Silicon Photonics Inverse Design Patent Snapshot 2026
Silicon photonics inverse design is a nascent, highly concentrated field: just 12 patent families are on record, with a single foundry — Taiwan Semiconductor Manufacturing Co. — holding more than half. Filing activity emerged only in 2020 and has expanded sharply on a multi-year basis, though annual volume eased from its 2023 peak and recent years remain understated by publication lag.
TSMC dominates a three-player field with no independent challengers yet
Taiwan Semiconductor Manufacturing Co. (TSMC) holds 7 patent families, placing it first among all ranked applicants; OpenLight Photonics follows with 4 patent families, and Siemens Industry Software (Mentor) holds 1 patent family.
The top five filers collectively account for 100% of the ranked applicants visible in this query’ combined total, signaling extreme concentration — effectively a three-entity field at present. The gap between TSMC (7 families) and OpenLight (4 families) is meaningful but not insurmountable for a well-resourced entrant.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Taiwan Semiconductor Manufacturing Co. (TSMC) | 7 | |
| 2 | OpenLight Photonics Inc. | 4 | |
| 3 | Siemens Industry Software Inc. | 1 |
TSMC’s position reflects its integrated role as both a process-technology owner and an EDA/design-methods innovator; OpenLight’s focus on optical elements suggests complementary, waveguide-level inverse-design work rather than direct overlap.
The most recent 18–24 months of filings are likely undercounted due to standard patent publication lag; the corpus should be treated as a lower bound on current activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity accelerated from 2020 onward, led by digital-design-flow and optical-systems classes
Two charts together capture the field’s pace and breadth: the annual filing trend shows when commercial R&D attention arrived, and the technology composition reveals which IPC branches carry the work.
Annual filing trend
No filings appear before 2020; the field then produced 3 families in 2020, a gap in 2021–2022, a surge to 4 families in 2023, and 3 more in 2024. The 2025–2026 figures are materially understated by publication lag and should not be read as a slowdown. On a recent-versus-prior three-year basis, growth stands at 133%, confirming genuine multi-year expansion despite the easing from the 2023 annual peak.

G06F (electric digital data processing) is the visible branch with 8 records, reflecting EDA and computational design-flow patents; G01R (electric and magnetic measurement), G02B (optical elements and systems), and H01L (semiconductor devices) each carry 4 records, indicating that validation, waveguide-level design, and device-integration work are all represented but secondary.

A silicon photonic device includes a substrate formed from a silicon-containing material and patterned to comprise a first waveguide and a second waveguide defining a first trench extending between the first waveguide and the second waveguide. The first waveguide and second waveguide have upper surfaces exposed for bonding to an epitaxially grown layer. The… (excerpt from the patent abstract)

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.
Taiwan Semiconductor Manufacturing Co.
TSMC holds 7 patent families and entered the field as a new entrant in the recent filing window. Its technology focus spans G06F 30 (digital data processing / EDA design flows), G01R 31 (electrical measurement and validation), and H01L 23 (semiconductor device structures) — indicating that TSMC’s inverse-design IP covers the full stack from computational optimization through physical verification to device integration. This integrated position is difficult for pure-play software or pure-play photonics firms to replicate quickly.
families: 7OpenLight Photonics Inc.
OpenLight Photonics holds 4 patent families and also entered as a new entrant in the recent filing window. Its coverage is concentrated entirely in G02B 6 (optical waveguide elements and systems), reflecting a waveguide-centric inverse-design approach distinct from TSMC’s design-flow orientation. As a fabless photonics company, OpenLight’s trajectory will depend on whether it expands into EDA-layer IP or deepens its waveguide-specific coverage.
families: 4Frequently asked questions
The current evidence corpus contains 12 patent families in scope for silicon photonics inverse design. This is a small but rapidly growing field; the most recent 18–24 months of filings are likely undercounted due to standard publication lag.
Taiwan Semiconductor Manufacturing Co. (TSMC) leads with 7 patent families, followed by OpenLight Photonics Inc. with 4 patent families, and Siemens Industry Software Inc. with 1 patent family. These three applicants account for all indexed families.
The United States is the primary filing jurisdiction with 8 patent records, followed by Taiwan and WIPO (PCT) with 2 records each. European and broader Asian jurisdictions are not prominently represented in the current corpus.
G06F (electric digital data processing, including EDA and design-flow methods) leads with 8 patent records. G01R (electrical and magnetic measurement), G02B (optical elements and systems), and H01L (semiconductor devices) each carry 4 records.
No filings appear before 2020 in the indexed corpus. Activity began in 2020 with 3 families, accelerated to 4 families in 2023, and continued in 2024. The field is in a Growth lifecycle stage with recent three-year filings 133% above the prior three-year window.
No co-applicant filings are detected in the current corpus. Each of the three applicants appears to be filing independently, which is consistent with the proprietary, vertically integrated nature of inverse-design toolchains at this early stage.

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.
