【簡介】
SurfIP (http://www.surfip.gov.sg) is a vertical portal that offers
convenient access to multiple sources in one search operation.

Patent sources include the European Patent Office, the UK Patent Office, the
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
linked up Web Search Engines that include Google, Northern Light, etc. so
that users only type in keywords once and can search 2 to 50
websources/databases at the same time.

SurfIP also provides aggregated search results for the patent databases
(i.e. a patent document which can be found separately in US PTO, EPO and
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.

Searching in SurfIP is FREE.
