IP Law

Practice area
Intellectual property stimulates innovation, creating corporate identity and brand identity. Plesner’s team is the leading adviser in Denmark when crucial rights are on the line and for finding the best way to navigate marketing through regulatory cross fields.

Innovation is the foundation for competitiveness and socio-economic growth. Intellectual property is an incentive and economic basis for investing in future developments. Balancing exclusive rights, on the one hand, and free competition, on the other hand, is complex. A creator must be rewarded for its contribution to the community. But in a market economy, it is also important to ensure that the creator is not the only one with reasonable access to using new knowledge and technology.

Intellectual property is also a question of communication and recognizability. It can be used to create corporate identity and to prevent others from free-riding on the expectations for the company and its products that it has invested in building.

Complicated rules apply to communication with customers and between competitors, and in order to ensure effective marketing it is important to be able to decode such rules. Because communication is often the prerequisite to success.

This also applies when the product itself is complex, including not least in relation to medicinal products and the rest of the life science industry. Companies in these industries further have to comply with additional regulatory requirements and restrictions, and it is crucial to be able to navigate such requirements.

Plesner's IP, Life Science and Marketing Law Team has the privilege of assisting large and medium companies with their most complex advice and disputes. Through long-standing and trusting relations, we have gained comprehensive understanding of our clients’ commercial reality. We conduct cases before all of the Danish courts, the Unified Patent Court and the Court of Justice of the European Union, and we assist our clients with the administrative handling of their rights and help them conclude agreements on such rights.
