What This Patent Covers

The patent was granted after successfully overcoming examiner rejections with precise arguments and amendments, demonstrating strong novelty and inventiveness. This robust patent clearly defines the technical features of applying carbon dioxide during specific periods in asparagus cultivation, providing a stable foundation for business development.

Competitive White Space

This patent focuses on CO2 application for asparagus. Licensees could develop complementary IP in advanced environmental sensors, AI-driven climate control algorithms for broader crop types, or integrated nutrient delivery systems, without conflicting with the core CO2 application method.

Economic Impact

estimated ROI · USD · AI analysis
ROI Calculation Logic

An asparagus farm adopting this technology could see a 20% increase in off-season yield. For a farm with ~$333K (AI est.) in annual revenue, where off-season sales are 40%, this translates to ~$133K (AI est.) in off-season revenue. A 20% increase in this segment could generate an additional ~$25K (AI est.) in annual revenue. This is estimated to improve annual profit by up to 30%, even after considering CO2 application costs.

Speed to Market
6× faster than in-house development
This technology, developed by a national research institution, has precisely defined CO2 concentrations and application periods, with proven efficacy. Establishing a similar cultivation method in-house would likely require several years of validation trials and data analysis. However, adopting this technology could significantly shorten that R&D period, allowing for early practical implementation within approximately six months of evaluation and trial. The optimized CO2 application protocol is already established, enabling immediate productivity improvements for adopting companies.

Beyond asparagus, this technology could apply to other high-value crops like tomatoes or strawberries where CO2 application is beneficial. Optimizing CO2 concentration and duration at specific growth stages could yield similar improvements in yield and quality, opening new market opportunities.
🌿 Smart Agriculture
Cultivation Optimization with AI & IoT Integration
Integrating this CO2 application protocol into AI/IoT-based environmental control systems could create smart cultivation systems that automatically optimize temperature, humidity, light, and CO2 levels. This has the potential to achieve both labor savings and maximized productivity simultaneously.
♻️ Circular Agriculture
Integration with CO2 Emission Sources
The technology could be adapted for circular agriculture models by supplying CO2 from industrial emission sources like food processing plants or biomass power plants to greenhouses. This could achieve both CO2 emission reduction and enhanced crop productivity, contributing to new ESG-focused business models.
Integration Roadmap — Estimated 12-Month Deployment
Phase 1: Technology Evaluation & Planning
Duration: 2 months
Evaluate detailed technical specifications and implementation requirements, confirming compatibility with existing facilities. Establish a concrete implementation plan and set objectives.
Phase 2: Pilot Cultivation & Optimization
Duration: 6 months
Implement the technology on a small scale or in a section of the greenhouse to verify CO2 application effects. Optimize CO2 concentration and duration based on cultivation data to suit the licensee's environment.
Phase 3: Full-Scale Deployment & Expansion
Duration: 4 months
Based on pilot results, initiate full-scale implementation and operation. Expand cultivation area, continuously monitor yield and quality data, and aim for further productivity improvements.
Technical Feasibility
This technology can be implemented with a relatively simple setup, primarily by adding a CO2 supply system to existing greenhouse facilities. The patent claims focus on specific CO2 application methods during certain periods, not requiring extensive facility modifications or specialized materials, thus posing low technical hurdles. It is highly probable that implementation can be achieved relatively easily by integrating CO2 supply functions into existing environmental control systems or by introducing general-purpose CO2 sensors and controllers.
Success Scenario
If this technology is adopted, greenhouse operations could achieve stable year-round asparagus supply. By maximizing yields, especially during off-season periods when market prices tend to be higher, annual revenue could increase by up to 30% compared to current levels. This could enable companies to differentiate themselves and establish a high-profit agricultural management model. Furthermore, stabilizing production planning is expected to contribute to improving employee working conditions.
