If you are actually sued for patent infringement, then it means you've got deep pockets to pay a judgment or settlement. In other words, you're probably making a ton of money. It's a good position to be in.
That’s…not true. Anyone can sue anyone for anything.
Patent trolls often go after individuals and small firms specifically because they can get them to settle as they cannot afford a legal fight. Most make the bulk of their money by without ever getting any judgements.
