Optical Transceiver Coatings Patent Snapshot 2026
The optical transceiver coatings patent space is a nascent, highly concentrated field where the top five filers account for two-thirds of the activity among the largest filers, with Qingdao Lianzhi Optical Communication Technology holding the leading position. The field is still expanding on a multi-year basis, though annual volume has eased from its 2022 peak and the United States dominates as the primary filing jurisdiction.
A concentrated, early-stage field with one clear leader
Qingdao Lianzhi Optical Communication Technology leads the applicant ranking with 3 patent families, followed by Hewlett Packard Enterprise Development LP with 2. The remaining ranked applicants — including Hisense Broadband Multimedia Technology, Apple, Hitachi, Optotune Switzerland, Carl Zeiss SMT, Electronics and Telecommunications Research Institute, and LumentumRadiant — each hold 1 patent family.
The top five filers account for 67% of the combined total among the ranked applicants visible in this query, indicating a high degree of concentration for such an early-stage corpus. There is a notable tier gap between the leader (3 patent families) and the second-place filer (2 patent families), with everyone else tied at 1.

The leaders’ positions suggest that no single incumbent has yet established a visible, defensible moat. The spread of activity across diverse organizations — Chinese broadband specialists, US hyperscalers, Swiss optics firms, and Japanese conglomerates — points to a field where strategic filing could shift the competitive balance relatively quickly.
The most recent 18–24 months of filings are likely undercounted due to standard patent publication lag; the apparent drop-off in 2024–2025 should not be interpreted as a real decline in activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Growth-phase activity concentrated in laser and transmission branches
The annual filing trend and technology composition charts together show a field that entered a growth phase after 2021 and is anchored in laser and optical transmission technology, with printed-circuit and semiconductor-device branches remaining sparse.
Annual filing trend
Filings were absent in 2017, picked up in 2018 (3 patent families), fell quiet in 2019–2020, then resumed with a single filing in 2021 before peaking at 4 in 2022. Activity moderated to 2 in 2023. The 2024–2025 figures are almost certainly understated by publication lag and should not be read as a real slowdown; the three-year recent window sits 500% above the prior three-year window, confirming multi-year expansion.

H01S (Lasers and stimulated emission) is the visible branch, followed closely by H04B (Transmission, general) and G02B (Optical elements and systems). H05K (Printed circuits and assemblies) and H01L (Semiconductor devices) each register minimal coverage, marking them as the least-developed technical areas within this corpus.

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.
Qingdao Lianzhi Optical Communication Technology
Holding 3 patent families, Qingdao Lianzhi is the ranking leader in this corpus. Its technology focus sits squarely in H01S (Lasers and stimulated emission) and H04B (Transmission, general), reflecting a product-line orientation toward laser-based transceiver modules. No prior-period baseline is available in the momentum data for this entity; momentum is attributed to the related Hisense Broadband Multimedia Technology entry, which is flagged as a new entrant with 4 recent-period records, indicating that the Hisense/Lianzhi cluster is an actively expanding force in this space.
patent families: 3Hewlett Packard Enterprise Development LP
Hewlett Packard Enterprise Development LP holds 2 patent families, with its technology emphasis split evenly between H01S (Lasers and stimulated emission) and H04B (Transmission, general). This balanced distribution suggests a system-level approach to transceiver coating technology rather than a component-only focus. No applicant momentum trend entry is directly available for this entity in the evidence, so trajectory should be monitored independently.
patent families: 2Frequently asked questions
The current corpus comprises 11 patent families in scope. This is a small corpus reflecting the early-stage nature of dedicated coating IP in this product category.
Qingdao Lianzhi Optical Communication Technology leads with 3 patent families. Hewlett Packard Enterprise Development LP is second with 2 patent families. All other ranked applicants hold 1 patent family each.
The United States is the visible jurisdiction, followed by China and WIPO (PCT). Coverage outside these three jurisdictions is not evidenced in the current corpus.
The field is classified as Growth. The recent three-year filing window is 500% above the prior three-year window on a multi-year basis. Annual volume has eased from its 2022 peak, and the most recent years are further understated by publication lag.
H01S (Lasers and stimulated emission) is the leading branch, followed by H04B (Transmission, general) and G02B (Optical elements and systems). H05K (Printed circuits and assemblies) and H01L (Semiconductor devices) have the lowest coverage.
No co-filed or jointly assigned patent families are detected in the corpus. Players appear to be pursuing independent proprietary strategies, with no evidence of consortium or standards-body joint development activity to date.

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.
