What this shows Chengdu's Innovation Score is 34.9/100 (49th 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 17.6 claims/patent is ABOVE the 12.8 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 Sicore Semiconductor Corp. Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 35.7% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2022. By volume, Chengdu sits between Ceska Zbrojovka a.s. and Chuango Security Technology Corporation.

Chengdu's three-year grant acceleration

Chengdu Sicore Semiconductor Corp. Ltd. shows 3 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.
