What this shows Kaijo's Innovation Score is 36.4/100 (top 46% 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.

Does more volume mean deeper claims for Kaijo?

Each dot is one of Kaijo’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Kaijo’s own 6.6 claims/patent is at or below the 7.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kaijo's grants concentrate

Kaijo Corporation is a focused PatentsView assignee: 22 CPC subclasses with 75% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2015. By volume, Kaijo sits between Jiangsu Zhongheng PET Articles Joint-stock Co., Ltd. and Kingsway Enterprises (UK) Limited.

Kaijo's three-year grant acceleration

Kaijo Corporation shows 7 grants in 2022–2024 against only 11 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.
