What this shows Japan's Innovation Score is 31.1/100 (37th 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 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 9.2 claims/patent is ABOVE the 7.0 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 Blue Energy Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under C10K (Purifying OR Modifying THE Chemical Composition OF Combustible Gases Containing Carbon Monoxide). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2017. By volume, Japan sits between JAM Packaging LLC and Japanese Organization FOR Medical Device Development, Inc..

Japan's three-year grant acceleration

Japan Blue Energy Co., Ltd. shows 2 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.
