Creating value, protecting value

One of the region's largest patent attorney firms is located in Berg, near Ravensburg. The RavensPAT team of five patent attorneys, five patent engineers as well as 20 additional professional employees is specialised in all areas of technology. Founded in 1974 in Ravensburg, the firm experienced continuous growth and is now, due to its size, located in a stately  office building in Berg, just outside the gates of Ravensburg.

More than 90 per cent of the firm's clients are from the Mittelstand, the small to medium-sized enterprises that constitute the backbone of the German economy. Patent Attorney Herbert Otten describes the client structure as follows: “Our clients range from one-man operations to companies with 2000 employees.” “And the patents range from the spray gun to superconductors, as well as from agricultural machines to automotive technology.” The firm is especially active in the areas of mechanical engineering, electrical engineering, physical technology, as well as process technology, construction and medical technology.

Many customers are, naturally, from the region, but also from Berlin, Frankfurt, the Black Forest, Sauerland, the Austrian Vorarlberg region, and Switzerland. “We support these customers not only within Germany, but also in international markets.” Many cases are concerned with further developments in the industry. “These days, the Mittelstand must be extremely proactive and creative in order to survive,” explains patent attorney Markus Dobler. “This includes the systematic registration of patents at the companies. Patent strategies and a sustainable portfolio help enterprises successfully position themselves in a competitive environment.”

All five attorneys would like to emphasize that, in their work in the areas of patents, trade marks, design protection and licenses, an essential aspect constitutes being continuously able to understand and analyse complex, mostly technical, matters in order to obtain comprehensive legal protection for the client as effectively as possible. The attorneys  also count among their midst physicists, and also mechanical engineers, process technology experts, as well as electrical engineers. The approximately 900 square meter large firm is one of the largest in all of Baden Württemberg, measured not only by the number of employees but also in terms of client base.
