Passionate by tradition

The firm’s history goes all the way back to the first half of the 20th century. It was originally founded by two independent patent attorney offices in Stuttgart, Ruff Beier and Partner as well as Wilhelm & Dauster which merged in 2001 to form the current office.

The firm currently has eleven partners from a variety of disciplines and a support team of 30 employees. Together we support clients in the areas of patent law, trade mark law, design law and directly related fields of law.

What drives us

We are patent attorneys who are passionate about what we do. We are especially proud of our client base, which we support and represent with our vast experience and unparalleled commitment. Many of our clients have been relying on us for years.
