The Greenshoots Podcast by Appleyard Lees – episode 20: Doctrine of equivalents and its impact on patent infringement assessment in the UK

In 2017, the UK Supreme Court’s judgement of Actavis v Eli Lilly created significant change to the way patent infringement is assessed in the UK by introducing a formal doctrine of equivalents.

Four years on, Appleyard Lees partners and patent attorneys Adam Tindall and David Walsh, and senior associate and patent attorney Chris Mason discuss the impact the Supreme Court’s judgement has had on the outcomes of patent infringement hearings in the UK, and how this has affected patent owners and third parties.
