What this shows Chengdu's Innovation Score is 42.9/100 (top 30% 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 16.0 claims/patent is ABOVE the 12.4 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 Analog Circuit Technology Inc is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under G11C (Static Stores). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2024. By volume, Chengdu sits between Chem Optics Inc and Chertoff Group, LLC.
Chengdu's three-year grant acceleration
Chengdu Analog Circuit Technology Inc shows 3 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.
