What this shows Japan's Innovation Score is 56.2/100 (top 6% 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 9.8 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 Japan's grants concentrate

Japan Atomic Energy Agency is a focused PatentsView assignee: 35 CPC subclasses with 21.4% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2019. By volume, Japan sits between Ironwood Pharmaceuticals, Inc. and Jiangsu Academy of Agricultural Sciences.

Japan's three-year grant acceleration

Japan Atomic Energy Agency shows 8 grants in 2022–2024 against only 3 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.
