The original title is about a legal case where the Federal Circuit reversed a preliminary injunction. Let me rewrite this for a mobile feed.

Short summary

The Federal Circuit reversed a preliminary injunction in Ridge Corp. v. Kirk NationaLease, finding the district court's claim construction raised substantial questions of noninfringement across three claim limitations. The Court also ruled Ridge failed to establish irreparable harm, citing no causal nexus between accused sales and pricing decisions. The decision underscores that patentees must show more than a plausible infringement theory to secure preliminary injunctive relief.
