FBR General Discussion, page-1718

To be politically correct FBR and WB both have strong positions. But in reality, FBR has a much stronger position. The green machine by KM Robotics is about where it can only go, it is stuck. FBR has everything tied up with their IP. Read through the patents if you have time, Mark has absolutely covered everything. WB with only the green machine to turn to will have another 100 years to work out a way to install their oversized bricks and blocks. In WB's own words, these large size blocks can only be installed mechanically. So, WB can only turn to FBR whereas FBR has the rest of the world. This may be oversimplifying things, but it is true.
