LTCC Module Patents: Who Leads, Where the Gaps Are 2026
Low Temperature Cofired Ceramic Module Patents: Who Holds the Ground
39.9% concentration. The top 5 assignees together hold 156 of all 391 records in scope — filing here is concentrated rather than fragmented. Annual counts run from 10 in 2017 down toward 0 by 2026; the 2021-to-2024 window shows a -100% swing from 1 record to 0, a genuine contraction rather than a lag artefact since 2024 is the last complete year.

Common questions on LTCC module patents
What counts as a low temperature cofired ceramic (LTCC) module patent?
In this dataset it is a filing that claims LTCC or cofired ceramic substrates together with at least one core process feature: green tape lamination, shrinkage matching across layers, via filling, cavity structures, silver conductor patterning or hermetic packaging. That combination is what separates an LTCC module claim from a generic ceramics or general packaging filing. The 391 records in scope were selected on exactly that basis, spanning 2015 through the 2026-07-31 data cut-off.
Who are the leading patent holders in LTCC modules?
The assignee ranking covers 100 companies, with one clear leader holding 69 of the 391 records — well ahead of fifth place at 15 and tenth place at 12. The top 5 assignees combined hold 156 records (39.9% of all records in scope), and the top 10 combined hold 222 (56.8%). Beyond that group the ranking thins into a long tail of companies holding only a handful of records each, so competitive monitoring should focus on the leader’s specific claim scope rather than treating the field as evenly contested.
Is filing activity in LTCC modules growing or shrinking?
Filing peaked in 2017 at 10 records and has declined since; the 2021-to-2024 window shows a -100% swing from 1 record down to 0, and 2024 is the last year in this dataset that can be treated as complete. That said, publication typically lags actual filing by around 18 months, so the thin 2025-2026 counts are not yet a reliable read on current activity. Treat the contraction through 2024 as real, and treat the very latest years as provisional until more data lands.
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 Low Temperature Cofired Ceramic Modules 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.
