Smart High-Barrier Film Patent Snapshot 2026
The Smart High-Barrier Film patent corpus is extremely narrow, with a single patent family on record, filed in 2019 and held by Lintec Corporation. Activity has been absent since that peak year, placing the field in a decline stage with substantial room for new entrants to establish IP positions.
Lintec Corporation holds the sole position in a nascent, highly concentrated field
The Smart High-Barrier Film evidence snapshot contains 1 patent family in scope, assigned entirely to Lintec Corporation, which ranks first and alone among identified filers.
Concentration is absolute: the top five filers account for 100% of the combined total of the ranked applicants visible in this query, a figure that reflects the extreme sparsity of this defined topic rather than a contested oligopoly.

Lintec’s sole position signals that the company identified a specific intersection of barrier laminate and flexible OLED substrate technology early, but has not followed up with additional filings, leaving the surrounding space effectively open.
The corpus reflects filings retrieved through the search date; the most recent 18–24 months are subject to publication lag and should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2019 filing defines the entire activity profile; no subsequent filings are recorded
The annual trend chart and technology composition together characterize this field as a single-event corpus anchored in layered product and adhesive chemistry with an OLED device application.
Annual filing trend
One family was filed in 2019; all other years from 2017 through 2026 show zero activity. The lifecycle stage is Decline, with annual volume having eased entirely from its 2019 peak. Years 2025–2026 are additionally subject to publication lag and cannot be interpreted as confirmed zero activity.

The single family spans three IPC branches: B32B (layered products and laminates), C09J (adhesives), and H10K (organic semiconductors including OLED devices). This tri-branch fingerprint indicates the patent covers a laminated barrier construction with adhesive layers designed for a flexible organic electronic application.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Lintec Corporation
Lintec holds 1 patent family covering a laminated barrier adhesive sheet for repeatedly-bent flexible devices, spanning B32B layered products, C09J adhesives, and H10K organic semiconductors. Applicant momentum data is not available for this corpus given the single-event filing history. The company’s focus on flexible OLED substrate protection aligns with broader industry trends in foldable display materials.
families: 1No challenger identified
No second-ranked applicant exists in this corpus. The challenger position is vacant, reflecting the extreme sparsity of the Smart High-Barrier Film patent landscape as currently defined. Any organization filing in this space would immediately occupy the second position.
families: 0Frequently asked questions
The corpus contains 1 patent family in scope as retrieved from PatSnap Eureka. This reflects a very narrowly defined topic query; broader searches on adjacent barrier film or flexible encapsulation technology would return larger corpora.
Lintec Corporation is the sole identified filer, holding the one patent family on record. No other applicants appear in the ranking.
The single family spans three IPC branches: B32B (layered products and laminates), C09J (adhesives), and H10K (organic semiconductors including OLED devices), indicating a laminated adhesive barrier sheet designed for flexible organic electronic applications.
The field is classified as Decline. Annual filings peaked in 2019 with the single known family and have recorded zero activity in all subsequent years captured in the dataset. Years 2025–2026 remain subject to publication lag.
China is the only jurisdiction of record for this corpus. No counterpart filings in the United States, Europe, Japan, South Korea, or other major patent offices have been identified under this topic definition.
The top-cited document in the corpus is a patent relating to an adhesive sheet for repeatedly-bent laminated members and repeatedly-bent devices, which has received 4 citations. This is consistent with it being the sole family in the dataset.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
