Uponor AB, a subsidiary of Uponor Corp. and an affiliate of Uponor North America, Inc., announced on March 18 that it has secured a favorable ruling from the Federal Court of Canada regarding its patent infringement case against Heatlink Group Inc. and PexCor Manufacturing Inc. Heatlink and PexCor are affiliated companies based in Calgary, Alberta that manufacture and sell PEX (crosslinked polyethylene) pipe. As a result of the ruling, Heatlink, PexCor and any subsidiaries, partners, employees, licensees, assigns, and agents must halt production, offering to sell, and sale of infringing PEX products, and will be ordered to pay yet-to-be-determined damages and costs.
Uponor AB filed suit against Heatlink and PexCor in 2011 in both the U.S. and Canada alleging that the companies infringed claims in a key Uponor patent relating to the manufacture of PEX pipe. In January, the suit went to trial in Calgary, Alberta, and on March 16, Justice Manson ruled in favor of Uponor AB. The action in the U.S. was previously stayed, pending the outcome of the Canadian litigation.
