What this shows CH's Innovation Score is 51.9/100 (top 11% 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 CH?

Each dot is one of CH’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). CH’s own 15.6 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CH's grants concentrate

CH Lighting Technology Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 68.4% of grants classified under F21Y (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO THE Form OR THE Kind OF THE Light Sources OR OF THE Colour OF THE Light Emitted). Peak complete grant year is 2022 (10 grants) versus a trough of 1 in 2019. By volume, CH sits between Caliber Imaging & Diagnostics, Inc. and China-euro Vehicle Technology Aktiebolag.

CH's three-year grant acceleration

CH Lighting Technology Co., Ltd. shows 13 grants in 2022–2024 against only 3 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.
