LoRA & Parameter-Efficient Tuning Patents: Leaders & Trends 2026
Low-Rank Adaptation and Parameter-Efficient Tuning Patents
+850% filing growth from 2021 to 2024 the last complete filing years in scope, before publication lag understates 2025-2026. Filings sat at zero in 2017 and stayed negligible until 2021, when the count reached 2. From there the field grew sharply to 19 filings in 2024 — an increase of 850% over that three-year span — before peaking so far at 26 in 2025. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and should not be read as a plateau or decline.

Common questions about this patent landscape
How many patents exist for low-rank adaptation and parameter-efficient tuning?
This dataset contains 90 published patent records in scope, spanning the period from 2015 through the 2026-07-31 cut-off. Filing activity in this specific technical intersection was negligible before 2021 and then grew sharply, reaching 19 filings in 2024 and a further 26 in 2025 (though 2025 figures are still incomplete due to publication lag). Because a single record can carry multiple technology classifications, class-level counts in the composition breakdown add up to more than the 90-record total.
Who are the leading patent filers in low-rank adaptation?
The ranking covers 48 companies, not a fixed top-50 or top-100 cut, and the leader holds 11 of the 90 records in scope. Concentration drops off quickly: the top 5 assignees combined hold 40.0% of all records, and the top 10 combined hold 60.0%, leaving a long tail of filers with only one or two records each. This shape suggests the field is still open to new entrants rather than locked up by a small number of incumbents.
Is the low-rank adaptation patent field growing or slowing down?
It is growing, and growing quickly. Filings rose from 2 in 2021 to 19 in 2024, an increase of 850% over that three-year span, with a further peak of 26 filings recorded in 2025. Because patent publication typically lags filing by around 18 months, the most recent one to two years in any such dataset will always look artificially low, so the apparent 2025-2026 figures should not be read as a slowdown.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Low Rank Adaptation and Parameter Efficient Tuning covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
