What do you call info that u have generated on your computer?- I thought it was "intellectual property"

Question

Talking about designs, drawings, photos that I have done - client wants this all returned so that he can give them to someone else - have given him soft copy of all I have but beleive I do not have to give anything that has been generated by me and stored on hard drive in computer. I have not yet been payed for work carried out.

Answer 1

You speak of the client wanting things 'returned' - this presumes that the client gave it to you in the first place?

If you have genuinely created something original, or at least provided specialist work in the context of a commercial transaction then the client must pay for it before using it, something that should be spelled out in a written commercial arrangement prior to starting the work.

Answer 2

Please go and register patent for the programme, design,etc you have done, it's a way to protect yourself. If someone have used your design, then he had to pay you for the copy rights.

Answer 3

Though not an expert in this subject matter I can at least offer you the following site entitled, "what is intellectual property?".  

The description does appear (on the surface) to match the type of material you reference, but I think it would take more research on your part to be certain about whether the term and all the legal protections apply to your particular work product.
