Conductive Shielding Films and Gaskets Patents: Leaders & Trends 2026
Conductive Shielding Films and Gaskets Patents: Who Leads and Where the Filing Concentrates
31.5% sits with five firms. The top five assignees combined account for 391 of 1,241 records in scope, while the ranked field runs 100 companies deep with a long single-filing tail. Filings climbed from 33 in 2017 to a peak of 56 in 2020, then eased to 44 in 2021 and 39 in 2024, an 11% decline over that span. 2025 and 2026 counts are still incomplete because publication typically lags filing by around 18 months, so the most recent two years understate actual activity rather than signal a further drop.

Common questions
Who are the leading patent holders in conductive shielding films and gaskets?
Filing is concentrated at the top of a 100-company ranked field: the leading assignee holds 157 records, and the top five combined account for 391 of 1,241 records in scope, or 31.5%. Beyond the top ten, which together hold 42.4% of records, the field spreads into a long tail of companies with far fewer filings each. This pattern is typical of a mature component category — a handful of established suppliers with deep portfolios, and many smaller or newer entrants filing narrowly around specific applications.
Is the shielding gasket and film patent space still growing?
Filings peaked at 56 in 2020 and have since eased to 39 in 2024, an 11% decline over that three-year window, so growth has slowed rather than accelerated recently. The 2025-2026 figures in any dataset will look lower still, but that reflects publication lag of roughly 18 months rather than an actual drop in filing activity. Judged on the last complete year, 2024, activity remains substantial even if below the 2020 peak.
What technology areas do these patents actually cover?
Most records combine electromagnetic shielding claims with a materials or assembly context: 63.3% of the 1,241 records touch H05K (printed circuits & assemblies), while gasket-specific claims under F16J appear in 11.8%. Connector and cable-related classes (H01R, H01B) each sit near 9.9%, and polymer additive and composition classes (C08K, C08L) appear in roughly 8% of records. The pattern indicates that most applicants are protecting shielding as integrated into an electronic assembly rather than as a standalone elastomer or film material.
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.
