What clients say about our work.
„ab&d Rechtsanwälte have been advising us on commercial law matters for over 10 years. We have always been able to rely on highly competent advice and great commitment, with economic considerations never being overlooked. The advice was given in a way that avoided litigation wherever possible – but when unavoidable, every resource was deployed, resulting in several court successes together.“
„Competence and a healthy attitude! We received a cease-and-desist letter back in 2010 and have had the firm by our side ever since. It is no exaggeration to attribute part of our success to their work – in trademark and patent proceedings as well as various court cases, we have always received highly competent advice with honest and realistic assessments.“
„Coming from another country to do business in Germany requires trustworthy individuals guiding you to success. And that's what Tobias, Norman, and his team represent for many of us, their clients. People willing to go beyond their daily-basis business and routine to be that lifesaving advice many of us are seeking for.“
„After founding Bone Brox GmbH, the lawyers at ab&d – especially Tobias Bystry – supported us hands-on in all matters of competition law and corporate law. Particularly noteworthy – they do not just negotiate and draft contracts, they always think commercially too – so we received not only legal advice but also valuable tactical and strategic input.“
Briefly describe your concern. We will get back to you promptly with an initial assessment.
