You don't know what patent trolling is.
You are describing patent enforcement.
Patent trolling is when a small company/firm solely, only exists as a kind of legal container that currently owns ... well, usually a broad array of all kinds of patents that they bought from some other person or company at some point.
They then go around and do nothing other than see who they can shakedown for money, via threatening all kinds of lawsuits, which would be extremely expensive and time consuming to fight, so most companies just fold and settle.
Nintendo suing Palworld over copyright and patents?
That's not patent trolling.
Yes, the existence of patents and how IP law works is a complex and contentious topic, in general.
But... patent trolling?
It is a specific thing that occurs because of the current state of IP laws in the US, and basically everyone from any kind of relevant and related academic and/or legal background agrees that it is terrible and Congress should really revamp the laws to at least specifically fix it.
Patent and IP law are complicated.
Patent trolling is completely negative.
