Whoa! It looks like sys is going to try to get rid of MB competition.I would be real nervous if i was a printer manufacturer using a Heated bed or enclosure right now, it sounds very general and i hope they dont really have a case..whats next slicers?

Patents in the suit are:

  • 5,653,925, Guessing it expires in Sept. 1995+20 = September 2015. Specifically, this calls out that the different fill settings infringe on this lawsuit. That's really icky.
  • 5,866,058, Guessing it expires May 1997+20 = May 2017. This relates to a heated print bed.
  • 6,004,124, thin walled, swaged extruder. Guessing it expires 1998+20 = 2018. The infringement is claimed on a thin-walled extruder with a heating block at the end.
  • 8,349,239 A patent on seam hiding. Doesn't expire until 2029! This is a seam hiding technique used by crossing the start and stop points so the extrusion doesn't start or stop on an exterior wall.

Thanks for the patents ccrome.
Interesting that they are hitting the soft and hardware sides.
