I am in a an agreement with a very major corp. that is not fulfilling their end of the agreement. Can I sue for full value?

You need to have your contract reviewed by a qualfied patent/business lawyer, perhaps by the lawyer that negotiated this contract for you in the first place, to determine the scope of your rights. Your contract may have required the corporation to bring the product to market within a prescribed time and to give you input, or not, and there may be other terms that were breached.

Your rights for damages for breach of this contract, to be paid the "minimum amount," or possibly to rescind (cancel) the contract for lack of consideration or on some other theory to get your patent rights back, are all dependent on the contract. Likewise, your dispute resolution options - do you have to give them 30 days to cure? do you have to arbitrate? -- will be determined by the contract itself.

This answer does not create an attorney-client relationship.

Possibly, but calculating your damages is probably more complicated than just what the company is supposed to pay you. It is not necessarily what they pay you, but the profits derived from the contract. The terms of the agreement itself might also determine the damages amounts.
