J A Kemp Webinar: Priority Entitlement in Europe – Current Best Practice

14 January 2021

Challenging a patentee’s legal entitlement to claim priority is a common tactic in contentious proceedings in Europe.  If successful, the patent can be held invalid by the effect of intervening prior art.  This situation arose in a recent high-profile case before the Board of Appeal of the European Patent Office in decision T844/18.  A high-value patent in the field of gene editing (CRISPR) was revoked for lack novelty over intervening prior art following a loss of priority.  The case does not change the law in Europe.  Nevertheless, it provides an opportunity to reassess best practice for applicants.  In this webinar we will provide a concise review of European case law and practice in this area.  We will briefly discuss what went wrong and why for the patentees in T844/18, and we will outline practical steps and measures that can be taken by applicants to help safeguard priority claims in Europe.

Topics will include: 

  • The right of priority as a procedural right which is separate from substantive rights in the invention
  • A concise round-up of European case law and practice relating to priority entitlement
  • A brief summary of the Board of Appeal decision T844/18 and what lessons can be learned from the case
  • Practical advice to help mitigate against attacks on priority claims in Europe
