You left out quite a bit from that quote:

> Bates held research and teaching positions at Cornell, MIT, Carnegie Mellon, and Johns Hopkins universities in the US between 1980 until 2011. > > In 2005, Bates founded Singular Computing to commercialize various computing architectures.

Patent trolls don't commercialize anything, they just hold patents in order to attack people after they start using them.

Then there is also this:

> According to the complaint, Bates disclosed various technologies he had come up with to Google under a non-disclosure agreement on three occasions between 2010 and 2014.

I don't know if Singular's claims hold any ground, but based on the article it sounds nothing like a patent troll.
