Chief Judge Michael J. Davis of the U.S. District Court of Minnesota denied 3M’s preliminary injunction that would’ve blocked Avery Dennison from selling its OmniCube™ retroreflective-sheeting material. The preliminary-injunction motion was part of a patent-infringement lawsuit filed against Avery Dennison in June. Davis reportedly stated that Avery Dennison had raised a substantial question of validity with respect to the patents at issue and, according to the Court, “based on the likelihood of success on the [case’s] merits and that 3M will be irreparably harmed, the balance of harms and public interest tips in favor of Avery Dennison.”
