World Trademark Review – WTR 1000

A potent force on the German trademark scene – with the ability to advise on everything from international filing strategies to disputes before the trademark offices and courts and licensing and contractual matters – Preu Bohlig has grown even further in stature over the past 12 months following the arrival of Jan Peter Heidenreich. The former Harmsen Utescher litigator shines in trademark suits, but also plays a hand in unfair competition disputes and the negotiation of distribution and licensing agreements. He brought with him an enviable list of clients, adding to the litany of names – diverse both in nature and in size – that rely on the firm to defend their rights. Alongside Heidenreich is veteran expert Astrid Gérard; whipping vast trademark portfolios into shape, fighting in infringement proceedings and drawing up watertight licensing and delimitation agreements all come naturally toher.

Preu Bohlig & Partner expanded the ties between the Hamburg office, where Daniel Hoppe advises on patent law, and the Munich office as the location of Peter von Czettritz and Alexander Meier, who cover pharmaceutical, competition and cosmetics law. The advisory spectrum includes regulatory and product liability issues as well as compliance issues. Von Czettritz is also one of the most experienced representatives in third-party opposition proceedings. Meier’s expertise includes orphan drugs and biological medicinal products, including advanced therapies. In January 2021, Tanja Strelow (pharmaceutical and food law, competition law) and Stephanie Thewes (HWG) were appointed counsels. In Hamburg, the simultaneous arrival of Jan Peter Heidenreich, formerly with Harmsen Utescher, strengthened the cosmetics and medicinal products advertising practice.

Legal 500 Germany 2022 – Unfair Competition

Unfair Competition

Preu Bohlig & Partner expanded its competition practice with the Hamburg addition of Jan Peter Heidenreich in January 2021, who formerly worked at Harmsen Utescher. Heidenreich’s expertise in contentious proceedings, including advertising, licensing and distribution agreements as well as antitrust issues, gave the firm, which is already known for its litigation practice, further weight in the market. The competition practice is integrated into the wider IP group, so that the firm is very well positioned for mandates with trademark, design and copyright elements as well as patent aspects. This includes, for example, product piracy cases and the defence against anti-competitive behaviour by competitors. In addition, the firm offers experience in media law and the protection of personal rights. Four practice group leaders are based in Munich: Astrid Gérard, Andreas Haberl, Jürgen Schneider and Ludwig von Zumbusch. Torben Düsing and Matthias Hülsewig in Düsseldorf and Christian Donle in Berlin complete the leadership septet.

Legal 500 Germany 2022 – Trademark


Preu Bohlig & Partner expanded its Hamburg office with the addition of Jan Peter Heidenreich, who worked at Harmsen Utescher until December 2020 and now fits in well with the firm’s focus areas with his advice on trademark, competition, copyright, cosmetics and medicinal product advertising law. The team’s antitrust and licensing expertise has also been strengthened with Heidenreich’s arrival. A particular strength is the trademark and design litigation practice, but one also offers many years of experience in the development and implementation of filing strategies in Germany, Europe and beyond. The hiring of new trademark lawyers in the Düsseldorf office around Torben Düsing and the traditionally strong soft IP locations of Munich with Astrid Gérard, Jürgen Schneider and Ludwig von Zumbusch and Berlin with Christian Donle make the medium-sized firm a well-positioned practice across Germany.

Patent prosecution

Preu Bohlig & Partner further expanded its work for pharmaceutical and medical device clients in 2020 with the help of the firm’s own regulatory experts, so that it has now created a clear fourth practice alongside the traditionally strong automotive, telecommunications and mechanical sectors. In the automotive sector, the team is particularly active for automotive suppliers in proceedings against competitors and for OEM manufacturers. In the telecommunications sector, the focus is on proceedings brought against collecting societies. The interface expertise between telecommunications and the automotive sector is put to good use in the area of connected cars. The main contacts are Christian Donle in Berlin, Daniel Hoppe in Hamburg, Christian Kau in Düsseldorf and Ludwig von Zumbusch in Munich as the respective office heads. The office in Paris is the responsibility of Konstantin Schallmoser. Two new counsels were appointed in January 2021: Martin Momtschilow in Düsseldorf and Christian Holtz in Hamburg.

JUVE Comment

Preu Bohlig’s patent team has an excellent market image across Germany thanks to its deep roots in litigation for Mittelstand clients. The team led by Christian Donle is always visible in mobile communications proceedings, with many for regular client Huawei. With litigation for Hewlett Packard in the suit by NPE Wsou, other partners are now appearing in high-profile cases.

Companies also rely on the team for proceedings of great economic importance in the pharma and medical products sector, among them Fresenius Medical Care Deutschland regarding hollow fibre spinning machines and Hikma Pharma concerning cancer drug pemetrexed. Preu Bohlig has intelligently used its well-established interface with regulatory pharma law to provide all-round advice, for example advising medical product manufacturers on licence agreements. The firm’s good reputation recently opened the door to work involving a medical product app. The success for Fresenius Medical Care at the Federal Court of Justice (Bundesgerichtshof) involving trade secrets for a manufacturing process for dialysis technology is proof positive that the medical product manufacturer chooses Daniel Hoppe and his team for complex proceedings.

Thanks to the success of laterals like Hoppe and Christian Kau the IP firm has managed to reinvent itself in recent years. The young team of partners is now tackling the next step and investing in associate training – a consistent strategy that should allow the firm to cope with the steady rise in work.

At the same time, the firm has nurtured excellent, informal relationships with patent attorney firms for years. Because of the trend towards mixed firms, pure patent attorney firms are increasingly involving the Preu Bohlig partners when their regular clients, especially from the German Mittelstand, need legal background advice or litigation. Clients praise the “superb advice and quick availability” of the Preu Bohlig partners.


Litigation with a broad technical spectrum, including SEP and FRAND claims.

European strategy

The German IP firm with strong roots in the Mittelstand opened its own Paris office a few years ago, through which it acquires and advises French clients. An unusual investment, but one that has so far paid off. Preu Bohlig frequently cooperates with numerous foreign firms within non-exclusive relationships. Because of its client structure, however, the firm is only active for Huawei in important cross-border cases.

Law Firm of the Year for IP

In this category, the JUVE editorial team awards prizes to law firms that are developing particularly dynamically in trademark, patent and competition law.

Here, the presence in important lawsuits, the support of high-profile clients in contract drafting and portfolio management as well as personnel development play a particularly important role.

iam Patent 1000

A mainstay of the German market for more than 60 years, Preu Bohlig is home to 30 attorneys at law working from four offices located throughout Germany and a fifth in Paris. Telecoms is a stronghold for the firm, which this year went out to bat for Huawei in myriad infringement and nullity proceedings against various NPEs. Leading the charge here is Christian Donle, who also lectures regularly as an honorary professor at a university in Berlin. This eminent mind proves a formidable opponent – one rival remarks: “Donle is one of the few lawyers I’m scared of, because he has brilliant ideas. He’s an exceptional character who makes me think.” Another big-name client at the firm is Hewlett Packard Enterprises, which cosmopolitan attorney at law Alexander Harguth is representing in a complex web of patent infringement suits. He is frequently on his feet at the EPO and the Federal Patent Court; network technologies are aspeciality.
