What this shows Tokyo's Innovation Score is 39.6/100 (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 Tokyo?

Each dot is one of Tokyo’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). Tokyo’s own 9.9 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tokyo's grants concentrate

Tokyo Metropolitan Institute OF Medical Science is a focused PatentsView assignee: 15 CPC subclasses with 61.3% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2016. By volume, Tokyo sits between System General Corp. and TTP Plc.

Tokyo's three-year grant acceleration

Tokyo Metropolitan Institute OF Medical Science shows 6 grants in 2022–2024 against only 5 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.
