Moog did uncover the offending module in their factory and sent a patent
infringement nastygram to ARP.  The parties were about to work on licensing
to settle the matter when ARP noticed that Moog was infringing on their
linear to expo converter patent in their synths.  Both parties wound up
with guns pointed to each others' heads before they said 'oh forget it'.
No legal action was ever pursued, although ARP did discontinue any filter
modules that infringed on Moog's patent which was how the 4072 and 4075 VCF
modules became reality.
