The Patent Classification System
Patents are organized by class and subclass of invention , similar to the way books are organized in a library). By using the classification system , you can find and examine patents that are in the same field (class) as your idea. The tutorial How to Conduct a Patent Search will introduce you to this form of searching, however, this is difficult material to master.How to Find Out if Your Invention Idea is Already Patented
If you have an idea for an invention, before you patent it you should check to see if it's already been invented by some other inventor in the past. Though actually, whether or not it's been invented, what you'll want to do is find out whether it's been patented before with the USPTO (the United States Patent and Trademark Office). Here you'll learn how to search patents to find out if your invention idea is already patented or if you should redirect your brainstorming to another invention idea. Have a question?

There is no EASY way. If your invention is a new can opener, an existing patent for the same idea may never use the words can opener. For example, it may be described in broader terms: container de-sealer or metal wall scissor. The patent offices classification system helps a bit, but not much. Inventors tend not to want to find their invention, so, they type in --can opener-- and look at a few and say they couldn't find it. You have to look for it like you want to find it. try different search terms. when you find one thats close, look at the references cited in that application and look for other patents wherein the close one was cited.How to Patent Your Idea
Contrary to popular belief, you can't get a patent for something that's still in idea form; you must be able to apply your idea in a concrete way. This doesn't mean that you have to build a prototype of your invention before you can get a patent. However, you have to be able to draw or describe it in enough detail so that someone else could make it and use it. Have a question? Get an answer from a lawyer now!You Can't Be Too Obvious
Even if you don't find the prior art to prove it - you will not get a patent if your invention is not different enough from similiar inventions that are already out there. A patent maybe refused if the differences between your invention and another invention are too obvious. Your invention must be sufficiently different from what has been used or described before that it may be said to be nonobvious to a person having ordinary skill in the area of technology related to your invention . For example, the substitution of one material for another, or changes in size, are ordinarily not patentable. You can't paint it red and make it twice as big and expect a patent. Another example of "nonobvious to a person having ordinary skill in the area of technology related to your invention" could be the following. An electronics engineer looks at a circuit board and observes that it is just like another circuit board except that a few parts are substituted. Someone who is not familiar with circuit boards may not understand that the two boards are very similar, however, someone with training thinks that it is obvious. You would want the electronics engineer to look at the circuit board that you want to patent and say, "heah, why didn't I think of that!"
