Narrative Opinion Summary
This case involves an appeal by Kelley Company against a district court decision awarding damages for patent infringement to Rite-Hite Corporation. The central issue was whether Rite-Hite could recover lost profits for sales of its ADL-100 restraints, which were not covered by the infringed patent for vehicle restraints. The court held that, under 35 U.S.C. § 284, Rite-Hite could claim lost profits for the ADL-100 as the damages were foreseeable and compensable. The court also affirmed the reasonable royalty damages for sales of patented products but vacated the award related to dock levelers, as they did not meet the entire market value rule. The ISOs, who intervened claiming exclusive licensing rights, were found to lack standing to sue as their licenses did not confer the right to exclude others. The case was remanded for recalculating damages excluding dock levelers, and for dismissing the ISOs' claims. The ruling emphasized the statutory mandate for full compensation for patent infringement while respecting the limits of reasonable liability and the right to sue.

Application: The court vacated the award for dock leveler damages as they were not functionally related to the patented invention under the entire market value rule.
Reasoning: The functional relationship required for recovery under the entire market value rule is not established, leading to the conclusion that the district court erroneously included dock leveler sales in the damage award.

Reasoning: In this case, the district court found Rite-Hite successfully established 'but for' causation under the Panduit test, enabling a claim for lost profits related to the ADL-100.

Reasoning: The appellate court's review, conducted en banc, focused on the legal compensability of such damages under 35 U.S.C. § 284.
Reasonable Royalty Calculationssubscribe to see similar legal issues
Application: The district court's reasonable royalty rate was affirmed, rejecting arguments that it was excessively high, emphasizing that the rate need not be limited by the infringer's profit margin.
Reasoning: To challenge the awarded damages, one must demonstrate that the amount is either excessively high or low relative to reasonable estimates. The district court performed a hypothetical negotiation analysis.
Standing to Sue for Patent Infringementsubscribe to see similar legal issues
Application: The court determined that ISOs lacked standing to sue for patent infringement due to their non-exclusive licenses, as they did not have the right to exclude others from using the patented invention.
Reasoning: The court agrees with Kelley, stating that the ISOs must be dismissed for lack of standing. The statutory right for a patentee to seek remedies for infringement requires legal title at the time of infringement.
