What is the difference between a PROVISIONAL and a UTILITY patent?
A provisional patent is temporary to protect your idea as soon as you get it, then you will apply for the utility patent asap, which lasts much longer.
What is the difference between a saw horse and a mule?
I don't know what a saw mule is, but a saw horse is a free standing set of legs to make a makeshift table out of two and a flat/board (or use as a barrier in a corn maze). A mule is a donkey/horse hybrid animal.
