Meeting virtually for an after-work chat in the European Patent Bar, judge Dr Matthias Zigann and attorney Grégoire Desrousseaux discuss “Adaptation of the description”. This requirement of the patent grant process at the EPO has provoked a variety of opinions amongst the
profession and even before the Boards of Appeal. They discuss the central importance of clarity for patents, especially in litigation, and evaluate the different positions that practitioners hold.

 Dr Zigann is Presiding Judge at the Higher Regional Court in Munich, as well as Presiding Judge of the Local Division (Munich) of the Unified Patent Court. Mr Desrousseaux is a French litigator, European patent attorney and partner at August Debouzy in Paris. The views of
the speakers are their own and not necessarily those of the EPO, nor of their courts nor chambers.
