What this shows Lube's Innovation Score is 23.6/100 (12th 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 Lube?

Each dot is one of Lube’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). Lube’s own 5.8 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lube's grants concentrate

Lube Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 37.5% of grants classified under F16N (Lubricating). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2022. By volume, Lube sits between Lohmann & Rauscher GMBH & Co., KG and Luxcreo (BEIJING) Inc..

Lube's three-year grant acceleration

Lube Co., Ltd. shows 1 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.
