Recommended - Firms: prosecution and nullity

Bronze - Firms: infringement

The patent attorneys and attorneys at law at Eisenführ Speiser draw on “in-depth knowledge of both technical and legal matters” to provide an inter-disciplinary, commercially focused service. One recent highlight was its representation of NPE Sisvel in patent infringement proceedings against Xiaomi – a high-profile matter to which attorneys at law Volkmar Henke and Tilman Müller and patent attorney Jochen Ehlers made vital contributions. “Amiable and well respected” among major communications players, Henke skilfully handles both infringement disputes and licensing mandates, with “a notably high success rate”. Müller’s remit encompasses patent infringement and nullity proceedings, SEP and antitrust-related issues, IP-related arbitrations and contract negotiation. Prosecution, litigation and transactions all fall within the purview of telecommunications and semiconductor expert Ehlers, who also comes equipped with FRAND and SEP know-how. Other esteemed patent attorneys on deck include electrical and telecommunications engineer Klaus G Göken – an IP strategist and litigation sage with rich industry experience from his previous career in the semiconductor field at Siemens and IBM; and life sciences whizz Manuel Söldenwagner, who recently represented fragrance and flavours company Symrise in a series of oppositions. “Manuel is efficient, organised and sensitive to client needs,” reports one happy patron of 10 years’ standing. “I have nothing but praise for his work, responsiveness and quality advice.”

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 for their internal procedures via remote access to their files, thereby considerably reducing their office expenditure for documenting IP activities.

Prosecutors – litigators – strategists

Traditionally strong in IP prosecution, the firm has gained a strong reputation in IP litigation over the past 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.

Eisenführ Speiser’s litigation teams of legal and patent attorneys have been involved in numerous litigations with multinational scope which led to landmark decisions, including the German Federal Court of Justice decision in Orange-Book-Standard and the first post-Huawei infringement decision of the Dusseldorf and Mannheim District Courts. The firm’s attorneys are also regularly engaged as independent IP evaluators.

Eisenführ Speiser’s approach to IP counselling is strongly business minded and considers intellectual property as an integral part of companies’ assets, to be strategically used within the framework of attaining corporate objectives.
