Powell Gilbert – UK 2020

JUVE Comment

The London boutique is universally regarded as a market leader with a remarkable reputation for its litigation work, both at UK courts and on major international disputes, where it often plays a coordinating role. Relations to leading pharmaceutical corporations are particularly outstanding and the ties to the US have always been deep. The frequency with which the senior partners are recommended is remarkable – Penny Gilbert in particular provokes almost passionate approbation for her work in pharmaceutical cases, both in the London community and across Europe. However, that praise is often countered with the back-handed compliment that the reputation relies too heavily on the group of partners who set up the firm some ten years ago. Competitors – especially at larger international firms – like to point to what they see as a lack of strength in depth. In truth, this is more wish-fulfilment than based in reality, since anything but the most superficial analysis of the Powell Gilbert track record points to the opposite. The emergence of Bethan Hopewell and Peter Damerell in particular over the past two years demonstrates the firm’s ability to produce highly regarded patent litigators in the UK. The firm was involved in most of the major cases over the past year with the work on Huawei against Unwired Planet, Actavis against Warner-Lambert over Humira and Kymab against Regeneron at the UK Supreme Court. Its work for Biogen concerning Humira and for Chinese mobile device makers Lenovo and Xiaomi in their disputes with IPCom were especially prominent as well. With their work in the most important mobile communication disputes in the UK, the partners have proven their outstanding quality in this field. But the recognition also included criticism that the Powell Gilbert teams may not yet be optimally positioned at the interface between patent and antitrust law. Patent teams such as those at Bristows, Hogan Lovells and Allen & Overy are perhaps a step ahead of Powell Gilbert by working closely together with their own antitrust lawyers, says one in-house lawyer.This criticism remains an exception, however, since it was highly encouraging that it was through the work of some of the younger partners that the firm supplanted major international firms on major cases for international clients. This once again highlights one of the firm’s major strengths: its experience in coordinating complex Europe-wide litigation. Whether this will continue to be the case over the coming year is the major strategic issue for the firm.


Outstanding (international) reputation for litigation with deep bench of lawyers. Partners are at the forefront of developments in pharmaceuticals as well as telecommunications.

European strategy

The London-based boutique is proud of its independent status and 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 this will be maintained at such a high level after Brexit and the possible start of the UPC is the major strategic question facing the firm. Powell Gilbert likes to emphasise that its leading role in such coordination work grows organically out of its client relationships for work in the UK, and is thus 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 develop over the next few years, Powell Gilbert may be forced into intensifying work which it has viewed as intellectually unattractive, i.e. European litigation without a substantial UK aspect but where Powell Gilbert maintains the primary client contact to a mostly US client base. If the UPC starts without the UK, Powell Gilbert’s major challenge would also be how to ensure substantial knowledge in UPC law without direct access to the European patent court.
