When you can say you have a Patent Pending on a new product you are starting to market it gives you a little peace of mind. Everyone know that when the patent process is complete you will be able to go after all the profits of anyone that has attempted to profit from your idea all the way back to the date you filed for the patent. Most rip off artists know better than to try to copy a Patent Pending product because they will most likely lose and profit they make from the inventor that went to the expense to apply for the patent in the first place.
