Static Control and ESD Protection in Fabs: Patents, Leaders and Filing Trends
24.0% concentration at the top. The five leading assignees hold 1,585 of 6,609 records in scope — a meaningful cluster, but with 76% of filings spread across a long tail. Annual filings rose from 184 in 2017 to a peak of 221 in 2021, then fell to 78 by 2024 — a 65% decline over that span. Treat 2025 and 2026 as understated: publication typically lags filing by around 18 months, so the most recent bars will fill in as later data arrives.

Common questions about this landscape
Who holds the most patents in static control and ESD protection for fabs?
One assignee leads the ranked field with 646 records, well ahead of the fifth-place holder at 175 and tenth place at 67. The top five assignees combined hold 1,585 records, which is 24.0% of the 6,609 records in scope, while the top ten reach 30.6%. That leaves a majority of filings spread across a long tail of smaller filers, so no single company controls the field outright.
Is patent filing activity in this field growing or slowing?
Filings rose from 184 in 2017 to a peak of 221 in 2021, then declined to 78 by 2024 — a 65% drop over that three-year span. The 2025 and 2026 figures shown in the trend are understated because publication typically lags filing by about 18 months, so they should not yet be read as a continuation of the decline. The honest read is that the field cooled meaningfully after 2021, with the most recent trajectory still uncertain.
Which technology areas see the most patent claims?
Semiconductor devices (IPC class H01L) account for 34.4% of the 6,609 records in scope, making it by far the densest claim area. Diagnosis and surgery filings (A61B) at 14.8% and protective circuit arrangements (H02H) at 12.5% form the next tier, reflecting the dual scope of the search across fab-level static control and sensor-device ESD protection. Because records can carry multiple IPC codes, these shares add up to more than 100%, which is expected rather than an error.
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.
