Retrieval Augmented Generation Pipeline Patents: Filing Trends and Claim Concentration
Filings jumped from zero in 2017 to a peak of 261 in 2025, then a partial 2026 count of 35 that understates true filing activity given the roughly 18-month publication lag. Filings were effectively absent through 2017 and climbed to a peak of 261 records in 2025. The 2026 figure of 35 is a partial-year count and should not be read as a slowdown — it reflects records not yet published rather than filings not yet made.

Common questions on RAG pipeline patents
How many patents exist for retrieval augmented generation pipelines?
This landscape identifies 489 published records matching claim language on RAG pipeline mechanics such as document chunking, chunk overlap, prompt construction, context window handling, relevance ranking and citation attribution, across coverage from 2015 through mid-2026. That figure reflects the specific search criteria used, not every AI-related filing that mentions retrieval — records without both a pipeline term and a technical control term are excluded. Because publication lags filing by roughly 18 months, the true number of filings made in 2025 and 2026 is understated in any current count.
Who are the leading patent filers in RAG pipeline technology?
The ranked assignee list contains 100 companies, with the leader holding 26 of the 489 records in scope. The top 5 assignees combined account for 19.4% of all records and the top 10 combined reach 31.7%, which is meaningful concentration but leaves roughly two-thirds of the field outside the ranked leaders. Recent-year momentum data shows even several ranked assignees dropping to zero or one filing, indicating the leadership picture is still moving rather than settled.
What technology areas do RAG pipeline patents cover?
The dominant IPC class is G06F (electric digital data processing), appearing in 73.8% of the 489 records, followed by G06N (AI-model computing) at 32.3%. Smaller but distinct clusters appear in G06Q (business/admin processing), H04L (digital transmission), G10L (speech/audio), G16H (healthcare informatics), G16B (bioinformatics) and G06V (image/video recognition), each under 8.2% of records. Because a single record can carry multiple IPC codes, these shares add up to more than 100% of the record total.
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.
