What this shows Sagami's Innovation Score is 47.5/100 (top 18% 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 Sagami?

Each dot is one of Sagami’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). Sagami’s own 12.0 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sagami's grants concentrate

Sagami Chemical Research Institute is a focused PatentsView assignee: 23 CPC subclasses with 41.2% of grants classified under C07F (Acyclic, Carbocyclic OR Heterocyclic Compounds Containing Elements Other Than Carbon, Hydrogen, Halogen, Oxygen, Nitrogen, Sulfur, Selenium OR Tellurium). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2019. By volume, Sagami sits between S.M.E. Products LP and Schneider Electric Solar Inverters USA, Inc..

Sagami's three-year grant acceleration

Sagami Chemical Research Institute shows 4 grants in 2022–2024 against only 2 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.
