Even I have heard of this kind of thing, especially in the context of
software patents.

What irks me about the Solidscape situation is that they have, as far
as one can tell, no intention of adapting the wax-drop/soluble-support
method to produce larger objects. (This makes a certain amount of
sense, since there's so much competition in the 2"-12" size range, but
in my opinion there's a niche open in that no process makes completely
burnable parts _and_ fully supports undercutting. Which, of course,
is what I need.)

Obviously I don't want to step on anyone's legal toes, but if
Solidscape is committed to making and protecting a narrow application -
to micro objects only - of a method that could be more broadly useful,
I hope I can be forgiven for feeling that a resource is being wasted.
