Doctrine of Equivalents: equivalence in Europe?

25Apr

Although the UK lately came into line with its own version of a doctrine of equivalents embracing Article 69 EPC and its Protocol, we still see significant differences between claim interpretation approaches across Europe. Here, our panel covering Germany, Netherlands, France and UK will look at comparative practices covering issues including discrepancies between novelty and infringement interpretation, adoption of the Formstein Defence and effects of file wrapper estoppel, based on a practical example. Spoiler alert: there’s no great equivalence between our approaches to the doctrine of equivalent!
