What this shows Kanto's Innovation Score is 49.7/100 (top 14% 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 Kanto?

Each dot is one of Kanto’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). Kanto’s own 12.1 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kanto's grants concentrate

Kanto Denka Kogyo Co., Ltd. is a focused PatentsView assignee: 35 CPC subclasses with 36.8% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2023 (8 grants) versus a trough of 1 in 2024. By volume, Kanto sits between Jamco Corporation and Kyorin Pharmaceutical Co., Ltd..

Kanto's three-year grant acceleration

Kanto Denka Kogyo Co., Ltd. shows 16 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.
