Patents are an essential part of protecting technical innovation. They ensure research and development expenditure can be translated into real business benefits.


At Mewburn Ellis, we are renowned for securing strong patent rights in the UK and across Europe. We are able to draw on our wide network of foreign associates to secure patent protection in every corner of the world.

Highly skilled technical experts

Our patent attorneys work in all technical areas – life sciences, chemistry & materials, engineering, electronics, computing & physics. With many of our attorneys holding a PhD in their subject, we truly understand the technical background fundamental to the preparation or prosecution of an effective patent application.

We enjoy an excellent reputation in life sciences and the pharmaceutical sector. But our expertise extends well beyond these disciplines. Our comprehensive team of experts are confident in drafting and prosecuting patent applications across all technical fields.

Many of our attorneys have considerable expertise and success in oppositions at the European Patent Office, both defending and opposing granted patents for our clients.  In addition our dispute resolution team  has particular experience and are well placed to advise on contentious patent matters in the UK, and for multi-jurisdictional disputes.

We are ready and able to advise clients on all aspects of the Unitary Patent (UP) and the Unified Patent Court (UPC) including the pros and cons of  opting out of the UPC.

We are equally at ease whether we are working with corporates, IP attorneys, start-ups or universities. We are conscious that different clients have different requirements. We tailor our approach to match their needs.
