Toronto – Cimco Refrigeration, a division of Toromont Industries, announced an out-of-court settlement of several legal actions it took against Carnot Refrigeration for infringement of two Canadian patents related to CO2 refrigeration systems for ice rinks.

Cimco made the announcement on June 9 in a statement posted on its website,

One of the patents concerns a “CO2 Refrigeration System for Ice-Playing Surfaces,” and the other for a “CO2 Refrigeration System.” Cimco filed the suits after Carnot manufactured CO2 systems that were installed – or scheduled to be installed – at various ice-rink locations in Quebec.

Under the settlement, reached on June 4, Carnot has agreed to pay $1.8 million and a royalty to Cimco. Carnot has also agreed not to infringe any claim of the patents during their period of validity.

Carnot acknowledged in the statement that the claims made by the patents are “valid and enforceable.”

In addition, all other parties to the litigation have been released, and all municipalities named in the litigation are permitted to use CO2 refrigeration systems installed in their facilities. Carnot has also agreed to discontinue separate legal actions.

The agreement applies to the following facilities and municipalities, which are located in Quebec:

  • The Civic Centre, in Dollard-des-Ormeaux
  • Stade de la Cite des Jeunes, in Riviere-du-Loop
  • Centre Sportif Lacroix-Dutil, in Saint-Georges-de-Beauce
  • The Curling Club, in Roberval
  • Arena Cynthia-Coull, in Longueuil
  • Centre Sportif Rosaire-Belanger, in Riviere-Bleue
