I call this a "Full Spectrum Lapidary 3D Image Scanner and Method", or a "3D Solid Scanner" for short. It uses polishing techniques vs. mechanical machining using cutting tools as other prior art cited:
... in particular has marketed a machine tool that creates solid 3D models using milling machines and layer imaging cameras. Software is used to reassemble the photographed layers into 3D SOLID models. I have cited prior art that precedes the Crump inventions as well. How do I determine freedom to operate issues in regard to these facts?
A "child patent" is a patent that derives some of it's novelty from previous work on a particular invention ... is my understanding.
Does anyone know of any other prior art such as the Visible Human Projects that was not referenced by the Crump patents or my patent?
