Nova Chemicals Corporation v. Dow Chemical Company, et al. (39439)

Posted on: 2022-07-05



In 2014, the Federal Court, in the liability phase of the trial, held that the respondents’ (collectively “Dow”) 705 Patent for fabricated products made from ethylene polymer blends was found to be valid and infringed by a product manufactured by Nova Chemicals Corporation (“Nova”). The 705 Patent issued in 2006 and expired on April 19, 2014. Dow was held to be entitled to damages under the Patent Act, R.S.C. 1985, c. P-4, and had to elect either an accounting of Nova’s profits or damages sustained by reason of Nova’s infringement under s. 55(1) of the Act. The quantum of that award was to be assessed by reference. Dow elected an accounting of profits. The reference judge was required to determine the manner in which damages payable to Dow pursuant to ss. 55(1) and 55(2) of the Act should be calculated. The principles articulated by the reference judge allowed for the calculation of the accounting of profits to be disgorged by Nova and made payable to Dow. That decision was upheld on appeal.
