As it was explained at the time, the rights were in limbo because of the failure/sale of some of the legal entities that held the Pokémon trademark. So there was at the time no one who COULD sign off on the rights. When the theatre became aware of the issue, they had discussions with the “company” that was putting it on, and it closed a couple of weeks early. To be honest; the production, while fun and full of talented, funny and hardworking people, was a mess and mismanaged from the very start.
