What This Patent Covers

This patent protects a specific yuzu blended fragrance composition with anti-stress effects, having undergone rigorous examination and amendments to establish clear differentiation from prior art. The claims focus on the core combination of five specific components, providing a robust and stable intellectual property foundation for licensees.

Competitive White Space

This patent specifically covers a yuzu fragrance blend for anti-stress. White space exists in developing novel delivery systems for these compounds or exploring other natural extracts for synergistic effects in mood enhancement beyond stress reduction.

estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming a licensee can set a unit price $3.50 higher (AI est.) for wellness products incorporating this blended fragrance compared to existing products. Projecting annual sales of 300,000 units, this could generate an estimated annual revenue increase of ~$1.0M ($3.50/unit × 300,000 units). This is based on the growing stress care market and consumers' increased willingness to pay for natural, functional fragrances.

Speed to Market
8× faster than in-house development
This technology has identified specific yuzu blended fragrance components with anti-stress effects, and its basic mechanism of action is established. This significantly shortens the development timeline compared to starting R&D from scratch. By bypassing component discovery and initial efficacy validation, licensees can rapidly transition to product development and market launch, saving approximately 3.5 years of development time. Patent approval also reduces intellectual property risks.
