The United States Patent and Trademark Office (USPTO) Web Patent Databases

now includes every United States patent ever issued, a total of more than 6.5 million patents, says a USPTO news release. Two Databases are availible, a Full-Text Database and a Bibliographic Database with boolean search functions. "Effective 1 October 2000, the Full-Text Database now offers all US patents issued since 1790, in the form of searchable patent numbers and current US classifications hyperlinked to full-page images of each page of each patent."

The European Network of Patent Databases:

espace was created to "increase the general awareness of the wealth of information contained in patent documents, Switzerland and other members of the European Patent Organisation have set up a patent database known as esp@cenet. Using this database, anybody can gain a first impression of the kind of knowledge contained in patent certificates. But a word of warning: Esp@cenet was designed as an information awareness programme and is not the same as a professional patent search."
