European litigation market

Europe’s leading national IP boutiques

When it comes to patent litigation, the leading IP boutiques across Europe are fierce rivals to the internationally integrated firms. National market leaders such as August Debouzy, Brinkhof, Bristows and Bardehle Pagenberg compete with large international patent teams for the outstanding cases in their jurisdiction. Read our in-depth analysis of the nine leading boutiques and their European strategies.

August Debouzy (France)

European presence and strategy: The IP practice of this national full-service firm is among the market leaders in the French patent litigation market. It has no offering in other European countries but remains strong representing some international clients in cross-border disputes, such as Huawei and Asus. The team has a good reputation for electronic and mobile communications disputes, as well as for pharma cases.

August Debouzy, JUVE Patent rankings

Two dual-qualified partners frequently represent their clients before both the national French courts and the EPO. If the UPC arrives, this experience will be a trump card that few other European firms can play. This makes August Debouzy an interesting partner for lots of international firms, especially those with a similar full-service approach.

But as part of a national full-service law firm, the patent team is more limited in its opportunities for close cooperation than pure IP boutiques.

European patent team size: 2 partners, 3 counsel, 10 associates (7 of whom are dual-qualified as patent attorneys and litigators)

Patent attorney practice: Paris

Leading individuals: Grégoire Desrousseaux, François Pochart (Paris)

Significant clients in recent cross-border disputes: Huawei (defendant) against Intellectual Ventures over SEPs; Asus (defendant) against Philips over European patents covering graphical user interfaces; Fresenius Kabi (claimant) against Amgen over Humira.


Bardehle Pagenberg (France, Germany)

European presence and strategy: Bardehle is on its way to becoming a top European firm. In Germany, this mixed IP firm remains a market leader in both patent litigation and filing. The firm recently strengthened its Düsseldorf office with a lateral hire who brings experience in SEP disputes. The Paris patent litigation team is well positioned in France and best known for its vast experience litigating for NPEs, such as IPCom. The German team is not active for IPCom but handles a major dispute for NPE Intellectual Ventures.

Bardehle Pagenberg, JUVE Patent rankings

Bardehle has a mixed litigation approach, internationally-oriented lawyers and offices at the key UPC venues of Düsseldorf, Munich and Paris. It also has a small Italian office in Verona, although no office in London. Currently, due to the uncertainty surrounding the UPC, there seems to be no plans to boost its presence in London.

However, if the court launches without the UK, it could be worth the firm considering an office in Amsterdam due to its focus on mobile communications.

European patent team size: 26 lawyers, 33 patent attorneys

Patent attorney practice: Munich, Düsseldorf

Leading individuals: Johannes Heselberger, Tilman Müller-Stoy (Munich); Julien Fréneaux (Paris). Patent attorneys: Christof Karl, Johannes Lang (Munich)

Significant clients in recent cross-border disputes: Intellectual Ventures (claimant) against Bouygues Telecom, SFR, Orange and suppliers such as Huawei over SEP (France) as well as against DTAG, Telefónica and Vodafone (Germany); IPCom (claimant) against Lenovo on anti-anti-suit and preliminary injunctions; 10X Genomics (defendant) against Bio-Rad over microfluidic chips; Amgen (claimant) against Regeneron/Sanofi over Praluent; SK Hynix and Hewlett-Packard (defendants) against Netlist over JEDEC standard; BMW (defendant) as well as TomTom and Robert Bosch (co-defendants of Daimler) in recent connected cars disputes.


Brinkhof (the Netherlands)

European presence and strategy: This IP boutique is a market leader for patent disputes in the Netherlands. The firm brought onboard litigation-experienced patent attorney Koen Bijvank three years ago, a step towards transformation into a mixed practice. This experiment has more than paid off. Bijvank has an excellent reputation for both EPO cases and proceedings before the Dutch patent courts.

Brinkhof, JUVE Patent rankings

Brinkhof is also highly respected in the European patent community. The firm has good relationships to numerous European patent firms. Brinkhof is also involved in a close relationship with UK market leader Bristows and mixed German firm Vossius & Partner. This connection was supposed to result in a strong alliance – or, as speculated by outsiders, potentially even an integrated firm for UPC cases. But given further UPC uncertainty, Brinkhof has reverted to its stand-alone strategy. Nevertheless, it still enjoys a close relationship to Bristows and Vossius.

With its pan-European litigation for Heineken, Brinkhof demonstrated that close alliances with other boutique firms can pay off without sacrificing independence. Vossius and Brinkhof also work side by side for Wiko. Such cooperation offers a credible alternative to the integrated practices of Hoyng ROKH Monégier or Hogan Lovells.

European patent team size: 14 lawyers, 1 patent attorney

Patent attorney practice: Amsterdam

Leading individuals: Rien Broekstra, Richard Ebbink, Mark Van Gardingen, Daan de Lange, Rik Lambers (Amsterdam). Patent attorney: Koen Bijvank (Amsterdam)

Significant clients in recent cross-border disputes: Heineken (claimant) against AB InBev over bottle-in-bottle technology; Xiaomi and Oppo (the latter public knowledge; both defendants,) against Sisvel over mobile phone standards; Wiko (defendant) against Philips over UMTS and LTE standards; Broad Institute in EPO proceedings concerning CRISPR-Cas9 technology (co-counsel with other European firms); Carl Zeiss (co-defendant of ASML) against Nikon concerning semiconductor manufacturing technology; Mundipharma (defendant) against Hoffmann-La Roche over anti-cancer drug Herzuma (public knowledge); Sandoz (defendant) against Icos over pharma drug tadalafil.


Bristows (UK)

European presence and strategy: This market-leading London patent-litigation practice continues its impressive development by retaining a raft of big-name clients in both telecommunications and pharmaceuticals disputes.

IP boutiques

Bristows, JUVE Patent rankings

As a London-based firm, Bristows might seem limited in its European reach. But its UK team often coordinates parallel proceedings across the continent. So far, this strategy is so effective that it has won the firm instructions away from the London courts. In some cases, such as for Heineken, the firm is running proceedings in Germany and the Netherlands alongside Vossius and Brinkhof. Bristows is well-known for having strong relationships to both firms. This relationship was supposed to lead to even closer cooperation in the event of a UPC.

But now, with the UK no longer part of the UPC and the patent court still uncertain, the three firms are concentrating on their stand-alone practices. Bristows now lacks direct access to the new patent system. Perhaps the firm will look for new alliances with other European patent firms.

European patent team size: 45 lawyers

Patent attorney practice: None

Leading individuals: Liz Cohen, Brian Cordery, Myles Jelf, Sophie Lawrance, Richard Pinckney (London)

Significant clients in recent cross-border disputes: Heineken (defendant) against AB InBev regarding beer keg technology; Philips (claimant) against Asus; IPCom (claimant) against Vodafone, Lenovo, Xiaomi and HTC; ZTE (defendant) against Conversant (all over mobile communications including FRAND); Fresenius Kabi (defendant) against Samsung Bioepis and Biogen regarding revocation of UK patent for biosimilar of monoclonal antibody, as well as coordination of European litigation.


Krieger Mes Graf v. der Groeben (Germany)

European presence and strategy: This Düsseldorf IP firm is one of the most active litigation outfits in Düsseldorf and among the German market leaders. The firm has a strong footprint in SEP and FRAND cases, acting mainly for patent pools and NPEs. On the other hand, when it comes to connected cars disputes, the firm is active for industry companies such as VW and some suppliers.

IP boutiques

Krieger Mes Graf v. der Groeben, JUVE Patent rankings

For a long time, the boutique has taken a wait-and-see approach to the potential UPC launch. Now, with the future of the court still uncertain, Krieger Mes has ruled out a merger with European firms. Instead, it counts on non-exclusive cooperation. This may limit its opportunities in cross-border proceedings.

Therefore, the firm must rely entirely on the huge appeal of its lawyers. Compared to other German boutiques, Krieger Mes is still seen less often in cross-border disputes.

European patent team size: 11 lawyers

Patent attorney practice: None

Leading individuals: Axel Verhauwen, Jochen Bühling, Gereon Rother, Michael Bergermann (Düsseldorf)

Important cross-border clients: Frequent litigation for MPEG LA and IPCom.

Significant clients in recent cross-border disputes: Texas Instruments against Broadcom over mobile phone chips; VW against Innovative Foundry Technologies over infotainment chips; Fipa against Samsung and LG over mobile communications; Classen against Välinge over laminate; Fresenius Kabi over biosimilar. Advice: VW Group in connection with connected cars licences.


Powell Gilbert (UK)

European presence and strategy: The London boutique is universally regarded as a market leader in the UK. It has a remarkable reputation for its litigation work, both at the UK courts and in major international disputes. For the latter, the firm often plays a coordinating role.

IP boutiques

Powell Gilbert, JUVE Patent rankings

The boutique is proud of its independent status. It relies on its strong relationships to other leading patent firms across Europe. Strong relations to US firms have allowed Powell Gilbert to specialise in pan-European coordination of cases for US clients.

Whether the firm will maintain this at such a high level after Brexit is a major strategic question.

Powell Gilbert emphasises that its leading role in coordination work grows organically out of its client relationships for work in the UK. Thus, such work is based on its technical and legal expertise with the international coordination work as added value. Depending on how the UK market and the role of UK courts develops over the next few years, Powell Gilbert may be forced into doing work which it has viewed as intellectually unattractive, i.e. European litigation with no UK proceedings, but where Powell Gilbert maintains a primary client contact to a mostly US client base.

If the UPC starts without the UK, Powell Gilbert’s major challenge will be how to ensure substantial knowledge in UPC law without direct access to the European patent court.

European patent team size: 28 lawyers

Patent attorney practice: None

Leading individuals: Zoë Butler, Peter Damerell, Penny Gilbert, Bethan Hopewell, Ari Laakkonen, Tim Powell, Alex Wilson (London)

Important cross-border clients: Frequent litigation for Edwards Lifesciences, GK, Huawei and Lenovo.

Significant clients in recent cross-border disputes: Huawei (defendant) against Unwired Planet on patent disputes and FRAND trial; Lenovo and Xiaomi (defendants) against IPCom in preliminary injunction and infringement proceedings over SEP and FRAND issues; Philip Morris (defendant) against British American Tobacco over heat-not-burn technology for e-cigarettes (all public knowledge); HEVC Advance (defendant) against Vestel on trial over abuse of dominant position including FRAND issues; Actavis (defendant) against Warner Lambert on second medical use of pregabalin patent; Biogen (claimant) on European litigation strategy for Humira; Edwards Lifesciences (claimant) in multinational dispute against Boston Scientific’s patents on transcatheter heart valves.


Quinn Emanuel Urquhart & Sullivan (Germany)

European presence and strategy: Once again, the German team of this US firm confirms its status as a leading outfit in German patent litigation. In other European countries, Quinn Emanuel has no team which matches its German office in terms of visibility and size.

IP boutiques

Quinn Emanuel Urquhart & Sullivan, JUVE Patent rankings

The major battle between Qualcomm and Apple illustrates how well Quinn Emanuel transfers major cases across the Atlantic, in order to try them before the German courts. As an exceptionally strong litigation practice in Mannheim and Munich, and with a good presence at the Düsseldorf patent court, Quinn Emanuel is well-prepared for such battles. This is as well as for a potential UPC launch. Additionally, the US firm has German offices in Hamburg and Stuttgart.

The firm has chosen not to have a comparably strong patents team in Paris. However, Quinn Emanuel recently strengthened its presence in London with a senior associate hire from Bird & Bird. Nevertheless, its strategy is based on partner Marcus Grosch’s extremely strong visibility, and its preeminent US practice. Most competitors are not convinced that this strategy will suffice to match up to Hogan Lovells or Bird & Bird in the assignment of cross-border cases.

European patent team size: 34 lawyers

Patent attorney practice: None

Leading individuals: Marcus Grosch (Munich, Mannheim); Johannes Bukow (Mannheim)

Important cross-border clients: Frequent litigation for Google

Significant clients in recent cross-border disputes: Qualcomm (claimant) against Apple (settled in 2019); Google (defendant) against Philips; IP Bridge (claimant) against HTC; BlackBerry (claimant) against Facebook, WhatsApp and Instagram (all over mobile communications); Daimler (defendant) against Conversant, Nokia, Sharp and Broadcom over connected cars; Netflix against Broadcom over video streaming; Pfizer in entitlement action over antibody; Bio-Rad (claimant) against 10X Genomics over gene sequence analysis; Välinge against OneFlor over floor coatings.


Rospatt Osten Pross (Germany)

European presence and strategy: This Düsseldorf law firm is part of the wider group of market leaders in German patent litigation. It conducts infringement and nullity suits primarily for clients in the pharma, biotech and mobile communications sectors.

IP boutiques

Rospatt Osten Pross, JUVE Patent rankings

The boutique is banking on its independence and close contacts in European litigation firms. Consolidating its good connections to UK firms Bristows and Powell Gilbert would be a good move, especially if the UPC should enter into force at one stage. Both these UK boutiques are being wooed by other German firms.

European patent team size: 12 lawyers

Patent attorney practice: None

Leading individuals: Hetti Hilge, Thomas Musmann, Max von Rospatt, Henrik Timmann

Important cross-border clients: Frequent litigation for Biogen, Samsung and LG

Significant clients in recent cross-border disputes: Samsung (defendant) against Fipa over G3 patent; LG (defendant) against OneButton and WiLan (all over mobile communications); Biogen/Samsung Bioepis (defendants) against Fresenius Kabi and Gideon Richter over Humira; Biogen against Forward Pharma on opposition over Tecfidera; CSL Behring (defendant) against Shire over active substance against auto-immune disease; Illumina (claimant) against MGI and Cenate over nucleic acid sequencing.


Wildanger Kehrwald Graf v. Schwerin & Partner (Germany)

European presence and strategy: This IP firm remains one of the most active litigation outfits in Düsseldorf and therefore a German market leader. With its expertise in SEP suits, Wildanger has gained a good foothold in international cases. But it is also present in German litigation for some cross-border life sciences disputes.

IP boutiques

Wildanger Kehrwald Graf v. Schwerin & Partner, JUVE Patent rankings

The boutique is banking on its independence and close cooperation with European litigation firms, alhough some outfits are being wooed by its German competitors. In order to handle more major proceedings, as well as to prepare for a potential UPC, Wildanger must consolidate its partnerships in European litigation. On a positive note, the partnership is constantly growing. The partners work on complex instructions in teams more regularly than other German boutiques.

European patent team size: 14 lawyers

Patent attorney practice: None

Leading individuals: Roland Kehrwald, Wolf Graf von Schwerin, Peter-Michael Weisse, Eva Geschke, Alexander Reetz (all Düsseldorf)

Important cross-border clients: Frequent litigation for IP Bridge and Genentech (public knowledge)

Significant clients in recent cross-border disputes: Sharp (claimant) against Daimler over LTE patent; LG (defendant) against Conversant over mobile communications; US chip manufacturer (co-defendant) against Intellectual Ventures over DSL patents; VoiceAgeEVS (claimant) over voice coding for mobile devices (all public knowledge); medical product manufacturer over heart valves; Swiss pharmaceutical company (claimant) over antibodies.

This article depicts those law firms which, according to JUVE Patent research, are among the market-leading patent litigation practices in one of the four main European jurisdictions. JUVE Patent takes into account law firms ranked in at least three of these jurisdictions, where the firms featured in one of the top tiers in at least one country (at least three JUVE Patent stars).

JUVE Patent published patent rankings in all of the following countries for the first time in 2019/2020:

Germany (October 2019)
United Kingdom (December 2019)
France (April 2020)
The Netherlands (May 2020)

All information on the law firms presented in this article refers exclusively to their position and analysis in these four rankings. Where more recent information was available (such as the number of lawyers or clients), it has been taken into account in the article. However, this information has no bearing on the firms’ ranking positions. Some of the law firms featured are also active in other European countries in which JUVE Patent has not yet conducted research.

The sections ‘important cross-border clients’ and ‘significant clients in recent cross-border disputes’ contain an overview of the respective law firm’s important clients. According to our research, the law firm represents these clients either in several offices or the firm is currently involved in important cross-border disputes in one or more countries.

Due to different rules on client confidentiality this list is not exhaustive, but simply a selection chosen by JUVE Patent.
