Flexible QLED Patent Snapshot 2026
The formal patent corpus for flexible QLED is extremely small — only 2 patent families in scope — split evenly between two applicants, with all filings concentrated in the United States. Activity has plateaued near its modest 2021 peak, signalling an early-stage field where most technical ground remains unoccupied.
A two-applicant field with maximal concentration
The flexible QLED patent evidence snapshot currently contains only 2 patent families in scope, divided equally between 10644137 Canada Inc and HKC Corp Ltd — each holding 1 patent family.
Concentration is absolute: the top five filers account for 100% of the ranked applicants visible in this query’ combined total, and the entire corpus is held by just two entities. There is no meaningful tier gap — the two players are peers by count.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | 10644137 Canada Inc | 1 | |
| 2 | HKC Corporation Limited | 1 |
The leaders’ positions imply that no single incumbent has established a visible blocking position; the field is effectively open to new entrants willing to build a substantive portfolio.
Activity recorded in the most recent 18–24 months may be under-counted due to standard patent-publication lag and should not be read as a definitive measure of current filing pace. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse, episodic filings anchored in organic-semiconductor and nanotechnology classes
The annual filing trend reveals isolated activity in 2021 and 2024, with no sustained growth wave. Technology composition is anchored in organic-semiconductor device classes, with nanotechnology and general semiconductor device classes appearing as secondary branches.
Annual filing trend
A single family was filed in 2021 and another in 2024; all other years in the window show zero activity. The 2024 data point sits within the publication-lag window and may not yet be fully indexed, so the apparent gap in 2025–2026 should not be read as a halt in activity.

H10K (Organic semiconductors / OLED-family devices) accounts for both families, confirming the organic-semiconductor substrate as the visible technical route. B82Y (Nanotechnology applications) and H01L (Semiconductor devices) each appear once, reflecting supplementary nanotechnology and device-architecture claims.

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.
10644137 Canada Inc
Holds 1 patent family focused on nanotechnology applications (B82Y 20, B82Y 40) and organic-semiconductor architecture (H10K 102). As the earlier filer (2021), this entity established the first formal claim position in the corpus. Momentum data does not record a recent-period surge, consistent with a single isolated filing.
families: 1HKC Corp Ltd
Holds 1 patent family spanning semiconductor device integration (H01L 25) and organic-semiconductor display architectures (H10K 59). Applicant momentum is recorded as a new entrant (▲ new entrant), indicating the 2024 filing represents HKC’s first appearance in this specific corpus. As a major display panel manufacturer, HKC’s entry may signal broader commercial intent.
families: 1Frequently asked questions
The evidence shows 2 patent families in scope for flexible QLED, held by two separate applicants — 10644137 Canada Inc and HKC Corp Ltd — each with 1 family.
10644137 Canada Inc and HKC Corp Ltd are the only two filers on record, each holding 1 patent family. There is no visible leader by count; the two are equal peers.
Both patent families in scope are filed exclusively in the United States. No filings in EPO, PCT, China, Korea, Japan, or other jurisdictions appear in the evidence.
The lifecycle evidence classifies the field as Maturity, with annual filings having plateaued near their modest 2021 peak and a recent growth rate of 0%.
H10K (Organic semiconductors, OLED-family devices) covers both families. B82Y (Nanotechnology applications) and H01L (Semiconductor devices) each appear once as secondary classes.
No co-applicant or jointly assigned filings appear in the evidence. The collaboration record is empty, indicating the field has not yet attracted academic-industry or cross-company co-filing activity.

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.
