Patent Landscape · Bio-Based & Smart TextilesBio-based and smart textile patents: who holds the ground and where it is still open
- Concentrated at the very top. The top 5 assignees account for 74.0% of all 50 records in scope, with a long tail below tenth place.
- Filing has cooled from its 2020 peak. The field peaked at 8 records in 2020 and filings fell from 6 in 2021 to 4 in 2024, a -33% change over that span.
- Nonwovens and cigarette filters dominate the claim space. D04H nonwovens (26.0%) and A24D cigarette filters (24.0%) are the two most-claimed IPC subclasses among 50 records.

Filing Growth 2021→2024
WO
Leading Jurisdiction
Filing growth compares 2021 (6 records) with 2024 (4) — 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 50 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape tracks 50 published records filed between 2015 and the 2026 data cut-off that combine bio-based textile or fiber materials with structural or compositional claims around web structure, fiber diameter and related descriptors. It is a narrow, cross-disciplinary slice: the search pairs bio-based material language with fiber and web-structure terminology, which pulls in nonwoven filters, packaging laminates and paper compositions alongside more conventional textile claims.
The scope is small enough that a handful of assignees define the field's current shape, and large enough that the technology composition and receiving-office pattern are still meaningful. Publication lags filing by roughly 18 months, so figures for 2025 and 2026 are undercounts and should be read as provisional.

The Data
Filing trends and technology composition
Two views of the same 50 records: how filing volume has moved year over year, and which technology classes carry the claim density.
Filing trend: a 2020 peak, then a pullback
Filings rose to a peak of 8 records in 2020, then eased; the last complete year, 2024, sits at 4 records against 6 in 2021, a -33% change over that three-year span. Treat 2025 and 2026 as still filling in rather than as evidence of a further slowdown.
Technology composition: nonwovens and filters lead
D04H (nonwovens & felts) and A24D (cigars, cigarettes & filters) are each present in roughly a quarter of the 50 records, with B65D packaging, D21H pulp/paper compositions, B32B laminates and D06M textile treatment each appearing in a fifth or more. Because records can carry multiple IPC classes, these shares sum to well over 100% and should not be read as a partition of the field.
Shares are the percentage of the 50 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Representative Record
WO2025147785A1 — Biodegradable/compostable netting for forage wrap and related products
NATURE'S NET WRAP LTD.
A compostable/biodegradable netting has a web structure formed of filaments made with a blend of biopolymers of polylactic acid (PLA) and polybutylene succinate (PBS). The blend is structured to substantially degrade after six months in a soil box test at 21°C with 12-15% moisture, to have a melt flow index of 1-6, and the web structure is structured to retain sufficient strength to act as a structural retainer for a loose item for at least twelve months during transport and field exposure.Filed by Nature's Net Wrap Ltd, published 2025-07-17 — one of the most recent records in this dataset.

What the numbers mean for a filing decision
Three ways to read the same 50-record dataset, each pointing to a different practical question: where the field is crowded, where it moved fastest, and where the strongest prior art sits.
Concentration
74.0%
of 50 records held by top 5 assignees
The leaderboard is short
Five assignees account for 37 of the 50 records in scope, and the top 10 combined reach 94.0%. Below that line the field thins out sharply into single-filing entrants, which means most of the freedom to operate sits outside the leaders' declared claim scope rather than around it.
Assignee ranking, 15 companies
Momentum
-33%
2021 to 2024 filing change
Volume has eased since the 2020 peak
Filings peaked at 8 records in 2020 and stepped down to 4 by 2024, a -33% change from the 6 filed in 2021. That is a real pullback in the last fully-countable years, not a data artefact, though 2025-2026 figures are still incomplete.
Peak year 2020, 8 records
Prior art
64 citations
on the single most-cited record
Cigarette filter tow anchors the citation graph
The most-cited record and several related family members all describe biodegradable cigarette filter tow, and together they dominate the top of the citation table. That concentration of citations in one filter-tow family signals where later filers had to design around existing claims, not where new filing activity is happening now.

Players
Who is filing, and what is still open
The ranked leaders sit atop a field with a long single-filer tail; the technology composition data points to sub-areas that none of them have claimed heavily yet.
Leader
11 records
held by the top-ranked assignee
One assignee sets the pace
The leading assignee holds 11 of the 50 records in scope, roughly double the fifth-place holder's 5. That gap suggests a deliberate filing programme rather than opportunistic single filings, and it is the first name to check before filing in adjacent claim language.
Assignee ranking, leader vs fifth place
Mid-field
5 records
fifth-place assignee count
A cluster forms below the leader
Positions two through five each hold enough records to represent a real programme rather than a one-off filing, and together with the leader they make up the 74.0% top-5 concentration. Below tenth place, holdings drop to single digits and then to one-off filings.
Top 10 combined: 94.0% of 50 records
Collaboration
1 pairing
strongest co-assignee link found
Co-filing is rare in this dataset
The one co-assignee pairing identified links a Chinese forestry university with an adhesives manufacturer, an academic-industry link rather than a competitor tie-up. Outside that single pairing, records in this dataset are filed by a single named assignee.
Co-assignee pairs identified: 1

What's Next
Where to take this analysis
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, portfolio strategy, or spotting an entry point.
Run a freedom-to-operate check against the leader's claims
With one assignee holding 11 of 50 records, any filing near nonwoven or filter-tow claim language should be checked against that portfolio first.
Explore with EurekaMap the under-claimed branches before drafting
Biopolymer blend tuning and compostable netting strength claims show lower density than the core filter and packaging clusters, which is where a first claim has more room to stand.
Explore with EurekaTrack the next 18 months of filings separately
Because publication lags filing, records from 2025 and 2026 will keep arriving; treat the current -33% trend as provisional until those years fill in.

FAQ
Common questions about this landscape
The ranked leader in this dataset holds 11 of the 50 records in scope, with the top 5 assignees combined accounting for 74.0% of all records. That concentration falls off quickly after fifth place, and by tenth place a single assignee holds only 1 record. In practice this means a small number of filers have defined the current claim landscape, while everyone else in the ranking is a much smaller, more opportunistic filer.
Filing peaked at 8 records in 2020 and had fallen to 4 records by 2024, a -33% change from the 6 records filed in 2021. That is the most reliable trend read available, because publication lags filing by roughly 18 months and the 2025-2026 figures are still incomplete. Readers should not treat the very latest years as evidence of further decline until more filings publish.
Nonwovens and felts (D04H) appear in 26.0% of the 50 records, closely followed by cigarette filters (A24D) and packaging (B65D) at 24.0% each, then pulp and paper compositions, laminates and textile chemical treatment each above a fifth. Because a single record can carry several IPC classes, these percentages overlap rather than sum to a whole field. The pattern suggests the dataset's cross-disciplinary search string is pulling in filter and packaging innovation as much as conventional textile claims.
The technology composition data shows lower claim density in areas like biopolymer blend melt-flow tuning, compostable netting tensile performance, and adhesive-nonwoven bonding compared with the dense filter-tow and nonwoven clusters. These are not gaps in demand, just gaps in filed claim scope relative to the crowded core. A first filer with a specific, testable claim in one of these branches has more room to establish position than someone filing another generic nonwoven claim.
The most-cited record, US20150374030A1, describes a biodegradable cigarette filter tow and method of manufacture, and it is cited 64 times within this corpus. Several related family members covering the same invention also appear high in the citation table, which concentrates influence in one filter-tow family rather than spreading it across the field. High citation counts here reflect age and influence on later filers, not current filing activity, since citation counts inside a searched corpus favour older records.
