They still could easily have gone with examining previous work to see what was attempted.
A recent example here: On a thread here recently, some people were trying to determine how to keep the spool synchronized with the extruder head so that the stepper on the extruder head did not need to have any load from the spool. Several people on here mentioned several previous similar ways of doing it related to tape feed. I really don't think that that would occur to a lot of the Maker movement. The whole fear of getting sued is a bit played out and does not really explain why they went to trying to design what amounts to CNC controllers from scratch. That whole process was pretty much out of patents prior to 3D even being patented. Sure.. FDM and extruder heads makes sense. Still patented when reprap started. But, motion control? Not even close.
