Asetek filed a case against Coolermaster over the pumps that Seidon Series use. According to the accuser , Seidon Series by Coolermaster come with the models Seidon 120M, 120XL and 240M uses a pump units which look a lot like Asetek rebrands.
The case was filed on 31st January, 2013, concerning Patent no. 8,240,362 and 8,245,764.
Its too early to speculate if its a similar design or not as such patent infringement cases at times turn out to be the battle of the lawyers’ skills rather than facts at hand. It also should be noted that the basic idea behind closed- loop watercoolers hasn’t changed. This isn’t the first time Asetek filed a patent infringement case. Few months ago, Asetek sued CoolIT over similar counts as well.
But if Asetek does manage to pull a victory, they may not only end getting a huge compensation for the losses so far, but maybe even get a royalty for the Seidon units Coolermaster sells in the near future. This would also create issues for other brands who have their own CPU watercooling lineups, even maybe signing up Asetek as “OEM partner” just to save themselves from being sued. Therefore, the battle that both CoolIT and Coolermaster faces with the OEM CPU watercooling manufacturer would affect other closed-loop water cooling series from other brands as well.
