Metaballs - regarding patent. 2005-04-14 - By Joe Saltzman
Back
I just did a simple google search.... this is what I came up with.
Seems like GE may hold the patent -- they might have become aggressive in its
enforcement -- do you want to take a chance on an infringement case with GE?
Could you afford to fight such a case? I don't think most people could do.
Just another reason why software patents are not a good thing IMHO.
Cheers,

I've heard this before and it seems rather absurd. Metaballs were in Soft 3D
and Houdini before Rem Inforgaphica patented them.
I have never heard of patents being retroactive.
