Your specialists for health, pharmaceutical & medical device law


Healthcare is OUR DNA

Pharmaceuticals, medical devices, dietary supplements, and healthcare services are our world. We are pleased to advise and represent you and your company in this demanding sector – with legal precision, industry expertise, and a keen eye for your objectives.

  • Communication in the right context

    Our roots lie in medicinal advertising and competition law. From there we have consistently developed our range of advice. If you want to know what you are legally allowed to communicate about a drug or medical device, it is not just the individual statement that matters. The context is important: What do you want to convey, who do you want to address and what role does your product play in this? That's why we take into account both the medical-scientific background of the product and its market environment in our analysis. Because the crucial questions cannot be answered in isolation. Medicines advertising law, regulation, market access and reimbursement as well as liability law always intertwine.

  • Structuring collaboration in a legally secure manner

    We also assist you with healthcare compliance matters, such as structuring collaborations with physicians, pharmacies, medical facilities, and payers. In doing so, we involve your teams and share our expertise through practical training sessions.

    We monitor regulatory and health policy developments at an early stage, enabling you to anticipate what lies ahead for your company and make the right decisions in good time.

  • Consulting with litigation experience

    For us, advisory services and litigation go hand in hand. Should a dispute arise, we represent your interests before civil, social, and administrative courts – including in preliminary injunction proceedings. At the same time, the experience gained from court proceedings shapes our day-to-day advisory work: it enables us to identify risks at an early stage, realistically assess arguments, and develop a sound strategy in collaboration with you.

  • So you can focus on your business

    Good legal advice does more than just answer legal questions. It creates clarity, outlines alternatives, opens up scope for action, and relieves you of work.
