What is a patent?

A patent is a contract between the state and an inventor by which a temporary monopoly is granted in return for disclosing all details of the invention. For researchers, patents are an important source of scientific and technical information. Patents are often the earliest source of information on a new technology.

How do I determine if a patent on "topic x" exists?

To determine if a patent exists search the following databases:

Derwent Innovations Index is one of the world's most comprehensive databases of patents information. Over 11 million basic inventions and 20 million patents are covered from over 40 patent-issuing authorities dating back to 1963. Derwent provides access to the fulltext of most patents. Document Delivery may be available to access patents not available in full text.
esp@cenet is Europe's network of patent databases. esp@cenet provides access to the fulltext of the patents dating back to 1836. Using esp@cenet it is possible to search a worldwide database of published patents from over 80 countries and regions. esp@cenet can be accessed from the UQ Library Catalogue or is freely available on the Internet.
Scifinder contains information on patents and patent families in all areas of chemistry and chemical engineering from 50 patent issuing authorities. It is possible to search for patents using CAS registry numbers and chemical structures as well as keyword and inventor searches.
Google Patents provides access to US patents from the United States Patent and Trademark Office back to 1790. Full text searching is available for US patents after 1975 and for earlier patents - patent number and classification searching is available.
