I am hoping to clear something up. I understand that it is not recommended to try to patent a formula since most cosmetics and personal care products are not unique and formulas can easily be recreated. However, I have been told that a patented formula protects you from being sued later on (if your product becomes successful) by someone claiming that you are using their formula. Is this true? I am happy not to try to patent my formula to save money for marketing however this claim makes me nervous.
