What this shows Delta's Innovation Score is 43.4/100 (top 28% 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 Delta's grants concentrate

Delta Kogyo Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 77.3% of grants classified under B60N (Seats Specially Adapted FOR VEHICLES; Vehicle Passenger Accommodation NOT Otherwise Provided FOR). Peak complete grant year is 2024 (10 grants) versus a trough of 1 in 2018. By volume, Delta sits between Compugen Ltd. and Deephaven Data Labs LLC.

Delta's three-year grant acceleration

Delta Kogyo Co., Ltd. shows 17 grants in 2022–2024 against only 12 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.
