How do I find patents?

Patent Searching

United States Patent and Trademark Office (USPTO)
The USPTO offers web access to bibliographic and full-text patent databases. These databases provide full-text of patents from 1976 to the present and full page images from 1790 to the present.

See Patent Searching Tips.

Fresh Patents
Provides access to the latest published US patent applications each week BEFORE the USPTO decision to
grant/deny.

pat2pdf.org
Given a patent number, pat2pdf.org will return a free, pdf formated version of the patent.
