Patent Search and Discovery Databases

A listing of  the more commonly used Patent discovery search engines (freely available to all) follows below. All registered patents (and many patent applications) are open-access documents, freely available via Internet in the public domain.
Note there are numerous other proprietary, specialised patent search products on the market (sold as subscriptions). QUT does not subscribe to any of these.  Nearly all QUT scholars and researchers will be able to satisfactorily discover the patents they need by using these freely available, search engines.
