But the big name here really is Cooler Master. Asetek, the company that provides many of the industry's LCS coolers for Corsair and NZXT, had a win in a patent infringement case against Cooler Master (CMI) in 2014. Late last year Asetek took Cooler Master's parent company, CMI, to court for infringing its patents on all-in-one liquid coolers. 

Asetek won the court case, with the jury unanimously ruling in favour of Asetek, and was awarded damages from Cooler Master at a 14.5 per cent royalty rate. CMI obviously thought it had grounds to appeal and demanded a new trial.

The court "denied CMI's demands, and instead substantially followed Asetek's requests and issued a permanent injunction barring CMI and its parent Cooler Master from selling certain infringing products into the Unites States". Another unfortunate upshot of CMI's re-trial is that the judge awarded Asetek enhanced damages at a 25.375 per cent royalty rate on all infringing products sold this year. CMI can and may decide to appeal again.

The following Cooler Master products are effected by the new court ruling:

• Seidon 120V  / Seidon 120V Plus / Seidon 120M / Seidon 120XL / Nepton 140XL / Seidon 240M / Glacer 240L / Nepton 280L

The impact and effect of the trial could advance over Asetek and CMI. AMD's Radeon R9 Fury X graphics card features an all-in-one liquid cooler, made for AMD by Cooler Master. It remains to be seen what will happen to these graphics cards being marketed and sold in the US.
