NEC TSC: Intellectual property rights

Under the NEC3 TSC what are the rules around intellectual property rights? Can the Client use information provided at the Contractors expense under the pricing of a Task Order to then go out and use under an open market tender?

This situation is not covered by the contract so contract law in terms of IP would apply. I stress I am not in any way an expert on this just vaguely knowledgeable.

The first thing I would query was whether it was genuine IP or just ‘know-how’ which often gets confused. For it to be genuine IP, it would need, at a minimum to be copyrighted.

Having said all of this, it does seem a bit unethical.
