PVDF Resin for Binders and Coatings Patents: Top Companies & Trends 2026
PVDF resin patents for binders and coatings: who leads, what they claim, and where filing has slowed
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. 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.

Common questions on PVDF binder and coating resin patents
Who holds the most patents on PVDF binder and coating resin technology?
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.
Is PVDF binder patent filing growing or slowing down?
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.
What is the difference between PVDF used as a battery binder and PVDF used as a coating resin?
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.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on PVDF Resin for Binders and Coatings covering 2015–2026, data cut-off 2026-07-31.
