But I don't know anything about patents. |
Well, neither do I but, just from the abstracts, no one is allowed to make an optical disc player ever again except LG.
The drawings and dense techical specification may well contradict that impression.
In one specific area I do know something about; CPU and GPU design, the patents are set up so that no one outside of the companies who already do can make a modern graphics chip or processor without having to license from Intel/AMD/Nvidia/IBM and a few others. Not even if they do it in a clean room style.
Those companies have to cross-license with each other regularly or else it would be a cold war of patent annihilation.
