Firm Overview:
Founded in 1928 but with roots going back to 1900, Prinz & Partner is a boutique IP firm that provides specialist advice on every area relating to the protection and litigation of patents, trade marks and designs in Germany and internationally.
Prinz & Partner creates innovative IP solutions that help clients achieve their commercial objectives. The firm delivers those solutions with clarity and an uncompromising commitment to service and quality.
The firm has eight partners, 24 patent attorneys, attorneys at law and IP professionals. This size of team not only allows Prinz & Partner to provide the level of resources that clients need to manage their regular work but also the flexibility to react to any increases in the volume of work clients require during the busiest times.
Prinz & Partner’s patent attorneys are all members of the German Patent Bar Association as well as being authorised to represent clients before the European Patent Office and the European Union Intellectual Property Office in Alicante, Spain.
The firm’s attorneys are also qualified to manage trade mark and design portfolios and provide advice on all IP-related matters.
The firm’s special focus is litigation relating to all areas of patent, trade mark, domain, competition and copyright law. The firm is increasingly involved in combatting product piracy and trade mark infringement at trade fairs and, when required, organising border seizures for clients.
Prinz & Partner is the German member of AIPEX, a European alliance of independent IP law firms, with more than 200 professionals and offices in France, Germany, the Netherlands, Poland, and United Kingdom. The firm regularly holds seminars and workshops on current IP topics.

Main Areas of Practice:

Prinz & Partner draft and prosecute applications for German, European and international patents. The firm also has a great experience and the expertise to assist clients with the filing and prosecution of trade mark and design applications.
With regards to patent work, the firm’s patent attorneys have the scientific and academic background to cover every possible area of work, a list that includes but is not limited to mechanical engineering, electrical engineering, electronics, data processing, physics, chemistry, pharmacy, biotechnology and life science.
Prinz & Partner’s skills are not limited to drafting and prosecution. The firm can also demonstrate a long and successful history of enforcing and defending its client’s IP rights in infringement proceedings, oppositions, nullity actions and cancellation proceedings domestically and internationally.
Domestically, Prinz enforces IP rights before the German Patent and Trade Mark Office, the Federal German Patent Court and the Federal Court of Justice as well as before all civil courts. On an international basis, Prinz & Partner has defended its clients’ rights before the European Patent Office, the European Union Intellectual Propery Office and the European Court of Justice as well as in numerous cross-border litigation cases.
The level of success the firm has achieved for its clients has led to a large number of in-house patent counsels in major corporations continuously instructing Prinz & Partner to defend their IP rights in Germany and internationally. As an example, Dr Bernhard Pfleiderer currently acts as principal counsel for all IP matters for the European Central Bank.
To enable clients to maximise the value of their intellectual property, Prinz & Partner actively manages clients’ IP portfolios. This assistance involves developing complex strategies to help clients optimise their portfolio both in terms of their competitors’ market appearance and finding the balance between the costs they incur and the benefits their IP generates.
In order to provide clients with a comprehensive set of commercial IP services, the firm also conducts freedom-to-operate studies, provides opinions on questions of infringement, validity and due diligence proceedings and offers advice on domain matters, copyright and unfair competition. With regards to litigation, the attorneys of Prinz & Partner can enforce client’s general IP rights against infringement in Germany and abroad.

In the mechanical field, the patent partners Jochen Sties and Thomas Kitzhofer have a long-standing experience in national and cross-border infringement matters.
The firm has an outstanding reputation for taking direct actions against product piracy at German trade fairs. These actions have frequently led to the infringing products being seized and the booths of the pirates being successfully closed within hours of the trade fair opening.
