She has also provided litigation support, particularly on cases where she has been handling related oppositions at the EPO.

A substantial amount of Sarah’s work is for US clients, prosecuting applications at the EPO and defending the resulting granted European patents in oppositions, as well as attacking third party patents. Sarah is a regular visitor to the US, particularly to the Bay Area. Sarah regularly gives talks on aspects of European practice, particularly relating to patenting of antibodies and opposition strategy.
