I just disagree with the Graphene thing.
It looks like a Red Herring to me.

The 99% graphene stroy is just a speculation, not based on reality.
The researchers found some traces that might be graphene, but they were not certain.
The patent does not mean that they are using it now, they have other tech already.
Graphene is mainly used now for filters, So if it is found at all, it may be from the filters.
