The 2026 edition of IAM Patent 1000 has been published, recognizing Eisenführ Speiser as one of Europe’s leading firms before the Unified Patent Court (UPC). The firm has been ranked Silver in the UPC category, reflecting its strong position in one of the most important forums for patent litigation in Europe.

The ranking highlights Eisenführ Speiser’s particular strength in UPC proceedings. Success before the UPC requires both outstanding technical expertise and sophisticated litigation capabilities. This is where Eisenführ Speiser’s mixed-firm model provides a distinct advantage: patent attorneys and attorneys-at-law work closely together in integrated teams, combining technical, legal and strategic expertise to develop effective litigation strategies for complex international patent disputes. Clients benefit from seamless advice and representation from a single source.

In addition to its UPC recognition, Eisenführ Speiser is also recommended by IAM Patent 1000 in several other categories: Prosecution and Nullity (Silver), Infringement (Bronze), Transactions (Recommended) and the European Patent Office (EPO) ranking (Silver).
