We actually have had major patent reform! Look into IPR review, the Alice Supreme Court decision, and the patent reform act of ... was it 2012? 2013?

The IP landscape is wildly different than it was when these patents were first filed. That they've held up under scrutiny implies they're not _total_ junk.

Also, it probably still needs reform. But my understanding from talking to lawyers (who I was paying, to be fair), it's better than it was.
