Patent Landscape · Bioenergy & Low-Carbon FuelsBiodiesel and renewable diesel patents: who holds the fuel-composition claims and where the field is still open
- 55.8% of all 2,420 records sit with just five assignees, and the leader alone accounts for 776 records — this field is unusually concentrated at the top.
- C10L fuel-composition claims cover 69.5% of records while adjacent branches like C01B, C10M and F28D each sit under 5%, marking where claim density thins out fast.
- Filings eased 15% from 2021 to 2024 (169 to 144) after peaking at 264 in 2023 — a maturing wave, not a collapsing one, given publication lag.

Leading Jurisdiction
Filing growth compares 2021 (169 records) with 2024 (144) — 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 2,420 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape maps 2,420 published patent records filed between 2015 and 2026 that combine biofuel, biodiesel or renewable diesel feedstock claims with fuel composition, product upgrading, thermal conversion or fuel-quality claims. The scope captures the two ends of the value chain that most often get litigated separately: how the feedstock is converted, and what the finished fuel is claimed to contain or do. Patent families, not raw document counts, are the fairer unit here because they neutralise continuation filings and multi-jurisdiction duplicates.
Filing activity peaked in 2023 and the leaderboard is dominated by a handful of specialty-fuel and major-oil assignees whose portfolios span both feedstock conversion and additive chemistry. Publication lags filing by roughly 18 months, so 2025 and 2026 figures will fill in as they clear examination — they should not be read as a drop-off yet.

The Data
Filing trends and technology composition
Two views of the same 2,420-record corpus: filing activity by year, and the IPC subclasses those records claim into. Because a record can carry several classes, the composition shares add up to more than 100%.
Filing trend, 2017-2026
Filings rose from 139 in 2017 to a peak of 264 in 2023, then eased to 144 by 2024 — a 15% decline over the 2021-2024 span. The 2025-2026 tail is still incomplete due to publication lag and should not be read as a slowdown yet.
Technology composition by IPC subclass
C10L (fuels & firelighters) covers 69.5% of records, more than three times the next largest class, C10G (hydrocarbon oils & refining) at 21.7%. Everything past C07C's 9.5% sits under 5% of records, which is where claim space thins out.
Shares are the percentage of the 2,420 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the numbers mean for strategy
Three figures worth acting on: how concentrated ownership is, where the claim density sits, and what the recent filing trend actually supports.
Concentration
55.8% of 2,420 records
held by top 5 assignees
Ownership is concentrated at the top
The leading assignee alone holds 776 records, and the top five combined account for 55.8% of all 2,420 records in scope. Freedom-to-operate work in this space has to start with those portfolios, not a broad novelty search.
Source: assignee ranking, 100 companies
Claim density
69.5% in C10L
vs. under 5% past C07C
Fuel-composition claims dominate the map
C10L (fuels & firelighters) covers 69.5% of records and C10G (refining) 21.7%, but every subclass past C07C's 9.5% — including C01B, C10M, B01D and F28D — sits below 5%. That gap is where process-side and separation claims are thinner on the ground.

A cooling wave, not a retreat
Filings fell from 169 in 2021 to 144 in 2024 after peaking at 264 in 2023. That is a real easing over a complete three-year window, but 2025-2026 figures are still incomplete due to publication lag and will move upward as they clear.

Players
Who holds the claim space
The ranking covers 100 companies scored by record count. A small group of specialty-fuel and major-oil assignees hold the bulk of the filings, with a long tail of single- and few-record entrants behind them.
Leader
776 records
single largest assignee
One assignee sets the pace
The top-ranked assignee holds 776 records, well ahead of fifth place at 106 and tenth place at 34 — a steep drop that marks this as a leader-plus-field market rather than an even spread.

Top 10
66.9% of 2,420 records
held by ten assignees
Ten firms cover two-thirds of the field
The top ten assignees combined account for 1,618 records, or 66.9% of all 2,420 records in scope, leaving the remaining 90 ranked companies to split the rest.

Momentum

across leading assignees
Recent-year filings are down across the leaderboard
Every leading assignee tracked shows flat or declining latest-year output, from a 25% year-over-year drop at the largest filer to several assignees at zero for the latest year. Given publication lag, this likely overstates the slowdown rather than signalling withdrawal.

What's Next
Where to take this
The dataset points to three practical next steps for teams working in biodiesel and renewable diesel.
Map freedom-to-operate against the top five
With 55.8% of records held by five assignees, any new fuel-composition or upgrading claim should be checked against those portfolios first rather than the full field.
Explore assignee portfolios in EurekaTest claims in the under-5% classes
Separation, lubricant-grade blending and heat-exchange integration all sit under 5% of records — a first claim drafted carefully there faces less prior art than another C10L fuel-composition filing.
Run a white-space search in EurekaRe-check momentum once 2025-2026 data clears
Recent-year declines across leading assignees are likely inflated by publication lag; revisit the trend once those years are more complete before concluding the field is cooling.

FAQ
Common questions on biodiesel and renewable diesel patents
One assignee leads the field with 776 of the 2,420 records in scope, far ahead of the fifth-ranked company at 106 and the tenth at 34. The top five assignees combined hold 55.8% of all records, and the top ten hold 66.9%. That gap between the leader and the rest means most freedom-to-operate risk sits with a small number of specialty-fuel and major-oil portfolios rather than being spread evenly across the field.
Filings rose from 139 in 2017 to a peak of 264 in 2023, then eased to 144 by 2024, a 15% decline over the complete 2021-2024 window. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so the most recent years understate actual activity. Read the 2023 peak and the subsequent easing as a maturing filing wave rather than a sharp retreat.
Fuel-composition claims under IPC class C10L cover 69.5% of the 2,420 records, making it by far the densest area. Hydrocarbon oils and refining (C10G) follows at 21.7%, and acyclic/carbocyclic compound claims (C07C) at 9.5%. Everything beyond that — including inorganic feedstock chemistry, lubricants, separation processes and heat-exchange apparatus — sits under 5% of records each, which is where claim space is comparatively open.
US20220049174A1, assigned to Neste, claims a diesel fuel composition that combines a renewable diesel component with oxymethylene ethers (OME3-5) to reduce particle emissions, plus a method for producing that blend. It does not claim renewable diesel itself, but the specific additive combination and its emissions-reduction use. Anyone blending OME-type additives into a renewable diesel base for emissions performance should review this filing's claim scope before finalising a formulation.
The clearest white space sits in the IPC classes that trail well behind the dominant fuel-composition claims: separation processes, lubricant-grade blending, heat-exchange integration for thermal conversion, and enzymatic upgrading pathways each cover under 5% of the 2,420 records. These are not unclaimed, but they are far less crowded than C10L fuel-composition space, making them a more tractable place to draft a first claim than competing directly with the concentrated leaders.
