[ODE] Quickstep and patents

I too, am Mathematician. It seems my question still remains: is it a  
patent on "the sum of all parts" or "all parts individually"??
(If BMW has a patent on their engine, they dont hold patents on every  
single screw. Someone brought the car idea up.)

I am not a lawyer (see above), but doesnt the right to sue someone  
vanish after a while, IF you know other ppl are using your patent  
"illegally"? So it becomes "customary law"? Agaia knows about ODE for  
quite a while and they didnt do anything against it.

I feel this might become very serious. Anyone knows a good lawyer? We  
have one for our software contracts, but that will cost...

How far does this patent reach, does it reach from the US to Europe?  
I have customers all over the world that use my product.
