Da Vinci Partners LLC

In Dr. Walter Maiwald, we have one of the most experienced and successful European patent and trademark attorneys available to meet our client’s needs. Our European team regularly handles direct European patent and trademark filings and related litigation for our clients. We're just outside of Zurich, centrally located near St. Gallen, the seat of the Swiss Federal Patent Court. Consequently, although international intellectual property is our specialty, local work is an important part of our daily practice.
