The dataset ranks 38 companies and individuals by patent family count, and the leading assignee holds 12 of the 87 records in scope. The top 5 assignees together hold 43 records (49.4% of the field), and the top 10 hold 65 (74.7%), so ownership is concentrated among a relatively small group of industrial biotech firms and university research groups. Beyond that group there is a long tail of entities with one or two filings each, typically individual inventors or smaller research teams.

Filing activity peaked at 11 records in 2018 and the tracked window from 2021 (6 filings) to 2024 (0 filings) shows a full -100% move, which looks like a sharp slowdown. However, publication typically lags filing by around 18 months, so the 2025-2026 figures are still incomplete and should not be read as proof the field has stopped. A fair read is that the field has cooled from its 2018 peak, with the most recent trend still uncertain.

Almost all records touch C12N, the class covering microorganisms and genetic engineering, at 98.9% of the 87 records, and C12P, covering fermentation and enzymatic synthesis, at 77.0%. Application-specific classes like brewing (C12C) and baking (A21D) each sit around 12.6%, meaning most patented work is on the organism and fermentation process itself rather than on a specific downstream product. This split matters for anyone deciding whether to file on the strain or on a particular use case.
