Carpet Manufacturing Patents: Top Filers & Filing Trends 2026
- Filing has cooled since 2017. The peak year logged 13 records; by the 2022 midpoint it was down to 8, and the trend has not recovered.
- Ownership is concentrated but not locked up. The top 5 assignees hold 17.9% of all 521 records and the top 10 hold 30.9% — leaving most of the field to single- or low-count filers.
- Coated and impregnated fabric claims dominate. D06N covers 76.0% of records, more than double the share of the next-largest class, tufting technique (D05C).
What this patent set covers
This landscape tracks 521 published records at the intersection of carpet construction and the specific technical problems that separate a working product from a failed one: tuft bind strength, recyclable mono-material carpet construction, stain resistance treatment, dimensional stability, and backing adhesive emission. The search combines carpet-specific title/abstract terms with those problem phrases and restricts to three IPC groups: tufting equipment (D05C17), coated and impregnated fabrics (D06N7), and layered products (B32B5).
Coverage runs from 2015 through the July 2026 data cut-off. Because publication typically lags filing by around 18 months, the last one or two years in any trend understate actual filing activity and should be read as provisional rather than a real drop-off.

Trend, geography and technology mix
Three views of the same 521 records: when they were filed, which IPC subclasses they sit in, and where applicants sought protection.
A market past its filing peak
Filings ran at 13 in 2017, the high point of the window, and had fallen to 8 by the 2022 midpoint before continuing to decline toward the partial 2026 count of 1. Read against the 18-month publication lag, the true recent-year picture is somewhat higher than shown, but the multi-year decline from 2017 predates that lag and looks real.
Backing chemistry, not tufting hardware, carries the claim volume
D06N (coated and impregnated fabrics) appears in 76.0% of the 521 records, far ahead of D05C tufting technique (39.0%) and B32B layered products (38.8%). Smaller but present classes — D06M textile chemical treatment (11.3%), C08K polymer additives (6.1%) and B29B plastics preparation (5.8%) — mark where backing and recyclability work overlaps with materials chemistry rather than loom mechanics.
Shares are the percentage of the 521 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Carpet backing components and methods of making and using the same
A carpet backing, such as a primary carpet backing, is a composite material comprising a woven fabric mechanically coupled to a non-woven fabric. The woven fabric component may include monofilament warp yarns and monofilament fill yarns, woven using a plain weave. The non-woven fabric component comprises synthetic fibers. The design combines the dimensional stability of non-woven fabric backings with the healability of woven fabric backings.Filed by Aladdin Manufacturing Corporation, published 2001-08-23 — predates this window but defines the woven/non-woven composite approach that later dimensional-stability claims build on.

Three patterns worth acting on before drafting new claims in this space.
No single owner controls the field
The top 5 assignees together hold 17.9% of all 521 records, and the top 10 hold 30.9%. That leaves nearly 70% of the corpus spread across the rest of the ranked 100 companies, many with only a handful of filings — a fragmented rather than gated field.
Activity has been declining, not accelerating
The peak year of 13 records in 2017 gave way to 8 at the 2022 midpoint and a partial count of 1 so far in 2026. Even allowing for publication lag on the newest filings, the multi-year direction is downward rather than a late-cycle dip.
Backing coatings are the dense zone
D06N coated and impregnated fabrics appears in 76.0% of records, well ahead of tufting technique (D05C, 39.0%) and layered products (B32B, 38.8%). New claims aimed squarely at backing coating formulations are entering the most crowded part of the map.
Foundational backing patents still anchor prior art searches
The most-cited record in this set, on carpet construction and backings, carries 230 citations — well ahead of the rest of the top-cited group. High citation counts here reflect decades of accumulated influence in a searched corpus that favours older filings, not current filing activity.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to carpet manufacturing, with the prior art for and against each one.
Who is filing, and where the room to move sits
The ranked assignee list runs to 100 companies drawn from the 521 records in scope. Ownership at the top is real but partial, and recent-year momentum has gone quiet across the named leaders.
A modest lead, not a monopoly
The top-ranked assignee holds 20 of the 521 records, with fifth place at 16 and tenth place at 12. The gap between first and tenth is narrow enough that no single company's portfolio forecloses the field.
Recent-year filing has gone quiet at the top
Every one of the assignees tracked for recent-year momentum shows 0 filings in the latest year, consistent with the overall decline from the 2017 peak. This is a field where established players are not currently pressing new claims, which changes the calculus for a new entrant.
Co-filing is rare and mostly individual-linked
Only 10 co-assignee pairs appear across the dataset, and the strongest pair links a corporate assignee to a named individual inventor rather than two companies. Cross-company joint filing is not a feature of this field.
| Assignee | Recent year | YoY |
|---|---|---|
| Dow Global Technologies LLC | 0 | — |
| E.I. du Pont de Nemours & Co. | 0 | — |
| Koninklijke Philips N.V. | 0 | — |
| Lobonia Ltd. | 0 | — |
| DARWIN ENTERPRISES INC | 0 | — |
| Tak Fast Sistemz SA | 0 | — |

Where to take this
The dataset points to a fragmented field with declining recent activity and a clearly dominant technology class. Two directions follow from that.
Map the white space before drafting
Under-claimed branches like recyclable mono-material construction and low-emission adhesive formulations sit next to the dense D06N core rather than inside it — a first claim there faces a thinner prior-art field.
Explore white space in EurekaWatch for a re-entry, not an incumbent lockout
With every tracked leader at 0 filings in the latest year, the field is more likely to see a new entrant reset the pace than an incumbent extend a lead. Track filing resumption rather than assuming continuity.

Across the 521 records in this dataset, the top-ranked assignee holds 20 records, with the fifth-place company at 16 and the tenth at 12. The top 5 assignees combined account for 17.9% of all 521 records, and the top 10 combined account for 30.9%. That leaves close to 70% of filings spread across the remaining companies in the ranked list of 100, so no single company dominates the field outright.
Filing has been declining. The peak year in this window was 2017 at 13 records, activity had fallen to 8 by the 2022 midpoint, and the partial 2026 count sits at 1. Publication typically lags filing by around 18 months, so the most recent one to two years will look understated, but the multi-year direction from 2017 onward is a real decline rather than a lag artefact.
Coated and impregnated fabric technology, IPC class D06N, appears in 76.0% of the 521 records in scope, making it by far the densest area. Tufting technique (D05C) and layered products or laminates (B32B) follow at 39.0% and 38.8% respectively. Smaller but present areas include textile chemical treatment (D06M, 11.3%) and polymer additives (C08K, 6.1%), which mark where backing chemistry work intersects with materials science.
The dataset shows lower filing density in sub-areas adjacent to the core backing and tufting classes, including recyclable mono-material tufted construction, low-emission backing adhesive formulations, and nonwoven-only approaches to dimensional stability. These sit next to heavily filed D06N and D05C territory but are not saturated by it, which typically means a thinner prior-art field for a first claim drafted specifically around one of them.
Rarely. This dataset identifies only 10 co-assignee pairs across the full 521-record set, and the strongest of those links a corporate assignee to a single named inventor rather than two separate companies. Cross-company joint filing is not a common pattern here, which suggests most R&D in this field is being protected in-house rather than through formal filing partnerships.
