PVDF Resin for Binders and Coatings Patents: Top Companies & Trends 2026
- 16.3% concentration at the top. the five leading assignees hold 1,503 of 9,197 records in scope, with a long tail of single- and few-filing entrants behind them.
- Battery use dominates the class mix. H01M battery and cell claims sit on 47.2% of records, far ahead of C08L polymer composition claims at 10.6%.
- Filing has eased from its 2022 peak. 594 records published in 2022, with the 2021-to-2024 span down 15% as several leading filers pull back year-on-year.
Filing growth compares 2021 (482 records) with 2024 (410) — 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 9,197 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks patent activity naming polyvinylidene fluoride (PVDF) in binder and coating-resin contexts, searched against technical markers such as crystalline phase, swelling ratio, dehydrofluorination, gloss retention, slurry rheology and adhesion peel. The 9,197 records span 2015 through the mid-2026 data cut-off, so filings from the most recent one to two years are still arriving in public databases.
PVDF's role as a binder for lithium-ion electrode slurries pulls most of this activity toward battery manufacturing, but the same polymer chemistry underpins protective and decorative coating resins where gloss retention and weatherability claims dominate instead. Reading the two branches together shows where battery-driven volume is crowding claim space and where coating-specific chemistry still has room.

Filing trend and technology composition
Two views of the same 9,197 records: how filing volume has moved year over year, and which IPC subclasses carry the claims.
A 2022 peak, then a measured pullback
Annual publications rose from 469 in 2017 to a peak of 594 in 2022. The 2021-to-2024 window, the last span both years of which are close to complete, is down 15% (482 to 410). Later years in the chart will fill in further as publication catches up with filing, typically by about 18 months.
Battery use anchors the class mix
H01M (batteries, cells and fuel cells) appears on 47.2% of the 9,197 records, roughly four and a half times the next class. C08L polymer compositions (10.6%), C09D coatings, paints and inks (8.5%), C08K additives (7.8%), C08F addition polymers (7.3%), B32B laminates (6.8%) and C08J polymer processing (6.2%) round out the picture. Because a single record can carry several IPC codes, these shares add up to well over 100% and should be read against the 9,197-record total, not against each other.
Shares are the percentage of the 9,197 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three patterns stand out once volume, class mix and momentum are read together.
Leadership is concentrated but not locked up
The top five assignees hold 1,503 records (16.3% of all 9,197 in scope) and the top ten hold 2,490 (27.1%). That leaves the majority of filing activity spread across a long tail of smaller and single-filing entrants, which is typical of a chemistry with many downstream applications rather than one dominated by a handful of blocking patents.
Volume has eased from its 2022 high
Filings peaked at 594 in 2022 and the complete 2021-2024 span shows a 15% decline. Several of the most active recent filers also show sharp year-on-year drops in their latest reported year, though the newest one to two years in any patent dataset are understated because publication lags filing by roughly 18 months.
Battery binder use dominates the claim landscape
Nearly half of all records touch H01M battery and cell claims, reflecting PVDF's role as the standard lithium-ion electrode binder. Coating-specific classes such as C09D (8.5%) and polymer processing under C08J (6.2%) are comparatively thin, suggesting less claim pressure outside the battery-driven core.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to pvdf resin for binders and coatings, with the prior art for and against each one.
Who is active, and where they are pulling back
The ranked list covers 100 companies drawn from the full 9,197-record set. Reading rank alongside recent momentum shows which filers are still building position and which have gone quiet.
A clear leader ahead of a tight next tier
The top-ranked assignee holds 443 records, well ahead of the fifth-place filer at 233 and tenth place at 164. The gap between first and fifth is wide enough that a single filer's strategy shifts can move the overall trend line.
Battery-groups co-file more than coatings players
The strongest co-assignee pairings link large battery and electronics groups filing jointly with affiliated subsidiaries, consistent with the H01M-heavy class mix. Coating-resin specialists show fewer such pairings in this dataset.
Several top filers show sharp recent declines
More than one of the most active assignees shows a steep year-on-year drop in its latest reported year, including declines of -22%, -83%, -86% and -100% among named filers. Some of this reflects real strategy shifts; some reflects publication lag, since the newest filing year is always the least complete.
| Assignee | Recent year | YoY |
|---|---|---|
| Panasonic Intellectual Property Management Co., Ltd. | 7 | -22% |
| LG Energy Solution Ltd. | 2 | -86% |
| Samsung Electronics Co., Ltd. | 1 | -83% |
| 3M Innovative Properties Co. | 0 | -100% |
| LG Chem, Ltd. | 0 | — |
| Arkema Inc. | 0 | -100% |

The ranked assignee list covers 100 companies drawn from 9,197 records, with the leading filer holding 443 records against 233 for the fifth-place company and 164 for tenth place. The top five combined account for 16.3% of all records and the top ten for 27.1%, which leaves most of the field spread across a long tail of smaller filers. This is a moderately concentrated field rather than one locked up by a single company.
Filings rose to a peak of 594 records in 2022, and the last fully comparable three-year span, 2021 to 2024, shows a 15% decline (482 down to 410). Data from 2025 onward looks lower still, but that is expected: publication typically lags actual filing by around 18 months, so the newest one to two years always understate real activity. The safest read is a plateau-to-mild-decline from the 2022 peak, not a collapse.
In this dataset, battery-related claims under H01M cover 47.2% of all 9,197 records, reflecting PVDF's standard role as the binder holding electrode active material and conductive additive together in lithium-ion slurries. Coating-resin claims cluster instead under C09D (8.5%) and relate to properties like gloss retention and adhesion peel for protective or decorative films. The two branches share base polymer chemistry but diverge sharply in claim focus, and coating-specific classes carry noticeably less filing density.
US6991759B2 claims a process for preparing a semi-conducting polymer film containing the beta crystalline phase of PVDF, achievable at low temperature and low electric field, aimed at piezoelectric and semi-conducting applications such as tactile sensors and touch-sensitive switches. It is a processing-route patent rather than a composition-of-matter patent, so it constrains how beta-phase film is made rather than blocking all beta-phase PVDF outright. Anyone filing in the crystalline-phase control branch should check whether their process falls inside its low-temperature, low-field processing window.
The class data shows battery-binder claims under H01M crowding nearly half of all records, while coating-specific classes such as C09D and polymer-processing class C08J carry a fraction of that density. Sub-areas like gloss-retention formulations, slurry rheology modifiers for thick-film coating, and dehydrofluorination-resistant blends show comparatively thin filing activity relative to the battery core. These pockets are worth a closer freedom-to-operate check before assuming the space is occupied, since low density here reflects less claim pressure rather than technical infeasibility.
