JUVE Patent

Wiltschek Plasser – Austria 2022

JUVE Comment

This Vienna IP boutique headed by two partners is among the firms with a strong visibility in IP litigation. The firm is active in numerous high-profile proceedings in trademarks and unfair competition as well as copyrights and patents. Although the small outfit is not a member of any formal international network, it is often involved in international patent cases, especially regarding pharma patents. Outstanding contacts among Austrian and international patent attorneys form the basis for this.

Alongside renowned veteran Lothar Wiltschek, rising star David Plasser has established himself in the market and is noted by competitors for his litigation success in fair trading law and trademarks. But the firm stands out for its very small size in comparison to competitors. This in no way diminishes the reputation of the two name partners but does limit the firm’s development overall. For example, WP is refraining from more actively expanding its prosecution practice for trademarks.
