What this shows LIH's Innovation Score is 43.4/100 (top 28% 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 LIH?

Each dot is one of LIH’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). LIH’s own 3.9 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where LIH's grants concentrate

LIH Yann Industrial Co., Ltd. is a focused PatentsView assignee: 32 CPC subclasses with 14.3% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2023 (7 grants) versus a trough of 2 in 2015. By volume, LIH sits between Kong Inc. and Maxwell Technologies, Inc..

LIH's three-year grant acceleration

LIH Yann Industrial Co., Ltd. shows 17 grants in 2022–2024 against only 14 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.
