Gosselin is expected to appear Thursday when a judge hears arguments in the case.
The network wants the judge to stop Gosselin from making media appearances that it says violate his exclusive contract. TLC, which is owned by Silver Spring, Md.-based Discovery Communications, says the contract remains in force.
Gosselin claims in a counterlawsuit that TLC violated Pennsylvania's child labor laws in filming his eight children.
His attorney, Mark Heller, says there is no reason for the network to stop him from earning a living as a media personality, especially now that the show has ended amid the Gosselins' pending divorce.
