Stories like this always remind me of Dyson's battle with Amway who thought they could just steal his idea. He put everything on the line, his house, business, everything and he won. He started off as an Engineer but now he's a Billionaire.
BA tried to destroy the then fledgling Virgin Airlines so Branson sold his beloved Virgin Records and told the wife the house was on the market. He took them to court and won a million in damages. He's a Billionaire now by the way. Probably not very helpful unless you want to risk your house to prove you're in the right.
