Overview
What this landscape covers
Acoustic metamaterial panels use engineered sub-wavelength unit cells — meta cells — to absorb, block or redirect sound in ways ordinary layered materials cannot. This landscape covers 36 patent records filed between 2015 and the 2026 data cut-off, spanning core acoustic absorption structures, HVAC noise-control integration, aerospace structural panels and a scattering of adjacent applications in vibration damping, antenna design and implants.
Filing is concentrated among a small set of assignees but not closed off: the top 5 hold 61.1% of records and the top 10 hold 88.9%, leaving room below a long tail of single-filing entrants. The technology itself skews heavily toward core acoustic absorption claims, with HVAC integration the only other branch carrying meaningful depth.

Filing Data
Filing trend and technology composition
The 36 records in scope span 2015 through the 2026 cut-off, with publication lag meaning the most recent two years are still filling in.
Filing activity peaked in 2023
Filings rose from 2 in 2017 to a peak of 10 in 2023. Across the most recent complete three-year window, 2021 to 2024, filings held flat at 4 to 4 — 0% growth — so the field is not accelerating on the evidence available, though 2025 onward will revise upward as later publications land.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Acoustics dominates the class mix
G10K (acoustics and sound generation) appears in 77.8% of the 36 records, far ahead of F24F (air conditioning and ventilation) at 22.2%. Smaller shares in B32B, B64C, B64D, F16F, H01Q and A61F show panels being claimed alongside laminate construction, aerospace structure, vibration damping, antenna integration and implants — each a minority branch, not a second core.
Shares are the percentage of the 36 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

A representative filing: the hybrid meta cell approach
Representative Record · WO2023167649A1
META cells and an acoustic metamaterial panel comprising at least one acoustic META cell
METADYNA MÜHENDİSLİK SANAYİ VE TİCARET ANONİM ŞİRKETİ
The invention is related to the development of meta cells, which can show both passive material and meta properties (i.e., hybrid properties) and multifunctional acoustic metamaterial panel comprising at least one hybrid meta cell in order to decrease the transmission of sound waves and/or attenuate sound waves in a desired narrow or wide frequency band.Filed by Metadyna Mühendislik, 2023-09-07. The hybrid passive-plus-meta property framing is the claim's distinguishing feature against single-property absorptive or resonant panel designs.

What the filing pattern signals
Three findings stand out once the 36 records are broken down by assignee, class and time — none of them visible from a simple keyword count.
Concentration
61.1%
of 36 records held by top 5 assignees
Filing is concentrated but not closed
The top 5 assignees hold 61.1% of the 36 records in scope and the top 10 hold 88.9%, leaving a real tail below them across the 16 ranked companies. That is concentrated enough to signal established players, but not so concentrated that a well-targeted filing has no room.
Based on the assignee ranking of 16 companies.
Growth
0%
filing change, 2021 to 2024
Flat, not declining
Filings held at 4 in 2021 and 4 in 2024, the last window unaffected by publication lag. The 2023 peak of 10 sits inside that window, so year-to-year volume is uneven even where the three-year comparison reads flat.
2025 and later data will revise upward as publication catches up to filing.
Class mix
77.8%
of records classed under G10K acoustics
One dominant class, several thin adjacents
G10K covers more than three-quarters of records; the next largest class, F24F for HVAC integration, covers 22.2%. Everything else — laminates, aerospace structure, vibration damping, antennas, implants — sits at 8.3% or below, each a narrow adjacent rather than a second core.
Classes overlap, so shares sum to more than 100% of the 36 records.
Citations
30 cites
on the single most-cited record
Influence sits with the oldest filings
US8579073B2, the most-cited record in this set, anchors the citation graph well ahead of more recent filings such as US20250182729A1. That gap is expected in a searched corpus — older claims accumulate citations simply by being on file longer — and should be read as a mark of influence, not current commercial weight.
Citation counts favour earlier filing dates by construction.

Next Steps
Where to take this analysis
The dataset points to a concentrated core and a genuine tail of white space. The next step is testing a specific claim or design against that pattern directly.

FAQ
Frequently asked questions
The assignee ranking covers 16 companies across the 36 records in scope, with the leader holding 8 records. The top 5 assignees combined account for 61.1% of all 36 records, and the top 10 account for 88.9%, so filing is concentrated among a small group with a long tail of single-digit filers below them. Boeing, Trane, and specialised firms such as Metadyna sit among the named assignees, alongside academic filers like the Hong Kong University of Science and Technology and Indian Institute of Technology Roorkee.
Based on the classification spread, the primary use is sound absorption and attenuation (G10K, 77.8% of records), with a secondary cluster in HVAC noise control (F24F, 22.2% of records). Smaller filing shares also cover aerospace structural panels, vibration damping and layered laminate construction, indicating the panel format is being adapted into ducting, airframes and general structural noise control rather than staying a single-purpose product.
Filing activity rose from 2 records in 2017 to a peak of 10 in 2023, but across the most recent complete three-year comparison — 2021 to 2024 — filings were flat at 4 to 4, a 0% change. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and will revise upward, so this flat reading should not yet be taken as a slowdown.
WO2023167649A1, filed by Metadyna Mühendislik in 2023, claims a hybrid meta cell that combines passive material properties with metamaterial (meta) properties in the same unit, assembled into a panel to reduce or attenuate sound transmission across a chosen frequency band. It is a foundational filing for the hybrid meta-cell approach specifically, rather than for acoustic metamaterial panels generally, and later filings such as US20250182729A1 already cite it and build on the same concept.
The core acoustic-absorption class (G10K) is the most heavily claimed at 77.8% of the 36 records and carries the highest-cited prior art, including US8579073B2 at 30 citations. Lower-density branches such as implant integration (A61F, 2.8%), antenna-combined metasurfaces (H01Q, 5.6%) and vibration-damping combinations (F16F, 5.6%) show far less claim density in this dataset, making them a more open starting point for a first filing, provided the underlying acoustic mechanism is genuinely novel rather than a relabelled absorptive panel.
