Calgary, Alberta. October 5, 2022 – Liquid cooling technology company CoolIT Systems announced that on September 11, 2022 the United States District Court for the Northern District of California issued an Order that granted summary judgment of non-infringement for all of CoolIT’s past and current products in regard to Asetek’s U.S. Patent Number 8,240,362 (the ‘362 patent).  The court also found that CoolIT’s most recent pump design does not infringe either.

Following this summary judgment, CoolIT and Asetek settled all outstanding litigation between them, and CoolIT expects that the parties will soon submit a joint stipulation dismissing CoolIT’s and Asetek’s claims with prejudice.

On January 23, 2019, Asetek sued CoolIT for patent infringement regarding the aforementioned ‘362 patent and four additional U.S. patents, 8,245,764; 9,733,681; 10,078,354; and 10,078,355. This prompted CoolIT to defend and countersue Asetek for the infringement of four of CoolIT’s U.S. patents.  During the case Asetek added claims of infringement for two additional Asetek U.S. patents, 10,599,196 and 10,613,601.

Of these seven asserted Asetek patents, only the ‘362 patent was scheduled to be litigated in a trial scheduled for March 2023.  The remaining six patents had either been dropped by Asetek or stayed by the court pending ongoing appeals and proceedings by the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB).

As a result of the Order granting summary judgment of non-infringement on September 11, 2022, Asetek would not have had any remaining claims of infringement to present at the March 2023 trial.  In contrast, CoolIT would have been presenting its infringement claims against Asetek with respect to three of CoolIT’s patents relating to Split Flow technology.

In its Order, the court also found that all of CoolIT’s products containing its newest generation pump, which is found in CoolIT’s industry leading desktop liquid cooling solutions, do not infringe a claim limitation that is found in all of the Asetek patents asserted in the district court case.

CEO Steve Walton commented, “We appreciate the court’s attention to detail throughout the litigation and we are very pleased the court reached the correct result in determining CoolIT was not infringing.  CoolIT respects the intellectual property of others, but will take a stand when it believes it is not infringing.  We are most happy with getting back to the business of selling great products.”
