How Japan’s 27.5 Innovation Score adds up
The same four weighted components behind every Innovation Score on PlainPatent: portfolio volume, grant velocity, technology breadth, and claim depth.

What this shows Japan's Innovation Score is 27.5/100 (24th 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 13.6 claims/patent is at or below the 14.5 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 Communication Accessories Manufacturing Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2023. By volume, Japan sits between J. Frank Schmidt & Son Co. and JDC Corporation.
Japan's three-year grant acceleration
Japan Communication Accessories Manufacturing Co., Ltd. shows 4 grants in 2022–2024 against only 10 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.
