Coming from guitar land myself (I’ve been playing guitar for 25 years, but am only recently a synth player/buyer), pedals/guitars are a place where copying designs is nothing new. Think about how many mid-size pedal companies who have revolutionized the effects industry also at one time sold (or still do) an outright TS-9 rip. Sometimes the circuit gets improved. Sometimes it doesn’t. But it’s a great point that Keeley, JHS or Wampler (or whoever, I love those guys and am not using their name except that I pulled it out of a hat) didn’t then go and sue Ibanez. Probably because they are decent human beings. In fact I know this to be the case.
Or take the revered Klon Centaur. It’s a three knob overdrive that is out of production and sells for about $4000 on Reverb. That’s dumb. Hence the numerous Klon clones. This equates directly to the Minimoog/Model D thing.
As far as instruments in production today.I mentioned the strat/tele earlier. Find me a more prolifically stolen musical IP anywhere. And yet, I doubt that anyone who can afford an American Elite Telecaster and who understands the difference is going to buy an Indonesian knockoff. They’re two different market segments. I owned and cut my teeth on a ton of shitty electric guitars until, one day, I could tell the difference. That day, I moved from market segment A to market segment B, and now I buy quality instruments.
That’s something we really haven’t touched on thus far (market segmentation). I, like @alanza, think it’s unlikely that
because, if you even know what a Morphagene is, you are already part of a market segment that is unlikely to purchase cheap ripoffs. Given the choice between a Behringer clone and the real thing, you’re probably going to choose the real thing. You respect the craftsmanship involved in making the real thing, as well as the human beings involved in dreaming it up.
I agree, and this is very much a Segment B position. The cheap stuff lacks a certain poetry, which becomes more and more important as one gets more and more serious about making music. Or that has been my experience anyway. There are guys and gals out there banging tin cans together making better music than I could ever hope to make 
This has been a fun thread! Very stimulating.
