This dataset contains 826 published records dated from 2015 through the current partial year, drawn from a search combining cultivated-meat terminology with technical terms like cell culture, edible scaffold, growth medium and process equipment. Annual filings rose from effectively zero in 2017 to a peak of 187 in 2024, with 2025 and 2026 figures still incomplete because publication typically lags filing by around 18 months. Treat the total as a floor rather than a final count, since more records will publish and be indexed over time.

The dataset ranks 100 assignees by family count, with the leading company holding 81 records compared to 28 at fifth place and 16 at tenth. That gap shows a genuine leader but not a locked market: the top five assignees combined hold only 33.1% of all 826 records, and the top ten hold 44.1%, leaving more than half the field to companies with a handful of filings each. Several previously active filers also show sharp year-over-year declines in the most recent period, though publication lag makes it too early to call that a permanent slowdown.

The largest classification is C12N (microorganisms and genetic engineering), touching 61.1% of the 826 records, followed by A23L (foods and non-alcoholic beverages) at 49.5% and C12M (bioreactors and enzyme apparatus) at 25.1%. Protein-related classes A23J and C07K, plus fermentation class C12P, cover smaller but meaningful shares. Because a single record can carry multiple IPC codes, these shares add up to more than 100%, and they should be read as claim density signals rather than a strict partition of the field.

The class-level data shows enzyme and DNA testing claims (C12Q) at only 4.4% of records, far below the dominant cell-engineering and food-form classes — a gap relevant to anyone working on lot-release testing, quality control or analytical methods for cultivated products. Shelf-stability, edible-scaffold degradation behaviour and fat-delivery microstructures also show comparatively thinner coverage relative to the core cell-culture and bioreactor classes. These are areas where a well-drafted first claim has more room to stand without immediately colliding with dense prior art.

The most-cited record in this dataset, WO2020222239A1, and its related US filing US20220195359A1 (Aleph Farms, published 2022-06-23), describe cultivation systems and methods for large-scale production of cultured food, including growing non-human-animal adherent cells on edible scaffolds inside bioreactors that supply growth medium at a controlled flow rate. With 40 citations for the WO family member, it is a frequent reference point for later filers working on scaffold-based, bioreactor-driven cultivation systems. Anyone designing a similar large-scale cultivation process should read the granted claim scope directly rather than relying on the abstract, since citation count reflects influence within this searched corpus, not a guarantee of current enforceability.
