Unrivalled success rate in EPO patent oppositions
No other IP firm has our depth of expertise over such a wide range of technologies
Where your freedom to operate is compromised, attacking the patent centrally through the EPO opposition procedure is one way to get other companies’ patents across Europe revoked. Marks & Clerk is one of the largest IP firms in Europe. Not only do we have people with detailed technical knowledge, but we are able to oppose or defend portfolios of dozens of patents simultaneously. And our success rate far exceeds that of the average European patent law firm.
Technical and legal expertise
At Marks & Clerk, we have a team of highly experienced oppositions specialists who will collaborate with your usual patent attorneys on opposition cases. This combination of expertise gives your opposition a far higher chance of success.
Our attorneys have deep understanding across many technologies including areas such as life sciences, software development, AI and 3D printing.
Our experience of working with searching tools and external searchers is invaluable in identifying relevant prior art, which forms the basis for many successful oppositions.
