The second edition of this very practical book provides an authoritative and detailed commentary on the centralised European patent grant opposition and appeal procedures set up under the European Patent Convention as well as on the applicable European substantive patent law. It has been substantially revised and takes into account the large number of changes that have taken place in European patent law since 1992. It is an invaluable source of information in this rapidly evolving area of law, especially with the anticipated future development of the EU and new legislation surrounding this. * The text is supported by extensive references, both to the EPC and to Board of Appeal decisions, making it easy to use and practical for your everyday needs.
