What this shows Japan's Innovation Score is 38.2/100 (top 41% 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 Japan?

Each dot is one of Japan’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). Japan’s own 18.2 claims/patent is ABOVE the 7.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Japan's grants concentrate

Japan Cooperation Center Petroleum is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C10G (Cracking Hydrocarbon OILS; Production OF Liquid Hydrocarbon Mixtures, e.g. BY Destructive Hydrogenation, Oligomerisation, Polymerisation ; Recovery OF Hydrocarbon Oils From Oil-shale, Oil-sand, OR GAS). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2015. By volume, Japan sits between J.D Components Co., Ltd. and Johnan Manufacturing Inc..

Japan's three-year grant acceleration

Japan Cooperation Center Petroleum shows 8 grants in 2022–2024 against only 7 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.
