What this shows Chengdu's Innovation Score is 30.5/100 (34th 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 Chengdu?
Each dot is one of Chengdu’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). Chengdu’s own 16.7 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Chengdu's grants concentrate
Chengdu BOE Display Sci-tech Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 83.3% of grants classified under G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica). By volume, Chengdu sits between Checkpoint Mobile Security Ltd and China National Digital Switching System Engineering & Technological R&D Center.
Chengdu's three-year grant acceleration
Chengdu BOE Display Sci-tech Co., Ltd. shows 1 grants in 2022–2024 against only 0 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.
