World Intellectual Property Organisation (WIPO), and the USPTO. Technical
resources include the ACM Digital Library and the IEEE web site. Business
resources include Hoovers Online and the Financial Times. SurfIP is also

WIPO databases will have its title displayed only once in SurfIP. Below the
title of such patent documents, SurfIP will indicate the sources, where the
document can be found.
