Resources by format

Here are listed guides for finding materials based on their formats.

This list of resources will enable you to retrieve most U.S. patents or trademarks, if you have a specific citation. However, if you have a product idea and want to determine if a similar item has been patented, searching these resources to determine patentability may be difficult. Patent and trademark searching can be very complex, and unless one has experience the results may not be valid.
