What changed
The USPTO has published patent application US20260109940A1, establishing prior art status and securing the June 17, 2025 filing date for the claimed biostimulant production methods and systems. The application covers a bioreactor-based process for producing nitrogen-efficient microbial biostimulants with containers arranged in series, aqueous feedstock transfer, and working fluid management to maintain nitrogen use efficiency-promoting microbial strains.
Affected parties include agricultural biotechnology firms, fertilizer manufacturers, and companies developing nitrogen-efficient agricultural products, who should monitor this application as it progresses toward potential grant. The claimed bioreactor systems and methods for nitrogen use efficiency promotion may have implications for freedom-to-operate assessments in the agricultural biologicals space.

Abstract
The present disclosure provides methods and systems for production of biostimulants that promote nitrogen use efficiency in plants. Embodiments described include methods of making a biostimulant composition in a bioreactor system that includes two or more containers arranged in series. The bioreactor system may include an established population of a nitrogen use efficiency-promoting microbial strain. The method may include operating the bioreactor system by transferring into the system an aqueous feedstock that comprises a microbial consortium, transferring working fluid between containers of the system, and collecting a product. The method may further include maintaining a concentration of a nitrogen use efficiency-promoting microbial strain in the system.
