Legal counsel for HeatLink believe several errors were made in Justice Manson’s March 16, 2016, Federal Court of Canada ruling in Uponor’s patent infringement case, and have lodged an appeal of the decision. Twenty-five of the 30 claims of the Uponor patent asserted by Uponor were found to be invalid with the five claims that were considered valid focused on the travel of the pipe through the crosslinking zone. These claims do not relate to the quality of the pipe produced.

The evidence presented at trial demonstrated that no Uponor company in North America neither uses the process covered by the 376 patent, nor sells any PEX pipe in North America made by the process. HeatLink’s innovative product engineering team developed its own infrared technology process in 2002 and has been manufacturing high-quality PEX pipe since then for a broad range of plumbing and heating customers across North America.

In compliance with the ruling, HeatLink has halted the manufacture and sale of the products affected by the Canadian court’s judgment, but is conducting business as usual throughout North America with the continuing sales of other HeatLink products.

“We are a family owned and managed company and we care deeply about our customers and staff,” says Manfred Schmidt CEO of HeatLink. “Our focus is on meeting the needs of our customers, and ensuring they are able to run their businesses effectively. We believe the matter will be resolved in our favor on appeal, and have asked that the appeal be heard in June of 2016.”
