Top PTAB Judges Save 2 Claims In Signify Lighting Patent

By Editorial Team

Three top Patent Trial and Appeal Board judges have reversed the board's invalidation of a pair of claims in a Signify Holdings BV lighting patent, stating that the challengers to the patent improperly introduced new obviousness arguments in a reply brief.

The decision, made public on February 10, 2026, marks a significant development in the ongoing legal battle over Signify's patent for a configurable lighting system with patent number 10,299,336.

Background of the Case

The case involved challenges to the validity of the Signify lighting patent brought by Luminex Corporation and Menard Inc. before the Patent Trial and Appeal Board. The challengers argued that certain claims of the patent were obvious and therefore invalid.

In an earlier ruling in August, the PTAB had sided with the challengers and invalidated two claims of the patent. However, Signify Holdings BV appealed the decision, leading to the recent reversal by the three top PTAB judges.

Legal Implications

The decision by the PTAB judges to save two claims in the Signify lighting patent is expected to have significant legal implications for both parties involved in the case. It underscores the importance of proper argumentation and adherence to legal standards in patent challenges before the PTAB.

Furthermore, the ruling highlights the complexities and nuances involved in patent litigation, especially when it comes to issues of obviousness and patent validity.

Law Firm Representation

Notable law firms involved in the case include Jones Day, Leach & Walker, and Venable LLP, representing the various parties in the patent dispute.

Conclusion

The recent decision by the top PTAB judges to save two claims in the Signify lighting patent showcases the intricacies of patent law and the importance of thorough legal arguments in patent disputes. The ruling is likely to have a lasting impact on the ongoing litigation between Signify Holdings BV and the challengers, Luminex Corporation and Menard Inc.
