That's hardly the case here.

> The patents were at the center of a legal dispute involving Lenovo in 2020, in which the computer maker claimed Nokia did not fully disclose its intellectual property interest to the ITU and ISO while the bodies were working to standardize H.264. That lawsuit was settled one year later, with Lenovo and Nokia agreeing on a cross-licensing agreement.

That looks like patent trolling to me: sue someone who’s not really in the business and settle so when you sue a bigger player you can tell the judge that this other company did the right thing and paid for your incredibly critical technology.
