Hydrogen Peroxide Room Decontamination Patents: Leaders & Trends 2026
Hydrogen Peroxide Room Decontamination Patents: Who Leads and Where Filing Has Cooled
Concentrated at the top. The top 5 assignees hold 445 of 691 records in scope (64.4%), and the top 10 hold 77.9% — a small group controls most of the documented claim space. Annual filings rose to a peak of 60 in 2020, then fell from 49 in 2021 to 15 in 2024 — a 69% drop over that span. The leader's own recent-year filings echo this: down 50% year-over-year in the latest tracked period. Treat 2025-2026 counts as provisional given publication lag.

Frequently asked questions
Who holds the most patents in hydrogen peroxide room decontamination?
One assignee leads the ranked list with 159 of the 691 records in scope, well ahead of the fifth-place holder at 35 and tenth place at 16. The top 5 assignees combined account for 64.4% of all records, and the top 10 account for 77.9%. This means a competitive or freedom-to-operate review should prioritise the leading few names before spreading attention across the full 100-company ranking.
Is patent filing activity in this space growing or shrinking?
Filing peaked in 2020 at 60 records and then declined, falling from 49 in 2021 to 15 in 2024 — a 69% drop over that three-year span. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 counts in any trend chart are still incomplete and should not yet be read as continuing the decline. Based on the complete years through 2024, however, filing momentum has clearly cooled from its 2020 high.
What does US20080206801A1 actually cover?
US20080206801A1, assigned to American Sterilizer Company, claims a biological indicator design: a carrier with a recess that restricts movement of an inoculum, where the inoculum’s suspension medium includes a wetting agent to reduce surface tension so it plates out evenly rather than stacking. The microorganisms are prepared by removing extraneous material and sonicating to break up agglomerations before deposit. Anyone designing a biological indicator carrier or inoculum-preparation process for vaporous decontamination validation should check this filing’s specific claim language on the recess geometry and wetting-agent formulation.
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 Hydrogen Peroxide Room Decontamination covering 2015–2026, data cut-off 2026-07-31.
