they still own the rights to it
saying it's a standard and open dosn't make it so

Physx is an open software standard any company can freely develop hardware or software that supports it.

Can someone explain that statement to me? Can't ATI hardware support PhysX? I don't understand that statement at all, sounds like marketing bull and double speak to me.
