Where Inalfa's grants concentrate

Inalfa Roof Systems Group B.V. is a focused PatentsView assignee: 36 CPC subclasses with 94.1% 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 (20 grants) versus a trough of 5 in 2019. By volume, Inalfa sits between Chemocentryx, Inc. and Metra Electronics Corp..

Inalfa's three-year grant acceleration

Inalfa Roof Systems Group B.V. shows 53 grants in 2022–2024 against only 19 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.
