CLEAN SEED RECEIVES U.S. PATENT ALLOWANCE FOR RESIDUE MANAGEMENT TECHNOLOGY, FURTHER STRENGTHENING ITS AGRICULTURAL INNOVATION PORTFOLIO

The U.S. Patent and Trademark Office has issued a notice of allowance for Clean Seed Capital Group Ltd.'s patent application covering the company's innovative residue management system.

This notice of allowance represents another significant achievement in Clean Seed's intellectual property strategy and further reinforces the depth, breadth and commercial value of the company's growing portfolio of proprietary agricultural technologies.

The notice of allowance relates to U.S. patent application No. 18/557,669 entitled "Residue Management System for an Agricultural Row Unit Assembly" covering technology designed to improve residue handling and field performance at the row-unit level. Clean Seed will proceed promptly with its submission to have the patent granted.

The patented technology is designed to improve residue flow and debris management at the row-unit level, helping maintain seeding performance in challenging field conditions and varying crop residue environments while reducing interruptions caused by debris accumulation and field obstructions. The innovation complements Clean Seed's existing precision seeding technologies and further strengthens the company's growing portfolio of proprietary agricultural innovations.

The allowance comes at a time when Clean Seed is entering a new phase of commercial growth, advancing multiple commercialization initiatives including manufacturing activities with Mahindra and Mahindra Ltd., international market development programs, and broader deployment opportunities through strategic partnerships. The company believes a strong and expanding intellectual property portfolio remains a key component of its long-term growth strategy.

"This latest patent allowance is another important validation of the technology platform we have spent years developing," said Graeme Lempriere, chief executive officer of Clean Seed Capital. "Our intellectual property portfolio continues to advance and expand, creating meaningful barriers to entry while protecting the value of years of engineering, field validation and investment. As we continue advancing commercialization initiatives in multiple markets, this patent strengthens the foundation for future manufacturing, licensing and strategic partnership opportunities.

This latest allowance underscores Clean Seed's continuing commitment to innovation and its vision of developing and deploying next-generation agricultural technologies that help farmers produce more with fewer inputs while supporting healthier soils, improved sustainability outcomes and increased farm profitability.
