This dataset identifies 13 patent families published between 2015 and mid-2026 that match the search scope of RAS water-treatment integration, IoT aquaculture integration, feeding-monitoring integration and general system integration within the relevant IPC classes. That is a small corpus compared to most agtech categories, which means the ranking and citation patterns here are more sensitive to individual filings than in a larger field. Anyone using this figure for competitive scoping should treat it as a scoped snapshot rather than an exhaustive count of every related filing worldwide.

The dataset shows no single dominant corporate assignee; instead, recent-year momentum is spread across individual inventors, an academic co-filer (Seshadri Rao Gudlavalleru Engineering College), and smaller companies like Impact9 Energy & Marine Ltd. The most-cited underlying technology, submersible pen systems, appears across several separately assigned filings including US and UK publications, which points to a shared design lineage rather than one company’s proprietary architecture. This is a field where influence is concentrated in a technology cluster rather than in a single filer’s portfolio.

The trend data shows 8 filings in 2020 against just 1 by the 2022 midpoint, a sharp drop that suggests a cluster of filings around a specific development window rather than sustained year-on-year growth. Filing counts in the final one or two years of any dataset are typically understated because publication lags filing by roughly 18 months, so some of the apparent decline after 2022 may partially reflect that lag rather than a genuine slowdown. Even accounting for that lag, the midpoint dip indicates this is not currently a fast-growing filing category.
