Optical Image Stabilization Actuators Patents: Leaders & Trends 2026
Optical Image Stabilization Actuator Patents: Who Leads and Where the Claim Space Is Still Open
Concentration is moderate, not dominant. the top 5 assignees hold 29.4% of all 11,771 records in scope, and the top 10 hold 42.4% — leaving well over half the field to a long tail of filers. Filings rose to a peak of 803 in 2021 before falling to 396 by 2024, a -51% change over that span. The 2025 and 2026 figures are understated because publication typically lags filing by around 18 months — treat the recent-year drop-off as incomplete data, not a confirmed decline.

Frequently asked questions
Who holds the most patents in optical image stabilization actuators?
One assignee leads the ranking with 1,168 records, well ahead of the fifth-place filer at 430 and tenth place at 215. However, the top 5 filers combined account for only 29.4% of all 11,771 records in scope, and the top 10 for 42.4%, so no single company controls the field outright. A large share of filings sits with entities outside the ranked leaders, which matters for freedom-to-operate work since blocking claims can come from smaller, less-tracked filers.
Is patent filing in OIS actuators growing or slowing down?
Filings peaked at 803 in 2021 and had fallen to 396 by 2024, a -51% change over that three-year span. That said, patent publication typically lags actual filing by around 18 months, so the 2025 and 2026 counts in this dataset are still incomplete and should not be read as a confirmed decline. The more accurate description is a post-2021 plateau rather than a technology in retreat.
What is the difference between OIS actuator patents and hard-disk voice coil motor patents?
The two overlap substantially in this dataset because both use voice-coil motors with hall-sensor feedback for precise closed-loop positioning. G11B, the storage-focused IPC subclass, covers 27.6% of all records in this search, nearly matching G02B (optics, 26.3%) and H04N (imaging, 26.9%). Because the underlying control mechanism is shared, patent drafters and searchers in camera modules should not ignore storage-device prior art, and vice versa.
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 Optical Image Stabilization Actuators 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.
