What this shows Chengdu's Innovation Score is 46.0/100 (top 22% 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 19.4 claims/patent is ABOVE the 17.1 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 Tianma Micro-Electronics Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 68.4% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2018. By volume, Chengdu sits between Celgene International II Sàrl and ClearPoint Neuro, Inc..

Chengdu's three-year grant acceleration

Chengdu Tianma Micro-Electronics Co., Ltd. shows 11 grants in 2022–2024 against only 5 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.
