Puget Systems bit by patent that references their work (2014)

This patent scam is simple:

See cool thing on youtube, fix obvious design flaw and file a patent, threaten to sue original inventor.

Version 1 of the system didn't have any sort of radiator to deal with the oil heating up over time, something i think they had even pointed out in the version 1 video.

Version 2 did, but so did the patent filed by LiquidCool Solutions (that referenced their version 1 video in the patent).

So now they can only sale the original flawed version.
