What This Patent Covers

This patent protects a clear method for reducing methane emissions from paddy fields by selecting and cultivating deep-root rice varieties, defined by four specific claims. It was granted after a standard examination process, citing four prior art documents, and its early examination request highlights the high novelty and inventiveness of the technology, providing a robust legal foundation for commercialization.

Competitive White Space

This patent focuses on selecting and cultivating deep-root rice. It does not cover specific genetic modification techniques for deep-root traits, nor does it claim novel methods for soil amendment or water management that could further enhance methane reduction. Licensees could explore these areas for complementary IP.

Economic Impact
~$800K/year in environmental cost reduction or revenue is estimated for an adoption of 5,000 hectares (est.).

ROI Calculation Logic

Implementing this technology could reduce methane emissions from paddy fields by approximately 2.5 t-CO2e per hectare per year through deep-root rice cultivation. If 0.25% (5,000 hectares) of the estimated 2 million hectares of domestic paddy fields adopt this technology, an annual reduction of 12,500 t-CO2e is projected. Valuing carbon credits at ~$65 per t-CO2e (AI est.), this could generate ~$800K/year in credit revenue or cost savings (AI est.).

Speed to Market
5× faster than in-house development
This technology is based on the clear technical principle of selecting and cultivating deep-root rice, demonstrating high compatibility with existing rice breeding and agricultural techniques. Extensive research on deep-root traits in various rice varieties can be applied, significantly shortening the technology introduction phase. Focusing on variety selection and cultivation optimization rather than genetic modification also enhances social acceptance, accelerating time to market.
