I think that contains some information that bears on your situation.
My short form advice to you would be: don't worry about lawsuits that you have not been confronted with. It's fine to look ahead but this is something that most likely will never come to pass and you have no control over whether and when it will. Such lawsuits are typically reserved for companies that are wealthy enough to defend against them, a proverb in my country says that 'you can't pluck feathers from a frog' so if you're not a very plump target with assets in the US then you have little to worry about.
Concentrate on your product quality, market it with realistic expectations and you'll likely be just fine.
