We are a law firm with a long history.
Our patent law firm was founded in Berlin by Dr. Hans-Heinrich Willrath. It has been based in Wiesbaden, the state capital of Hesse, since 1949.
Pivotal roles in the continued successful development of the firm were played by the patent attorneys whose initials gave the company its name: Dr. Dieter Weber (until 2006), Klaus Seiffert (until 2009) and Dr. Winfried Lieke (until 2019). Our partnership currently comprises six patent attorneys: Dr. Matthias Achler, Dr. Jan Hiort, Dr. Maximilian Knaus, Dr. Manfred Köppen, Dr. Karsten Siebert and Dr. Roland Weber.
By steadily training further patent attorneys with the utmost care, we are not only securing the future of the firm but also ensuring that we can continue to offer our clients first-class support.
