Flexible Moisture-Barrier Encapsulation Patents: Leaders & Trends 2026
Flexible Moisture-Barrier Encapsulation Patents: Who Leads and Where the Claims Sit
A long tail behind a single leader. 19 ranked assignees cover the field, with the leader at 10 filings and the fifth-place holder already down to 5 — most of the ranking holds single-digit counts. Filings rose from 2 records in 2017 to a peak of 16 in 2022, then declined; the 2021-to-2024 window the dataset tracks moved from 5 to 0, a -100% change over that span. Because 2025 and 2026 filings are still being published, this fall should not be read as the field going quiet — only as the visible portion of a lagging dataset.

Common questions about this landscape
Who are the leading patent holders in flexible moisture-barrier encapsulation?
The assignee ranking for this dataset covers 19 companies and research institutions, with the top-ranked filer holding 10 records and the fifth-ranked holder already down to 5. That is a real but modest lead — not the kind of concentration seen in fields with one or two dominant players. University research groups, notably the team behind the most-cited implantable-encapsulation filing, appear alongside corporate filers in the ranking, which is unusual for a packaging-adjacent technology and reflects how much of this IP originated in implantable-device research.
Is patent filing activity in flexible barrier encapsulation slowing down?
The visible data shows a peak of 16 filings in 2022 followed by a sharp fall, with the tracked 2021-to-2024 window showing a -100% change. However, publication lags filing by roughly eighteen months, so 2025 and 2026 figures are still incomplete and should not be read as proof the field has gone quiet. The safest complete read is through 2024; anything drawn from 2025–2026 counts will understate true activity.
What patent claim types dominate this space?
Semiconductor device claims under H01L are the largest single class, touching 37.5% of the 48 records in scope. Coating and surface deposition claims (C23C) and diagnosis-and-surgery device claims (A61B) each sit at 27.1%, with electrotherapy device claims (A61N) close behind at 25.0%. Because a single patent can carry several IPC classes, these percentages overlap rather than sum to 100%, and they reflect that this corpus spans both the barrier materials themselves and the medical or display devices they protect.
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.
