The license agreement should clearly identify the property or properties to be licensed (e.g. character, design, trademark, etc.), and, if applicable, copies of the licensed property should be attached as exhibits to the agreement. The licensee should determine that the property is protectible under copyright, trademark or other applicable laws, and may want registration numbers to be listed in the agreement. If the licensed property is a trademark, the licensee may also want to require that the mark be registered for use on the types of merchandise to be produced under the license agreement.
