Integral PWR SMR Patents: Who Leads, Where the Gaps Are 2026
Integral Pressurized Water SMR Design Patents: Who Holds the Core Claims
77.9% of all 77 records sit with just five assignees, while the remaining eighteen ranked filers split the rest — a concentrated field with a long tail. Annual filings ran from 11 in 2017 to a peak of 12 in 2022, then declined toward 1 in 2026 — a partial year that will fill in as later publications clear the pipeline. Read the recent downturn cautiously rather than as a settled retreat from the space.

Common questions on this landscape
Who holds the most patents on integral pressurized water SMR design?
One assignee leads with 17 of the 77 records in this dataset, well ahead of the fifth-ranked filer at 6. The top five assignees combined hold 60 records, which is 77.9% of all 77 records in scope, so the field is concentrated rather than evenly split. The remaining eighteen ranked companies, universities and individual inventors account for a long tail of smaller filings.
Is marine or offshore deployment a significant part of SMR patenting?
Within this scope, yes: 27.3% of the 77 records carry a ships-and-marine-vessels classification (B63B), and a smaller set also touch naval vessel classes (B63G, 7.8%). That suggests offshore and shipyard-delivered reactor platforms are a genuine, separately-claimed design track rather than an incidental overlap with reactor patents.
Has patent filing for integral PWR SMR designs slowed down?
Filings rose from 11 in 2017 to a peak of 12 in 2022, then declined toward 1 in the partial 2026 year. Because publication typically lags filing by around eighteen months, the most recent one to two years understate actual activity, so it is too early to call this a definitive slowdown rather than a reporting gap.
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 Integral Pressurized Water SMR Design 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.
