Many inventors often hesitate entering into the expensive invention
market because they are worried that their product is already out on the
market or that there may be obstacles that they will run into. With a
little effort on your part, you can investigate on a preliminary basis
whether or not your product will succeed, and while it is not a one
night project you should be able to complete the project in 30 days. I
think every inventor should do this to ascertain whether or not the
product has a chance at success before spending a lot of money.

Patents has a feature called prior art searching. Typically, patents
are granted only if the invention is new and not obvious, which means in
patent language, that there isn't prior art, which simply means the
product hasn't been publicly disclosed previously either in a patent, by
being sold, or in some other fashion. The Prior Art Finder makes it
easy to search multiple sources simultaneously for prior art. You can
experiment with it by clicking on the "Find Prior Art" button from a
patent's main page, or on the "Related" link in patent search results.
The
Prior Art Finder identifies key phrases from EPO (European Patent
Office) and post-1976 US patent documents, combines them into a search
query, and displays the results from Google Patents, Google Scholar,
Google Books, and the rest of the web.
