Navigating the UPC: Insights from Year One
Join us on 10 July at 3:00 pm (CET) for an insightful online seminar as we delve into the inaugural year of the Unified Patent Court (UPC). Since its opening in June 2023, the UPC has changed the patent enforcement landscape in Europe and affected patent strategies for many companies. 12 months into its operation, we will analyse the trends emerging from the first decisions and the implications for overall strategies for patent en­force­ment. Dur­ing the webinar, you will hear from CMS patent experts (lawyers and patent attorneys) from several jurisdictions, including Austria, France, Germany, the Netherlands, and the UK. They will provide a comprehensive overview of the UPC’s first year in numbers and discuss the issues relating to preliminary injunctions, security for cost and enforcement. You will also hear about the pros and cons of opting out of the system and why you might want to reconsider this de­cision. Wheth­er you are a patent holder or a licensee, whether you have opted out of the Unitary Patent System or not, this webinar will provide valuable insights into the impact of the UPC on all companies with innovative activities in Europe.  Topics covered:  UPC’s year one in numbers – overview in stat­ist­ics Pre­lim­in­ary injunctions – Landmark decisions in the UPC’s first year Victory – what happens next? Should you revisit your opt-out decision?The webinar will be held in English language and attendance is free of charge.
