Judge Robinson construes claims relating to a heating, ventilation, and air conditioning system.

Judge Sue L. Robinson recently construed several claims of U.S. Patent No. 7,243,004, entitled “Self-configuring controls for heating, ventilating and air conditioning systems.  Carrier Corp. v. Goodman Global, Inc., et al., Civ. No. 12-930-SLR (D. Del. Aug. 14, 2014).  The following terms were construed:


  • “HVAC units”
  •  “data bus”
  • “central control”
  • “control algorithms”
  • “optimal control strategy”
  • “characteristic(s)” and “characteristic information”
  • “said control”
  • “connectivity kit”

Judge Robinson found that the following terms did not need to be construed by the Court, explaining that in light of the Court’s other claim constructions the jury would understand the limitations based on their plain and ordinary meaning:

  • “indoor unit” and “outdoor unit”
  • “determining an optimal control strategy for said indoor unit and said outdoor unit”
  • “selecting a particular one of said optimal control strategies”
  • “selecting one of said plurality of control algorithms”
  • “determine optimum control algorithms”
