The U.S. Patents and Trademarks Office has a fully searchable, free database with text and images of over 2 million patents and 1 million registered and pending trademarks. A useful tool to verify the availability of a new product name, though not exhaustive, since many trademarks out there, with proof of first use, never make it to the Trademark Office.
