” I was introduced to Intellectual Property Law by chance, but it has given me a great deal of pleasure right from the start. The administrative handling in combination with the content, as well as operating on a national and international level, means that every day involves different activities. Looking after and safeguarding the interests of our clients, thinking along with them and achieving their objectives are paramount”.
