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 1.1 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 L&f's grants concentrate

L&F Plastics, Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 1.1% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2024 (17 grants) versus a trough of 1 in 2020. By volume, L&f sits between JGC Catalysts and Chemicals Ltd. and National University Corporation Kagawa University.

L&f's three-year grant acceleration

L&F Plastics, Co., Ltd. shows 44 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.
