Because software patents didn't exist at the time. Had they existed,
I am sure CDC would have.

In this particular decision, the patent exists. It now becomes AT&T's
job to prove that prior art exists and that therefore the patent
should be invalidated. To do this, they need to find prior art.
Finding previous attempts to run realtime data over packet-switched
networks is going to be interesting, and it'll be fun to see how their
legal staff does it.

Lots of folks cloned the System/360, from Amdahl to National Advanced
Systems. Most of them did much better jobs than RCA did. (RCA used
the S/360 instruction set but very different channel controller and
peripheral design, including the use of ASCII). They could do that,
because you couldn't patent or copyright an instruction set.
Now, I think the idea of a finite automaton COULD be patentable, but
Turing never filled out the paperwork...
