Japanese OAT Agrio Patent Documents RADIX in Lettuce Nutrition Trials
A Japanese patent publication from OAT Agrio identifies SANANBIO RADIX as equipment used for controlled leaf-lettuce cultivation trials in 2021.
A Japanese patent publication made public on March 23, 2026, provides a detailed historical record of a lettuce cultivation test conducted by OAT Agrio Co., Ltd. Its description identifies a RADIX artificial-light plant-factory cultivation module manufactured by Fujian SANANBIO Technology Co., Ltd.
According to the patent's experimental description, the test was conducted in a controlled climate chamber at OAT Agrio's cultivation research facility, with lettuce transplanted on October 27, 2021 and assessed in November of that year. The growing module was operated under scheduled light and dark periods, controlled temperature and carbon dioxide, while the team examined cultivation compositions and tipburn-related outcomes.
The documentation is useful as a traceable Japanese commercial research application of the RADIX platform. It does not establish a commercial sales relationship beyond the equipment identified in the experiment, nor does it indicate that SANANBIO developed the fertilizer formulation being patented. OAT Agrio is identified as the patent assignee, and the legal status of any patent application should be checked independently before making intellectual-property claims.
