aspects of this area are affected and this new legal environment requires greater expertise than ever, while the preservation and development of intellectual assets are taking on growing importance in a context determined by innovation. Whatever your business sector, it is vital to ensure that you own the technological and artistic works created by your employees and service providers, to guarantee their protection, to construct contractual exploitation frameworks that are secure from a legal and tax perspective and to adopt the means to tackle infringement and unfair and parasitic competition.

Our specialists benefit from significant experience in copyright, database law, advertising law, trademark law, drawings and models, domain names and patents, as well as unfair and parasitic competition law. Our team of 10 lawyers is therefore able to offer you a comprehensive service, from auditing of your company's intellectual assets to assistance and representation in relation to disputes via the registration and monitoring of your trademarks, designs and models (identification and analysis of precedents, national, EU and international registration, opposition procedures) and negotiation and drafting of your licensing, sale or coexistence agreements. Given the complexity of cases that often go beyond the strict framework of intellectual property, our experts work in close collaboration with their specialist lawyers in other areas (tax, customs, competition, etc.) to guarantee you the most effective support in all circumstances.

To achieve efficiency by taking a comprehensive approach, our experts draw on the vast CMS network with 150 specialist lawyers to handle international or transnational cases.

"CMS advises several major French luxury brands as well as foreign customers. Led by Anne-Laure Villedieu, the team deals with trademark, design and copyright files. They act both in consulting and litigation". Legal 500 Paris 2017
