Leading Jurisdiction
Filing growth compares 2021 (9 records) with 2024 (6) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 64 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
Black soldier fly larvae bioconversion turns organic waste streams into protein, lipid and fertiliser outputs, and the patent activity tracked here spans 64 published records filed between 2015 and mid-2026. The search captures substrate composition, larval growth rate, protein yield, frass fertiliser, rearing climate control and regulatory feed approval — the operational and regulatory levers that separate a lab process from a permitted commercial one. Families, not raw document counts, are the unit used for the assignee ranking, which neutralises continuation filings and multi-jurisdiction duplicates.
Filing rose to a peak of 15 records in 2020, then eased back; the most recent complete comparison shows a 33% drop from 2021 to 2024. Because publication typically lags filing by around 18 months, 2025 and 2026 figures will fill in over time and should not yet be read as a slowdown.

The Data
Filing trends and technology composition
Two views of the same 64-record dataset: filing activity by year, and where those records sit across IPC subclasses. Each record can carry more than one IPC class, so class shares add up to more than 100%.
A 2020 peak followed by a real but partial decline
Filings climbed from 6 in 2017 to a peak of 15 in 2020, then fell; 2021 to 2024 shows a 33% drop. Treat 2025 and 2026 as undercounted rather than as evidence the field has cooled, since publication lag means recent filings haven't surfaced yet.
Protein and feed classes dominate; husbandry and biocide claims trail
A23J (proteins and food peptides) leads at 43.8% of records, followed by A23L (foods and beverages) at 39.1% and A23K (animal feed) at 35.9%. Fertiliser-related C05F and biocide-related A01N each sit at 18.8%, and A01K (animal husbandry and fishing, covering rearing infrastructure) is the smallest tracked class at 17.2% — a gap worth noting given how central rearing climate control is to commercial viability.
Shares are the percentage of the 64 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

PROTIX B.V.
Maillard reaction products of enzymatically hydrolysed water-soluble black soldier fly larvae protein are obtained via a method that provides an aqueous water-soluble larvae protein composition, mixes it with at least one peptidase, heats the mixture, and terminates hydrolysis by heat-inactivating the peptidase — producing the hydrolysed protein output.Filed by Protix B.V., published 2025-09-04; a continuation of the same hydrolysate line as the most-cited record in this dataset, WO2021054824A1.

What the numbers mean for a filing decision
Three patterns stand out once the records are grouped by assignee, year and IPC class.
Concentration
85.9%
of 64 records held by top 5 assignees
This is a leader-plus-long-tail field, not an open one
The leading assignee alone holds 25 of the 64 records in scope, and the top five combined account for 85.9% of all records. Filing into core protein-hydrolysate or lipid-fractionation claims means filing against dense prior art from a small set of incumbents.
Ranked leaders, 15 companies total
Momentum
-33%
2021 to 2024 filing change
A real cooldown from the 2020 peak, not a data artefact
Filings peaked at 15 in 2020 and the 2021-2024 comparison shows a 33% decline — a genuine pullback from the post-2020 surge, distinct from the incomplete 2025-2026 tail caused by publication lag.
Peak year 2020, 15 records
Technology mix
43.8%
of records touch A23J protein claims
Protein and feed applications crowd out rearing infrastructure claims
A23J, A23L and A23K together dominate the class distribution, reflecting where commercial value is claimed — end products. A01K, covering husbandry and rearing methods, is the smallest major class at 17.2%, suggesting climate-control and rearing-hardware claims are comparatively less contested.

Players
Who is filing, and where the gaps sit
Fifteen assignees make up the ranked leaders in this dataset. The leader holds 25 records; by tenth place that falls to 1, and momentum data shows several formerly active assignees — including academic filers — recording zero filings in the latest year.
Leader
25 records
of 64 total
A single assignee anchors the field
The top-ranked assignee holds 25 of the 64 records in scope — well ahead of fifth place at 3 — and its portfolio centres on protein hydrolysate methods, the same claim family as the most-cited record in this dataset.
Top 5 combined: 85.9%
Mid tier
3 to 1 records
fifth through tenth place
A thin middle tier before the tail thins out
Filings drop sharply after the leader: fifth place holds 3 records and tenth place holds just 1, with the top 10 combined covering 95.3% of all 64 records. Academic and research-institute filers appear through this tier alongside industrial players.
Ranked leaders, 15 companies
Momentum
0 in latest year
for several tracked assignees
Recent-year activity has gone quiet even among prior leaders
Multiple assignees, including the field's largest filer, show zero filings in the latest tracked year, with some recording a -100% year-on-year change. This is consistent with the broader 2021-2024 decline rather than a single company exiting.

What's Next
Where to take this analysis
The dataset points to a concentrated core and a thinner set of adjacent claim areas. Two directions are worth pursuing depending on whether the goal is freedom-to-operate or new filing.
Map freedom-to-operate against the leading hydrolysate portfolio
With one assignee holding 25 of 64 records and centred on protein hydrolysate claims, any new protein-processing filing should be checked against that portfolio's claim scope before drafting.
Run a claim comparison in EurekaExplore the rearing-infrastructure and frass-fertiliser gaps
A01K and C05F carry the lowest class shares among the tracked subclasses, suggesting rearing hardware and fertiliser formulation claims are less occupied than protein and feed claims.

FAQ
Common questions on this landscape
One assignee leads with 25 of the 64 records in scope in this dataset, well ahead of the rest of the field; by fifth place the count drops to 3 records. The top five assignees combined account for 85.9% of all records, meaning most of the documented claim space sits with a small group. That leader's portfolio centres on protein hydrolysate methods, the same technical area as the most-cited record in this dataset.
Filing peaked in 2020 at 15 records and then declined; the comparison from 2021 to 2024, the most recent period that can be treated as complete, shows a 33% drop. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they should not yet be read as continuing the decline. The honest read is a real pullback from a 2020 peak, with the very latest trend still unresolved.
The dataset spans eight IPC subclasses, led by A23J (proteins and food peptides) at 43.8% of the 64 records, A23L (foods and beverages) at 39.1%, and A23K (animal feed) at 35.9%. Fertiliser-related C05F and biocide-related A01N each appear in 18.8% of records, while A01K (animal husbandry, covering rearing methods) is the smallest tracked class at 17.2%. Because a single record can carry multiple IPC codes, these shares add up to more than 100%.
Rearing climate-control hardware and frass fertiliser formulation sit in the smaller IPC classes tracked here (A01K at 17.2% and C05F at 18.8%), well below the protein and feed classes that dominate filing. Degutting and microbial-quality processing, plus lipid-fraction co-product streams, are represented in the most-cited records but have not generated the same filing density as core hydrolysate claims. These are reasonable areas to investigate for a first-mover filing, though a full freedom-to-operate search against the named IPC classes is the necessary next step.
The United States leads receiving offices with 13 filings, followed closely by WIPO PCT applications at 12 and the European Patent Office at 11. Canada, India and the Philippines each show smaller but notable counts of 6, 5 and 5 respectively, indicating filing activity extends beyond the traditional US-Europe axis into markets with active insect-farming regulatory programmes. This spread reflects the international and regulatory nature of feed and food-safety approval for insect-derived products.
