The loss of the '161 Patent removes a key barrier to competition on Deckers' flagship UGG boot design. Monitor for an appeal notice to the Federal Circuit; if no appeal is filed within 30 days, the competitive risk is cemented. The ruling also increases pressure on Deckers to settle or license, though no settlement terms were discussed.

Executive Summary
Deckers Outdoor Corporation lost its motion for a new trial on patent validity after a jury found its '161 Patent invalid for indefiniteness, lack of enablement, and/or obviousness. The denial is final at the district court level, cementing the loss of patent protection for Deckers' UGG boot design against competitor Quince. This removes a key IP asset and opens the door to continued competition on the core product, though the financial impact is not quantified in the ruling.
Court Ruling Details
Key Facts
- Deckers' motion for new trial on the validity of U.S. Patent D927,161 was DENIED in full.
- The jury previously found the '161 Patent invalid (indefinite, non-enabling, functional, and/or obvious) despite finding infringement by Quince.
- Invalidity is a complete defense to infringement; final judgment was entered for Quince.
- The Court ruled that submitting indefiniteness to the jury was not legal error, or any error was harmless.
- Deckers' objections to expert testimony and prior art admission were rejected as waived or within the Court's discretion.
- This is a final district court ruling; Deckers can appeal to the Federal Circuit.
Financial Impact
Loss of patent protection on a core design patent (UGG boot) — financial impact not quantified in the ruling.
Risk Factors
- Appeal to Federal Circuit could take 1-2 years and may not succeed; the ruling is well-reasoned.
- Loss of patent protection may allow Quince and other competitors to sell similar shearling boots, pressuring UGG brand pricing and market share.
- No damages were awarded to Deckers; the company bears its own litigation costs.
