Related to this question on [3D Systems patent expiry][1], it appears that 3D Systems are raising a patent infringement lawsuit on the basis that Kickstarter and Formlabs:

> knew or should have known about, or were willfully blind to, 3D
> Systems' extensive patent rights in thearea of three-dimensional
> printing and stereolithography

This may be more on the legal side rather than the patent side, but surely they must have to first find out whether any of their specific patents are infringed, rather than just say, "We have a lot of patents in this field, you must have infringed some..."

What is the correct process here? Shouldn't they wait to see what technology is implemented in this process?
