Questionable Patents From MakerBot 56
An anonymous reader writes "OpenBeam USA is a Kickstarted company that builds open source aluminum construction systems (think high-quality erector sets). One of the main uses for the systems is building 3D printers, and creator Terence Tam is heavily involved in the 3D-printing community. He's now put up a blog post about some disturbing patents filed by MakerBot. In particular, he notes a patent for auto-leveling on a 3D printer. Not only is this an important upcoming technology for 3D printers, the restriction of which would be a huge blow to progress, it seems the patent was filed just a few short weeks after Steve Graber posted a video demonstrating such auto-leveling. There had also been a Kickstarter campaign for similar tech a few months earlier. Tam gives this warning: 'Considering the Stratasys — Afinia lawsuit, and the fact that Makerbot is now a subsidiary of Stratasys, it's not a stretch to imagine Makerbot coming after other open source 3D manufacturers that threaten their sales. After all, nobody acquires a patent warchest just to invite their competitors to sit around the campfire to sing Kumbaya. It is therefore vitally important that community developed improvements do not fall under Makerbot's (or any other company's) patent portfolio to be used at a later date to clobber the little guys.'"

And here they are, attempting to patent said extruder drive design: http://www.freepatentsonline.c... [freepatentsonline.com]
They're taking things from the open source RepRap community and attempting to patent them. Do not support MakerBot. Do not buy their machines. And advise everyone you know not to purchase their machines should they be considering it.

The author of original article/blog mentions towards the end that he submitted 3 prior arts to USPTO.

wouldn't a video demonstrating the tech published weeks before the patent was filed constitute prior art, rendering the patent non-novel and invalid?
You obviously don't understand the US patent system. The patent office basically rubber stamps patents (often helping the submitter reword things so they can pass it). The patent holder then uses it to shake down companies for money and/or destroy competition. Prior art or the validity of the patent is pretty much irrelevant when the system is stacked such that the cost to fight an invalid patent is outrageously expensive and completely unrecoverable. It has absolutely nothing to do with protecting inventors or, heaven forbid, promoting the progress of science and useful arts. It's all about destroying competition or making easy money for patent attorneys and their ilk.
