ROI Calculation Logic

Global annual economic losses from citrus greening disease are estimated to be in the tens of billions of dollars. By adopting this technology to accelerate resistant variety development, if an implementing company achieves annual sales of ~$33.5M (AI est.) in the relevant market, and assuming a ~3% reduction in disease-related losses, an annual economic loss reduction of ~$1.0M (AI est.) is anticipated. This could contribute to sustainable agricultural production and establish a long-term revenue base.

Speed to Market
6× faster than in-house development
This technology's infection method and efficacy have been established and demonstrated by a national research institute, indicating that the basic research phase is complete. With a willingness to license the patent, adopting companies could significantly shorten time-to-market compared to starting R&D from scratch. Specifically, by integrating it into existing breeding programs or cultivation systems, validation for resistant variety development could begin immediately, with prototype evaluation in approximately 6 months, followed by 1-2 years for practical application validation.
