What this shows Ojjo's Innovation Score is 50.9/100 (top 12% 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 Ojjo's grants concentrate

Ojjo, Inc. is a focused PatentsView assignee: 22 CPC subclasses with 70.3% of grants classified under F24S (Solar Heat COLLECTORS; Solar Heat Systems). Peak complete grant year is 2024 (17 grants) versus a trough of 1 in 2019. By volume, Ojjo sits between National Chi Nan University and Penumbra, Inc..

Ojjo's three-year grant acceleration

Ojjo, Inc. shows 36 grants in 2022–2024 against only 17 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.
