In 2013 the trainer returns to the club, but when he later switches to competitor Manchester in 2016, the question arises: who owns the trademark rights to the name? What is mentioned in the contract about this? During the transfer it was rumored that these trademark rights formed an obstacle. When Mourinho later switches to archrival Tottenham Hotspur in November 2019, the question arises whether his name can be used freely for all intended merchandising?
The rights are still held by Chelsea, but the club does not renew the registration in time. This may be the result of a settlement between the parties. A lesson for the future. Register the trademarks on your own IP entity and license it out to yourself.
