About
Provided by Marks & Clerk
Our market-leading patent litigation team makes us one of the most frequently instructed firms in this area. We are regularly trusted with the most complex and high-value matters because of the strategic, legal and technical excellence of our top ranked patent litigators. We are as comfortable conducting a single national patent action as we are co-ordinating a team of trusted partners in international multi-jurisdictional litigation.
We advise across the full spectrum of sectors, from life sciences to high tech and engineering. Our clients include many of the largest pharmaceutical, biotech and chemical companies in the world. They have diverse product and innovator portfolios including monoclonal antibodies, new chemical entities, vaccines, research tools, bio-processes, formulations and dosage regimes. On the high tech and engineering side we work with cutting-edge global companies including those specialising in software and electronics as well as those in more traditional electrical, mechanical and engineering industries.
Many of our specialist litigators have a science or engineering background in addition to top-level legal skills. Where additional and specialised technical expertise is needed we can draw upon the world-class knowledge of our patent attorney colleagues.
