Unless you have a source showing things have changed for the better, I don't see how the age of my examples is relevant. Especially since they may have been granted in the 90s, but expired only very recently.

You can find sources about the changes in patent law since the 90's. For the most salient example: CLS Bank v. Alice.

Many of the abuses since then have been corrected. That's how the age is relevant.
