Ship energy efficiency management patents: who is filing, and what is still open
Concentrated but not closed. the ranked leaders' top 5 account for 63.2% of all 19 records in scope, yet the top 10 combined reach 94.7% — most of the field's activity sits with a small group of assignees. Filings moved from 0 in 2017 to a peak of 7 in 2023, with 2 recorded so far in 2026. Growth rate is not stated here because fewer than four complete years remain once publication lag is accounted for — treat the 2025-2026 tail as understated rather than as a real slowdown.

Common questions
Who holds the most patents in ship energy efficiency management?
The ranking covers 11 companies, and the top-ranked assignee holds 3 of the 19 records in scope, with fifth place holding 2 and tenth place holding 1. That is a narrow gap between the leader and the rest of the ranked field, so no single organisation has a dominant, defensible lead yet. Anyone assessing this space should look at the top 5 together (63.2% of all records) rather than treating the single leader as a gatekeeper.
Is ship energy efficiency patent filing growing or slowing down?
Filing rose from 0 in 2017 to a peak of 7 in 2023, and 2 records have already published in the partial 2026 year. A precise growth rate is not calculable here because fewer than four complete years remain once the roughly 18-month publication lag is taken into account, so the apparent drop after 2023 should be read as a lag artefact rather than a confirmed slowdown. Anyone tracking this field should revisit the trend after the next publication cycle before drawing conclusions.
What technology areas dominate ship energy efficiency patents?
B63B (ships and marine vessels) and G06Q (business, commerce and admin data processing) are the two largest classes, covering 47.4% and 42.1% of the 19 records respectively. G06F and G06N, both tied to digital processing and AI models, each cover 26.3%, while G05D (control of non-electric variables) covers only 15.8%. This mix shows that a large share of current filing activity treats fuel-consumption and CII compliance as data-processing problems rather than purely mechanical or control-engineering ones.
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 Ship Energy Efficiency Management 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.
