KATHERINE GREEN

Partner, Patent Attorney

Cambridge

Katherine specialises in EPO oppositions and appeals, particularly defending patents in complex opposition cases involving very large numbers of opponents.  Her defence of a patent protecting Xolair® against ten opponents in T 99/13 prompted an update of the EPO Guidelines for Examination emphasising the importance of assessing added matter from a technical and reasonable standpoint (read about this significant case in more detail).

Katherine advises on European prosecution strategies for many important patent families, particularly divisional strategies for opposed patents.  Katherine’s prosecution work includes advising on securing grant for the high-profile family of cases protecting CRISPR/Cas platform technology invented by Jennifer Doudna and Emmanuelle Charpentier.
