Enrico, please note my original comment: "I'm sure there is a slight change to the instantaneous pivot point which gave them a thin defense." That is to say, that Giant's link is just different enough that the outcome of a patent infringement case would be difficult to predict. What you seem to not understand is that the location of one pivot doesn't necessarily affect the characteristics of the motion (note that every single DW link is totally different - see Turners new DHR vs the old IH Sunday); it is the location of where the instantaneous pivot point is throughout the stroke of the suspension. If you draw a line through the two pivots of the upper link, and then the two pivots of the lower link, they intersect at this IPP. That is where the wheel pivots around at that point of the stroke. While the exact geometry is different for Maestro, the concept and tunability of the design is the same. Arguing with you is like trying to talk to a dog.
