What this shows Japan's Innovation Score is 39.3/100 (top 38% 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 7.1 claims/patent is at or below the 16.3 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 OIL, GAS AND Metals National Corporation is a focused PatentsView assignee: 29 CPC subclasses with 71.7% of grants classified under C10G (Cracking Hydrocarbon OILS; Production OF Liquid Hydrocarbon Mixtures, e.g. BY Destructive Hydrogenation, Oligomerisation, Polymerisation ; Recovery OF Hydrocarbon Oils From Oil-shale, Oil-sand, OR GAS). Peak complete grant year is 2016 (15 grants) versus a trough of 1 in 2020. By volume, Japan sits between Instart Logic, Inc. and Kaspersky Lab, ZAO.

Japan's three-year grant acceleration

Japan OIL, GAS AND Metals National Corporation shows 2 grants in 2022–2024 against only 6 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.
