What we can do for you

Tackling illegal practices

If you are troubled by unfair or illegal trade practices, marketing and advertising, competition, promotional games of chance or a domain name dispute, or if you have discovered that others are trading imitations or parallel imports of your products or their packaging, Ploum will help you tackle this, e.g. by setting up a programme to combat counterfeit goods or parallel trade. Our experts include an EU trademark and design attorney as well as other specialists in trademark law, design law, copyright law, trade name law and marketing and advertising law. We will represent you in court proceedings, before the Netherlands Authority for Consumers and Markets or the Advertising Code Commission if the need should arise.

International support

Since the challenges facing businesses do not respect national boundaries, Ploum maintains a wide and reliable network of agents, and we cooperate with other lawyers and service providers on a daily basis all over the world. We are also associated with a number of organisations such as MARQUES (the European Association of Trade Mark Owners) and the International Trademark Association (INTA). In addition, we act as lead counsel for a large number of non-European clients and are therefore their first point of contact in the EU. We help them set up projects that may involve more than 50 different countries.
