Laser Lighting Efficacy Patent Snapshot 2026
A small, highly concentrated field dominated by Kyocera SLD Laser and Signify Holding, with the United States as the primary filing jurisdiction. Annual volume peaked in 2021 and has since eased, signaling a maturing technology cycle with selective remaining white space in adjacent application areas.
Kyocera SLD Laser leads a tightly concentrated field
Kyocera SLD Laser Inc holds the top position with 11 patent records, followed by Signify Holding BV with 7 and Supervision Laser Tech Suzhou Co Ltd with 5. The top five filers collectively account for 58% of the ranked applicants visible in this query’ combined total, indicating a highly concentrated visible assignee structure.
A clear three-tier gap separates the leaders from the rest: Kyocera SLD Laser and Signify Holding anchor the first tier, while Supervision Laser Tech Suzhou, Ushio Inc, and Soraa Laser Diode form a mid-tier at 4–5 patent records each. All remaining applicants hold two or fewer patent records, pointing to a long tail of fragmented smaller players.

Kyocera SLD Laser’s lead, built primarily on optical elements and pictorial communication routes, implies strong blocking coverage in beam-shaping and projection-oriented laser lighting. Signify’s position in light-source and lighting-component branches reflects a different commercial focus on general illumination efficacy.
Filing counts for the most recent 18–24 months are likely under-reported due to publication lag and should not be read as a final measure of current activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2021 filing peak, now easing, with broad optical and illumination coverage
The annual filing trend reveals a field that spiked in 2021 and has since contracted, while the technology composition chart shows that light-source and optical-element branches are visible in with notable secondary coverage in video communication and laser physics.
Annual filing trend
Filings grew from 2017 through a clear peak of 8 records in 2021, then fell sharply in 2022–2023. The 2024–2026 bars should be treated as incomplete given standard publication lag of 18–24 months; the apparent low values do not confirm a continued decline.
↗ Hover for values · click a bar to ask EurekaTechnology composition
F21K (light sources including LED and laser) is the visible branch, followed by F21V (lighting device components) and G02B (optical elements and systems). H01S (lasers and stimulated emission) and H04N (pictorial communication) form a meaningful secondary cluster, reflecting the field’s dual emphasis on illumination hardware and laser-driven imaging. Several branches — including F21S, G01S, B60Q, and F21W — appear at very low counts, marking the adjacent white space discussed in the next section.

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.
Kyocera SLD Laser Inc
With 11 patent records, Kyocera SLD Laser holds the largest portfolio in this corpus. Its technology emphasis falls on optical elements and systems (G02B 26, G02B 27) and pictorial communication (H04N 9), indicating a focus on laser-based projection and beam-steering applications rather than broad-spectrum illumination. No momentum data is available for this applicant in the recent filing window.
patent records: 11Signify Holding BV
Signify Holding holds 7 patent records and entered this specific corpus as a new entrant in the recent filing window, with 2 recent records signaling renewed interest. Its technology focus is concentrated in F21K 9 (light sources) and F21V 7 and F21V 9 (lighting device components), consistent with a general-illumination efficacy strategy rather than the imaging or positioning routes pursued by Kyocera SLD Laser.
patent records: 7Frequently asked questions
The corpus covers 34 patent families in scope. This is a relatively small field, reflecting either an early-stage or already-consolidated technology niche rather than a mass-market patent domain.
Kyocera SLD Laser Inc leads with 11 patent records, giving it more than twice the count of the second-ranked applicant, Signify Holding BV, which holds 7 patent records.
The United States leads with 22 patent records, followed closely by China with 20. Europe (EPO) has 5, WIPO (PCT) has 4, and South Korea has 2. EPO and PCT coverage is thin relative to the US and China totals.
Annual filings peaked at 8 records in 2021 and have eased since. The lifecycle assessment places the field in a decline stage, meaning the rate of new filings has contracted from its peak. Data for 2024–2026 is likely incomplete due to publication lag and should not be read as a final indicator.
F21K (light sources including LED and laser) is the most represented branch, followed by F21V (lighting device components), G02B (optical elements and systems), F21Y (light-source form index), and H01S (lasers and stimulated emission). H04N (pictorial communication) also carries significant coverage, reflecting laser projection applications.
No co-applicant filings are recorded within the corpus. The field has developed without documented cross-institutional patent alliances, at least within this dataset. Academic entrants such as Huazhong University of Science and Technology and Xiamen University are present but appear to file independently.

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.
