What this shows Qing's Innovation Score is 60.7/100 (top 3% 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.

Where Qing's grants concentrate

Qing Ding Precision Electronics (HUAIAN) Co., Ltd is a focused PatentsView assignee: 29 CPC subclasses with 89.6% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2022 (22 grants) versus a trough of 1 in 2019. By volume, Qing sits between Nordischer Maschinenbau Rud. Baader GmbH & Co. KG and Stats LLC.

Qing's three-year grant acceleration

Qing Ding Precision Electronics (HUAIAN) Co., Ltd shows 55 grants in 2022–2024 against only 14 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.
