Experience and Trust
STORK BAMBERGER can look back on a history spanning over 130 years – a history built on our unwavering focus on successfully securing your innovations through patents, trademarks, or designs.
As experienced patent attorneys, we dedicate our expertise to the comprehensive preparation and filing of applications and provide strategic advice on the consistent enforcement of the resulting rights – in Germany, across Europe, and worldwide.
We represent your intellectual property rights before German, European, and international authorities (DPMA, EPO, EUIPO, WIPO). Additionally, we maintain a network of personally selected patent and law firms around the world, enabling us to collaborate effectively when needed. This ensures comprehensive protection for your innovations across all key markets.
Moreover, we assist with international patent applications (PCT), international trademark registrations (IR trademarks), and design applications under the Hague Agreement, enabling cost-efficient protection in multiple countries through a single filing.
The roots of STORK BAMBERGER trace back to the late 19th century.
Over the past 130 years, the firm has accompanied the evolution of intellectual property protection as well as the technical, economic, and societal developments of the times.
The first known owner of the firm was Camillo Resek, a graduate engineer and patent attorney. As shown in an announcement by the Chamber of Commerce published in the Lübecker Volksbote in 1913, he gave public lectures for an interested audience on the topic of “Inventions, Their Protection, and Their Commercialization.”
Back then, the firm was located in the Holstenhof, a historic Gründerzeit building in Hamburg’s Neustadt district that still stands today. In 1926, the firm was taken over by partners Koch and Dr. Pogge. After the early passing of Dr. Pogge, Mr. Koch continued to run the firm together with Franz-Werner Clodius, who had joined at the same time. The firm’s new address was Rathausstraße 29, in the heart of Hamburg.
From 1937 onwards, Franz-Werner Clodius continued to run the firm independently under the name “Clodius Patent Law Firm.” His client portfolio at the time reflected the rich commercial tradition of the Hanseatic city. In the field of patents, he advised clients from industries such as fish processing and precision casting, while in the area of trademarks, he primarily served trading companies as well as import and export businesses.
During World War II, when the building next to the town hall was destroyed by bombs, Mr. Clodius moved the office to his private house in Grubesallee in Hamburg-Rahlstedt without further ado.
In 1968, Heinz Peter Wenzel took over the firm from Franz-Werner Clodius, where he had previously completed his training as a patent attorney. The clientele expanded rapidly. In 1974, Heinz Peter Wenzel and Heinz-Dieter Kalkoff, who ran a patent attorney’s office in Witten, joined forces to form a supra-local partnership.
From 1978 until 2011, the firm was known as Wenzel & Kalkoff. As structural change progressed, the range of clients also changed. The firm was expanded and strengthened by the addition of further partners, Ute Stork (1998) and Stephan Bamberger (2000).
In 2009, the firm moved from the premises in Grubesallee, which had become too small in the meantime, to the current firm building in Hamburg.
Since 2012, the partners Ute Stork and Stephan Bamberger have continued to run the firm as STORK BAMBERGER Patentanwälte and have expanded the range of practice areas. Jan Quellmann – who has been with the firm since 2007 – joined STORK BAMBERGER as a partner in 2017.
Since 2024, Dr. Alina Schiecke has been part of our team as a patent attorney candidate. Together, we are proud that a large number of our clients have been working with our firm for many years – some even for decades. The continuity in our patent law advice is valued by both our clients and ourselves as an essential part of our business relationships.
