What this shows Japan's Innovation Score is 41.5/100 (top 33% 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 9.0 claims/patent is at or below the 15.6 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 Fine Ceramics Center is a focused PatentsView assignee: 35 CPC subclasses with 34.8% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2016. By volume, Japan sits between Intralinks, Inc. and Jiaxing Uphoton Optoelectronics Technology Co., Ltd..

Japan's three-year grant acceleration

Japan Fine Ceramics Center shows 5 grants in 2022–2024 against only 8 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.
