Let’s say you do want to make the invention and sell it. You will have to make sure you file the patent properly. That’s to protect your idea and so one else can copy it before you can get it to market or soon thereafter. If you do, then you may risk losing out on potential profit. A good patent attorney will be able to file the necessary papers for you to make sure you obtain your patent. See, if you file improperly, you could delay getting your patent, and you have fierce competition, you do not want them getting the patent over you just because you forgot to file one or two papers. When you have a patent attorney, you can sleep well at night knowing they have you covered.
