Some people regard ex Microsoft CTO Nathan Myhrvold, now with Intellectual Ventures, as a patent troll who is trying to corner the market on 3D printing.
A quick read of the actual patent looks more to me like he’s thought up a service where folks can register their designs so that print shops can do a quick check of whether they may print the product without infringing on the copyright of others — and which may even act as a means to pay licensing fees to recreate the product. Those are probably good ideas — but only if the registration of designs are properly attributed and challenges are open to due process. If it goes the way of copyright takedown notices on the web, then it’s another shackle on innovative small businesses favouring, instead, faceless corporations.
