What this shows JGC's Innovation Score is 30.9/100 (36th 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 JGC?

Each dot is one of JGC’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). JGC’s own 10.5 claims/patent is ABOVE the 6.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where JGC's grants concentrate

JGC Japan Corporation is a focused PatentsView assignee: 5 CPC subclasses with 50% of grants classified under B01D (Separation). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2020. By volume, JGC sits between JEN Sian Industrial Co., Ltd. and Jiangsu Hehui Power Tools Co., Ltd.

JGC's three-year grant acceleration

JGC Japan Corporation shows 3 grants in 2022–2024 against only 2 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.
