“Dreams don’t work unless you do.” – John C Maxwell
How truly and appropriately said! The would-be inventors also think along the same lines when they plan to conduct patentability search for their inventions. At times due to budget constraints, the would-be inventors decide on conducting the patentability search themselves. While this may sound quite lucrative and exciting, it may prove quite daunting and discouraging if one does not have to the point knowledge about the specific tools available online to conduct patentability search.
Google patents is one of the free patent search tools. Google patents was launched in 2006 as a search engine.
