I've been developing a solution engine for a particular vertical market since the days of FM2. Some four years ago I created a run time derivative from that engine under contract with a client. The contract stated specifically that the deliverable to my client was the run time only.
My client now wants to sell their business including my run time to a buyer. The buyer, supposedly expert in these matters, believes my original client was entitled to the full engine from which the run time was derived. Which means that the buyer of my client's business would be taking ownership of my full solution engine when their purchase of the company has been completed. Of course, I disagree and would only part with the full solution engine over my dead body.
Does anyone have an opinion or precedent to cite which could clarify this matter?
