What this shows Rakuten's Innovation Score is 44.2/100 (top 26% 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 Rakuten's grants concentrate

Rakuten Kobo Inc. is a focused PatentsView assignee: 26 CPC subclasses with 85.9% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2018 (17 grants) versus a trough of 1 in 2022. By volume, Rakuten sits between Otto Bock Healthcare Products GmbH and Sio2 Medical Products, LLC.

Rakuten's three-year grant acceleration

Rakuten Kobo Inc. shows 2 grants in 2022–2024 against only 18 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.
