  • Expertise
    • IP litigation

      Representing clients in infringement proceedings has always been a key area of expertise at FPS. For decades, notable rights holders have entrusted the judicial assertion of their rights to the experienced FPS lawyers. FPS is often involved in the investigation of infringement cases as well as the inspection and preservation of evidence in advance. We also support our clients in border seizure cases. Representation is provided in all areas of IP law before the relevant courts and agencies.

    • Media/press law

      Media law regulates the use, distribution and production of media content such as radio, television, print media and online media. Press law is a part of this and deals with framework conditions of the press, including freedom of the press, editorial independence, personal rights, media liability and the right of reply. FPS advises media companies on legal matters relating to freedom of expression, including advice on media content and legal representation in proceedings involving the right of reply, injunctive relief and compensation for damages. We possess industry knowledge and offer advice on typical media contracts, cross-media collaborations and freelance authors. We also support Internet platforms in the areas of copyright, consumer protection and data protection. In the event of online legal violations, we successfully cooperate with law enforcement agencies.

    • Sports law

      Sport is a global growth market with a considerable volume of sales. FPS possesses wide-ranging expertise and experience in matters concerning the protection and exploitation of valuable marketing rights (through shirt or perimeter advertising, for example) and in the field of sports sponsorship and the marketing of sporting events. We advise clubs, sponsors, sports rights marketers and event organisers, but also individual athletes, player agents and coaches. The focus here is on providing legal advice on corporate, tax, licensing and contract law matters, with a particular focus on sport-specific aspects. FPS also offers interdisciplinary advice and legal project management for large-scale projects such as the construction or conversion of stadiums and arenas (including in the field of public procurement law), the corporate structuring of sports clubs and other contractual arrangements.

    • Pharmaceutical advertising law

      FPS has been advising medium-sized and larger pharmaceutical and medical device manufacturers on advertising issues for a number of years, assessing advertisements, websites, brochures, giveaways and other promotional material, for example, and addressing the associated issues of the admissibility or misleading nature of information featured in scientific statements, among other things, in the light of the Health Services and Products Advertising Act (HWG) and the Act Against Unfair Competition (UWG). In this field, FPS represents manufacturers in out-of-court processes involving competitors and competition associations and especially in disputes before the civil courts.
