Oops. I was wrong. The 20-year term wasn't enacted until 1995. Patents 
filed before then usually have a 17-year term[1] (Note: this is all 
Google-fu, not a legal opinion. If you need one, please retain your own 
lawyer and ask him). It looks like Marching Cubes/Squares and Dividing 
Cubes *may* be safe to use. I'll look into futzing with the VTK build 
process to be able to compile just these classes.
