Asetek, which manufactures closed-loop liquid cooling solutions that are re-branded by several companies, filed a patent-infringement lawsuit against Cooler Master alleging infringement of multiple patents held by Asetek. Cooler Master's recently launched Seidon line of closed-loop liquid CPU coolers are points of contention for Asetek, as it claims the products infringe upon patent numbers 8,240,362 and 8,245,764, held by the company.

Seidon 120M and 240M may have been launched late January 2013, but had been pictured much earlier, in September. Ahead of its launch, Asetek claims it had contacted Cooler Master with a cease-and-desist order, but it claims the latter didn't respond satisfactorily, going ahead with the launch. The case (Civil Action No. 3:13-cv-00457-JSC) will now be heard by a US Court. Cooler Master's defense could stress on the point the essential design of a CPU liquid cooler hasn't changed for decades. Other liquid cooling makers, which aren't particularly as big as Asetek (which sells liquid cooling solutions to even the server and defense industries), will be closely following the case.
