Good question dtaylor :)
good one but easily answered:
It would still have to be distilled/matured in Scotland to be called Scotch whisky though.
exaclty, even if the 'Scottish' Company was taken over by a 'Polish' company, for it to be Scottish whisky, it would still have to be made to the original patented specification. Misty is also correct as to be 'Scottish' whisky it would have to be distilled and matured in Scotland.
When you are buying a company or other business, you are not buying business really, you are buying their products, ideas, designs etc etc and this all comes in the way of patents and copyright protection. In other words you are buying 'assets' to add to your own company
