It appears the inventor still had some sort of proprietary rights with regards to Patents he worked with at ML.
More than likely he could not compete until a period of time had elapsed.

You'll notice a few down the bottom that refer to ALGOFORCE and not ML.
Seems he may have been holding back a few things while at ML?!
