Back in September we covered the news that Asetek had again won a patent infringement case against Cooler Master's parent company, CMI. To recap, last year Asetek was awarded damages from Cooler Master at a 14.5 per cent royalty rate following a unanimous decision in its favour. In response CMI demanded a new trial, which concluded in September this year, with Asetek winning enhanced damages of 25.375 per cent for infringing products sold this year.

We noted in the original HEXUS story, that AMD's Radeon R9 Fury X graphics card features an all-in-one liquid cooler, made for AMD by Cooler Master. Now AMD has been legally lassoed, as a Cease and Desist (C&D) order has been issued to it over the sale of these liquid cooled Fury X graphics cards.

The new liquid cooling litigation doesn't stop there. As GamersNexus notes, Gigabyte's GeForce GTX 980 WaterForce graphics card may also be removed from sale, as it uses a Cooler Master Seidon 120M LCS. GamersNexus received the following statement from Asetek over its latest patent moves:

“Asetek’s attorneys have recently sent cease and desist letters to Gigabyte, demanding that it cease selling Gigabyte's GeForce GTX 980 WaterForce (sold under at least model number GV-N980WAOC-4GD) because it contains the Seidon 120M found by the court to infringe Asetek’s patents.



Asetek’s attorneys have also written a cease and desist letter to AMD, demanding that it stop selling its Radeon R9 Fury X product, because it infringes Asetek’s patents. Our attorneys have had some difficulty obtaining a Gigabyte GV-N98TXTREME W-6GD, but we expect to receive and analyze one very soon for infringement."

Asetek patents 8245764 and 8240362 cover a liquid cooling circulation system with pump, thermal exchange chamber and heat exchanging interface, and the integration of the LCS with fan and radiator. At the time of writing it isn't clear what AMD and Gigabyte will do in the face of the C&Ds issued.
