The essential element here is using the time-dependence of the key

that element.
Well, the "hardware button" is a part of it. As well as being an
"application button."
As I understand it, somebody tried to patent the first
pencil with an eraser on the end. The patent was denied because it was
seen as a trivial combination of existing inventions.
Could be. I'm not familiar with it.
The question always is, if it was so 'trivial' then how come no one was
doing it before me?
I might not object to the Morse code being patented because it required
some statistical analysis that led to efficiency of the code.
It did? So an original 'inefficient' code would not be patentable?
(actually, my example was the telegraph, not morse code, and I don't know
for sure you can patent a 'code' or if that's a copyright kind of thing.)
I don't think that 'efficiency', or even practicality, is a consideration
as there are plenty of inefficient and impractical wacky things patented.
The market sorts those things out.
And
everybody was free to use some other code.
I don't think that's a consideration either. "I'm sorry Otto but you can't
patent your gasoline engine because there are no alternate gasoline powered
engines one is free to use." Actually, he lost his patent because there
*was* one.
It looks like this MS patent either tries to own the idea of using a
time-dependent binary signal as a code or tries to own a trivial
combination of existing inventions.
I'm probably not a good judge of what the 'minimum' criteria is as, judging
from some I've seen, I've missed a slew of patent opportunities with things
I consider simply solving the problem at hand.
