What this shows Japan's Innovation Score is 32.0/100 (40th 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 10.3 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Japan's grants concentrate

Japan Medical Device Technology Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 88.9% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Japan sits between Jungwoo Metal IND. Co., Ltd. and Jiangsu Comco Outdoor Products Co., Ltd..

Japan's three-year grant acceleration

Japan Medical Device Technology Co., Ltd. shows 3 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.
