Embedded Trace Substrate Patents: Top Companies & Filing Trends 2026
Embedded Trace and Fine Line Substrate Patents: Who Leads and Where the Gaps Sit
Concentrated at the top. Five assignees hold 64.6% of the 158 records in scope, and the ranked leaders extend to 26 companies with a long tail beyond them. Filings rose from 6 in 2017 to a peak of 24 in 2022, then declined to 11 by 2024, a 31% drop over the 2021-2024 window. 2025 and 2026 figures are still filling in due to publication lag and should not be read as a continued decline.

Common questions on embedded trace substrate patents
Who holds the most patents on embedded trace substrates?
The ranked list for this dataset covers 26 companies, and the leader holds 30 of the 158 records in scope — more than double the fifth-place count of 13. The top five assignees combined account for 64.6% of all records, so a small group of large electronics and packaging manufacturers controls most of the claim space. Beyond the top ten, which together hold 87.3% of records, filing activity thins out into a long tail of companies with only a handful of filings each.
Is embedded trace substrate patent filing still growing?
Filing activity peaked at 24 records in 2022 and has since declined, falling from 16 in 2021 to 11 in 2024 — a 31% drop over that three-year span. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in any dataset are still incomplete and should not be read as evidence of a continued slowdown. 2024 is the most recent year that can reasonably be treated as a complete filing year.
What is the difference between embedded trace substrate and fine line substrate patents in this dataset?
Both terms are searched together in this landscape because the underlying manufacturing techniques — semi-additive processing, seed layer etching, dry film resist — overlap heavily between the two. Records are classified predominantly under H05K (printed circuits, 53.2% of records) and H01L (semiconductor devices, 51.9% of records), and many records carry both classes, indicating the two substrate types are usually claimed as part of the same packaging process rather than as separate technologies.
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 Embedded Trace and Fine Line Substrates covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
