What this shows Yang's Innovation Score is 21.9/100 (9th 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 Yang?

Each dot is one of Yang’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). Yang’s own 8.3 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yang's grants concentrate

Yang JI Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 83.3% 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 2016 (2 grants) versus a trough of 1 in 2015. By volume, Yang sits between Xtera Communications, Inc. and Yichang Jingwei Textile Machinery Co., Ltd..

Yang's three-year grant acceleration

Yang JI Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
