Silicon Photonics Waveguide Platform Patents: Leaders, Filing Trends and Open Claim Space
13.9% concentration at the top. The five leading assignees hold 677 of 4,886 records combined — real advantage, but no single firm controls the field. Filings rose from 281 in 2017 to a peak of 386 in 2021, then declined to 254 by 2024 — a 34% drop over that three-year span. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continuation of the decline.

Common questions about silicon photonics waveguide patents
Who holds the most patents in silicon photonics waveguide platforms?
Across the 4,886 records in this dataset, the leading assignee holds 157 records, with the field's top five assignees combining for 677 records — 13.9% of the total. That leadership position is meaningful but not dominant: the remaining 86.1% of records are spread across a long tail of other filers, including large network-equipment vendors, chipmakers, photonics-focused startups and research institutes. No single company controls the core waveguide claim space.
Is silicon photonics patent filing activity growing or slowing?
Filing activity peaked in 2021 at 386 records and declined to 254 by 2024, the most recent year that can be treated as complete — a 34% drop over that span. Figures for 2025 and 2026 appear lower still, but that reflects the roughly 18-month lag between filing and publication, not a confirmed continued decline. The honest read is a real pullback from a 2021 high, with the very latest trend still unresolved.
What technology areas dominate silicon photonics waveguide patents?
G02B, covering optical elements and systems broadly, touches 60.6% of the 4,886 records in scope, making it the single largest IPC category. G02F, covering optical control and modulation, follows at 25.2%, and H01S, covering lasers and stimulated emission, at 16.5%. Because a single record can carry multiple IPC classes, these shares add up to more than 100%, and they should be read as overlapping footprints rather than a strict breakdown of the field.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Silicon Photonics Waveguide Platforms covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
