What this shows Japan's Innovation Score is 39.0/100 (top 39% 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 7.0 claims/patent is at or below the 7.2 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 Chain Terminal Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 40% of grants classified under H02G (Installation OF Electric Cables OR Lines, OR OF Combined Optical AND Electric Cables OR Lines). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Japan sits between Jamm Technologies, Inc. and Jason Toys & Electronics Co., Ltd.

Japan's three-year grant acceleration

Japan Chain Terminal Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
