Patent in US has only 15 years life. I have US patent personally on my name - not through any company etc. I can write patent application to US PTO my self and pay only standard fee. In special case -like pharmacy drug patent life can go up to 18 years. That is all. All those patent that you refer are too old and antiquated. Every manufacturing company incorporate in there product 2 parts. Part 1- is what customer need and willing to pay. Part 2 is add things that only increase price -costumer does not need that at all - and can not be option out. About " waffle iron " i think that all EMC2 is people that do just that. Do thing that other think impossible. > These seem to be the fundamental patents: > > http://softsolder.com/2012/06/29/fundamental-3d-printing-patents/ > > The patent documents include links to more recent patents that refer > back to them, so you can devote as much time as you wish to > determining > that the neat idea *you* just had has already been invented, > patented, > and reduced to practice.
