The United States Patent and Trademark Office provides a wealth of information about patents, from Guide to Inventors pamphlets providing basic explanations of the various types of intellectual property to a Patent Searching database.   This database is available free of charge, for conducting full text searching of issued U.S. patents since 1976 and patent publications since 2001.  Assignment record searching, to search patents by owner, is also available.


For patent protection in foreign countries, many applicants utilize the Patent Cooperation Treaty (PCT) procedure to defer costs.  Information about the PCT, such as a basic facts guide, can be found at the website of the World Intellectual Property Organization (WIPO).


EPOThe European Patent Office also provides a free search engine, which contains not only European Patents, but also full text searching of PCT (WIPO) publications.
