What this shows Qi's Innovation Score is 30.9/100 (36th 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 Qi?

Each dot is one of Qi’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). Qi’s own 10.9 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qi's grants concentrate

Qi Ding Technology Qinhuangdao Co, Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 60% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2023. By volume, Qi sits between Quantex Patents Limited and Quantum Source Labs Ltd..

Qi's three-year grant acceleration

Qi Ding Technology Qinhuangdao Co, Ltd. shows 1 grants in 2022–2024 against only 2 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.
