First, determine whether the authorization obtained is an exclusive license, an exclusive license, or a general license.

Exclusive license: Within the specified geographical scope, the licensee enjoys the exclusive right to use the registered trademark authorized for use. The licensor may not license the same trademark to a third party, nor may the licensor itself use the trademark in the region.

Exclusive license: In addition to the licensor giving the licensee the right to use its registered trademark, the licensee may also enjoy the right to exclude third parties from using it.

General license: The licensor allows the licensee to use the registered trademark under the contract within the specified geographical scope. At the same time, the licensor reserves the right to use the registered trademark within the region and to grant third parties the right to use the registered trademark.

At the same time, it is also necessary to pay attention to whether the trademark owner has changed, transferred, been opposed, disputed, and whether the trademark rights have been renewed in a timely manner and other legal processes.
