Overview
What the 3D woven composite patent record shows
3D woven composite patents sit at the intersection of weaving technology and composite shaping: a record typically claims a preform or fabric architecture (D03D) together with a resin, layup or moulding step (B29C or B32B). The scope tracked here covers 32 published records between 2015 and 2026, drawn from records whose claims or title language explicitly reference 3D woven composite structures used in textile, fabric, fiber or yarn contexts.
The dataset is small enough that individual filings move the picture noticeably: a single well-cited fiber-glass patent, and a single additive-manufacturing crossover filing, each shape a disproportionate share of what counts as prior art in this space. That makes citation counts and IPC composition more informative here than filing volume alone.

The Data
Filing trend and technology composition
Two views of the same 32-record scope: how filings have moved year on year, and which IPC subclasses the claims actually sit in.
Filing activity, 2017–2026
Filings ran from 2 records in 2017 to a peak of 7 in 2018, and the most recent year is partial and undercounted because publication typically lags filing by around 18 months. Read the tail of the trend as a floor, not a ceiling.
IPC subclass composition
D03D (woven fabrics and weaving) appears in 96.9% of the 32 records in scope, confirming that nearly every filing anchors its claims in fabric architecture rather than treating the textile as incidental. B29C (shaping of plastics) follows at 37.5%, and B32B (layered products) at 18.8% — both expected companions to a woven preform claim. Because records can carry multiple classes, these shares add up to more than 100% of the record total, and that overlap is the point: it shows how tightly weaving and composite-shaping claims are co-filed.
Shares are the percentage of the 32 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts are drawn from the same 32-record scope and favour older filings, which have had more time to accumulate citations. Treat them as a signal of influence on the field, not of current commercial importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

What the ranking and the citations tell a filer
Three findings a reader could not get from browsing the raw list of records.
Concentration at the top
19 records
leader's filing count
One filer dominates a ten-company ranking
The ranked leader holds 19 records against a fifth-place count of 1 and a tenth-place count of 1. That gap is wide enough that a new entrant should assume the leader's claim set defines the baseline for any weaving-plus-shaping combination, and should search that portfolio specifically before drafting around it.
Based on the 10-company assignee ranking
Peak filing year
7 records
in 2018
Activity peaked in 2018 and has not repeated it
2018 remains the high-water mark for filings in this scope, with the trend running lower in the years since. Combined with the 18-month publication lag, the most recent years understate real filing activity, so the apparent slowdown should not be read as the field going cold.
Filing trend, 2017–2026
Unclaimed intersection
1 of 32
records touch B33Y (additive manufacturing)
3D printing crossover is claimed once
Only one record in the scope combines 3D woven composite claims with additive manufacturing (B33Y), against 12 records touching B29C plastics shaping generally. That single filing, on woven composites made by additive manufacturing, currently stands largely alone at that intersection.
IPC subclass composition, 32 records
Citation concentration
27 citations
top-cited record
Influence concentrates in a small number of older filings
The most-cited record in the scope carries 27 citations, more than the next several combined. Because citation counts favour older records simply by virtue of time in the corpus, this signals historical influence on downstream drafting rather than current commercial weight.

What's Next
Where to take this analysis
The dataset points to specific next steps rather than a general research programme.
Map the leader's full claim set
With one filer holding 19 of the ranked records, the practical first step is a claim-by-claim read of that portfolio before drafting anything that combines weaving architecture with a shaping or resin step.
Run a freedom-to-operate check in EurekaWatch the additive-manufacturing crossover
Only one record currently claims 3D woven composites made by additive manufacturing. That gap is narrow enough that a well-drafted claim there could stand largely uncontested for now.

FAQ
Common questions about 3D woven composite patents
One assignee holds 19 records in a ranked field of 10 companies tracked in this scope, with the fifth-place and tenth-place entrants each holding just 1 record apiece. That is a sharply top-heavy distribution: a single leader followed by a long tail of much smaller filers. Anyone assessing freedom to operate in this space should start with that leader's portfolio rather than treating the field as evenly spread.
Almost all records in this scope (96.9% of 32) sit in D03D, the woven fabrics and weaving classification, confirming that the fabric architecture itself is the core claimed subject matter. A large minority also touch B29C plastics shaping (37.5%) or B32B layered products (18.8%), reflecting how these preforms are typically claimed alongside a resin or moulding step. Smaller pockets cover glass compositions, polymer additives, yarn texturing and additive manufacturing.
Filing peaked in 2018 at 7 records within the years captured by this dataset (2017 through 2026). Activity in the years since has run below that level, though the most recent year is partial and, like any recent patent year, understated because publication typically lags filing by around 18 months. That means the true 2025–2026 filing level will only become clear once those applications publish.
US20120064788A1 is the most-cited record in this scope, filed by PPG Industries Ohio, and it claims fiber glass strand, yarn, fabric and composite compositions selected for specific electrical and mechanical properties such as low dielectric constant and specific strength. It does not claim 3D weaving architecture itself, so it constrains glass-fiber material composition choices for reinforcement applications rather than fabric geometry. A related PPG filing, US20160264453A1, covers closely overlapping subject matter and should be checked alongside it.
Yes — the clearest gap in this scope is the combination of 3D woven fabric architecture with additive manufacturing, which appears in only 1 of the 32 records tracked here against 12 records touching plastics shaping generally. Co-filing between assignees is also sparse, with only 8 co-assignee pairs and none repeating, suggesting most development has happened independently rather than through joint programmes. Both signals point to room for a differentiated claim at the weaving-plus-3D-printing intersection.
