 And there's no law that requires a patent attorney to conduct the search. However, most inventors, when they do their search, they're focusing on using keywords. And keywords are not accurate. But one person calls a hose, somebody else will call a pipe, and you might miss the closest known patents. Additionally, there are marketing companies out there that track search terms online, and you may inadvertently give away your idea. But when a patent attorney conducts a search, we'd go by classifications at the patent office, find the closest classifications to your idea, and go through and find the closest references. And that's the right way to have a search done.
