A Master License is a legal agreement that allows a licensee to operate under a brand or trademark, granting them the authority to sub-license the rights to others. This type of license is commonly used in industries like franchising and software, where the master licensee can expand the brand's reach by allowing other businesses to use the brand's name and products. Typically, the master licensee pays an initial fee and ongoing royalties to the original brand owner, known as the licensor. This arrangement benefits both parties, as the licensor gains broader market presence while the master licensee can generate income by managing sub-licensees.
