Narrative Opinion Summary
The case involves Minka Lighting, Inc., the exclusive licensee of U.S. Patent No. Des. 380,539, pursuing legal action against Craftmade International, Inc., alleging infringement of its ceiling fan design patent, unfair competition, and unjust enrichment. The United States District Court for the Northern District of Texas granted summary judgment in favor of Craftmade, concluding that its Solo and Céfiro fans did not infringe Minka's Viper fan design. The court ruled that the fans were not substantially similar in their overall visual impression. Additionally, Minka's claims of unfair competition and unjust enrichment were dismissed, as Craftmade did not infringe nor misappropriate Minka's designs. Minka appealed the decision, and the appellate court affirmed the district court's ruling. It upheld the claim construction approach of focusing on the ornamental features as depicted in the patent figures without deferring to an ordinary observer's perspective. The court also confirmed the district court's discretion in excluding certain evidence and reiterated that both the 'ordinary observer' and 'point of novelty' tests must be satisfied for determining design patent infringement. The court concluded that Minka failed to demonstrate any genuine dispute over material facts, warranting summary judgment in favor of Craftmade.
