I should back up a moment and state that I think we are all talking about commercially available patterns. As already pointed out, licensing is a different matter. In that case someone agrees to a contract with you whereby they will allow you to make copies of their original design in exchange for a fee but the design/pattern is not commercially available. In that case, the creator of the design/pattern can state what rights they want to retain, and what fees they will charge, and you have the option of entering into the agreement or not.
