What This Patent Covers

This patent protects specific oligonucleotide sequences essential for detecting buckwheat downy mildew pathogen (Peronospora ducommeti) and their use in PCR-based detection methods. The claims were refined through examination, establishing a robust and stable right with low invalidation risk, having successfully overcome examiner objections.

Competitive White Space

This patent primarily covers the specific oligonucleotide sequences and PCR methods for detecting buckwheat downy mildew. White space exists in developing novel therapeutic or preventative treatments for the disease, or extending the detection methodology to other specific pathogens affecting buckwheat or other specialty crops.

Economic Impact
~$100K/year estimated buckwheat yield loss reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Buckwheat downy mildew can cause 5%–20% yield loss. Assuming a domestic buckwheat production value of ~$200M (AI est.) and a 5% reduction in yield loss through early diagnosis and spread prevention, the potential loss avoidance is ~$10M (AI est.) annually. If an adopting enterprise captures 1% of this benefit, the estimated economic impact is ~$100K (AI est.) per year.

Speed to Market
6× faster than in-house development
This technology is built upon already identified oligonucleotide sequences for specific detection of buckwheat downy mildew pathogen and utilizes the widely adopted PCR method. Technical validation is complete. Integration into existing inspection facilities and compatibility with commercial PCR equipment are straightforward, requiring no major new development. This established protocol allows licensees to transition to practical application within approximately six months, enabling rapid market entry.
