LED Spectrum Recipes for Plant Growth Patents: Top Companies 2026
- One filer holds 191 of 345 records in scope — the top 5 assignees together account for 75.9% of all filings, leaving a long tail of 42 smaller entrants.
- Filings peaked in 2020 at 65 and have since declined with 2021's 50 filings falling to 24 by 2024, a 52% drop over that span — the last window recent enough to read as complete.
- A01G and H05B dominate the classification mix at 64.3% and 30.4% of records respectively, while measurement and data-processing classes stay under 8%, pointing to thin coverage in sensing-driven control.
Filing growth compares 2021 (50 records) with 2024 (24) — 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 345 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
LED spectrum recipe patents cover the control logic and hardware behind tuning red, blue and far-red ratios, photoperiod and photosynthetic photon flux to steer plant morphology and secondary metabolite output. The search spans 345 records filed or published between 2015 and mid-2026, drawn from horticultural lighting claims that reference light recipes, red-blue ratios, far-red addition, photoperiod control or morphology and metabolite response. Because publication lags filing by roughly 18 months, the most recent one to two years in any trend chart will always look thinner than they eventually turn out to be.
Patent families, not raw document counts, are the fairer unit for judging how crowded a claim space really is, since families strip out the inflation from continuations and multi-jurisdiction refiling. This landscape treats each of the 345 records as a family-level entry for that reason.

Filing trends and classification mix
Two views matter here: how filing volume has moved year over year, and how records distribute across IPC subclasses. Both are read against the full 345-record scope, not against any filtered subset.
Filing trend, 2017–2026
Filings rose from 20 in 2017 to a peak of 65 in 2020, then eased to 50 in 2021 and 24 by 2024 — a 52% decline over that three-year window. Readings for 2025 and 2026 are still filling in and should not be read as a continued fall.
IPC subclass composition
A01G (horticulture and forestry) appears in 64.3% of the 345 records and H05B (electric heating and lighting circuits) in 30.4%, confirming that most claims sit at the intersection of growing method and lighting circuitry rather than pure optics. F21V lighting components reach 18.8%, while G01J light measurement and G06F data processing each stay at or under 7.0% and 4.1% — a record can carry multiple classes, so these figures add to more than 100%.
Shares are the percentage of the 345 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method and apparatus for horticultural lighting to better simulate the sun
A method and apparatus for a horticultural light system for use in a greenhouse where aspects of ambient light in the greenhouse are measured and compared against a prescribed light recipe. A light controller commands a light fixture contained within the greenhouse to augment the ambient light in response to the comparison. Photosynthetic photon flux, light intensity, color temperature and color spectrum among other aspects of light generated by the light fixture are altered by the controller to fill in deficiencies of the ambient light as compared to the prescribed light recipe.Filed by Scynce LED, published 2019-11-28 — anchors the closed-loop sensing-plus-augmentation approach to light recipe delivery.

The numbers point to a field with one very large filer, a fast tail-off after the top ranks, and classification density concentrated in a narrow set of subclasses.
Filing is heavily concentrated at the top
The leading assignee alone accounts for 191 of the 345 records in scope. Combined with the next four, the top 5 hold 75.9% of all filings, and the top 10 extend that to 89.3%. That leaves roughly a tenth of the field split across 37 further ranked companies.
Peak filing has passed, but the read is incomplete
Volume peaked in 2020 at 65 filings and pulled back through 2021-2024, a decline the data supports directly. Years beyond 2024 are still filling in under the usual publication lag, so this should be read as a plateau after a filing wave rather than a verdict on future interest.
Claims cluster on horticulture method, not pure optics
A01G and H05B together dominate the classification mix, meaning most filings frame the invention as a growing method paired with lighting circuitry. Measurement (G01J) and data processing (G06F) subclasses sit far lower, at 7.0% and 4.1%, suggesting sensing-and-feedback claims are comparatively sparse.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to led spectrum recipes for plant growth, with the prior art for and against each one.
The assignee landscape
Forty-seven companies appear in the ranked list this dataset returns — not a top-50 or top-100 cut, but the entire ranked set. One filer dominates by volume; most of the rest hold single-digit counts.
One filer sets the pace by a wide margin
The leading assignee's count of 191 dwarfs the fifth-place holder's 15 and the tenth-place holder's 8, a drop-off steep enough that the rest of the field reads as a long tail rather than a cluster of comparable competitors.
Momentum has cooled across the top ranks
Several of the most prolific historical filers show zero filings in the latest year, with year-over-year drops of -100% recorded for multiple leaders. This tracks with the broader 2021-2024 pullback rather than signalling exit from the field, given the publication lag on recent filings.
Co-filing is limited and tightly clustered
Only 10 co-assignee pairs appear across the dataset, and the strongest pairing reaches 6 shared filings. Co-filing here looks more like corporate-entity linkage (parent and subsidiary naming variants) than cross-company research partnership.

One assignee leads the field decisively, holding 191 of the 345 records in scope, far ahead of the fifth-ranked holder's 15 and the tenth-ranked holder's 8. The top 5 assignees combined account for 75.9% of all filings, and the top 10 reach 89.3%. The remaining 37 companies in the 47-company ranked list each hold small counts, forming a long tail rather than a set of comparable mid-tier competitors.
Filing volume peaked in 2020 at 65 records and declined through 2021 (50) to 2024 (24), a drop of 52% over that span. That said, 2025 and 2026 figures are not yet complete because publication typically lags filing by around 18 months, so recent years understate true activity. The honest read is a plateau or pullback after an earlier filing wave, not a confirmed downward trend into the present.
The dominant classes are A01G (horticulture and forestry), present in 64.3% of the 345 records, and H05B (electric heating and lighting circuits) at 30.4%. F21V (lighting device components) appears in 18.8% of records. Measurement-related class G01J and data-processing class G06F are comparatively rare, at 7.0% and 4.1% respectively, indicating that sensing and software-driven control are less densely claimed than the core lighting and horticulture method space.
This filing, held by Scynce LED and published in November 2019, covers a closed-loop method where ambient greenhouse light is measured, compared against a prescribed light recipe, and a controller adjusts a fixture's photosynthetic photon flux, intensity, colour temperature and spectrum to close the gap. It sits among the field's most-cited prior art alongside other high-citation records in the 300-plus citation range. Anyone building a sensing-and-augmentation light recipe controller should check their claim scope against this filing's specific measurement-comparison-adjustment sequence before finalising claim language.
Classification data points to thinner coverage in sensing and data-processing-driven control: G01J (light measurement) and G06F (data processing) each sit under 8% of the 345 records, well below the 64.3% and 30.4% held by the core horticulture and lighting-circuit classes. Sub-areas like closed-loop spectral feedback, far-red-triggered shade-avoidance tuning and multi-sensor photoperiod scheduling show comparatively few dedicated filings. That gap suggests room for a first claim built around sensor-driven adaptive recipe adjustment rather than fixed spectrum ratios.
