What This Patent Covers

This patent protects a method for detecting specific DNA polymorphisms in citrus plants for male sterility identification, along with the primer set used for this detection. The claims were rigorously examined and strengthened through a robust prosecution process, resulting in a strong, difficult-to-invalidate right.

Competitive White Space

This patent focuses on male sterility. Licensees could expand by developing DNA markers for other desirable citrus traits like disease resistance or fruit quality, or adapt the primer design methodology for genetic screening in other fruit crops.

ROI Calculation Logic

Assuming annual personnel costs of ~$350K (AI est.) for male sterility evaluation in citrus breeding, this technology could achieve over a 30% reduction through improved efficiency and early selection. This translates to over ~$100K/year (AI est.) in direct cost savings. Additionally, accelerated market entry for new varieties due to shorter breeding cycles could avoid over ~$100K/year (AI est.) in opportunity costs, totaling over ~$200K/year (AI est.) in economic benefits.

Speed to Market
10× faster than in-house development
This technology benefits from already established specific DNA sequences for male sterility identification in citrus plants and a validated primer set for detection. This eliminates the need for licensees to develop proprietary markers from scratch, allowing immediate protocol application in existing molecular biology labs. With proven primer sets and detection methods, the time from technology adoption to full operation is significantly reduced, enabling rapid business impact.

This technology could be applied as an efficient screening method to identify successful gene-edited individuals in new variety development. This has the potential to accelerate genome editing breeding pipelines by 25%.
Integration Roadmap — Estimated 21-Month Deployment
Phase 1: Technology Evaluation & Protocol Establishment
Duration: 3 months
The licensee's research team evaluates the technology, confirms compatibility with existing equipment, and establishes optimal in-house identification protocols.
Phase 2: Validation Trials & Pilot Implementation
Duration: 6 months
Conduct validation trials for male sterility identification using actual breeding materials. Identify and optimize operational challenges through small-scale pilot deployment.
Phase 3: Full-Scale Operation & Accelerated Breeding
Duration: 12 months
Based on validation results, fully integrate this technology into the entire breeding program. This aims for continuous shortening of new variety development cycles and enhanced market competitiveness.
Technical Feasibility
This technology is a molecular biology method that detects specific single nucleotide polymorphisms (SNPs) in citrus plants using a primer set. It can be implemented with standard molecular biology lab equipment such as PCR machines and DNA sequencers. Utilizing the patented primer set lowers technical barriers, ensuring high compatibility with existing testing infrastructures. No major new equipment investment is required, suggesting a relatively smooth adoption process.
Success Scenario
Adopting this technology could shorten the selection period for male sterile citrus individuals from several years to a few months in new variety development. This is expected to improve development pipeline turnover by 20% annually and accelerate time-to-market by an average of one year. Consequently, it could generate new annual revenue opportunities and establish a competitive advantage.
