It is fairly concentrated at the top. Across 18 ranked assignees and 49 total records, the top 5 hold 36 records, which is 73.5% of everything in scope, and the top 10 hold 47 records, or 95.9%. That leaves only a small number of records spread across the remaining eight ranked assignees, so a newcomer is far more likely to compete with one of a handful of dense filers than with a crowded general field.

Filing peaked at 19 records in 2019 and then declined; the clearest complete comparison runs from 16 records in 2021 to 4 in 2024, a drop of 75%. However, publication typically lags actual filing by around 18 months, so the lower counts showing for 2025 and 2026 are still incomplete rather than proof of a continued fall. The honest read is a documented pullback through 2024, with the more recent trajectory still unresolved.

The dominant classes are A61K (medicinal preparations), appearing on 63.3% of the 49 records, and A61P (therapeutic activity of compounds) on 44.9%, reflecting a therapeutic core. C12N (microorganisms and genetic engineering) sits underneath both application tracks at 28.6%. A second, agricultural cluster also shows up clearly: C05F and C05G fertiliser-related classes cover 24.5% and 20.4% of records respectively, and A01H plant-breeding classes cover 18.4%, meaning a real share of this filing activity is agricultural rather than human-health focused.
