What this shows Lechat's Innovation Score is 32.6/100 (42nd 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 Lechat?

Each dot is one of Lechat’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). Lechat’s own 11.0 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lechat's grants concentrate

LeChat is a focused PatentsView assignee: 9 CPC subclasses with 38.5% of grants classified under A45D (Hairdressing OR Shaving Equipment ; Equipment FOR Cosmetics OR Cosmetic Treatments, e.g. FOR Manicuring OR Pedicuring). Peak complete grant year is 2019 (12 grants) versus a trough of 1 in 2024. By volume, Lechat sits between Lingdong Technology (BEIJING) Co. Ltd. and Mercari, Inc..

Lechat's three-year grant acceleration

LeChat shows 7 grants in 2022–2024 against only 18 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.
