   Hi all,   
      
   I noticed that there seem to be many software patents for   
   machine translation. Yet I also noticed that one of the   
   early ones by Systran bhas expired:

   =systran&OS=systran&RS=systran   
      
   However I am wondering, wasn't machine translation as a   
   field begun in the 1960s? If so there should be many expired   
   patents.   
      
   Any info appreciated.
