Across global jurisdictions, the extent of protection afforded by a patent is defined by the claims as read literally – or, under the Doctrine of Equivalents.  In the U.S., the courts seem to recently be taking a more expansive view on the application of DoE in finding patent infringement.  Meanwhile, across Europe, each jurisdiction has its own infringement test, making it difficult to predict the outcomes of infringement proceedings based on DOE.  This session will consider the current status of the Doctrine of Equivalents in the U.S. and across Europe, as well as the latest DoE developments in Japan.
