This landscape covers 499 patent families filed between 2015 and 2026 that combine LiDAR-specific terminology with claims on scanning design, optical system optimization, and field-of-view optimization, classified primarily under G01S7/481, G06F30 and G01S17/89. The corpus spans both physical scanning hardware and the computational optimization methods applied to it. The most-cited foundational records date to early 3D LiDAR and time-of-flight scanning concepts, some predating the 2015 window, and continue to anchor prior-art searches in the field.

Recent-year momentum data shows Velodyne as the only tracked assignee with an active filing in the latest year, though at just one filing with flat year-over-year movement. Other historically significant filers, including Ouster and Opsys Technologies, show zero filings in the latest year with a -100% year-over-year change, suggesting a broader slowdown across previously active players rather than a single new leader emerging. Any competitive read of this space should account for that pause rather than assume continuity from earlier peak-year activity.

Filings rose from 43 in 2017 to a peak of 116 in 2019 before declining to roughly 59 by the 2022 midpoint. That pattern typically reflects an initial wave of applicants staking out core scanning-design and optical-system claims early, followed by a thinner stream of filings once the most obvious claim space is occupied. It does not necessarily mean the underlying technology has stopped advancing — it means the easiest claims in this specific search scope have largely been filed.

The clearest gaps sit in subclasses that appear far less frequently than the dominant G01S positioning class: G02B optical elements (61 records), G01J radiation measurement (42), G01C navigation and gyroscopes (35), and H01S lasers (32). Sub-areas such as multi-wavelength WDM optical design, coherent detection with phased-array integration, and field-of-view optimization specific to solid-state scanning show filing volumes well below the core scanning-design claim space. These are reasonable starting points for a novelty search before committing to a specific claim direction.

Citation counts in this dataset favor older records simply because they have had more years to accumulate citations, so the most-cited patent — with 393 citations — is not necessarily the most commercially relevant filing today. Instead, treat high citation counts as a marker of foundational influence on how later claims were drafted, useful for freedom-to-operate screening. For a read on current competitive activity, recent-year filing momentum by assignee is a better signal than citation depth.
