Module cleaning and soiling management patents: who is filing, and where the field is still open
39.4% concentration at the top. The five leading assignees combined account for 327 of 829 records in scope — a concentrated core with a long tail of single- and few-filing entrants behind it. Annual filings rose from 18 in 2017 to a peak of 54 in 2022, before settling to a still-elevated level; growth from 20 filings in 2021 to 42 in 2024 (+110%) marks the clearest sustained expansion in the window. The 2025-2026 figures are partial and will rise as later publications land.

Common questions about this landscape
How many patents cover module cleaning and soiling management?
This dataset contains 829 published patent records filed between 2015 and 2026 that match cleaning-mechanism terms combined with soiling-management engineering constraints such as dust adhesion force, brush wear, and cleaning-frequency modelling. Because publication lags filing by roughly 18 months, the true count for 2025 and 2026 will be higher once those records finish publishing. The figure should be read as records in scope for this specific search, not as a total count of every cleaning-related patent ever filed.
Who are the leading patent holders in module cleaning and soiling management?
Filing is concentrated at the top: the five leading assignees combined hold 327 of 829 records, 39.4% of the field, and the single leading assignee holds 132 records on its own. Beyond the top 10, which together hold 49.3% of records, filing activity spreads across a long tail of entities with only one or a few records each. This pattern suggests a genuine leader plus many smaller, harder-to-track filers rather than a handful of comparably sized competitors.
Is patent filing in this space growing or slowing down?
Filing activity grew substantially in recent years: from 20 filings in 2021 to 42 in 2024, a +110% increase over that three-year span, with a peak of 54 filings in 2022. The 2025 and 2026 figures appear lower only because publication lags actual filing by roughly 18 months, so those years are still filling in. Based on the complete years available, the trend through 2024 is one of sustained growth, not decline.
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 Module Cleaning and Soiling 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.
