What this shows OTO's Innovation Score is 33.9/100 (46th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for OTO?

Each dot is one of OTO’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). OTO’s own 21.3 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where OTO's grants concentrate

OTO Photonics Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under G01J (Measurement OF Intensity, Velocity, Spectral Content, Polarisation, Phase OR Pulse Characteristics OF Infrared, Visible OR Ultraviolet LIGHT; COLORIMETRY; Radiation Pyrometry). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2016. By volume, OTO sits between OCuSOFT, Inc. and Obsidian Sensors, Inc..

OTO's three-year grant acceleration

OTO Photonics Inc. shows 1 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
