PubWEST is a collection of patent databases available for free only at the U.S. Patent and Trademark Office (USPTO) in Alexandria, Virginia and at Patent and Trademark Depository Libraries. Find out how searching U. S. patents in PubWEST is more flexible and efficient than searching in the USPTO Web site. Also learn about keyword searching in older U. S. patents (1920-1975) and in the English language abstracts of European and Japanese patent documents. In addition, many foreign patents can be searched by patent number.
