What this shows Spring's Innovation Score is 30.0/100 (33rd 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 Spring?

Each dot is one of Spring’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). Spring’s own 17.7 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Spring's grants concentrate

Spring Rainbow Optics Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, Spring sits between SPF Innovations, LLC and Square Grove LLC.

Spring's three-year grant acceleration

Spring Rainbow Optics Co., Ltd shows 2 grants in 2022–2024 against only 4 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.
