Vossius & Partner has grown in prominence and is distinguished for its expertise in biotechnology and chemistry. The firm also works in sectors including pharmacology, physics, electrical engineering and mechanical engineering. Competitors collectively describe the firm as a leading practice with a strong team. "Quality wise they belong at the top," says one, adding: "Hans-Rainer Jaenichen is one of the leading biology lawyers in Germany without a doubt. He is a star. Paul Tauchner is a great advocate as well, a great speaker who can argue very well." The full-service law firm has been notably active in medical technology litigation. Thure Schubert, Axel Stellbrink and Georg Andreas Rauh advised Smith & Nephew after patent holder Kinetic Concepts filed a request for a preliminary injunction against the use of foam products for negative pressure wound therapy. The case involved worldwide litigation in the US, UK and Australia. On a separate matter, Schubert, Stellbrink and Rauh advised Trans1 in further medical technology litigation. Patent holder Trans1 obtained an ex parte preliminary injunction against the use of a new device that would be part of a new method to treat the human spine. The injunction was upheld and followed by the defendant filing a revocation action before the Federal Patent Court. The matter is important given the innovative and commercial importance of the product. A further example of recent work relates to design patent and utility model litigation. Paul Kretschmar, Elard Schenck zu Schweinsberg, Stefan Fickert and Rauh advised Avon Products in connection with a request for a preliminary injunction filed against Avon for design patent and utility model infringement.
