The '200 Patent relates to a system architecture for liquid cooling of servers - in, for example, a data centre environment - in which the driving force for the liquid is provided in a distributed manner. The technology is commonly referred to as a "distributed pumping" architecture in the market for liquid cooling of data centres.
In its petition, Asetek Danmark A/S argued that all 21 claims of the '200 Patent were invalid in light of certain combinations of prior art. The PTAB instituted an IPR in response to Asetek's petition but, after hearing written and oral arguments from both CoolIT and Asetek, the PTAB ultimately rejected Asetek's challenge. As a result, all 21 claims of the '200 patent survived without amendment.
CEO, Steve Walton, commented: "We appreciate the PTAB's attention to detail throughout the IPR process and are thrilled that the PTAB ultimately recognized the validity of all 21 claims of CoolIT's '200 patent. CoolIT is fully committed to being the innovation leader in the liquid cooling market and to protecting our significant investment in innovation with our growing patent portfolio."
