Great, so show us some prior art from before 1992 that would have made this obvious? It should be easy since this is so broad of a patent claim as to border on the absurd.
Sadly, I don't have access to any software I used or developed back then, but it doesn't take prior art to make something obvious. You know how you used to sell people software upgrades before the internet? You sent them a piece of paper in the mail that they could fill in and send back. People replaced that process for pretty much every form of data entry way back in the days of green-screen terminals hooked up to mainframes. It's no huge leap of logic to do it for one more type of data entry.
So to paraphrase, "I can't explain why doing something in hardware is patentable but doing the exact same thing in software isn't, so I'll be cute to try and hide the fact that I just said something idiotic like software=speech."
"It's better to remain silent and be thought a fool than to open one's mouth and remove all doubt."
I didn't say *anything* like "software=speech". I simply stated two facts.
1) Mathematics is, *according to patent statues*, non-patentable subject matter.
2) All software *is* mathematics. (Not described by mathematics. Not modeled by mathematics. *IS* mathematics.)
If you don't understand the difference between hardware and software, it is hardly a failure on my part. That said, I'll try to rectify the situation for you.
Imagine a lit candle. That candle, and the flame can be modeled with incredible detail using mathematics (software). Is the candle the model? No.
If you light the candle, it produces light, heat, and several other waste products.
If you run the model, it tells you how much light, heat, and other waste products will be produced. It does not actually produce them.
That is the difference between hardware (the candle) and software (the mathematical model *of* the candle).
