What this shows Chiral's Innovation Score is 32.5/100 (41st 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 Chiral?

Each dot is one of Chiral’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). Chiral’s own 15.4 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chiral's grants concentrate

Chiral Photonics, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 92.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2015. By volume, Chiral sits between Chan Li Machinery Co., Ltd. and Comeup Industries Inc..

Chiral's three-year grant acceleration

Chiral Photonics, Inc. shows 2 grants in 2022–2024 against only 11 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.
