Aspex has sued Safilo for violation of one of its patents. The Canadian company, known for its magnetic eyewear clips, had already taken Safilo to the Canadian high court in Québec last May. Then on Sept. 21 Aspex pursued its case against Safilo USA, in defense of its US patent RE37, 545E in the New York federal court. The Québec court had issued an interim injunction which forbid Safilo Canada from selling the contested « Click-on » product and demanded that the products already sold be re-called.
