With Google Patent Search, you can now search the full text of the U.S. patent corpus and find patents that interest you.

Google Patents is a search engine from Google that indexes patents from the United States Patent and Trademark Office (USPTO), which are taken from the original USPTO database (which is in the public domain). All 7 million patents have been put in the database. Optical character recognition (OCR) has been performed on the pages to make them searchable. This searchability includes all US patents.
