I’m sure the patent made sense at the time, but it seems pretty generic now. Additionally, shouldn’t the patent have expired at this point? Why is it still being enforced?
There is a period between filing a patent and actually receiving it. Maybe you’ve seen the phrase “patent pending” before. That likely plays a role here, if I read this right

That was my thoughts. Patents normally expire after 20 years, so how is a patent from the 80s still valid after nearly 40?
It expired recently https://patents.google.com/patent/US7072849B1/en
So how is it that a patent from 1989 only expired in 2023?
I not going to pretend I understand patents but it looks like IBM just asked for an extension and got it
