While I am unsure on the matter, I think nChain has the largest portfolio of patents in the crypto currency and Blockchain space. Not knowing your definition of "patent troll" -- not exactly a dictionary term -- I really have no way to respond to your question.
Quote
A patent troll uses patents as legal weapons, instead of actually creating any new products or coming up with new ideas. Instead, trolls are in the business of litigation (or even just threatening litigation). They often buy up patents cheaply from companies down on their luck who are looking to monetize what resources they have left, such as patents. Unfortunately, the Patent Office has a habit of issuing patents for ideas that are neither new nor revolutionary, and these patents can be very broad, covering everyday or commonsense types of computing things that should never have been patented in the first place.

Great. By that definition, neither nChain nor CSW are patent trolls.
I'm still on the fence about that.
The fact that CSW submitted for copyright something that has been in the public domain for years (the bitcoin whitepaper)
(I realize there is a difference between copyright and patents - but I am discussing the conduct rather than the legal terminology)
So copyrighting something that is public domain, taking out over a thousand patents, threatening existing competition....
While it may not be a complete picture or I may have misinterpreted it. It certainly has the appearance of heading the way of a patent troll.

CSW is not Satoshi and BSV is not Bitcoin.
