A wise man once said...
“You do not really understand something unless you can explain it to your grandmother.”
— Albert Einstein
My own Grandma should understand it!
Through our illustrations, we make it easy to see what the intended invention is used for and how it is used.
In a Utility Application, we sometimes prefer to show in the first figure an Environmental View to illustrate how the item is used. Then we show different views of the item to help understand the key aspects of the device. With each figure, the details become more clear as to how it's assembled, what parts are used, and the materials of the components. Through the illustrations, we are providing visual information how the device moves, turns, opens and functions. These are all key elements a patent attorney use to describe the figures in their written portion of the patent application that will be submitted to the U.S.P.T.O. A good draftsman develops the figures in a sequence of greater detail that makes it easier for the attorney to follow and describe. This is essential, because it allows the U.S. patent examiner to understand the invention with ease.
Thus, making it simple enough that your own Grandma could look at, and understand it!
