Co Packaged Optics Patents: Who Leads, Where the Gaps Are 2026
Co Packaged Optics and Optical IO Patents
78.8% of records sit with five companies. 123 of the 156 records in scope belong to the top five assignees, with a long tail of single- and few-filing entrants behind them. Filings rose through the early 2020s to a peak of 49 records in 2023, then declined to 21 by 2024 — a 28% drop from the 2021 level of 29. Because publication trails filing by roughly 18 months, the 2025 and 2026 figures are still incomplete and should not be read as a continued decline.

Common questions about this landscape
Who holds the most patents in co packaged optics?
One assignee leads with 59 of the 156 records in this dataset, well ahead of the fifth-ranked company at 12. That gap means a competitive read of this field should start with a detailed review of the leader’s portfolio rather than treating the field as evenly split. The ranking covers 30 companies in total, so filings tail off quickly after the top few names.
Is co packaged optics patent filing still growing?
Filings rose to a peak of 49 records in 2023, then fell to 21 by 2024 — a 28% decline from the 2021 level of 29. That is a genuine pull-back over that three-year span, but publication typically lags actual filing by around 18 months, so the 2025 and 2026 counts in this dataset are still incomplete and cannot yet be read as a continued slowdown.
What technology areas dominate co packaged optics patents?
G02B, covering optical elements and systems, appears in 68.6% of the 156 records, making it the single most common classification by a wide margin. H04B, general transmission, appears in 39.7%. Packaging and thermal-adjacent classes such as H05K and H01L are present in far fewer records, which is consistent with most claim activity still centring on the optical-engine architecture itself rather than its physical integration.
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 Co Packaged Optics and Optical IO 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.
