The case was brought by the US-based intellectual property licensing company Xperi (formerly known under the names Rovi and TiVo).
Xperi claimed that Videotron, a subsidiary of Quebecor media, had illegally used patented technology related to four patents it owns.
But the court found each of the asserted claims of the four patents involved in the case were invalid.
In a statement Pierre Karl Péladeau, president and CEO of Quebecor, accused Xperi of practices “akin to those of patent trolls,” claiming that these practices “create no value for society and cost millions of dollars per year.”
Péladeau said: "Patents should reward innovation, not hinder it. We have shown that businesses should not give in to unjustified threats. Quebecor and Videotron will continue to vigorously defend their interests."
Meanwhile, Paul Davis, president of Adeia, the newly launched brand for the intellectual property (IP) licensing business of Xperi, said: "We are disappointed with today’s ruling, however it has no impact on our 2022 guidance. We are exploring all our options, including appealing the decision. We will continue to pursue our rights as we seek a mutually acceptable agreement with Videotron to allow the ongoing use of our patented technology.”
The full Canadian federal court decision remains subject to confidentiality requirements but should be released in the coming days, it was reported.
