So if Apple is infringing because they used AMD hardware, aren't everyone who owns a machine with AMD hardware also infringing?
While the whole patent system is tending toward absurdity, it's really absurd that you can be sued for infringement by using a product that infringes even if you have no idea or even a way of knowing that...
It might be the reason that Apple are infringing on the patent is that they are selling, not just using, a product which contains something which infringes the patent.
Using something with unlicensed patented technology exposes you to liability as well. Otherwise you could just make shell companies to add the final software piece to a product and cleanse the liability from all the other players.
