What this shows Kohjin's Innovation Score is 29.1/100 (30th percentile 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 Kohjin?

Each dot is one of Kohjin’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). Kohjin’s own 8.6 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kohjin's grants concentrate

Kohjin Life Sciences Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 50% of grants classified under A23L (Foods, Foodstuffs OR Non-alcoholic Beverages, NOT Otherwise Provided FOR; Preparation OR Treatment Thereof). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2020. By volume, Kohjin sits between KMB Telematics, Inc. and Kontek Industries, Inc..

Kohjin's three-year grant acceleration

Kohjin Life Sciences Co., Ltd. shows 1 grants in 2022–2024 against only 5 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.
