Trademarks, Business Signs and Domain Names
Our advice covers all the facets of cases regarding trademarks, domains and other commercial signs (company names, local signs, and the like). Our advice is proactive and we take our clients' commercial needs into consideration. We have worked with some of the largest companies in Denmark for many years and have a trusting relationship with these, as we help them protect and enforce their trademarks. We also continuously help foreign clients with the protection of some of the most well-known brands in the world.
We have many dedicated partners, attorneys, trademark attorneys and paralegals who can help you with the following issues:
- Identification of and strategic sparring on what you need to protect as a trademark or register as a domain
- Filing trademark applications around the world
- Commercialisation and/or use of trademarks (draft and review of licensing agreements)
- Disputes regarding trademarks, domains and other commercial signs
- Portfolio work, including optimization of your trademark portfolio, trademark renewals, etc.
- Buying and selling trademarks, domains and other commercial signs
We have represented our clients in a wide range of cases before the administrative trademark offices and courts in Denmark and the EU.
