Seriously?
Patents that old are still valid?
The system is completely and utterly broken and no one will fix it because....well money.
IBM's patent farm has yielded another bumper crop, with a Delaware jury awarding Big Blue $45 million in damages from mobile games maker Zynga. Jurors decided [PDF] last week that FarmVille maker Zynga, and its subsidiary Chartboost, had infringed on two IBM patents - including one from way back in the Prodigy days of 1989. …
IBM has been doing this for fifty-plus years.
Maybe there was some ancient period when it made sense, maybe not.
99% of patent cases are nonsense - the patent is invalid, not remotely what the system was made for.
And 99% of the time the biggest company wins, bludgeoning the opponent with lawfare.
Little guys never succeed in enforcing patents against big guys.
PTO has been invalidating its own issued patents for the last twenty years.
And it's all going on quietly - we seem to have worse problems to worry about.
What a mess.
