[citation][nom]kronos_cornelius[/nom]Intel has a piece of paper called a patent. Nvidia has a chip being manufactured at thousands per day. I would say Nvidia has more than enough evidence to show prior art. The Tegra 3 did not just come into existence in the last 4 years. These things take time. This just shows Nvidia puts more resources into engineering where Intel puts more resources on lawyers.[/citation]
Intel can have whatever patents that they want. Having a patent (even a stupid one) doesn't matter. Now, if Intel attacks Nvidia through this patent, then I will see problems. However, Intel might have patented this before Nvidia tried it out. Nvidia should have patented it or at least done something about it themselves, but they didn't.
This does not show that Nvidia puts more money into work and Intel puts more money into lawyers at all. In fact, if Intel does not abuse this patent (they might, they might not), then it is a good thing that they patented it because it will stop someone who would abuse it from patenting it and suing everyone. Lately, Intel does not seem to be the kind to sue another company right now, so they probably won't do it. However, this patent's similarity to Tegra 3 is alarming, so it is possible.
Besides all of that, from the looks of it, this seems to only apply to X86 CPUs, so it's no big deal if Nvidia keeps Tegra as an ARM based CPU.
