‘EIP is unstuffy and its staff are very personable. One rare aspect of EIP is that it is a firm both of solicitors and patent attorneys, the latter being highly relevant to (and important in) their work in patent litigation – the patent attorneys are usually heavily involved in the technical aspects of the litigation, providing essential input.’

‘I highly recommend Robert Lundie Smith. He is very hardworking, conscientious, and has a real understanding of the technical, legal and strategic aspects of the cases he is working on.’

‘Gary Moss is clearly an excellent patent litigator, and has done an impressive job of building EIP.’
