What this shows Chief's Innovation Score is 26.0/100 (19th 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 Chief?

Each dot is one of Chief’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). Chief’s own 10.1 claims/patent is ABOVE the 8.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chief's grants concentrate

Chief Land Electronic Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 73.3% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2018. By volume, Chief sits between Centrica Hive Limited and Cibo Technologies, Inc..

Chief's three-year grant acceleration

Chief Land Electronic Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
