When one is dealing with the process of applying for a patent, one must of a necessity have all of their documentation, as well as papers and other items in good order, so that when it comes time to go to the patent office, all issues will be addressed. The getting and receiving of patents on things that you have invented, is like all other processes, one that requires that you do your home work, and that you have all of the evidence that you are the first person to ever come up with the creation in the beginning. That way you alone will own the rights.
