Apparently it can make it round the corners OK at light weights but when any reasonable load is carried it puts unacceptable loads on the u/c and scrubs the tyres to bits, so I have been told.
As far as patents go can't comment but if I had been Boeing I would have made some improvements to the system along the way, especially when the -400F came out, and re-patented it.
I am sure I saw photographs, somewhere on the internet, purporting to be a 380 u/c with the tyres scrubbed off the rims - taxying not landing was the claim.
