PCB/SoC component licensing restrictions
Purchase of components implies either explicitly (through language in the datasheets) or implicitly a license.  Put another way, if someone sells you a component that allows you to do something, and then they sue you, they can easily be counter sued for entrapment.  The real concern is if you are using a component that infringes on someone's else's patents or IP's.  Then you need to discuss indemnification with them.  It would be silly for a manufacturer to go after you for using their own components.
