Patent Landscape · Acoustics & Noise ControlVibration Damping and Isolation Patents: Where Filing Activity Sits Today
- Filing has cooled from its 2017 peak. 143 filings that year against 20 in the latest (partial) year, with the 2022 midpoint of 70 confirming a declining trend rather than a temporary dip.
- Claim space is concentrated in one IPC subclass. F16F (springs & vibration dampers) covers 4,043 of 4,066 records, while adjacent classes like G10K (acoustics) and E04B (building structures) carry only a few hundred each.
- One inventor-assignee pair dominates co-filing. The Kochetov Oleg Savelevich / KOCHETOV OLEG SAVELEVICH pairing appears 168 times, far ahead of the next strongest pair at 18.

Leading Jurisdiction
Filing growth compares 2021 (93 records) with 2024 (75) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 4,066 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This dataset tracks patent families filed against damping materials, tuned mass dampers, and vibration isolation systems, indexed under F16F15, F16F1 and F16F9 and cross-referenced against loss factor, constrained-layer, transmissibility and resonance terminology in titles and claims. The corpus spans 2015 through mid-2026, drawing largely on mechanical damping hardware rather than pure materials science, though polymer composition classes appear as a secondary layer.
Publication lags filing by roughly 18 months, so the most recent year's count understates real filing activity. The 2017 peak and the subsequent decline through 2022 and beyond are the more reliable signal, and they point to a field where claim space filled early and has not reopened.

The Numbers
Filing trends and technology composition
Four core figures orient the rest of the analysis: total volume, where filings peaked, which IPC subclasses carry the claim density, and where applicants have chosen to file.
A field past its filing peak
Filings rose to 143 in 2017 and have declined since, with the 2022 midpoint at 70 confirming the drop is structural rather than a single-year anomaly. The most recent year is partial and will revise upward, but not enough to reverse the trend.
Almost all activity sits in one mechanical subclass
F16F accounts for 4,043 of 4,066 records — essentially the entire dataset — while B32B (laminates), B60K (vehicle propulsion) and C08L (polymer compositions) appear as secondary classifications on a minority of those same families, indicating most innovation is claimed as a mechanical assembly first.
Shares are the percentage of the 4,066 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the data means for filing decisions
Three patterns matter more than the raw counts: where the field's claim density actually sits, how citation influence skews toward older art, and how co-filing concentrates around a small number of relationships.
Claim Density
4,043 / 4,066
records classed under F16F
Mechanical hardware, not materials, carries the claims
Nearly every record in this corpus is classified under F16F, the springs-and-vibration-dampers subclass. Secondary classes like B32B and C08L appear on a subset of those same families rather than as independent filing streams, meaning damping material composition is usually claimed as a component of a mechanical assembly rather than standalone.
Implication: assembly-level claims are the crowded ground; material-only claims are comparatively rare.
Filing Momentum
143 → 20
annual filings, 2017 to latest year
The field has been contracting since its 2017 peak
Filing volume fell from a peak of 143 in 2017 to 20 in the most recent (partial) year, with the 2022 midpoint of 70 confirming a sustained decline rather than a short-term dip. Even allowing for publication lag understating the latest year, the multi-year trajectory is downward.
Implication: new entrants are filing into a shrinking pipeline, not a growing one.
Citation Influence
248 citations
shared top citation count
The most-cited prior art predates the current filing window
The two most-cited records in the corpus, both centred on torsional and vehicle vibration damping, each carry 248 citations. High citation counts here reflect age and foundational position within the searched corpus more than ongoing commercial weight.
Implication: treat these as the claim territory later filings had to design around, not as active competitive threats.
Co-Filing Concentration
168 vs 18
strongest vs. second-strongest co-assignee pair
One inventor relationship dominates joint filings
Among just 10 recorded co-assignee pairs, the Kochetov Oleg Savelevich / KOCHETOV OLEG SAVELEVICH pairing appears 168 times — far ahead of the next pairing at 18. Corporate co-filing, by contrast, is thin and mostly limited to automotive supplier relationships.
Implication: collaborative filing is rare in this field; most assignees file independently.

Players
Who is filing, and where the activity has gone quiet
Recent-year momentum tells a different story from cumulative volume: several of the historically largest filers show no activity in the latest recorded year, consistent with the field-wide decline rather than any single company exiting.
Automotive Suppliers
0 in latest year
momentum for Sumitomo Riko Company Limited
Historic volume leaders have gone quiet
Sumitomo Riko Company Limited (Sumitomo Riko) shows a -100% year-over-year change, with zero filings in the latest recorded year. The same pattern holds for Bridgestone Corporation, Toyota Motor Corporation and Nissan Motor Co., Ltd. — all historically active, all showing zero in the most recent year.
Read this against the 18-month publication lag before concluding these firms have stopped filing entirely.
Individual Filer
168 co-filings
with matched Latin-script entity
A single Russian inventor-assignee pair anchors a distinct filing cluster
Kochetov Oleg Savelevich and its Latin transliteration KOCHETOV OLEG SAVELEVICH co-file together 168 times, an order of magnitude above any corporate pairing in the dataset, suggesting a prolific individual inventor filing under both script forms of the same name.
Treat the Cyrillic and Latin forms as one entity when assessing true filing volume.
OEM-Supplier Pairs
18 co-filings
Sumitomo Riko Company Limited + Honda Motor Co., Ltd.
Joint OEM-supplier filings are the second-strongest cluster
Sumitomo Riko Company Limited (Sumitomo Riko) paired with Honda Motor Co., Ltd. (Honda) 18 times, and with Toyota Motor Corporation (Toyota) 13 times — the two clearest examples of automotive supplier-OEM co-filing in the dataset, both now showing zero recent-year momentum.
These pairings mark where damping components were jointly claimed for specific vehicle platforms.

What's Next
Where to take this analysis
The aggregate trend and the assignee-level momentum point in the same direction: this is a field with occupied core claim space and a shrinking rate of new filing, but with sub-areas that have not been claimed as densely.
Check freedom-to-operate against the F16F core
Before filing an assembly-level damping claim, check it against the dense F16F prior art rather than the more open adjacent classes — that is where 99% of the claim density actually sits.
Explore F16F prior art in EurekaWatch for renewed filing from quiet historic leaders
Several of the largest historic filers show zero recent-year activity; a return to filing from any of them, once the publication lag clears, would be a meaningful signal for the sector's direction.
Track assignee momentum in EurekaScope claims into the under-claimed branches
Active pneumatic isolation control and building-structural tuned mass damping carry comparatively thin filing density next to the core mechanical assemblies — worth checking before assuming freedom-to-operate is the only opportunity.

FAQ
Common questions about vibration damping patents
The dataset shows a mix of large automotive suppliers, such as Sumitomo Riko Company Limited (Sumitomo Riko), and vehicle OEMs including Toyota Motor Corporation (Toyota) and Nissan Motor Co., Ltd. (Nissan), alongside a prolific individual inventor-assignee, Kochetov Oleg Savelevich, whose co-filing volume with a matched Latin-script entity outpaces any single corporate pairing. Historic volume leadership does not equal current activity: several of the largest cumulative filers show zero filings in the most recent recorded year. Anyone assessing competitive position should weight recent-year momentum alongside total historic volume, not one or the other alone.
Filing activity is shrinking. Annual filings peaked at 143 in 2017 and had fallen to 20 by the latest recorded year, with the 2022 midpoint of 70 confirming a sustained multi-year decline rather than a single volatile year. Publication lag of roughly 18 months means the most recent year's count is understated, but the multi-year trend line is clearly downward, not flat.
The overwhelming majority of records, 4,043 of 4,066, are classified under F16F, the springs-and-vibration-dampers subclass. Adjacent classes such as B32B (layered products and laminates), B60K (vehicle propulsion) and C08L (polymer compositions) appear on a subset of those same families as secondary classifications, indicating that damping materials are usually claimed as part of a mechanical assembly rather than as a standalone composition.
US20090294234A1, filed by Design, Imaging & Control, Inc., describes an adjustable vibration isolation and tuned mass damper system using an air mount between an isolated mass and its supporting base, with a supervisory controller adjusting airflow based on relative height, velocity and acceleration feedback. It is representative of active pneumatic isolation control rather than passive mechanical damping. Whether it blocks a specific new design depends on whether that design uses feedback-controlled pneumatic adjustment versus a passive or differently-sensed isolation mechanism — a claim-by-claim comparison against the granted claims, not the published abstract, is necessary before concluding freedom to operate.
The clearest under-claimed areas sit outside the dominant F16F mechanical-assembly cluster: active pneumatic isolation control, viscoelastic constrained-layer laminate formulations, building-structural tuned mass damping, and polymer additive approaches to loss-factor tuning all show materially lower filing density than the core mechanical damper assemblies. These are not empty fields, but they carry far less claim density than the crowded core, making them a more realistic starting point for a defensible new filing than another mechanical-assembly variant.
