Funny how some people argue that Texas courts are all fair and just like all the other courts about patents... But, those types of things keep get being filed there repeatedly... Which kind of demonstrates the lawyers themselves don't think so.
Lawyers obviously prefer to file where they think have the best chances.
- Apple, for example, loves to file in Northern California, near their home base.
- Many companies file in East Texas because those courts are reputed to lean towards patent holders, not the infringers.
- The first time that Nokia sued Apple over non-payments, they filed in Delaware, asking for a jury trial. Delaware is the second-most friendly state towards patent holders after Texas. It's also well known for being able to handle very complicated patent cases.
I don't understand why Apple would need to pay any licensing fee they don't manufacture the chips? Shouldn't it be the manufacturer of the wireless chip that needs to pay the fee.
No, because the chip maker doesn't control what manufacturers do with their chips.
Think of it this way: anyone can buy CPU chips at a set price. However, if you plan to use those chips to build an MP3 player, you'd better plan to also pay royalties to someone. The maker of the CPU chip is not responsible for what you do with that chip.
For example, let's say that for a remote data transmitter, you buy the latest radio chip that is capable of GSM, GSM/HSDPA, CDMA, LTE, WiFi, Bluetooth, etc. However, you only plan to use GSM 2G. Why would you want to pay a hefty built-in fee for all the other standards? You don't. You only want to pay for what you need.
Even Qualcomm charges separately for their own patents. Every company ... even Apple ... pays two prices to Qualcomm. First, there's the base price of the chip itself. Secondly, there's an IP royalty that's calculated by what the price of your device will be.
E.g. Apple pays Qualcomm $15 per chip, PLUS another 3% of the "price" of the iPhone... which Apple has cleverly negotiated to be the low ~$240 price they pay Foxconn, not what they later charge the consumer.
