What this shows Japan's Innovation Score is 32.9/100 (43rd 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 7.6 claims/patent is at or below the 12.6 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 Superconductor Technology, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 85.7% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2024. By volume, Japan sits between JM Energy Corporation and Josh.ai, Inc..

Japan's three-year grant acceleration

Japan Superconductor Technology, Inc. shows 4 grants in 2022–2024 against only 5 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.
