After you write the patent application, you need to put it away for at least a day or two. Reread it after you haven’t worked on it for a while. When you get back to it, you will be fresh and be able to catch things that you missed.
Read and reread your patent application until you correct as many mistakes as you can.
To fix grammatical mistakes, use an online grammar checker.
Make sure that all of the terms are used consistently.
Make sure that all of the points written in the outline have been described in the patent application.
No perfect application exists. As such, don’t be a perfectionist. If you properly worked on the outline and described the various aspects noted in your outline, you should have the big picture in the patent application.
