Brand Legacy: Shaping Light Through Design
Founded in 1874, Louis Poulsen operates under the philosophy of "shaping light through design," creating lighting products that merge aesthetic appeal with functionality. Its portfolio includes pendant lights, table lamps, and floor lamps, distinguished by their craftsmanship, innovative designs, and energy efficiency. The brand holds registered word and figurative trademarks across multiple categories, including lighting fixtures (Class 11), advertising (Class 35), and online services (Class 42).
Design Patent Risks: A Critical Consideration
Beyond trademark infringement, the lawsuit highlights nine design patents. Even if products bear different names, similarities in appearance to Louis Poulsen’s patented designs may constitute infringement. Sellers are advised to scrutinize their inventory, particularly for lamps with designs resembling the brand’s protected models.
Recommended Actions for Sellers
To mitigate risks amid Louis Poulsen’s dual enforcement efforts, sellers should:
- Conduct a thorough review of all lighting products, especially those resembling Louis Poulsen’s designs.
- Promptly remove listings with potential infringement risks.
- Seek guidance from intellectual property attorneys or cross-border legal experts for compliance verification.
- Prioritize IP compliance in product development and sourcing to avoid future disputes.
As intellectual property enforcement intensifies, adherence to legal standards is paramount for sellers navigating competitive global markets.
