Negative.There is a lot that is bothering me about what has been described.
It sounds to me like the subpoena on the third party for information on the Utah party is a fishing expedition, trying to find out information on the defendant that falls outside the underlying breach of contract suit.
At any rate, a forum is unlikely to be able to solve the problem of service of the subpoena.
The subpoena is information we are directly allowed under the law but defendant refuses to provide.
Why would you say its a fishing expedition ?
The California company is not google if that what you are thinking but they do have a monopoly over their industry which is why they have a lot of business in every state including Utah.
