Following a simpler definition, royalties are payments made by one party, the licensee (the user of intangibles), to another party, the licensor (the owner of intangibles), for the use of intangibles owned by the licensor. Royalties are often expressed as a percentage of the revenues obtained using the owner’s property; however, they can be also expressed in other terms (including a fixed value), depending on the specific characteristics of the licence agreement.
