What this shows Tokyo's Innovation Score is 37.5/100 (top 44% 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 ABOVE the 9.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Tokyo's grants concentrate
Tokyo Metropolitan Industrial Technology Research Institute is a focused PatentsView assignee: 31 CPC subclasses with 35.7% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2016. By volume, Tokyo sits between Thornhill Scientific Inc. and Toray Fine Chemicals Co., Ltd..
Tokyo's three-year grant acceleration
Tokyo Metropolitan Industrial Technology Research Institute shows 3 grants in 2022–2024 against only 8 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.
