Online help is provided. When looking at the full Patent, we want to look at the drawings and read the claims. If you find that the invention has already been patented, you may not file for a patent on it. If you do not find a patent that is the same as your invention, you can proceed to prepare a patent application. Remember you will also need to search the Classification Information to look at patents issued before 1969.
