JUVE Patent rankings 2020

Ranking shows FRAND disputes shaping UK market

London is currently the hottest place for FRAND disputes in Europe, with boutique firms like Powell Gilbert and Bristows benefitting the most from a trend towards telecoms. As a result, patent firms with a weakness in these disputes hardly have a chance to confront the two market leaders. But for some challengers, pharma is still holding strong as a main business driver. Read our analysis around the first JUVE Patent UK rankings

The back and forth over Brexit is about to come to a head. The London patent community is resigned to a change. Around the High Court, the seat of the patent court, there is a general effort to maintain the status quo. Lawyers are looking ahead to their cases for next year. When the question of the prospects of UK patent firms arises, the mood is calm. Business is fine, and Brexit won’t change much, say many litigators and patent attorneys.

But JUVE Patent noted four major developments affecting the attractiveness of the UK patent courts during its research for the 2020 rankings. These could either be a major setback for patent firms, or propel them to unprecedented heights. It all depends on how the following scenarios unfold.

An end to Brexit drama

The Conservative Party has decisively won the UK election. Now Boris Johnson will have his way. The UK will begin the process to leave the European Union on 31 January. However, Brexit initially has no direct impact on patent law in the UK. The country remains a member state of the European Patent Office and its national patent legislation continues to apply.

But how will clients from the US and Asia continue to do business in the UK after Brexit? Will international clients continue to recognise the patent expertise of the High Court?

UPC or no UPC?

A speedy Brexit will have a direct impact on the UK’s participation in the Unified Patent Court. The UK has already ratified the UPC agreement. But whether the court actually opens its doors still depends on the completion of German ratification. Currently, a complaint to the German Constitutional Court is blocking the ratification process.

Recently, hopes that the UPC will launch within the next two years were stoked when Peter Huber, constitutional court judge and rapporteur in the complaint, announced a decision for the first quarter of 2020. Now with a hard Brexit on the cards, time is of the essence.

All eyes on the Supreme Court

UK patent lawyers are also waiting on a ruling from the Supreme Court in the Unwired Planet vs. Huawei case. The Supreme Court must decide whether the UK patent court is entitled to order a global FRAND licence on the basis of a UK patent. The court is also looking at whether it may set the licence fee for the patent. In 2018, the Court of Appeal largely upheld the 2017 ruling of Colin Birss. Within weeks, the High Court became the number one court globally for lawsuits involving standard essential patents and FRAND.

Mobile technology research company InterDigital, for example, turned to the London court when it sued Lenovo. SEP owners Sisvel, Philips and IPCom are also currently very active in suing mobile phone providers and manufacturers. UK patent lawyers are hoping the Supreme Court will confirm the two previous instances in the Unwired Planet vs. Huawei case.

Then the High Court could become the most important global court for SEP actions for FRAND licences.

If the court overturns Birss’ ruling, however, London would revert back to an outdated model of dealing with FRAND and SEP cases. The High Court would just be one of many courts for FRAND cases and its most important focus would again be pharmaceutical lawsuits. In patent law, this has been the London court’s traditional strength.

Staffing problems

Nevertheless, attractiveness of the UK courts is by no means secure. The promotion of High Court judge Richard Arnold to the Court of Appeal this summer, as well as the death of popular patent judge Henry Carr, means the High Court is facing a diminished bench.

Currently, Colin Birss is the only full-time judge at the High Court, the court of entry for high-volume patent litigation. Birss is supported by deputy judges. Most are experienced barristers from the specialised IP sets dotted around Holborn. The search for successors is in full swing, but suitable candidates are proving difficult to woo.

The High Court usually recruits its junior staff from the few specialised IP sets. But ever since the UK government cut the judges’ pensions, barristers are less keen to move up. If no successors are found, the High Court that will have a serious problem on their hands. But patent firms will also face a lack of clarity and a longer trajectory for UK litigation proceedings.

Bristows and Powell Gilbert lead litigation market

JUVE Patent’s research showed two highly-specialised law firms emerging as leaders in the London market. Bristows and Powell Gilbert are not unknown to the international patent community, but JUVE Patent was surprised to find them far ahead of persistent challengers Allen & Overy, Bird & Bird and Hogan Lovells. This is mostly thanks to their strength in both pharma and telecommunication disputes.

Certainly, Bristows and Powell Gilbert have leading individuals such as Brian Cordery and Penny Gilbert in their respective ranks. But both firms also boast a variety of older and younger litigators who enjoy a very good reputation in the market.

JUVE Patent, JUVE Patent UK rankings

According to JUVE Patent research, Bristows and Powell Gilbert are leading the UK patent litigation market.

More important, however, is their high profile in the most important cases before the London patent courts. Bristows, for example, represents SEP holders IPCom and Philips in numerous FRAND lawsuits, and is also defending ZTE against an SEP lawsuit from Conversant. The firm is positioned on the side of originator and generic pharmaceutical manufacturers, such as Janssen Science, Fresenius Kabi and Teva.

Meanwhile, Powell Gilbert was present alongside Huawei, Lenovo and Xiaomi in mobile phone cases. It also shone in pharma disputes, such as representing Actavis against Warner Lambert concerning pregabalin before the Supreme Court. It also worked with Biogen concerning Humira. With clients such as Boston Scientific and Edwards Lifesciences, Powell Gilbert is also strongly positioned when it comes to medical device patents.

Snapping at the heels

Allen & Overy, Bird & Bird and Hogan Lovells are the three main challengers to the leading duo. All are also highly active in pharma and telecommunication cases, although not quite matching the two market leaders for breadth of clients. In addition, their lawyers are not quite as present in the market.

But most importantly, each challenger is dealing with overcoming obstacles preventing them from being at the top of the market. Allen & Overy, for example, had to cope with leading partner Nicola Dagg and a small team of associates jumping ship to Kirkland & Ellis in 2018. For Dagg, the move was successful thanks to the strength of her European network in cross-border disputes. However, the remaining patent team at Allen & Overy is still recovering from the setback.

Hogan Lovells can count on a stable patent team, but one that is narrower at the partner level than the other two challengers.

However, the problems at Bird & Bird are most obvious for many observers. The once-leading UK team has not yet fully recovered from the loss of Trevor Cook, who moved to WilmerHale in 2014 to establish a UK patent practice for the US firm. In addition, the partners between 35 and 45 still operate too much under the market’s radar. The firm’s presence in the market was also affected by the fact that Nokia, its most important client, is increasingly shifting its litigation activities to Germany and is rarely active at the High Court.

Nevertheless, Bird & Bird has in Sisvel a stronger plaintiff at its side in SEP disputes. In pharma disputes, the firm is as solid as ever representing generics manufacturers.

Broad midfield

The third tier of the JUVE Patent UK rankings for solicitors gives a broad group of litigation practices. Either the firm has a balanced ratio of cases across a broad technical spectrum or, like Carpmaels & Ransford and Herbert Smith Freehills, an incredibly strong practice in pharmaceutical cases. In terms of work quality and lawyer reputation, both law firms even rival the market leaders in this field. However, they are barely present in mobile communication lawsuits.

This tier also contains two of the most noteworthy climbers of the past year. EIP is generally considered the best example of a former patent attorney firm successfully establishing its own litigation business. Clearly positioned on the side of NPEs in SEP disputes, EIP is currently acting in two FRAND litigation cases at the UK Supreme Court, namely for Unwired Planet and Conversant.

But Nicola Dagg’s move to Kirkland & Ellis grabbed the headlines over 2018/19. At Allen & Overy, Dagg was already a leading individual in the market. The speed at which she established herself and her team, with three solicitors made non-equity partners at Kirkland, was surprising. Lawyers at other firms describe Dagg as “assertive” and “acquisition-wise, very talented,” talents on which Kirkland has quickly been able to capitalise on. The Kirkland team is active for Xiaomi and Lenovo in SEP disputes and represents top names in the pharmaceutical industry such as Novartis, Pfizer and Regeneron. However, in some cases the Kirkland team is co-counselling alongside more established teams.

Given this rapid success and Dagg’s relatively young team, many competitors are wondering if Kirkland will be able to sustain the patent practice’s development.

WilmerHale is another US law firm that has quickly established itself in the UK market, building on its intensive relations with Apple in the US and the reputation of partner Justin Watts. He who joined the outfit from Freshfields Bruckhaus Deringer in 2017.

Towards a mixed approach

Like in Germany, and more recently in France and the Netherlands, mixed firms of patent attorneys and lawyers are in vogue in the UK. Marks & Clerk was a first-mover here many years ago; other firms, such as EIP and Carpmaels & Ransford, are successfully adopting this strategy.

JUVE Patent, JUVE Patent UK rankings

JUVE Patent ranks the top filing firms in the UK according to their most recommended technical areas.

However, none of the litigation teams from these firms have yet managed to catch up to the market-leading litigation teams such as Bristows or Powell Gilbert. EIP, for example, is generally strong in mobile communications, but hardly present in pharmaceutical cases. Likewise, Carpmaels & Ransford is considered one of the five or six outstanding law firms in Europe for life sciences. However, its litigators rarely appear in telecommunication disputes.

UK patent attorney firms are mostly present in patent filing throughout Europe and compete for work primarily with German prosecution firms. Law firms such as Carpmaels & Ransford, Marks & Clerk and Kilburn & Strode are among the most active before the EPO.

Barristers at the forefront

At 8 New Square, the barristers are consistently recognised for in-depth technical knowledge and impressive client base. The set works across all areas of patent law, and its QCs and juniors are present in some of the most important cases shaping the European patent landscape. This includes Unwired Planet against Huawei, and Pfizer against Hoffmann-La Roche. Furthermore, 8 New Square works in an array of emerging fields, such as medical devices.

Overall, the most recommended barrister in JUVE Patent’s research was Richard Meade. The renowned barrister described frequently as a “star” of the IP bar. It is his name, alongside that of fellow QC Daniel Alexander, most frequently touted as being perfect ‘judge material.’ The deficit felt on the judicial bench is hoped by many to be filled by highly-qualified and respected barristers such as Meade and Alexander.

8 New Square’s barristers are present in the UK’s central patent disputes in the UK. It received by far the most recommendations of all the UK’s IP-specialist barrister sets.

However, second-tier sets 3 New Square and 11 South Square are as close in reputation as they are in proximity. The former is particularly strong in pharmaceutical work, the latter in electronics and telecommunication cases. But clients and solicitors recommend both sets as offering the best barristers at the UK IP bar.

From both sets, barristers often frequent the higher court instances. 3 New Square, for example, has been on the side of Actavis, Teva and Mylan against Eli Lilly and ICOS over tadalafil at the Supreme Court. A three-strong team at 11 South Square defended Zyxel against TQ Delta over DSL technology at the Court of Appeal.

The UK bar also boasts other IP expertise, in sets which are less specialist but nonetheless have capacity for patent litigation. Blackstone Chambers, for instance, has impressive antitrust capabilities. But it is the top three sets which catch the eye of many teams litigating in front of the UK courts. Top names like Meade and Alexander are currently standing firm for now, however. Whether the top barristers are willing to make the leap from bar to bench will determine the near future of the UK’s patent courts.
