There are several things to consider here.

1. Most of the time lawsuits are a threat not because of cost of losing the suit but the cost of achieving the victory. Someone that can spend $10,000 at the drop of a hat, can force you to spend similarly. It doesn't matter whether they win or lose, they still hurt you.

2. Sometimes a small target is destroyed to set an example to larger targets so they can be threatened more effectively.

3. (removed by Max for review)

4. Finally, the way it sometimes works is that your opponent gets a cease and desist order against you from the court. Then if you ignore it, you don't get sued for money, you get be arrested for contempt of court.

Sorry if this seems grim, but its just a bit of a warning. Its easy to believe that the threat is minimal, and it might be. Still, I'd make sure it was.
