I know how patents are written. The point is you cannot legally in court protect something that is not well defined. You cannot prove that I am infringing your patent, if your patent is merely an idea with no implementation. If you invented a 3D touch screen, you can patent that invention using claims that descibe the implementation, you cannot patent the idea of a 3D touch screen with no implementation. The very essence of inventing something is to create something that solves the problem of making an idea *work in real life*. If somebody else created another 3D screen using a different implementation, there is nothing you can do about it because it is a different invention. But if someone used your implementation creating a 3D television, they are infringing your patent even though it is a different idea.

Another point is that even tough you have invented something completely by your own head, if it has been done before, you are infringing.
