This is unconstitutional. And not the fuzzy kind of constitutionality that pundits like to fight over. This is explicitly called out as forbidden in the U.S. constitution.
> No Bill of Attainder or ex post facto Law shall be passed.
Punitive damages are also not awarded as part of criminal cases. These would just be fines.
Lots of stuff the government does that pundits love to fight over is also called out as forbidden in the Constitution. Doesn't stop the government.
Problem is, coming up with a definition of "patent troll" that's 100% objective and can reliably differentiate between a benevolent NPE like ARM and a group of snakes like VirnetX is tricky. Too strict and you'll have some awful false positives. Too vague and you're reduced to arguing it in court, something prohibitively expensive.
IMHO The patent laws should be amended to require entities to both "articulate a solution" and "add value" to make the patent valid.
For ARM (as a NPE) their patent licenses are bundled with a low-power processor core design that provides a solution to licensees requirements. The core design adds value to the basic technology covered by the patent.
The VirnetX patents shouldn't be valid as they merely describe an element of a design, and not a particular means of implementation. This may fall under Sec. 112(f) "Means-plus-function" [0], but getting the patents invalidated is not easy.
The EFF have tried to bust "stupid patents" [1] somewhat successfully. Please donate to support this worthy cause.
From what I can tell, ARM started 30+ years ago and sold physical chips. I am missing when they morphed into mainly selling chip designs - and how were they able to make such a transition without the publicity of lawsuits.

Given that patent trolls usually retroactively sue for stuff they didn't have anything to do with, I'd say it would be very satisfying.
