CLEAN SEED SECURES MAJOR UNITED STATES PATENT COVERING MULTI-PRODUCT PRECISION DELIVERY ARCHITECTURE

The U.S. Patent and Trademark Office has issued Clean Seed Capital Group Ltd. the new patent titled Bulk Transfer Delivery System for Multiple Agricultural Products.

This newly granted patent reinforces the company's intellectual property portfolio supporting its advanced multiproduct input delivery systems. The patent protects the structural and mechanical architectures used to receive, isolate, route and transfer multiple agricultural inputs including seed, fertilizer and soil amendments from bulk storage compartments through controlled transfer pathways and into downstream metering environments.

The design includes independent flow management assemblies, modular transfer channels, diverter components and controlled routing geometry engineered to maintain product separation while supporting precise material handling under field conditions. These systems function as a core interface between bulk storage and zone-based metering platforms.

The patented system is broadly applicable across a wide range of seeding and input placement equipment, providing intellectual property protection that supports the continuing development and evolution of Clean Seed's multiproduct innovations.

Clean Seed's global intellectual property framework

Since inception, Clean Seed has pursued a disciplined strategy of protecting its precision seeding and multiproduct delivery technologies through a continuously expanding international patent portfolio. Over more than a decade, the company has secured broad patent coverage that safeguard the Smart seeder platform and the underlying metering, flow control and multiproduct input architectures that define its technological advantage.

These protections extend across key agricultural markets and technology categories, covering core systems such as electronic metering, multiproduct flow assemblies, controlled routing mechanisms and row-by-row variable-rate delivery frameworks. Collectively, these patents form a comprehensive and highly defensible intellectual property foundation, one designed to support long-term scalability, reinforce competitive positioning and uphold Clean Seed's leadership in precision application as global agriculture continues to evolve.

Graeme Lempriere, chairman and chief executive officer, added: "Yet another successful patent grant represents another important reinforcement of the technical frameworks that distinguish Clean Seed on the global stage. Our pursuit of strong, defensible intellectual property has been a priority since the company's earliest days, and the dedication of our engineering and development teams has been critical in achieving that objective. Their work continues to ensure that our precision input delivery systems are protected by a broad and rigorous IP foundation. As we expand our presence in key agricultural markets, this level of protection remains essential in supporting the company's positioning and the value we bring to the industry."

The U.S. Patent and Trademark Office granted the patent as U.S. patent No. 12,408,581, which will be in effect until June 30, 2042.
