What this shows L&f's Innovation Score is 37.1/100 (top 45% 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 L&f?

Each dot is one of L&f’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). L&f’s own 14.7 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where L&f's grants concentrate

L&F Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2018. By volume, L&f sits between Kostal of America, Inc. and Laboratoires Urgo.

L&f's three-year grant acceleration

L&F Co., Ltd. shows 7 grants in 2022–2024 against only 5 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.
