What this shows Zhuhai's Innovation Score is 50.7/100 (top 13% 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 Zhuhai?
Each dot is one of Zhuhai’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). Zhuhai’s own 11.5 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Zhuhai's grants concentrate
Zhuhai Access Semiconductor Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 81.3% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2019. By volume, Zhuhai sits between Yellowbrick Data, Inc. and Abloy OY.
Zhuhai's three-year grant acceleration
Zhuhai Access Semiconductor Co., Ltd. shows 21 grants in 2022–2024 against only 3 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.
