Oppositions & appeals
Contentious Work
Our Oppositions and Appeals teams are also active in contentious matters, be that attacking or defending patents. The team has decades worth of experience in handling multi-party EPO oppositions and appeals, including collaborating with other opponents where advantageous, and effectively presenting arguments in the written and oral parts of the proceedings.
Freedom-to-Operate
In addition to securing patents for our clients, we also regularly advise on infringement risks arising from third party patent rights. We are able to conduct searches for relevant third-party patent rights that may be of relevance to our client’s commercial activities and advise accordingly on any infringement risks that we identify along with steps that can be taken to mitigate these risks.
