Our values
Four values. One promise.
Deep knowledge, strong networks, strategic acumen and growing together — the four dimensions that have shaped how we advise clients since 2005.
Deep knowledge
Our standard is to provide the best possible advice and substantive solutions for your matter. We stay current through regular scientific publications and active participation in leading conferences and academic events.
Strong networks
We've been a co-sponsor of the Heidelberger Wettbewerbstage since 2017 and are active in European IP networks. We also have a tightly knit national and international network of specialists across disciplines — and our clients benefit from it directly.
Strategic acumen
We don't just think in legal questions — we think in solutions, consequences and room to manoeuvre. We combine legal expertise with commercial understanding, tactical execution and long-term focus.
Growing together
Many of our mandates span years and even decades. Clients appreciate that we always put their commercial success first. We don't just provide legal advice — we help make strategic decisions with the long view in mind.
Behind every one of these values are people — meet our team
