My boss has developed a training course for the undisclosed Company. The undisclosed Company has approached my boss for the training course and when proposed, they asked to change it to train-the trainer course for undisclosed number of course runs. After conducted a few course runs, the undisclosed Company calls for a pause in lesson plan. The undisclosed Company used my boss to teach their trainers and can their trainers continue to teach the rest of their staff.

What should be do,
1) Can we claim for intellectual property rights?
2) Should we not give them a copy of the powerpoint slides and course notes
3) Should starting licensing and only certified trainers can get to train the others, come up with refreshing course and practicing fees?
4) State that it is unfair and insisted that they should continue with the lesson plan, if not, asked for a compensation for the business loss, because my boss has reserved the dates for teaching and had postpone other appointments.
The problem is, we have not patented or license the course materials yet, but my boss is the originator of these information properties.
