You'd want to be sure that you have created something unique and it is not
already in production.

The best way to protect your IP is through copyright notices - just like any
written work, this could be your best protection. Probably best to get some
legal advice, perhaps from a community law practice, which is usually free.

I am interested to know if it is legal to sell an Excel spreadsheet that I
have created. If it is legal a couple of further questions

- what type of disclaimer do Microsoft require you to include with the
spreadsheet if any and where would I find that

- does anyone know how you would use Excel to prevent the copying of the
spreadsheet once sold ? Is there some way of registering and recoginising a
particular installation of Excel on a machine that would mean the spreadsheet
could not easily be passed between people
