Did you ever licence it or say they could only use it for a limited time/use?
So there was no licence agreement signed?
Its bad news I am afraid to say. If there was no licence agreement signed and you have brought it to the table, you sadly can not now stop them using it
This is because unless a contract was signed and you let them use it, it would be very difficult to now claim they had no right to to do
The proper way of doing it would have not let them use it unless there was a licence in place.
I am sorry if this is not the answer you want and certainly not the one I want to give you, but I have a duty to be honest
Can I clarify anything for you about this today please?
Can they demand the documents etc - no
They can use it, but they can't demand the design, manuals etc.
These all belong to you
Does that clarify?
That is correct.
Does that help?
The site is not designed for legal research as that can take many hours. But there is a free legal database you can search:
There are Practioner ones but they are subscription based.
Does that clarify for you?
