What this shows Japan's Innovation Score is 35.0/100 (49th 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 15.2 claims/patent is ABOVE the 7.0 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 VAM & Poval Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 66.7% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, Japan sits between J-lok Co. and Jfxd TRX ACQ LLC.

Japan's three-year grant acceleration

Japan VAM & Poval Co., Ltd. shows 2 grants in 2022–2024 against only 4 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.
