Advanced Wound Dressings and Hydrogels: Patents Shaping Moisture Balance and Exudate Management
38.1% of filings sit with the top 5. of the 21 records in scope, so a small cluster of assignees holds the largest single share but well under half — leaving substantial room for new entrants. Filings rose from zero in 2017 to a peak of 7 in 2025, though 2021 to 2024 shows a -100% swing on a small base — a reminder that early counts move sharply on low volumes rather than signalling a durable slowdown. 2026 figures are partial and will revise upward as publication catches up with filing.

Frequently asked questions
Who are the leading patent holders in advanced wound dressings and hydrogels?
Among the 34 companies in the assignee ranking, the leading assignee holds 3 of the 21 records in scope, with the fifth- and tenth-ranked assignees each holding just 1. The top 5 assignees combined account for 38.1% of records and the top 10 for 61.9%, meaning leadership exists but no single filer controls the field. A large share of activity comes from academic and research institutions rather than established medical device manufacturers.
What technology areas dominate advanced wound dressing patents?
Sterilising and disinfecting technology under IPC class A61L appears in 85.7% of the 21 records, making it by far the most heavily claimed area. Medicinal preparations (A61K) and implants or prostheses (A61F) follow at 42.9% and 33.3% respectively. Polysaccharide-based chemistry and vinyl-addition polymer approaches each appear in under 10% of records, indicating comparatively less-crowded claim space there.
Is filing activity in this field growing or slowing down?
Filings rose from zero in 2017 to a peak of 7 in 2025, but a -100% swing from 2021 to 2024 reflects a small base rather than a genuine collapse in interest. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and will revise upward. The honest read is that recent-year trend data cannot yet support a firm growing-or-slowing conclusion.
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 Advanced Wound Dressings and Hydrogels 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.
