Basic and Advanced tool for searching U.S. patents and applications.

Google Patent Search covers the entire collection of issued patents and millions of patent applications made available by the United States Patent and Trademark Office from patents issued in the 1790s through those most recently issued in recent months. International patents not included.

Simple searches on bibliographic data in patent documents. The default printing option is page by page only - but they are free. To print an entire patent, follow these instructions: Search for a patent. Click on a title; when the page loads, click on the original document tab. When this page displays, the printer icon is grayed out. Click on Save Full Document at the top of the page. Read the screen and enter the letters shown. The entire document loads now as a pdf and all the pages can be printed.

From the USPTO: If you’re new to the process of protecting your rights to your invention by applying for a patent, you’re in the right place. This page will direct you to everything you need to know about U.S. and international patents.
