The annual Postgraduate Diploma in Intellectual Property Law and Practice alumni event was held on 2 May 2018 at the Royal Society.  Tutors and alumni who attended the event was treated to a talk by Lord Hoffmann on the different approaches to the issue of infringement by equivalence in UK patent law.  He began with the old days of pith and marrow, moved on to the all-inclusive purposive construction in Catnic, Improver and Kirin-Amgen and finished with a well-thought critique of the doctrine of equivalents that the UK Supreme Court introduced in Actavis v Eli Lilly. Special attention was given to Article 69 of the European Patent Convention which, as a backdrop, would have a limiting effect on interpretation of patent claims. Article 2 of the corresponding Protocol should, therefore, not be read in isolation. 

The Postgraduate Diploma in Intellectual Property Law and Practice is taught jointly by senior Oxford academics and senior practitioners from leading law firms and chambers.  It provides a top quality vocation experience for newly qualified solicitors and barristers embarking on a career in intellectual property law.
