As I understand it, Lodsys, the patent holder is suing the 3rd party developers for using Lodsys' patented technology within the developers apps and to be clear, it's usage for one developer (if not all the developers) is in the in-app upgrade button.
So, if they "win" this lawsuit, wouldn't Lodsys then be able to sue every consumer that clicks on that upgrade button for using that patented technology without first setting up a licensing agreement with Lodsys? No? Ahh yes, the developer is incorporating the patented technology into their product to sell to the end-user. Ok so that's clear...
But,
If Lodsys wins this lawsuit, wouldn't that mean a company such as Intel, could now sue every PC builder/modder who resells these custom built PCs for not contacting Intel first and establish a license for using any motherboard that uses any Intel chipset that comes soldered onto the motherboard by the motherboard manufacturer not including the CPU? It's assumed that you paid for the CPU chip directly and therefore any licensing fee is included that purchase.
For example, any USB equipped motherboard whether it's made by Asus, Acer, Gigabyte, Dell(?), HP(?), Apple(Foxconn?) and so on, that's used to build a PC and then resold, the builder of these PCs is supposed to, according to Lodsys, contact the patent owner (license owner) of USB (Intel originally and the USB org now) and set up and pay for a separate license, even though the USB technology has been incorporated into a larger piece of technology (the motherboard) and the license paid for by the motherboard manufacturer.
Is it really the problem of the 3rd party developer that Intel or the USB org didn't negotiate a better deal with the motherboard manufacturers?
And yes, my "doomsday" threat is that any individual who builds a custom computer for someone else and gets paid something to do so, the onus is on the builder to contact all the patent holders who have a patented technology that's used in building a motherboard or a hard drive or even a memory card and work out a license agreement or face litigation by any of these patent holders. Anyone know who owns the patent for PCIe, Sata, 1000baseT, solder, 1/8" plug, digital audio, ASCII, or motherboard spacer screws? Anyone know which of these previous items are not applicable to the scenario that Lodsys is claiming? Only people who build motherboards know.
I don't pretend to know what the law states in this matter, but it seems to me that the onus is on the patent holders and the motherboard manufacturers to work out their licensing agreements and NOT the patent holders and the "developers" using these motherboards.
