 You don't know what you don't know. You have to do a search. One of the skills that I learned at the patent office, which is vital if you're looking to try and get a patent is learning how to search. I think the expression at the patent office, the reason you do a search is because you don't know what you don't know. You don't know. You have to do a search. Once you see what's there, like in my fingers, let's say these are ideas. What you wanna do is you wanna look at the disclosure and you try and see which one of these fingers, which one of these patents, okay, reflects your idea. You wanna make sure your idea is not like theirs because if it is, it's an automatic rejection. So what you try and do is you try and get your idea in between the cracks.
