Testimonials

Powell Gilbert has an industry-leading profile in UK TMT patent litigation. It is involved in pretty much all of the leading cases in this area, regularly acting for very large multinationals. Its involvement in the groundbreaking Unwired Planet v Huawei litigation is a good example of this.

Penny Gilbert is highly knowledgeable and widely respected- a great, and astute, co-ordinator of litigation.

Tim Powell is a tenacious and highly effective litigator who you do not want on the other side of a case.

Bethan Hopewell is resolute and determined.

Simon Ayrton combines excellent legal intelligence and insight with commercial strengths in planning and executing strategies in multijurisdictional disputes. I have worked with him for many years on dozens of cases and have seen first hand how much clients value his ability to see and plan all the many different facets of a dispute.

Zoë Butler is superb at leading and co-ordinating teams on the largest of cases. She is absolutely unflappable even in the most difficult situations, and brings integrity and honesty which clients really value.

Peter Damerell is probably the most analytically able lawyer I have worked with. On a very large FRAND case he produced a databook document for the court the like of which I have not seen before and which was incredibly impressive. He is also a determined litigator.

Tess Waldron is an extremely talented associate. She has an exceptional intellectual grasp of a case and produces excellent documents time and again. I have also seen her co-ordinate a very difficult matter to a successful conclusion in a manner that was very impressive indeed.

The firm: Powell Gilbert’s lawyers include some of the leading practitioners in the field.

This experience ranges from acting in some of the leading biotechnology patent cases to involvement in smartphone wars and FRAND disputes.

The firm has appeared in many of the most technically complex and legally challenging cases in the UK Patents Courts, including in the High Court, the Court of Appeal and the House of Lords/Supreme Court. Powell Gilbert was involved in the first patent case in the Supreme Court and in references to the Court of Justice of the European Union (CJEU) and the EFTA court, on the supplementary protection certificate regulation.

Diversity

We have great pride in our team and are committed to providing an open, honest and approachable atmosphere. Our people are our strength and fostering an inclusive work environment with equal opportunities is key to our ongoing success.

We aim to maximise the potential of all employees. In doing this we promote mutual respect and all of our people are seen as individuals, each supported and encouraged to achieve regardless of their gender, ethnic origin, nationality, marital or civil partner status, sexual orientation, religion or belief, age, disability or socio-economic background.

This commitment to diversity and equality is central to our recruitment process: we recruit on merit.

Corporate Social Responsibility

Mentoring programme – We provide mentoring to students aged 16-19 years in partnership with Queens Park Community School and Careers Academies UK. Our volunteers work with students over an 18-month period, providing personal and professional support to help the students achieve their academic and career aspirations.

The support includes mock interviews, CV and application form development and one-to-one tailored mentoring sessions. Originally started in 2011 by the partners, this has evolved to a self-sustaining initiative by the associates and support team with the majority of employees now involved.

Pro bono legal advice to a national charity – DEBRA is a national charity that supports individuals and families affected by Epidermoylsis Bullosa (EB). EB is a group of genetic skin conditions that causes exceptionally fragile skin to blister and tear at the slightest touch, for which there is currently no known cure. DEBRA focuses on funding research to change this, while supporting those living with EB to enhance their quality of life.

Pro bono legal advice to the Design and Artists Copyright Society – DACS is the UK’s leading copyright and collecting society for artists and visual creators. We work with the society by providing pro bono legal services to artists caught up in copyright and licensing disputes.

Charities – We have a very keen Charity Committee which regularly encourages participation in a broad range of events. Whether we are dressing up, baking cakes or putting on our running shoes, we’re always keen to get involved and we support some extraordinary charities. In recent years these have included DEBRA, Together for Short Lives, Jeans for Genes Day, the London Legal Walk and the Legal Bake Off, the Crisis Square Mile Run and Movember.

Everyone in the firm is encouraged to undertake their own charitable activities and initiatives. In addition, every year we make significant donations to our Christmas card charities. These are chosen by members of the firm and usually have special personal significance. Last year, we supported four charities: Woodland Trust, The Book Trust, Grit and Together for Short Lives.
