According to a report from Reuters, Nokia has this week become the first company to submit an amicus brief in support of Apple’s attempt to secure injunctions on several Samsung products. While the full contents of the brief have not yet been revealed, Reuters reports Nokia argued its position in a summary of the brief that was filed with the U.S. Court of Appeals for the Federal Circuit in Washington on Monday.

In an accompanying summary, however, Nokia argued that a trial court judge got it wrong when she denied Apple’s request for a permanent injunction.

In the filing on Monday, Nokia attorney Keith Broyles from Alston & Bird argued that U.S. District Judge Lucy Koh in San Jose, California, erred by ruling that Apple must establish a “causal nexus” between its patented feature and the demand for its phones in order to secure a permanent injunction.

Nokia argued that the rule “could cause wide-ranging damage to the United States patent protection landscape.”

Companies and advocacy groups will still be able to submit briefs on behalf of Samsung after the company’s written arguments in the coming weeks. Nokia said its decision to submit the brief is to “advocate for patent rights as a means of fostering innovation.” 

“Nokia has recently been involved in numerous U.S. patent lawsuits, as both a plaintiff and defendant,” Broyles wrote. “Nokia is thus both a significant patent owner that might seek an injunction to protect its patent rights, and a manufacturer in an industry in which patent owners routinely issue threats of injunctions for patent infringement.”
