As we discussed a month or so ago, Formlabs has rasied over 3 Million on Kickstarter.com for their low cost 3D Printing project. Part of their ability to produce product at a low cost is due to be able to take advantage of patents that are expiring or have expired.
Techdirt has found some patent accusations against Formlabs may have over looked and have written a rather in depth piece on it.
"Upon information and belief, Formlabs and it sales agent Kickstarter knew or should have known about, or were willfully blind to, 3D Systems' extensive patent rights in the area of three-dimensional printing and stereolithography, including but not limited to 3D Systems' U.S. Patent No. 5,597,520 covering improved methods of stereolithographically forming a three-dimensional object by forming cross-sectional layers of an object from a material capable of physical transformation upon exposure to synergistic stimulation, by virtue of their sales of machines touted by Formlabs as using "stereolithography (SL) technology," which is a technology invented and extensively patented by 3D Systems and its founder Charles Hull."
For the rest of the artcle, go here:
