Respected media in the industry have traditionally counted us among the leading firms in IP.



Since the inception of the rankings in the "JUVE Handbook of German Commercial Law Firms", Lorenz Seidler Gossel has always been listed as one of the leading law firms in trademark law and design law. We were named "Law Firm of the Year in the Field of Intellectual Property" in 2006. 

  • The Munich IP law firm stands like no other in the market for a combination of the highest level of expertise in trademark and competition law and fierce representation in litigation. The attorneys are therefore feared by opponents, but they are valued by long-standing and well-known clients such as adidas, Gabor and ProSiebenSat.1 for this very reason. "One of the strongest IP boutiques," praises a competitor. (JUVE Handbook of German Commercial Law Firms 2023/2024)
  • The firm continues to be one of the most sought-after IP boutiques in trademark and competition law disputes as well as in strategic advice (including portfolio management). This is ensured by a high number of cases for large brand-name companies such as adidas as well as for renowned retailers. The firm's vehement commitment to client interests and its highly praised professional quality have long since become the hallmark of the entire firm. (JUVE Handbook of German Commercial Law Firms 2022/2023)
  • The IP-boutique is one of the entities which shape the market thanks to its traditional consulting approach, its renowned litigation practice and highly stable human resources in their team. Competitors describe the barristers-at-law as “tenacious” (JUVE Handbook of German Commercial Law Firms 2019/2020)
  • With its classic boutique approach, LSG impresses clients and competitors alike: “Highly competent”, opined one client; “An IP boutique with an outstanding approach to strategy, which is deeply anchored in the material”, praised a competitor. Another competitor: "they’re all very tough customers in the courtroom” (JUVE Handbook of German Commercial Law Firms 2018/2019)
  • "Solid as a rock, this leading firm in trademarks and unfair competition is standing its ground in the market. LSG offers the whole gamut of IP, but the lawyers are esteemed and feared for their vast litigation presence on the side of notable trademark holders such as Adidas - most recently against Nike concerning deceptive advertising for soccer shoes. Though the partners have enjoyed a loyal client base for years and are highly visible thanks to litigation work, the associates could increase their visibility." (JUVE Handbook of German Commercial Law Firms 2016/2017) 
  • " ...they are consistently recommended due to their exceptional legal expertise."

One client praised the team for its "many years of experience in the field of IP protection with in-depth and specific knowledge in individual aspects (JUVE Handbook of German Commercial Law Firms 2012/2013).
  • "Competitors praise the "legal quality" of the partners, but also continually stress the zeal with which LSG traditionally acts against their opponents. However, many clients have put their trust in the law firm for many years for just this reason." (JUVE Handbook of German Commercial Law Firms 2011/2012
