What this shows Rays's Innovation Score is 37.7/100 (top 43% 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 Rays?

Each dot is one of Rays’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). Rays’s own 18.5 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rays's grants concentrate

Rays Optics Inc. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2019. By volume, Rays sits between Quad/Graphics, Inc. and Riprup Company S.A..

Rays's three-year grant acceleration

Rays Optics Inc. shows 12 grants in 2022–2024 against only 9 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.
