What this shows LI's Innovation Score is 41.9/100 (top 32% 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 LI?

Each dot is one of LI’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). LI’s own 8.7 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where LI's grants concentrate

LI Yang Electric Machinery (DONGGUAN) Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 86.7% 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 2023 (4 grants) versus a trough of 2 in 2024. By volume, LI sits between LCI Italy S.R.L. and Liveleaf Holdings, LLC.

LI's three-year grant acceleration

LI Yang Electric Machinery (DONGGUAN) Co., Ltd. shows 9 grants in 2022–2024 against only 0 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.
