In today’s knowledge economy, your intellectual property plays a key role in obtaining a competitive advantage. A cohesive strategy, including both commercialisation and enforcement, will ensure you get maximum value from your IP. With specialist IP lawyers throughout Central and Eastern Europe (CEE), we have worked with some of the best-known brands, from banks to tech and media companies, pharmaceuticals and FMCG companies, often across the region or in several jurisdictions.

Leading multinationals look to CMS for an integrated, cross-border service to meet their global needs and deal with global trademark portfolios, as well as specialist advice and representation in individual countries. Working with CMS gives you invaluable access to knowledge of the CEE markets and regulators, both locally and regionally. We work together with you to find the best solutions for your business.

The right brands will win the hearts and minds of your customers. The right patents will prevent others exploiting your ideas and provide a substantial barrier to market access. Copyright, know-how and designs also play a vital role.

We focus on key sectors relevant to you such as life sciences & healthcare, automotive, machinery, manufacturing, consumer products, financial services, and technology, media and communications. This means you get in-depth industry knowledge as well as legal expertise for the protection of your IP. If you are involved in a dispute, CMS’s dedicated contentious IP experts can guide you through the litigation process.
