What this shows Leer's Innovation Score is 56.2/100 (top 6% 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.

Where Leer's grants concentrate

Leer Group is a focused PatentsView assignee: 16 CPC subclasses with 51.2% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2023 (12 grants) versus a trough of 1 in 2015. By volume, Leer sits between KAI R&D Center Co., Ltd. and Miyakoshi Printing Machinery Co., Ltd..

Leer's three-year grant acceleration

Leer Group shows 23 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.
