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.
