Re: Patents are supposed to limited usage of IP to the inventor
These are standards essential patents, as sunch they must be licenced under FRAND (Fair, Reasonable and Non-Descriminatory) terms.
Qualcomm got together with other industry tech companies to create a set of standards within (in this case) mobile phone chipsets. Had Qualcomm not wished to be a part of the standard there was no legal requirement for them to do so. By getting their patented technology into the agreed standard they massively increase use of their technology. The cost of this is that they must licence their technology to users of the standard under FRAND principles.
Let's say you design a new safety mechanism for usb chargers that makes them impossible to explode. You could either produce your own chargers and sell them on the open market, licence your invention to a company or two to include in their chargers or you can come to an agreement with the standards body (BS, ISO etc) to make it an integral part of the design for all USB chargers. If you were making your own chargers you'd have a unique selling point that you could possibly tack on £2 onto the price of the charger. If you licenced the product to a company (that had bigger market presence) you might see 50p on every charger sold, however they'd sell way more than 4x the volume of you selling just your own chargers. The final option may only offer you a return of 10p per charger, but if every one sold in the country must contain your technology that adds up fast.
What Qualcomm are doing is the equivalent of you agreeing for your technology to become part of the standard, then once the standard is agreed demanding 50p per charger for the tech.
The non-discriminatory part of FRAND also comes into play. Suppose your arch rival in one of your other businesses (selling kettles for example) decides to get into the USB charger market. To do so they need to get the licence off you to allow them to include your design (which is required by the standard). You think "Ha! I don't like you very much. You can't have a licence" or "I'll charge you £2 per unit for the licence". Neither of these options is allowable under FRAND.
