Why didn't Vitale get rich?

She waited to patent her pizza table, and someone else invented one.
She inspired other pizza tables that were more successful.
She didn't manufacture the pizza tables, and the patent ran out.
She didn't have proof to show that she invented the pizza table.

It is likely that Vitale did not get rich because she did not patent her pizza table in a timely manner, allowing someone else to invent a similar product and profit from it. Additionally, not manufacturing the tables and having the patent run out could have also contributed to her lack of financial success. Lastly, not having proof of her invention may have hindered her ability to defend her claim to the invention and profit from it.
