Thanks for the links, they are useful
I don't know if any aspect of the Thinklight concept or its implementation is patented or covered by design rights, etc. I would hope not - it's just a light with a switch! - but "Method of swinging on a swing", and all that...
Looks like HP & DELL also have that feature, so hopefully it is not patented.
In fact I've never used a backlit keyboard so I cannot compare the 2 solutions, but the LED was very effective for such a simple thing.
