I'm not sure if patent exhaustion applies since QTL (licensing) and QTC (chip-making) are technically two separate business entities (subsidiaries). I wasn't aware of that; that's quite interesting. But it's unclear whether it affects exhaustion, in that QTL would still have (or have not) licensed Intel (or QTC). So either (Intel or QTC) have a license and exhaustion applies, or they do not, and are the actual infringers. Now, the law being the law, "the actual infringers" is not going to be a strict legal concept, but in some areas of law and/or some jurisdictions, there are legal structures that produce similar outcomes – where a suit cannot be brought against someone one or more "jumps" away, e.g. just to find a defendant with deeper pockets. I'm absolutely out of my depth re: US patent law on this topic, except that it seems insane for a patent holder to be able to sue all the users of an infringing product. But then patent law so ¯\_(ツ)_/¯

Ok. it's actually fairly simple. A minor correction though: Qualcomm actually never made their legal argument based on QTL and QTC. Qualcomm did argue that their patent portfolio goes beyond baseband chips and their customers are paying for non-chip related features that cover security, encryption, algorithm, etc.. (hence no exhaustion) And yes, it's perfectly legal to pick anyone one, not all, layer in the supplier chain and collect royalties there. The wireless industry agreed to collect the royalties from the last manufacturer in the supply chain decades ago -- and that's more or less the de facto industry practice today. This isn't to say SEP holders can go after any random body as they please -- there are legal analysis and factors that help determine if that's fair. For instance, I think it's reasonable to use the end-user smartphone device as royalty basis since Qualcomm's IP adds significant value and drive market demand for Apple's iPhones. On the other hand, it would be silly to make similar comparison to a BWM 8 Series Coupe with wireless functionality.
