Further, the firm is increasingly involved in litigation relating to trademark and design matters and serves a growing demand of its IP strategy counselling, especially as regards extensive freedom-to-operate and IP landscape analyses.

IP innovator

Eisenführ Speiser was the first IP law firm in Germany to introduce an electronic filing system using fully electronic IP office processes. Since 2011, the firm’s clients have been offered innovative electronic support of their internal procedures via remote access to their files, thereby considerably reducing their office expenditure for documenting IP activities.

Traditionally strong in IP prosecution, the firm has gained a solid reputation in IP litigation over the last two decades and is routinely visible in international patent litigation campaigns for major national and international corporations. The firm represents clients before German and European courts and coordinates parallel court actions and licensing negotiations across multiple jurisdictions.
