What this shows Zhuhai's Innovation Score is 39.8/100 (top 37% 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 7.0 claims/patent is ABOVE the 6.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhuhai's grants concentrate

Zhuhai Bojay Electronics Co. Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2023. By volume, Zhuhai sits between Zetagen Therapeutics, Inc. and Zodiac Seats UK Limited.

Zhuhai's three-year grant acceleration

Zhuhai Bojay Electronics Co. Ltd. shows 7 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.
