Special Report: EPO Opposition Trends in the Life Sciences Sector


opps-report-1-1

Achieving success in oppositions at the European Patent Office is critical for any innovation-oriented business seeking commercial advantage and growth. Our Special Report into Opposition Trends in the Life Sciences Sector provides key insight into this exciting space. This report provides forensic insight into the EPO opposition process.

We published this report to help tackle the key questions our clients ask regularly. In spring 2019, we undertook 350 hours of research, analysing more than 5,000 opposition cases filed at the European Patent Office over the last ten years, studying the timelines for hundreds of oppositions both before and after the EPO’s opposition streamlining initiative. Our own proprietary data analysis tool, developed specifically for this research programme, enabled us to download and manipulate significant quantities of data, a task previously unmanageable when undertaken manually.
