Claim 1 Exemplary Evidence of Infringement by E

[1pre] A method for cooling a room configured to house a plurality of computer systems, said method comprising: 

Evoque’s data centers use a method for cooling a room configured 

computer systems. For example, Evoque uses Vertiv (Liebert) cooling units in each cocooling units are controlled by Liebert’s iCOM Intelligent Comsystem.
