Very interesting, thank you. Could you talk about what the liability is if you buy from someone who is (unbeknownst to you) infringing, and what your responsibility is if the seller turned out not to have a license?
What if the component you bought has already made it into your products?
The rule is that you can be liable if you make, use, sell, or import the infringing device. In theory, end users are also liable. Individuals as end users usually are accused - no upside. Businesses as end users sometimes get sued.
