Audio and Video Watermarking Patents: Top Companies & Trends 2026
Audio and Video Watermarking Patents: Who Holds the Core Claims
46.8% concentration. The five leading assignees hold 230 of 491 records in scope — filings are concentrated at the top with a long tail below tenth place. Annual filings rose to a peak of 22 records in 2021, then eased to 18 by 2024 — an 18% decline over that three-year window. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continued drop.

Common questions on watermarking patents
Who holds the most patents in audio and video watermarking?
The assignee ranking for this dataset covers 100 companies across 491 records, and the leading assignee alone holds 77 of them. The top five combined account for 230 records, or 46.8% of all records in scope, while the gap down to tenth place (10 records) shows a long tail of smaller filers rather than an even spread. This concentration means a freedom-to-operate review should prioritise the top few portfolios first rather than treating the field as fragmented.
Is video or audio watermarking more heavily patented?
By IPC classification, video-side pictorial communication (H04N) appears on 48.9% of the 491 records, ahead of speech and audio analysis/synthesis (G10L) at 42.2%. Because a single filing can carry both classifications, this does not mean audio watermarking is neglected — many filings claim techniques that apply to both media types. It does suggest that new video-only embedding claims face denser prior art than audio-only ones.
Has filing activity in this field been growing or slowing?
Filing activity peaked at 22 records in 2021 and had eased to 18 records by 2024, an 18% decline over that three-year window. Figures for 2025 and 2026 are still incomplete because patent publication typically lags actual filing by around 18 months, so those most recent years should not yet be read as continued decline. A clearer read on the current trajectory will only be possible once those years finish publishing.
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 Audio and Video Watermarking 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.
