Google Patent Search covers the entire collection of patents made available by the USPTO—from patents issued in the 1790s through those issued in the middle of 2006. We don’t currently include patent applications, international patents, or U.S. patents issued over the last few months
The new search tool makes a joke trivial - have you ever tried to check if your idea is original? Try it now, and be amazed at how many people out there get patents, and for what silly “inventions”.
