The trademark registrant is basically the trademark owner. The right to use a trademark belongs to the owner. When others want to use it, they must obtain the owner's authorization. The profits will be stated when authorizing, and the rights and obligations in the authorization letter will be followed. Generally, it is clearly stated the time limit of use, the usage fee (it can also be the amount of one-time payment, or it can be charged based on how many goods the trademark is used on) the user, the goods that the trademark can be used on, whether it can be sublicensed, etc.
