>The Polaroid patents and the Xerox patents are the only cases of really fundamental critical patents that I can recall that have held enough to insure a monopoly in recent years. Can anybody think of many others?

Canon has some laser printer patents that have ALMOST eliminated any real competition [Canon makes the print engines for HP's laser printers; Lexmark has licensed some of these patents].

Canon, HP and Epson among them have a set of patents that almost eliminate any additional entrants from making inkjet printers. Again, Lexmark has a relationship with Canon, and has done just enough on their own to remain viable [but just barely, in my opinion].

I'm sure that there are other cases, but they are fairly rare, I agree.
